Safe Working Load is a term that applies not just to Aluminium movable scaffolding but to many construction industries and equipment’s. The safe weight-bearing capacity of the equipment, combining both the equipment itself and the weight of workers and materials. Exceeding such limits can create hazardous workplaces, so SWL should be understood before work begins.
When considering how to calculate the required safe working load of Aluminium Movable scaffolding, there are six main variables – dead load, live load, static load, dynamic load, wind load, environmental load.
Dead load is the weight of Aluminium movable scaffolding tower and its components before it is loaded
Live load is the weight of equipment and worker on the Aluminium movable scaffolding Ladder (per bay)
Static load is load that doesn’t move
Dynamic load is the load/force made by a moving load, on a structure or component
Wind load is the additional load against the scaffold created by the force of wind on a structure
Environmental load is the weight of environmental factors such as debris, water, snow and dust that may be on the scaffolding
With all factors considered, Aluminium movable scaffolding is erected and certified to a particular load capacity adequate for the project to be carried out safely. It is also paramount that the client and their personnel abide by these load limits to avoid catastrophic failure, leading to possible injury or death.

There are several choices to make in selecting the right smoke/fire alarms to buy, the most important thing to remember is that smoke alarms save lives. For that reason, you should install a smoke alarm if your home does not have one. Installing additional smoke alarms throughout the house provides greater protection.
FIRE SAFETY ALARM contain different or multiple sensors : There are two main types of smoke alarms, which are categorized by the type of smoke detection sensor, ionization and photoelectric, used in the alarm. Each type of smoke alarm may perform differently in different types of fires. A smoke alarm may use multiple sensors, sometimes with a heat detector or carbon monoxide detector, to warn of a fire. Ionization detectors contain a chamber with two plates that generate a small, continuous electric current. When smoke particles enter the ionization chamber, the smoke particles disrupt the current flow, which triggers the alarm. Photoelectric detectors use a light beam and light receptor (photocell). When smoke particles are present between the light and receptor, depending on the type of smoke chamber configuration, the reduction or increase of light on the photocell sensor triggers the alarm.
FIRE SAFETY ALARMS may perform differently:- Both ionization and photoelectric detectors are effective smoke sensors, and even though both types of smoke detectors must pass the same tests to be certified to the voluntary standard for smoke alarms, they can perform differently in different types of fires. Ionization detectors respond quickly to flaming fires that give off heat and hot gases with smaller (sub-micron) combustion particles; photoelectric detectors respond more quickly to smouldering fires that give off larger combustion particles. There are combination smoke alarms that combine ionization and photoelectric detectors into one unit, called dual sensor smoke alarms The amount of time a person may have to escape depends on many factors, such as the type of fire, location of the fire, and the closest smoke alarm.
1. Detect Fire
Your fire alarm system is designed to detect fire in two main ways: smoke and heat. It should also have the capability of manual pull, in case a fire is observed before smoke or heat reaches the sensors of the system. Other systems are activated when movement in the sprinkler system is detected, indicating that the sprinklers are responding to a fire.
2. Alert Occupants
When the fire alarm system detects smoke, heat, or water movement, it alerts occupants of the building using both audible and visible alarms. These alarms will be bright, loud, obnoxious, and impossible to ignore, which help mobilize individuals to follow your evacuation plan. Using both types of alarms ensure that every person in the building is alerted.
Your building’s fire alarm system works in a third way to protect you: by reacting to potential risks using control measures. When the alarm is activated, some systems perform a set of tasks that help prevent fire and smoke from spreading as well as protect occupants, such as: automatically shutting doors in different zones, powering off ventilation and air conditioning, or redirecting elevators to bring cars to a designated level.
4. Notify Authorities
The fourth purpose of your fire alarm system is to notify authorities. This ensures the fire department is en route as quickly as possible, so they can respond and extinguish the fire before it becomes an even bigger threat.
Alarm. An alarm condition is exactly what was outlined in the section above. In the event that there is an immediate threat to life, property, or mission, the fire alarm system will sound the alarm, notifying occupants to escape, and letting the authorities know they need to respond.
Trouble. A trouble condition means that something is wrong with the system itself. Fire alarm systems necessarily employ a trouble condition to alert you or your building manager that while there may not be an immediate danger, you’ll need immediate inspection and repair of your system.
Supervisory. A supervisory condition — means that the system the fire alarm monitors has some sort of issue. This could signal anything from low or high pressure in the suppression system to a malfunction of the fire pump.
Generally if homes, shops and factories caught in fire then water is used to control fire. Water brings down the temperature of the combustible substance below its ignition temperature. The water vapour surrounds the combustible material, thus helping in cutting off the supply of air. So, that the fire is extinguished.
Fire produced by the burning of oil or petrol cannot be controlled by throwing water on it because water being heavier than oil, settles down the oil and oil continues to bum? So, now a day we can use different types of Fire Extinguisher for each type.
We know that there are 3 conditions necessary for producing and sustaining combustion.
Presence of a combustible substance.
Presence of a supporter of combustion.
Attainment of ignition or kindling temperature.
Thus, fire can be controlled by removing one or more of these requirements of fire control. The fire extinguishers also try to cut off the supply of air or bring down the temperature of the fuel or both, to control the fire. The combustible substance as such cannot be eliminated in most of the cases from the place of fire.
There are various types of fire extinguishers used for controlling a fire.
For Example:- Soda – acid fire extinguisher : Carbon dioxide liberated by the reaction of sulphuric acid with sodium bicarbonate solution comes out with a stream of liquid water at high pressure. Water puts off the fire by lowering the temperature of the combustible material below its ignition temperature and carbon dioxide cut off the supply of air to the combustible substance
1.Rapid combustion: The combustion in which the gas burns rapidly produces heat and light is called rapid combustion. For example: When a burning matchstick is brought near a gas burner and the gas tap is opened, the gas immediately starts burning with the production of heat and light. Eg. Petrol, LPG, spirit, etc.
2. Spontaneous combustion: The combustion in which no external heat is given is known as spontaneous combustion. For example: Burning of white phosphorus in air.
3. Explosion: The combustion in which large amount of gases are evolved with the production of a tremendous amount of heat, light and sound is called explosion. For example: When a cracker is ignited, a sudden reaction, oxidation process takes place, and in which at high speed large amount of gas is evolved with the production of tremendous amount of heat, light and sound.
Structure of a flame
In order to understand the structure of a flame, light a wax candle and watch its flame. Carefully note the different coloured zones in the flame. Starting from the base of the flame, a flame has four zones.
(1) Blue zone: It is near the base of the flame. Vaporised wax gets oxidised to carbon monoxide and carbon monoxide bums completely with a blue flame in this zone.
(2) Dark inner zone: Surrounding the wick is the dark zone. There is no burning in this zone. If we pass a wooden splinter through the dark zone of the flame, it comes out unscratched (unburnt) showing that there is no ‘burning’ in this zone. However, some =burnt wax vapours are present in this zone.
(3) Luminous zone: In this region of the flame hydrogen burns with a brilliant yellow luminous flame. Burning hydrogen combines with oxygen to form water vapour. Carbon also burns in this zone giving some luminosity to the flame and producing carbon dioxide. Some unblunt carbon particles are left which give rise to soot.
(4) Outermost non-luminous zone: This zone is poorly visible and is slightly blue. It is the hottest part of the flame where complete oxidation (burning) of the fuel is taking place.
There are many types of butterfly valves, including quick cut-off and continuous adjustment, Pneumatic butterfly valves , electric butterfly valves are mainly used for liquid and gas low pressure large diameter pipelines. It is suitable for occasions where the pressure loss is not high, flow adjustment is required, and the opening and closing requirements are fast; usually the temperature is below 300 ℃ and the pressure is below 40 kg (butterfly valves generally use low pressure, like domestic ones. It is rare to achieve CL600). The medium is generally used for water and gas, and the medium is not demanding. Granular medium can also be used.
As a sealed butterfly valve, it brought rapid development after the emergence of synthetic rubber, so it is a new type of shut-off valve. Butterfly valves were mainly used for low-pressure valves, and the valve seat was made of synthetic rubber. By the 1990s, due to increased exchanges with foreign countries, hard seal but, hard seal butterfly valves developed rapidly. At present, there are many valve factories that can produce medium-pressure metal-sealed butterfly valves stably, which makes the application field of butterfly valves wider.
The media that the butterfly valve can transport and control are water, condensate, circulating water, sewage, sea water, air, gas, liquid natural gas, dry powder, mud, fruit pulp and mixtures with suspended solids.
Butterfly valves are suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, about three times that of the gate valve, when selecting the butterfly valve, the influence of the pressure loss of the pipeline system should be fully considered, and the strength of the butterfly plate to withstand the pressure of the pipeline medium should also be considered. In addition, it is necessary to consider the limitation of the working temperature of the elastic valve seat material at high temperature. The structural length and overall height of the butterfly valve are small, the opening and closing speed is fast, and it has good fluid control characteristics. The structural principle of the butterfly valve is most suitable for making large-diameter valves. When the butterfly valve is required to control the flow, the most important thing is to correctly select the size and type of the butterfly valve so that it can work properly and effectively.
1. Generally, in throttling, regulating control and mud medium, the structure length is short and the opening and closing speed is fast (1/4 revolution). Low pressure cut-off (small pressure difference), butterfly valve is recommended.
2. The butterfly valve can be used when two-position adjustment, narrow passage, low noise, cavitation and vaporization phenomenon, a small amount of leakage into the atmosphere, and abrasive media.
3. When the butterfly valve is used under special conditions, such as throttling adjustment, or strict sealing requirements, or severe wear, low temperature (cryogenic) and other operating conditions, it is necessary to use a specially designed metal seal with a triple eccentric or double eccentric adjustment device Special butterfly valve for ground.
4. The centerline butterfly valve is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, and oil that require complete sealing, zero gas test leakage, high life requirements, and working temperature of -10℃~150℃ And various acid and alkali and other pipelines.
5. The soft-sealed eccentric butterfly valve is suitable for two-way opening and closing and adjustment of ventilation and dust removal pipelines. It is widely used in gas pipelines and waterways in metallurgy, light industry, electric power, and petrochemical systems.
Articulating boom lifts have a small move, but a big reach. They’re a Z-style aerial lift, meaning the boom sections of their arm can move independently so you can maneuver the next section to go around or over obstacles. For this reason, they’re sometimes called up-and-over booms.
They’re ideal for hard-to-reach and small areas because of their design, zero tail swing and small base. Many articulating lift rentals are also compatible with boom extensions or a jib. These extensions let you add another section to extend your reach even further.
Other compatible accessories for boom lifts that can make your job easier include:
Our boom lifts for rent are either battery- or diesel-powered. Different power options help you meet your project needs. Indoor projects in a closed area, for example, benefit from a battery-powered articulating boom rather than a diesel-powered one.
If your next project includes tight spaces and obstacles, then an articulating boom lift is likely the right lift to get the job done.
Small contractors and businesses rent boom lifts for a variety of reasons. Some of the most common uses of up-and-over booms include:
Mechanical, electrical or other maintenance work
Industrial facilities, like a steel or automotive plant, often need an articulating boom lift because their building has piping and machinery that can make some areas tough to reach during seasonal maintenance. Other conditions for renting an articulating boom lift include:
Congested or tight work areas that would be difficult for other lifts to reach
Short-term, seasonal or infrequent need of an up-and-over lift
Indoor projects with various obstacles
Renting an articulating boom lift is also helpful if you’re looking to lower your maintenance and storage costs, as well as the time you spend repairing and maintaining your equipment. If a business only does seasonal maintenance, for example, owning an up-and-over lift is more time-consuming than renting one.
Telescopic boom lifts are engineered to offer greater horizontal outreach than any other type of aerial platform, a super boom can be especially useful at jobsites like an oil and gas refinery, where workers need to not only consider height, but horizontal reach when trying to work around pipes and tall structures to access hard-to-reach areas. Other utilities also have similar limitations that can be overcome by big booms with their sizable range of motion. Some sites have found that keeping a big boom on site can cut back on time needed for repairs, which can be critical when trying to maintain energy supplies for customers. Other tasks including bridge inspections or ski lift maintenance also benefit from the horizontal reach of a telescopic, high-reaching boom. The Genie SX-135 XC boom lift, for example, has a horizontal reach of up to 90 ft (27.43 m), which means the chassis of the boom can be set up on stable, even ground while workers inspect a bridge over a road or river, or fix a ski lift on a slope. When selecting the right equipment for your extreme, high-reaching application, picking the right equipment is critical, as it is with any other application. Here are a few more things to consider when determining which big boom is the right machine for your job:
First one is Weight. Think about what kind of materials or equipment you’ll need. Heavy-lift Genie XC models, with an industry-leading dual lift capacity of 660 lb (300 kg) unrestricted and 1,000 lb (454 kg) restricted, can access jobs up to 141 ft (43.15 m) with the SX-135 XC.
Second one is Space. It’s not just about the height and reach once you’re inside a space. Also, consider how to get the equipment to the work site. Genie offers a Building Information Modeling (BIM) library that can help customers determine how to get a machine to where it’s needed, even before the boom arrives on site.
Third one is Specialization. A telescopic boom Lift used for glass installation, for example, may need different options than one used for welding or general construction. And, with a variety of boom lift options and accessories that are compatible with even higher-reaching Genie booms, each boom can be adapted to meet the needs of specific work sites, safely optimizing productivity.
your project is residential and won’t require height, mobility means it may not be an issue. But if it does require some height, then having a fixed structure will give you more options when it comes to getting up onto the roof of a building quickly and safely. Either way, make sure to ask us about our range of services so that we can help guide your decision in selecting exactly what kind of aluminium scaffold is right for each step of your build process.
The most common type of aluminium scaffolding is a mobile tower, which can be assembled and disassembled at any desired location. Mobile scaffolding towers are lightweight structures that offer many advantages over traditional scaffolds for construction projects. If you’re looking to save money on your next building project or want more flexibility in where you construct it, then learn about the cost benefits and other features offered by these versatile models today!
One of the best ways to save money on scaffolding is to use mobile scaffolding towers, which are much more cost-effective when it comes to upfront costs. If you don’t need a higher structure and just want something simple for low-level work like painting or window washing, then these will be perfect! Mobile scaffolds can also be used in many other situations as well – even if they’re not structurally necessary at first glance! There are a lot of options when it comes to scaffolding, but mobile towers can be the most cost-effective choice for those with smaller budgets. If you’re not looking at high structures or very long spans, then purchasing an entire mobile scaffolding tower system could end up costing more than if you just purchase some heavy-duty tripods and built your frames around them instead! Mobile scaffolding may seem like they would only be used in low elevation projects or on small jobs that don’t need anything special beyond what their standard set includes – think short buildings without any major heights that require complex support systems. But these types of mobility devices won’t break the bank either way since buying equipment is always going to have upfront costs no matter how much or If you’re working on a job site where your scaffolding can’t be too high, then it’s worth considering mobile scaffold. You’ll find that the upfront costs to purchase this type of equipment are much smaller than if you invest in complete full-size structures – which may not always suit your needs. Mobile scaffolds have other advantages as well; they’re very versatile and useful for jobs with different heights requirements or places with limited access points such as bridges or buildings close to water!
Mobile scaffolding tower make it simple for person’s to erect, strip and move the structure from place to place. Safety becomes an issue because people have to hand things up and down as they go along – which is a high risk. For any work at height closer than 2 meter (6 feet) above ground level to be considered low risk – all those working on that section need training first. Mobile scaffold towers can be assembled within 10 minutes.
Having a fire sprinkler system installed has a number of value and fire protection benefits. Sprinkler Systems are usually most effective when they are automatic suppression based. Benefits of installing fire sprinklers is that they can help protect and save all the occupants of the property. It’s essential to protect your property in any way you can.
By having a fire sprinkler system installed along with traditional methods such as smoke alarms you’ll help to protect both your property and the people in it. Properties that use both fire alarms and suppression systems reduce the risk of fire related death by 82%.
Compared to the damage fires can cause, free sprinklers are a cost effective way to protect both your physical property and the people living or working there. Most fire sprinkler systems cost a couple of percent of the overall property value. If you can afford a new kitchen, then you can afford to have a fire protection system fitted too.
Active fire sprinklers eliminate the possibly or people becoming trapped in a property, when a fire breaks out. Even without a clear fire exit, sprinklers can help to create a path, so people can escape safely. Using a combination of alarms, sprinklers and extinguishers is the best way to keep your building and the people in it safe in the event of a fire.
When the fire brigade sprays water into your property, it can cause extensive amounts of damage to both the visual appearance and to the structure of the property. Sprinklers installed in properties only use a minimum amount of water, meaning less damage will be caused when they go off compared to a fire engines hose.
Most types of fire sprinklers require very little maintenance and they typically continue running smoothly with only their annual maintenance check. Most installers also offer maintenance checks once or twice a year where they will test the value so see how the system is operating.
Reduces the Insurance Cost : Whether you’re a home or business owner, it’s likely you’ll be paying some type of insurance to protect your property in the event of damage. Claiming on these policies can be costly in the long run especially once you’ve claimed on them. Insurance premiums can be reduced by up to 15% when you have sprinklers installed in your property. That must be a benefit of installing fire sprinklers
Whilst there may be an upfront cost to pay out when you first have the system installed, it could be worth it when if you every sell your property. Properties using fire sprinklers are a much more attractive purchase for any type of buyer.
Now a day’s electric scissor lift is usually powered by lead-acid batteries, which have several lead plates in the acid bath. This technology has been the choice for batteries for over 150 years. But following in the footsteps of electric vehicles, including golf carts and cars, the scissor lift has now begun to follow lithium-ion battery technology.
In the 1980s, lithium ion technology became popular among consumers for its ability to efficiently operate small electronics such as cell phones, laptops and cordless devices. Equipped with Li-ion technology, these batteries provide power and charge using the exchange of lithium ions.
Today’s lithium ion technology for Scissor Lift has evolved to power and charge small objects in those early days, and with new formulas it now offers more robust energy and charge, enabling manufacturers to use it for small and medium-sized construction equipment. Such as scissors lift. For example, the lithium ion battery option for the Genie-1930 (North American model) and GS-1932 (EMEAAR model) scissor lifts is made of a lithium-iron phosphate compound (commonly referred to as LFP) which is a proven battery chemistry. Ideal for required rental applications and required performance in workplace environments.
To further enhance the performance of the new Genie lithium ion battery, we have incorporated battery heaters in the design of this new option to provide reliable and uniform operation at temperatures up to -20 ° F (-29 C).
All of these engineering advances in lithium ion battery technology translate into significant advantages of this technology when used in scissor lifts compared to traditional lead-acid battery options, including significant reduction in total franchise cost and improved emission workplace performance. For example, battery maintenance and irrigation are eliminated by comparison with lead-acid batteries – saving time and money.
In addition to requiring minimal maintenance, Genie lithium ion battery packs reduce the frequency of battery changes over the life of slab scissors, thanks to their longevity properties. Developed to meet customer demand for innovative new equipment, the new Genie Lithium Ion Battery Technology solution offers quick, efficient charging and long battery life, making Genie GS scissor lifts an environmentally friendly option.
