Stringent safety standards required by the Department Labour (DoL) force companies to find more effective ways of lifting people and goods safely to height, states lifting solutions company SA French.
SA French MD Quentin van Breda says that all Torgar hoists are designed and manufactured in accordance with European regulation EN-12159. This ensures that the Togar hoists comply with the highest safety compliance levels, says van Breda.
He comments that the use of the Torgar hoist is simple. He explains that it has a tower which is designed to be erected in manage- able sections as the building grows. At ground zero, the basic platform is erected in a protective cage with each section bolted on using conventional tools. The modular assembly system allows safe adaptation to irregular facades, says Van Breda.
He explains that the Torgar hoist has a standing height, and that the hoist must be anchored to the building when raised beyond its normal standing height to ensure increased operating performance and safety.
In the past, hoists were rope-driven, which raised questions pertaining to the safety of the systems, Van Breda comments. The Torgar hoist is rack-and-pinion-driven to ensure a safe and efficient way of controlling the ascent and descent of the hoist.
A second safety mechanism is incorporated at the top of the rack and pinion, at the peak height where a limit switch automatically overruns the operation and immediately halts the ascent of the platform on the ungeared section of the mast. The same applies in descent mode, where an integral limit switch and rubber buffers ease the platform to a safe stop should the drive system fail, Van Breda explains.
In addition, the Torgar hoist system is equipped with a number of features, including an electromagnetic brake, which will automatically kick in in the event of a power failure. The system also has an emergency brake that will be automatically activated should the first braking system fail.
Torgar hoists are made of heavy-duty, hot-dipped galvanised steel, making them suitable and safe in challenging weather conditions.
An electronic management system features a user-friendly control panel and an overload control system uses load cells to monitor the weight in the cabin to ensure the platform is not over-loaded. An optional variable- frequency drive provides the maximum torque in all operating modes, and allows for smooth starting and stopping with landing accuracy, Van Breda comments.
Torgar hoists have a lifting capacity of between 1 000 kg and 2 500 kg, a speed of 37 m a minute, and a power rating of 2 × 7,5 kW. The peak operational height for Torgar hoists is 100 m. Working platforms are available in 1,8 m × 2 m and 1,8 m × 2,7 m options. The folding access door has a width of 1,8 m, which will facilitate easy access of goods and personnel.
Van Breda says that Torgar systems are configured to suit specific contract requirements and platforms can be easily retrofitted should contract requirements change.
“These work platforms are easily and rapidly erected and dismantled, and offer a large working area in a short period of time. In addition, they are extremely versatile, offering safety and productivity benefits for customers in applications such as bricklaying, painting, concrete repairs, facade renovation and glass installation,” Van Breda concludes.
