Originally designed to effortlessly replace the manual theatre counterweight system, ASM engineers designed the impressive HCWA TwinMaster series with a slim design of less than 200 mm. The completely redundant hoist is driven by the patented double worm gear by means of extremely durable steel band, which ensure particularly smooth and silent running of the rope drum. All HCWA TM come with two independent silent theatre brakes.
Depending on model, each hoist has a standard lifting capacity up to 1,000 kg and a fixed or variable speed up to 2.0 m/s*. Travel of up to 34 meters is possible*.
The HCWA TM range feature a silent noise level of only 45 dB(A)1m. It is 50% lighter than other scenery hoists, reducing forces on existing stage structures.
As the scenery hoist is driven by two independent motors, the reduction gear operates on two channels and thus offers maximum safety. The HCWA TM is designed in strict conformity with the DGUV V17 and EN 17206 regulations. Above that, the HCWA scenery hoist has a gearbox integrated safety catch and safety standards that are unique in the market. The HCWA range has been developed to allow installation to conform local and international safety regulations and in combination of almost all professional controls.
The HCWA TM hoist is mechanically completely redundant which offers a solution in countries where high torque brakes are required by national regulations.
The HCWA TM scenery hoist has not only proven to be a magnificent space saver on fly loft installations, but it allows flexible hanging on head pulley structures or on wall installations. The HCWA TM hoist is designed for flexible installations positions. Mechanical coupling of two hoists is possible.
All HCWA hoists are made to be SIL 3 ready and can be coupled with a SIL3 control, such as ASM GENESIS SIL3 control.
