It incorporates two braked geared motors, a four-way limit box with BGV-C1 rating and optional encoder and a safe working load of up to 500kg. Its control system provides fixed or variable speed up to 10 metres per minute via a touch screen HMI unit and a switching power matrix enables two inverters to control up to 10 hoists via a single 13A or 6A 240v supply. It can be mounted either directly onto a grid or fixed to roof steels so that no lateral load is placed on the building walls. The suspension pulleys do not have to be aligned with the roof steels as the truss distributes the load to them.
