Functions The load is lifted or lowered by pulling one of the chain falls of the endless hand chain of the hoist. A load pressure brake prevents automatic lowering of the load after releasing the hand chain. In combination with hand geared trolleys, the trolley is moved to the left or to the right side by pulling the hand chain. -
Page 13: Tools
Generally, additional lifting gear (e.g. fork lift, lifting platforms) will be required for the assembly. These must take the weight of the devices securely. Tools Control Only people that are familiar with the operation of the lifting devices and cranes may be entrusted with their operation. -
