Chapter 7 

•  Before installation, be certain to understand the electrical functioning of the crane, including the 

order and relationship of motions and contactors. 

•  Fall prevention devices should be used when anyone is working on the crane. 

•  The receiver must be securely attached and located where it will not be hit by any moving part of 

the building, crane, or load. 

•  The crane must be equipped with limit switches for each motion and a main power contactor that 

cuts off all power to the motors of the crane when it is de-energized. 

•  Special care must be taken for magnets and other load-carrying devices; ensure that if the crane 

is de-energized the load remains supported. 

•  The receiver must be located so that it receives sufficient signal strength from the transmitter. 

The preferred location is in sight of the operator. However, if this is not possible (e.g., if the 
receiver unit is in a metal box), then an external antenna should be mounted such that it is in 
sight of the operator. 

•  Test the unit before placing it in service. If the crane does not work exactly as intended, fix the 

problem and test it again.
