EN IEC 60204-32 (Electrical Equipment of Lifting Machines)
The standard that sets the requirements for the electrical and electronic equipment of lifting machines. Its scope is up to 1000 V AC and 1500 V DC, at supply frequencies not exceeding 200 Hz. Control circuits, interlocks, emergency stop and operator interface devices are dealt with within this scope.
The scope of the standard starts at the crane's supply disconnector and includes all the electrical equipment of the machine. Overhead, tower, mobile, portal and floating cranes; cranes and hoists; monorail systems and storage and retrieval systems are within scope.
The headings you meet directly in a radio remote control installation:
- Control circuits: separation of the control voltage from the power circuit, use of a control transformer.
- Interlocks: the arrangement that prevents the forward and reverse contactors from pulling in at the same time.
- Emergency stop: the layout and accessibility of the circuit.
- Limiting: limit switches going in series into the power circuit.
This standard has to be read together with the standard that gives the requirements specific to wireless control: one deals with the machine's electrical infrastructure, the other with the safety of the radio link. Since there is no declaration of conformity in the product data for AXI ST and SF sets, tie the conformity not to the product but to your own machine file.
