This standard applies to the application of electrical and electronic equipment and systems to hoisting machines and related equipment.
Note 1: In this standard, the term electrical includes both electrical and electronic matters (i.e. electrical equipment means both the electrical and the electronic equipment).
Note 2: In this standard, the term person refers to any individual and includes those persons who are assigned and instructed by the user or his agent(s) in the use and care of the hoisting machine in question.
The equipment covered by this standard commences at the point of connection of the supply to the electrical equipment of the hoisting machine (crane-supply-switch) including systems for power supply and control feeders situated outside of the hoisting machine, e.g. flexible cables or collector wires or collector bars (see Figure 3).
Note 3: For the requirements for the electrical supply installation in buildings, see IEC 60364.
This standard is applicable to equipment or parts of equipment not exceeding 1000V a.c. or 1500V d.c. between lines, and with nominal frequencies not exceeding 200 Hz.
Note 4: Requirements for high voltage equipment are under consideration by IEC/TC 44 and IEC/TC 99.
Additional and special requirements can apply to the electrical equipment of hoisting machines that are used in potentially explosive and/or flammable atmospheres.
For the purposes of this standard, hoisting machines include cranes of all types, winches of all types, and storage and retrieval machines. The following product groups are included:
- Overhead travelling cranes;
- Mobile cranes;
- Tower cranes;
- Slewing luffing cranes;
- Gantry cranes;
- Offshore cranes;
- Floating cranes;
- Winches of all types;
- Hoists and accessories;
- Loader cranes;
- Cable cranes;
- Load holding devices;
- Storage and retrieval machines;
- Monorail hoists;
- Straddle carriers;
- Rubber tyred gantry cranes (RTGs).
This standard does not cover individual items of electrical equipment other than their selection for use and their erection.
