scope:

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 the context of this Standard, the term "person" refers to any individual and includes those persons who are assigned and instructed by the user or user's 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, for example, flexible cables or conductor wires or conductor bars (see figure 3).

NOTE 3 For the requirements for the electrical supply installation in buildings, see JIS C 60364.

This Standard is applicable to equipment or parts of equipment not exceeding 1 000 V a.c. or 1500 V d.c. between lines and with nominal frequencies not exceeding 200 Hz.

NOTE 4 For equipment exceeding 1 000 V a.c. or 1 500 V d.c. and not more than 36 kV, the requirements shall be as given in JIS B 9960-11.

Additional and special requirements can apply to the electrical equipment of hoisting machines including those that

- are intended for use in open air (i.e., outside buildings or other protective structures);

- handle or transport potentially explosive material (for example, paint or sawdust);

- are intended for use in potentially explosive and/or flammable atmospheres;

- are intended for use in mines.

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;

- loader cranes;

- container 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 Creation.

NOTE 5 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

IEC 60204-32: 2008 Safety of machinery-Electrical equipment of machines- Part 32: Requirements for hoisting machines (MOD)

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ lEC Guide 21-1.
