Introduction

This section proposes technical requirements and recommendations for lifting equipment electrical equipment in order to promote improvement.

---Safety of personnel and property;

--- Control response consistency;

---Maintenance convenience.

High performance should not be achieved by reducing the above basic requirements.

Part 32. Lifting machinery technical conditions

1 Scope

This part of GB/T 5226 applies to electrical and electronic equipment and systems related to lifting appliances.

Note 1. In this part, the term "electrical" includes both electrical and electronic (ie, electrical equipment refers to both electrical equipment and electronic equipment).

Note 2. In this section, the term "personnel" refers to any individual and any person who is assigned to use or manage lifting appliances by the user or his agent.

The equipment contained in this section starts from the power supply access point (crane power switch) of the crane electrical equipment, including the crane

External power supply and control feeder systems, such as flexible cables or collector wires or trolley wires (see Figure 3).

Note 3. See IEC 60364 for building power installation requirements.

This section applies to electrical equipment and its components, the line voltage does not exceed 1000V (ac) or 1500V (dc), rated frequency is not exceeded

Over.200Hz.

Note 4. For high voltage requirements see IEC 60204-11.

Additional and special requirements may be specified for electrical equipment used in lifting appliances in the following environments.

--- For outdoor use (ie outside the building or other protective structure);

--- Used to handle or transport potentially explosive substances (eg paint or sawdust);

--- For potentially explosive materials or flammable gases;

--- For mines.

For this part, lifting machinery includes various types of cranes, various types of winches, and railroad roadway stacker cranes, including

The following types of products.

---Bridge crane;

---Mobile cranes;

---Tower cranes;

---Portable cranes;

---Gantry crane;

--- Shore cranes;

--- Floating cranes;

--- various winches;

---Hoist and accessories;

--- Loading cranes;

---Cable cranes;

--- Load holding device;

---Railway stacking cranes;

--- Monorail transport system;

--- Straddle vehicles;

---Tire gantry cranes (RTGs).

This section refers to the selection and installation of electrical equipment components, but does not involve the components themselves.
