Introduction

Based on the manufacturer's instructions for use, working conditions, frequency of use, and applicable regulations, the mobile lifting work platform should be maintained regularly.

It should be noted that GB/T 30032 specifies the safety requirements for mobile lifting work platforms with special components. Assume that before starting work each day...

Check if the mobile lifting work platform is functioning properly. Only when all necessary control and safety devices are normal and in working order should the mobile lifting work platform be checked.

A mobile lifting work platform can only be put into operation after certain conditions are met. If a mobile lifting work platform is rarely used, it can be put into operation before work begins.

Conduct an inspection.

GB/T 30032 aims to establish guidelines for protecting personnel and objects from accident risks associated with the operation of special-purpose mobile lifting work platforms.

The rules do not repeat all general technical rules applicable to every electrical, mechanical, or structural component. It is proposed to consist of three parts.

---Part 1: Mobile lifting work platforms equipped with telescopic guardrail systems. The purpose is to specify the types of lifting work platforms equipped with telescopic guardrail systems.

The design, calculation, safety requirements and test methods of mobile lifting work platforms.

---Part 2: Mobile lifting work platforms equipped with non-conductive (insulating) components. The purpose is to specify the components equipped with non-conductive (insulating) components.

The design, calculation, safety requirements, and test methods for the mobile lifting work platform of the component.

---Part 3: Mobile Lifting Work Platforms for Orchards. The purpose is to specify the design and specifications for mobile lifting work platforms used in orchards.

Calculation, safety requirements and test methods.

1 Scope

This document specifies the design, calculation, and maintenance of mobile lifting work platforms (hereinafter referred to as "MEWPs") equipped with non-conductive (insulated) components.

Safety requirements and test methods. This document is used in conjunction with GB/T 25849.

This document applies to all types and specifications of MEWPs containing non-conductive (insulating) components, including designs and tests that meet manufacturing requirements.

Insulating components with specific electrical properties consistent with the manufacturer's nameplate. These MEWPs are intended for transporting personnel, tools, and equipment to the work location.

They then carried out their work on the working platform above the insulated arm section.

This document covers structural design calculations, the application of stability criteria, manufacturing, and the first use of MEWPs equipped with non-conductive (insulating) components.

The safety checks and tests conducted previously. Appendix A identifies various hazards associated with the use of MEWPs equipped with non-conductive (insulating) components, and provides...

Methods to eliminate or reduce these dangers have been developed.

No component of the MEWP described in this document comes into contact with any live parts of electrical equipment. This applies to the non-conductive arm section at the work platform end.

In the event of accidental contact, the electrical properties of the non-conductive (insulating) components of the MEWP provide electrical protection. If the MEWP is equipped with a chassis...

The insulation system provides electrical protection for people on the ground in the event of accidental contact with the system above.

This document does not apply to MEWPs designed for or capable of live-line work (see GB/T 9465). Electrical insulation class is determined by the operation of the distribution line.

Voltage (35kV and below) limitations.
