Introduction

Stability is one of the important indicators for assessing the safety of industrial vehicles. The counterbalanced forklift is a product with a large volume and a wide range of industrial vehicles.

Over the past few years, the demand for counterbalanced forklifts at home and abroad has continued to increase. In order to ensure the safety of counterbalanced forklifts, it is necessary to stabilize such products.

The performance verification requires standardization and unification, and realizes that my country's counterbalanced forklift products are in line with international standards.

GB/T 26949 "Industrial Vehicle Stability Verification" aims to establish the stability and verification of industrial vehicles defined in ISO 5053-1

method. GB/T 26949 is proposed to consist of the following parts.

--- Part 1.General;
