Introduction

Stability is one of the important indicators for assessing the safety of industrial vehicles. Reach and leg-type forklifts are the main products of industrial vehicles. A few years ago, the demand for reach and leg forklifts continued to increase at home and abroad. In order to ensure the safety of reach and leg forklift operations, it is necessary to adopt International standards regulate the stability verification of such products, so that my country's reach and leg-type forklift products can keep pace with international standards. GB/T 26949 "Verification of stability of industrial vehicles" aims to establish the stability and verification of industrial vehicles as defined in ISO 5053-1 Method. GB/T 26949 is intended to consist of the following parts. --- Part 1.General; --- Part 2.Counterbalanced forklift trucks; --- Part 3.Reach trucks and forklift trucks; --- Part 4.Pallet stackers, double-decker stackers and order pickers with a lifting height of no more than 1200 mm at the operator's position; --- Part 5.Side-mounted forklifts (single-sided); --- Part 7.Bidirectional and multidirectional forklifts; --- Part 8.Additional stability test for stacking operations with the gantry tilted forward and the load lifted; --- Part 9.Counterbalanced forklift trucks for handling freight containers of 6 m or more in length; --- Part 10.Additional stability test for stacking operations under side load conditions caused by power units; --- Part 11.Telescopic forklifts; --- Part 12.Telescopic forklifts for handling freight containers of 6 m or more in length; --- Part 13.Rough terrain forklifts with mast; --- Part 14.Rough terrain telescopic forklifts; --- Part 15.Counterbalanced forklift trucks with articulated steering; --- Part 16.Walk-behind vehicles; --- Part 17.Tractors, cargo and passenger carriers; --- Part 20.Additional stability tests for operation under load bias conditions; --- Part 21.Pickers with a lifting height of more than 1200 mm at the operator position; --- Part 22.Three-way stacking forklifts with or without operator position lift; --- Part 23.Truck-mounted forklifts; --- Part 24.Rough terrain telescopic forklifts. This document only covers reach trucks with tilting or non-tilting masts or forks, with a rated lifting capacity not exceeding 5000kg (with tilting masts or forks Stability test of telescopic mast or fork carriage and forklift with extended legs.
