Introduction

With its unique structure and a variety of attachments that it can be equipped with, off-road forklifts are capable of working on many different types of vehicles: The application is extremely wide, and foreign countries already have a complete technical standard system for off-road forklifts: At present, some domestic manufacturers have entered this field one after another: area: This document lays a technical foundation for the realization of our country's off-road forklift products in line with international standards and the elimination of technical trade barriers: GB/T 42784 aims to establish the test method for the field of view verification of off-road forklifts, and is intended to be composed of two parts: --- Part 1: Telehandlers: The purpose is to specify the test method for verifying field of view of off-road telescopic forklifts: --- Part 2: Off-road type rotary telescopic forklift: The purpose is to specify the test field of view of the cross-country rotary telescopic forklift truck: test method: The "scope" of this document identifies the machinery involved and the hazards, hazardous states or hazardous events that may result: This document is a Class C standard specified in GB/T 15706: When the requirements of Category C standards are different from those of Category A or B standards, for machinery designed and manufactured according to Category C standards, Category C Standard requirements take precedence over other standard requirements: Test method for verification of field of view for off-road forklifts Part 1: Telehandlers

1 Scope

This document specifies the boundaries and radii of a 1m rectangle around an off-road telehandler for determining and evaluating the operator's field of view Static test method on a 12m field of view test circle: This document specifies the performance requirements for the field of view: This document applies to off-road models with the operator seat located on the left or center of the jib (excluding the operator seat located on the right side of the jib) Telescopic forklift (hereinafter referred to as "forklift"): This document does not apply to: --- Forklifts (reach stackers) designed to handle freight containers; --- Articulated telescopic wheel loader; --- Rotary forklift; ---Truck-mounted forklift: NOTE: The method used does not cover the full range of the operator's field of view, but provides information to help determine the acceptability of the forklift's field of view:
