Introduction

During the intended operation, self-propelled agricultural machinery with a ride-on operator (driver) may face the danger of tipping or tipping over. wind

Risk assessment is used to determine whether the risk applies to a particular machine and, where appropriate, actions to avoid or minimize rides

protective measures against this danger. For many machines, this risk assessment will be reflected in the specific product standard requirements.

The risk assessment takes into account the operating conditions in which the machine is intended to be used, the physical characteristics of the machine, the skills required to operate the machine, and the possible effects of rollover

or any other parameter of dumping risk.

GB/T 41603 "Stability Evaluation of Self-Propelled Agricultural Machinery" consists of two parts.

--- Part 1.Principles;

--- Part 2.Determination and test procedures for static stability.

Evaluation of the stability of self-propelled agricultural machinery

Part 1.Principles

1 Scope

This document specifies the design and manufacture of self-propelled ride-on agricultural machinery, and the use of the machine under the manufacturer's intended and foreseeable conditions

Criteria for evaluating the hazardous stability of a device when a rollover, tipping, or both rollover and tipping occurs. This document also specifies the manufacturer's

Type of information on safe operations (including residual risks).

This document does not apply to the following situations.

--- Machines with no-load mass less than 400kg;

--- Machines that have rollover or tipping protections specified in other specific standards, such as agricultural tractors, forestry tractors;

--- Hazards associated with road transport operations;

--- Free fall events;

--- Rollover caused by collision.

This document does not apply to machines manufactured prior to the publication of this document.
