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

A hazard assessment is used to determine whether this hazard should be considered in the context of a particular machine, and how to avoid or minimize this hazard to the operator

protection measures taken.

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 potential impact on rollovers

or any other parameter of tipping 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 2.Determination and test procedures for static stability

1 Scope

This document specifies the method for the determination of the center of mass of unloaded self-propelled agricultural machinery, the determination of the center of mass of fully loaded machines and combined working machines with accessories

method, and a method for the determination of the static roll angle.

NOTE. Requirements related to self-defense structures and ROPS will be given in other standards.
