Rough-terrain trucks — Safety requirements and verification — Part 8: Requirements for trucks designed for towing

This document specifies safety requirements and verification for rough-terrain variable-reach trucks and slewing rough-terrain variable-reach trucks as defined in ISO 10896-1 and ISO 10896-2 (hereafter referred to as “trucks”) designed for towing trailers or towed equipment or both (hereafter referred to as “towed vehicles”) with a maximum design speed less than or equal to 40 km/h, taking into account the intended use as well as the reasonably foreseeable misuse.

NOTE Local regulations can apply when trucks are used to tow towed vehicles on public roads.

The significant hazards dealt with in this document are mechanical hazards (see ISO 12100:2010, Table B.1) due to:

— acceleration, deceleration;

— instability;

— kinetic energy;

— machinery mobility;

— stored energy.

This document is not applicable to trucks intended to tow a towed vehicle equipped with a:

a) complex electronic control system for braking or electronically-controlled braking system (EBS);

b) braking system where the braking force applied to one wheel can be different from the braking force applied to the other wheel of the same axle (differential braking system);

c) braking system where the energy source
