AS 5144.2:2018 Industrial trucks—Safety requirements and verifcation
4.4.3.1  Steering direction
The following applies.
a) For trucks with a steering‑wheel control, clockwise rotation of a steering wheel shall steer the truck to the right when the truck is travelling in the forward direction.
b) On trucks with a crab‑steer mode (all wheels on the truck turn in the same direction), clockwise rotation of the steering wheel shall move the truck to the right when the truck is travelling in the forward direction and to the left when travelling in the reverse direction.
c) On trucks where the steering is controlled by means of a single lever controller, moving the lever to the right shall cause the truck to be steered to the right when the truck is travelling in the forward direction. If a reversible control unit or dual controls are fitted, moving the lever to the right shall also steer the truck to the operator’s right when the truck is travelling in reverse with the operator facing in that direction.
4.4.3.2  Failure of power supply
In the event of an interruption of the power supplied to the steering system (including a dead motor or engine) it shall be possible to maintain the path being steered until the truck is brought to a controlled stop.
4.5.3.1  Tank isolation
If a fuel tank is within or adjacent to the engine compartment and excessively high temperatures may occur, the tank and/or filling arrangement shall be isolated from the electrical and exhaust systems by suitable protection, e.g. a separate enclosure or baffles. The tank location and facilities for filling shall be such that spillage or leakage will not drain into the engine or operators compartment nor onto unprotected electrical or exhaust system parts.
4.5.4.1  Engine covers
An enclosed engine compartment shall satisfy fan guarding requirements when the manufacturer’s recommended routine maintenance is performed with the engine off. If a fan can start (e.g. temperature switch) when the engine is off, the fan shall be guarded. A safety warning sign shall be provided, and included in the instruction handbook (see 6.2). Warnings shall comply with 6.3.4.5.
