Part 36 Mining

Section 591 Design safety factors

(1) An employer must ensure that a rubber-tired, self-propelled machine has

(a) shock-absorbing seats,

(b) a fail-safe means of preventing unintentional movement when the machine is parked, and

(c) an interlock system that prevents the engine from starting when the transmission is engaged.

(2) An employer must ensure that all haulage trucks fitted with rear dump boxes

(a) have a calculated centre of gravity, and

(b) will maintain all wheels in contact with the ground during normal operation when loaded to the manufacturer’s specified maximum load weight.

(3) If the load characteristics cause the front wheels of a rubber-tired, self-propelled machine to lift off the ground, an employer must develop procedures to protect workers from the related hazards.
