Abstract: The present disclosure relates to a braking system and, more particularly, to a braking system for engaging a brake mechanism as a waiting brake for a load carrying vehicle. The braking system comprises first and second brake mechanisms. A controller is configured to control the operation of the second brake mechanism such that, if a predetermined fault condition is determined whilst the first brake mechanism is engaged, the controller automatically engages the second brake mechanism.

Abstract: The present disclosure relates to a method of disengaging a brake mechanism used as a waiting brake for a load carrying vehicle. In a vehicle comprising an automatic transmission system having at least one drive mode and a neutral mode, changing the mode of the transmission system from neutral mode to a drive mode automatically disengages the brake mechanism.

Abstract: The present disclosure relates to a braking system and, more particularly, to a braking system for engaging a brake mechanism as a waiting brake for a load carrying vehicle. The braking system utilises an electrohydraulic brake control mechanism comprising at least one automatic retard control valve to engage the brake mechanism, which is activated by a dual function apparatus which also controls another operation of the vehicle.

Abstract: A pulley plate, a pulley and a belt drive system are disclosed. Each include a pulley plate or a pulley having an inner surface adapted to be driven about an axis of rotation and having a perimeter. The inner surface additionally includes a plurality of belt-wiping grooves at least partially between the axis and the perimeter. The plurality of belt-wiping grooves are located or patterned in the inner surface so as to contact the belt in different locations to reduce wear on the wall of the belt. In one embodiment, the plurality of belt-wiping grooves are centered about the axis and are unequally circumferentially spaced from one another. In another embodiment, the plurality of belt-wiping grooves are centered about a center offset from the axis.

Abstract: A pulley plate for use with an opposing pulley plate wherein the plates are configured so as to receive a belt therebetween. The pulley plate includes an inner surface and an outer surface. The inner surface is opposite the outer surface and is adapted for facing the opposing pulley plate. A belt-wiping surface obliquely extends from the inner surface and is located so as to engage the belt. The belt-wiping surface wipes the edges of the belt to increase the friction between the pulley plate and belt and so increase the efficiency of the pulley.
