LEX WILKINSON is fitting Rubery Owen Rockwell's Anchorlok ES• spring brake system to its 450-strong fleet of box van semi-trailers to speed the large number of trailer movements at its central parcel sorting and distribution complex in Nuneaton.
ale Anchorlok ES provides fully automatic positive braking to the axles when the emergency air line is disconnected so that the conventional handbrake, with its associated operating and maintenance problems, is no longer needed. If the air drains away the spring brakes are automatically applied.
The park brake can be applied with or without the tractive unit being attached by operation of the park valve or shunt valve.
A shunt valve is fitted as standard for occasions when the towing vehicles is not equipped with an air supply. With the park valve in the "brake off" position, operation of the shunt valve feeds air pressure to the emergency part of the valve which releases air to the service side of the spring brake.
