A SPECIAL type of semi-trailer, intro.:I-1. duced in New Zealand 'bye years ago, has proved so versatile that today nearly 200 are used for hauling timber, coal, lime, fertilizers and gravel for distances up to 50 miles: Known as Tipulators, the bodies are built by Tapper Transport Engineering, Ltd., PO. Box 3561, Auckland, and employ standard Telehoist rams and hydraulic tipping equipment.
The ability of the ram to hold the body in any required position up to 50° is of advantage during the spreading of gravel, as by regulating the angle of tip from the cab and driving at a steady 15 m.p.h., gravel can be laid to a required thickness. The semi-trailer carries a load of 8 cu. yd.
A new metering valve is used in the vacuum braking system and the tailgate opening is also vacuum-operated. The vehicles are jig-built from standard components, giving interchangeability of parts throughout New Zealand.
