The Goliath 4 and 6 wheelers
The 4-wheel 'Goliath' was designed to carry 12 tons, the 6-wheel version could carry 19 tons, the maximum legal gross load at the time. A variety of frame lengths and axle ratios were available, including tipper and trailer models.

The all-steel cab was a forward control type, with pressed steel doors and controlled drop windows. Twin panel windscreens of large area, together with two shaped quarter lights, afforded excellent all-round vision. The engine cowl was well sealed to reduce noise and vibration, and to eliminate fumes from the cab.

If required, a helical spring type attachment could be fitted for rear towing.
