TWO vehicles have recently been completed by Bromilow and Edwards, Ltd., Bolton, for operation under arduous conditions in the oilfields of Ecuador. The Leyland Hippo chassis, with cab, is employed in each case, and tractor-type tyres are used. Winches and steel bodies of B. and E. manufacture are fitted.
These winches are operated from the gearbox of the vehicle. The power is transmitted through an auxiliary drive shaft and thence through duplex chain and sprocket drive to a B, and E. poweroperated two-speed forward and a single-speed reverse gearbox. The motive power then passes to a heavy-duty worm and worm-wheel assembly in a heavy-duty casing, the worm-wheel shaft running transversely across the vehicle and forming the main drum shaft. The main drum is securely keyed to the shaft and carries a .-in. steel cable, and an off-side secondary hauling bollard is fitted.
The body has dimensions of approximately 15 ft. 6 ins. by 8 ft., and is built throughout of heavy-duty rolled see,tions electrically welded and supported from the chassis frame members through the medium of heavy steel cast brackets. The floor is of i-in. steel
plate. Rollers are fitted to the front and rear ends of the body to prevent the rope from chafing on the front and rear edges of the body.
At the rear end of the body are two substantial brackets which carry the upper and front ends of two ramps manufactured from steel joists. These are used for loading heavy drilling and pumping mechanism from the ground level on to the floor of the body.
The ramps are made to pass on rollers underneath the 'body for stowage purposes and are, clamped down to the vehicle to prevent movement during transit.
