A NEW hydraulic overhead loader is being manufactured by F. E. Weatherill, Ltd, Union Row, London, N.I7. It can shift 100 tons an hour and is intended to be complementary to the Weatherill front-end loading phovel. The equipment is built on a standard Fordson industrial tractor, fitted with a 44 b.h.p. four-cylindered oil engine, and hydraulic power is supplied by a Vickers vane-type pump driven from the engine crankshaft.
Structurally, the Overloader consists of a bucket scoop pivotally attached to the ends of a pair of fabricated side arms which, in turn, are pivoted to the main frame of the tractor. The arms are raised and lowered by two main hydraulic rams, and when they near the end of their rearward travel a pair of secondary rams completes the overlead movement of the scoop. The speed of the side arms s decreased just before discharge, thus assisting in complete mmtying of the scoop.
A further pair of rams is mounted on the side arms to vovide a crowding action to the scoop when filling. At no ime do the arms actually pass the driving position, which is urther protected by an overhead shield. The loader is vailable with either a 1-cu.-yd. or 1-cu.-yd. scoop, which nay be supplied with digger teeth. A single operating lever ontrols the operation of loading and discharging, the rate .cing up to four cycles per minute.
