Abstract
Tipping elevator-hopper feeding constituents into concrete mixer has counter pulley engaging traction cable during late descent thereby dissipating hopper momentum and effecting brakage. Permits rapid travel with high rise. A ramp is lightly inclined(3) and then angles steeply upwards(2) and has twin parallel rails carrying a four wheeled hopper(7) from loading to tipping stations; traction being effected via a cable following ramps in elevation and describing a U in plan, terminating in head located anchorage and winding drum(12) and traversing the hopper belly via flank pulley wheels. A frame mounted counter pulley(13) located at the top of the lower ramp(3) carries the cable traversing the hopper belly, thus breaking the descent whilst winch drive remains constant.
