Lifting trolley which clamps and raises barrels automatically - has front main forks with two wheels and trailing castor with vertical chassis member carrying mast with extension and front pinch clamp

摘要

The trolley chassis has front main forks (4) with two wheels (6) and a trailing castor (9). A vertical chassis member (2), in front of the castor, carries a mast (1), with extension (19) and front pinch clamp (21) for the barrel (30). A parallelogram pivot (7) for the castor has a diagonal compression spring (18) inclining the mast forward towards the barrel, when unloaded. Once the barrel top rim is clamped, the load acts against the spring to bring the mast vertical, lifting the barrel from the ground. The barrel inside top rim is less than its major diameter. ADVANTAGE - Simple, easy use, safe and automatic lifting, to transport barrels vertically, for immediate stacking.
