A Lifting Gear and its matched Retractable Container The lifting gear consists of 3 systems (Figure 1): 1. 1st Axle System: 1st-axle, 1st-balancer, base board, on the 1st-axle there is a direction-controlling ratchet wheel and a set of (totally 6) 1st-fixed-pulleys. 2. 2nd Axle System: a 2nd-axle, a 2nd-balancer, a clutch within and a 2nd stepping gear of 2nd -balancer-lifting. On the 2nd-axle, a pair of 2nd-fixed-pulleys, 2nd -chains/ropes with the 2nd-balancer on one end and a plummet on the other end. The 2nd stepping gear for pulling the 2nd-balancer, includes a driven wheel attached to a 2nd-axle, a small driving wheel, a large driving wheel, a 1st-gliding bar, pressure lever and a 2nd direction-controlling ratchet wheel. 3. 1st Applying System of Auxiliary Lifting for lifting the base board: a fly wheel on 1st-axle, a 1st-gliding-bar, a pressing-surface (pedal). The retractable container is for a special usage of the device, namely, the retractable wheelie bin (Figure 12). |
