Multiple car-parking equipment

摘要

The platforms (1A-C) are hoisted and lowered in the vertical directions between upper and lower levels. Positioning systems, which can be released, prevent hoisting and lowering, which is done by a hoist mechanism (3,5,6) with a motor-driven winch and suspension ropes reeved round pulleys in stationary mountings and on the platforms, bringing the latter into line with the exit.
