Elevation device is moved by lift devie with operation of wheel with movement in opposite direction to lowermost position when wheel is no longer operated

摘要

The elevation device is used in fairground equipment and its lift equipment is wheel-operated. When the fairground equipment is moved in the opposite direction to its lowermost position, this occurs when the wheel is no longer used. This makes possible a simpler and safer use of the equipment. Two or more lifting devices can be used mutually competitively.
