LIFT FOR AUTOMOTIVE VEHICLE Russian patent published in 1995 - IPC

FIELD: garage equipment; lifts. SUBSTANCE: lift has device to control travel of carriages with signalling arrangements indicating relatively safe positions of lift and vehicle under servicing. Lifting mechanisms screw rotation converters have impellers secured on screws and slot-type inductive converters also secured on screws. Signalling arrangements indicating safe positions of lift and vehicle are coupled, together with lifting mechanisms motion converters, with microprocessor program setting unit by means of functional coupling. Setting of synchronous lifting basing on correlation of motion of lifting mechanisms with position of vehicle relative to lift provides higher accuracy of synchronization in time, fixed electric coupling of lifting mechanisms motion converters with control and automation of operation. EFFECT: enhanced operation reliability. 8 dwg
