Abstract

845,691. Garage lifts. LAYCOCK ENGINEERING Ltd. April 14, 1959 [July 7, 1958], No. 21631/58. Class 78 (3). Each platform raising nut 16 of the garage lift described in Specification 845,692 is provided with a device comprising a switch 23 which open-circuits the or each chain driving motor when, due to the platform 11 meeting an obstruction during lowering, the nut is driven downwardly relative to the platform, thereby causing a disc 21 to engage a switch-actuating lever 22.
