Lift height limiter lifting device load-lifting machines

摘要

The invention relates to hoisting and transport technic. Lift height limiter lifting device lifting machine comprises: a load-bearing structure, hinged on the bearing structure lifting machine; inductive proximity limit switches to control the drive with the lifting device the control member in the form of articulated angular two-armed lever of conductive material to the first arm which is suspended on a flexible member controlling load cooperating with the lifting devices, and a second arm located opposite said circuit breaker; an elastic member cooperating with the second arm of the angular double-arm lever and arranged in a vertically fixed flat spring of electrically conducting material; and limiting movement of the first arm angle lever under the control of the cargo. Power structure is formed as a vertically extending control panel includes its own panel to form a flat elongate rings of sheet material on which the switch angular double-arm lever and the elastic member. The control panel is provided with a removable cover with a sealing gasket. On the front surface of the cover wall adjacent the clevis, the longitudinal slot is formed, through which the omitted first arm angle lever and movement limiter of the first arm of the angular lever is the lower edge earrings. The technical result - increasing the operational reliability of the limiter. 2 ZP f ly-5-yl.
