Depression securing for hand-operated hydraulic lifting device with lifting aggregate

摘要

The depression securing has a lifting section (10) for hydraulic elevation of a height-adjustable chassis (2) of the lifting device, and a pump section (19) with, in a pump cylinder (15), a pump piston (13) for supply of hydraulic medium to the lifting section. There is a connected shaft (3) via a shaft rotation axle (30) linked with a lifting aggregate (1), whereby the pump piston (13) is operable via movements of the shaft. There is a movably arranged movement section (4), having a support organ (41), linked to the shaft rotation axle.
