Inclined lift with several telescopic elements - has pressurised line for ancillary hydraulic ram coupled to hydraulic brake

摘要

The lift consists of several telescopic elements and at least one main hydraulic ram, which is used to adjust the angular position of the telescopic parts w.r.t. a common base. A hydraulically operated brake is used to fix the angular position of the telescopic parts. It is released by applying hydraulic pressure, and is actuated by the pressure drops. Two telescopic parts (1,2) are incorporated, whose angular relative positions can be adjusted. A secondary hydraulic ram (6) is located between the two telescopic parts. A pressure line (8) for the secondary ram is coupled to the brake. The ram adjusts the telescopic parts when pressure is applied to it so that they are aligned. USE/ADVANTAGE - For roof material transport etc. with simple control and reliable operation.
