Ram operated construction material skip hoist - has linkage moving strip slider for over twice ram working distance

摘要

The hoist mechanism with a skip particularly has a slider with skip moved up and down vertical or inclined guide rails by a hydraulic ram with mechanical transmission to the slider. A linkage (12-17) transmission is so designed that the distance over which the ram (10) works is less than half that travelled by the slider (2). The linkage includes a front lever (13) coupled between the slider and ram, and a rear one (16) coupled between the front lever and the frame (1). USE/ADVANTAGE - For mobile concrete mixer plants etc, with improved safety and operating reliability.
