Page 11: Working Conditions
WORKING CONDITIONS The hydraulic turning device, or rotator, is designed for use on a hydraulically-powered lifting crane, e.g. cranes that handle timber or single items. The rotator axle is fitted to lifting equipment, e.g. a grapple, which grips the load. The load can be rotated horizontally using the rotator. -
Page 12: Service And Maintenance Instructions
OPERATING INSTRUCTIONS Exercise caution when using the crane and rotator and act in accordance with the crane's safety instructions. Lateral loads on the rotator axle should be avoided. For example, prior to lifting, loads must not be pulled using the crane or the crane's base vehicle. A broken hose or nipple can cause the load to fall or rotational movement to continue. - Page 13 EXPLODED DIAGRAM: ROTATOR Designation Quantity Bolt Lower bearing housing Axle seal Seal Bearing O-ring Axle diam. 40 Spring Wing Seal Plug Spacer Plug Upper housing Table of Contents...
