Overhead crane project
Linian Crane and Hoist Company has designed a bespoke lifting system for a sizable metal treatment facility for Knowsley Engineering Services for one of its clients.
The facility comprised a number of dipping tanks in a line 30 metres long. The crane system lifts a large cage containing production items from the floor to a height that just clears the tanks and travels, lowering the cages into tanks as needed.
The crane also recovers and relocates the cage after treatment. The system had to work around very limited headroom and tight space around the treatment tanks.
The free standing gantry system has two five tonne cranes. Headroom was very tight so special twin hoist double girder cranes were designed with each crane having the twin electric chain hoists mounted in fixed positions and suspended from brackets above the double girders.
Purpose made lifting frames were designed to be suspended from the hoists and to easily locate on the lifting lugs of the cages manufactured by Knowsley Engineering.
