REMOVING THE OLD GEARBOX

A custom rig with a massive I-beam and a beam trolley was required to safely lift the gearbox. The hydraulic gantry crane's I-beam is rigidly supported by a 100 ton capacity hydraulic ram on each end.





The gearbox is secured to the crane and ready to lift.











Moved to the shop floor away from the moving cables on a 50,000 lb. capacity transport cart.





A coupling being removed from the worn unit to be reused on the newly refurbished gearbox.
