Alatas Americas recently performed Demag hoist gearbox repairs applying their extensive knowledge on various gearboxes in their Houston workshop. Due to leakage, the client initially sent this hoist gearbox for a Demag AC650 all terrain mobile crane to another crane service vendor. But as the vendor could not disassemble the unit, the client turned to Alatas Americas to repair the Demag AC650 hoist gearbox.
Our Workshop Repairs Solution
Alatas Americas performed a free disassembly and inspection to inform a comprehensive report of the leaky Demag AC650 hoist gearbox to begin the work, along with the cost of the proposed repairs. Once the client agreed, the Houston workshop got to work.
As standard with all work such as these Demag hoist gearbox repairs, the workshop replaced all bearings and seals as they’re considered a wear item. Next, a new preload bearing nut was manufactured in the workshop, and all new bearings and seals were replaced before the hoist gearbox was fully reassembled.
The Alatas engineers then pressure tested the Demag unit to check that all leaks had been rectified. The hoisting gearbox was left to run for a set amount of time before painting and packing the unit, ready to be sent back to the customer.
To complete the Demag hoist gearbox repairs, the Alatas team completed the required reports and paperwork, which was shipped with the unit back to the customer, including a 1-year warranty.
