Rebuilding begins with sandblasting to help our staff identify any failures or fatigued areas. These are then restored or replaced. Worn bucket lips and grapple teeth are replaced with abrasion resistant steel.
All pins and bushings are inspected for wear and if needed replaced with Mack top quality components designed for long service. Sheaves are inspected for wear and bearing condition. Rope grooves are re-worked and bearings replaced. Hydraulic systems are completely disassembled and cleaned. Defective pumps and valves are replaced with top quality components. Cylinders are rebuilt to our exacting specifications.
Finally, your unit is assembled, tested, and painted. The finished product is renewed and ready for long service.
Here at Mack Mfg. we have a long history of being innovators of design. This happens because we take the time to listen to our customers.

Mack Mfg. has been a leader in the crane attachment industry in a number of areas. One of these areas is the reconditioning of used attachments. It doesn't matter what name brand the attachment is; Mack Mfg. is the company you will want reconditioning it. Normally we are able to supply you a good estimate for repairs prior to you sending it to us. After we receive your grapple or clamshell bucket we completely disassemble it, closely inspect it, and then send you a complete list of repairs required and cost to place your unit as close to "like new" condition as possible. Contact us and see what we can do for you.
