Comer Industries Supplies Lampson for New Mega Crane 3000t

LTL-3000 Fabrication progress_lightLampson was searching for a company sharing the same values of integrity and quality to construct their next generation of hoists for their new mega crane LTL-3000 Transi-Lift: Comer Industries’ products for this application were selected from a wide portfolio of laboratory and field proven winch drives. A number of various winches with different drum diameter and pulling torque have been equipped with Comer IndustriesPGRF-25004 and PGRF-6503 drives, allowing Lampson engineers a comfortable level of flexibility in their machine design.

Safety and reliability are fundamental requirements: the drives have been tested at the Mechatronics Research Centre in Comer Industries Headquarters, simulating thefield function under severe duty cycle. Specific calculation tools have been implemented and verified on the field, aiming at the correct sizing of the drive, granting safety standards are achieved. According to EFQM methodologies, Comer Industries’ components are classified with regards to failure and level of safety. An internalmetallurgic laboratory analyses individual key gearbox components to guarantee their mechanical and chemical properties, and ultimately the safety of the crane itself.

To develop its new crane, Lampson chose Comer Industries hydraulic winch gearboxes. Main hoist lifts are made using eight 270 kNm capacity gearboxes. Smaller capacity drives power the whip and auxiliary hoists. Specifically, two PGRF- 25004 per drum have been  assembled on the four winches, each one capable of 52 T line pull, used on the main hoist function. The same drive has been used  in a single unit for the whip hoist. Two PGRF-6503 units  have been selected to rotate the drum of the auxiliary drives.

The project was supported by the company’s North American subsidiaryComer Industries, Inc., located in Charlotte, NC.  

In November 2013 the Lampson International LLC mega crane LTL-3000 Transi-Lift successfully completed its final tests before delivery to a major manufacturer of nuclear power plants. With 3,000 tons lifting capacity, the LTL-3000 is one of the premier heavy lift cranes in the world.  Randy Stemp, Engineering Projects Manager at Lampson, was quoted, “Comer Industries sales team has been prompt and knowledgeable, their engineering support has been invaluable to development of our systems, their delivery has been as promised, and their pricing fair and reasonable.”

Applications include power plant construction as well as oil and gas sites. The crane is fully mobile with individually powered crawler transporters. The Transi-Lift system is apatented configuration that combines the heavy lifting capability of stiffleg derricks and ring-mounted lift equipment with the mobility of a conventional crawler crane.
