Four Grove all-terrain cranes worked seamlessly to assemble a large container crane at a port in London. The cranes are all owned by U.K.-based J&M Crane & Transport, which provided full lift planning and engineering for the complex harborside installation.

The cranes selected for the project were: GMK6300L-1, GMK5250XL-1, GMK5250L and GMK5150L. Each was precisely configured for the lifting work, with boom lengths set between 90.8 ft. and 109.9 ft., and counterweight, rigging, outrigger spread, and other details matched to the requirements of the lift. The engineered lift lasted 12 hours, capping a successful six-week container crane installation for J&M Crane & Transport.

"This project was all about detail, delivery and reliability," said Ben Lawrence, sales director and CPCS appointed person of J&M Crane & Transport. "We selected the four Grove cranes for this lift because we knew they offered the strength and reassurance we needed. We used our in-house J&M CAD Blocks for lift planning and after many weeks of installation and set-up, it was fantastic to see the four cranes install the 199 t [219.36 tons] upperworks on the legs of the container crane."

The GMK6300L-1 is a six-axle crane with a 330.7-ton capacity and 262.5-ft. main boom. The other cranes on the project are all five-axle models with capacities of between 165.3 tons and 275.5 tons. J&M Crane & Transport purchased the cranes directly from Manitowoc U.K.'s office, which also provides full customer support including parts, service, training and technical assistance from its facilities in Buckingham and Barnsley.

J&M Crane & Transport is a family-owned company providing crane rental, engineered lifting, transport, abnormal load movement and more to customers across the U.K., with a focus on the south of England. The company has been in business since the 1950s.
