Case Studies

Major New England steel service center chooses Mass Crane for bay expansion

When a major New England steel service center needed two large cranes for a new outdoor crane bay, and needed them delivered and installed in 5 months or less, they turned to Mass Crane and its sister company, Connecticut Crane.

The Challenge

Mass Crane and Hoist fabricates its own box girders in its 20,000 sq-ft fabrication facility in Tyngsboro MA.
These girders were 2 foot wide by 5 foot tall by 105 foot long and take approximately two weeks per girder to build.
The girders alone would take 2 months to fabricate, and occupy the majority of Mass Crane's shop.
Component lead times were 8-12 weeks ARO, giving Mass Crane only 2 months to build, paint, wire, test, and install both cranes.

The Solution

Through multi-phase coordination and overlap scheduling, fabrication on the first girder began a short 8 weeks after receipt of the order. Mass Crane leased auxiliary fabrication space and moved its previously scheduled fabrication work off-site for the duration of the job. Crane #1 was delivered and installed 15 weeks after the order date. Crane #2 was delivered and installed 19 weeks after the order date, days before the deadline. The two cranes are currently in service at the steel service center and a valuable addition to their fleet.
