The Client was building a new paint hangar which required 550,000lb trusses to be set from a 20’ deep basement. Sicklesteel designed a proposal utilizing large cranes which would lift the main truss then convert to lifting jack trusses and building the next truss. Then, Sicklesteel provided in-depth layout designs and achieved manufacturer’s approval to utilize a DEMAG TC3200 (625 ton) to lift the main truss with its luffing jib attached. This approval eliminated any configuration conversion downtime and was a key for this project to be completed ahead of schedule and under budget.

The Client needed to remove, refurbish and reinstall overhead cranes weighing up to 120,000lbs inside of manufacturing building. Due to the limited clearance between the truss, roof and load, Sicklesteel selected to perform a multiple crane pick with two Demag AC615’s (250 ton) which had hydraulic booms capable of meeting the clearance restrictions. This solution reduced over one hundred man-hours per overhead crane from the previous method.

The Client needed to assemble whirly cranes with the maximum lift comprising of lifting the 436,000lb crane house, which was 45’ tall, on top of a 60’ pedestal. Sicklesteel proposed a multiple crane pick consisting of a DEMAG AC615 (250 ton), DEMAG AC435 (180 ton), and a KRUPP KMK6140 (165 ton). Lifts were completed on schedule and under budget.

The Client improved an existing unit necessitating the erection of 2 vessels with a 6-month delay between lifts. For the first lift, Sicklesteel proposed utilizing a DEMAG TC2000 with 157’ of main boom to lift the 286,000lb vessel out to a 45’ radius. For the second lift, Sicklesteel proposed utilizing a LTL-350 (transilift) with 220’ of main boom as the erection crane for the 424,000lb vessel as well as two (2) AC615’s to serve as tandem tail cranes to assist with rotating the vessel in the air from the horizontal to vertical position. Sicklesteel saved the client $300,000 of crane costs and completed the project 5 days ahead of schedule.

The Client needed to lift a vessel and complete the entire mobilization, lift and demobilization as quickly as possible. The only solution the client believed to be available was the installation of guy-derricks to make the lift. Sicklesteel utilized its AutoCAD system to provide an alternate proposal of positioning a DEMAG TC1200 (308 ton) in an area that contained clearances of less than 1’. Mobilization, lifting the vessel and demobilization were completed in less than 20 hours and well below budget.

The Client’s project involved placing numerous pre-manufactured modular sections to expand facility as well as many vessels with weights up to 200 tons. Sicklesteel proposed utilizing a DEMAG TC3200 (625 ton) with full superlift in order to accomplish the lifts. A key to the projects success was Sicklesteel’s design of a track assembly to transport the superlift counterweight on a self-contained framework and independent of the crane. This allowed the counterweight to be moved into position after the crane was set-up thereby maximizing the on-hook utilization of the DEMAG TC3200. The project was completed ahead of schedule and substantially under budget constraints.
