The Client needed to replace a C.O. boiler which was in an area with limited access. The standard approach was a six-week process which included tearing the boiler down in pieces, replacing the tubes and then rebuilding the boiler. Instead, in conjunction with the contractor, Sicklesteel devised a plan to fabricate a new 179 ton boiler off-site, roll it to a DEMAG TC3200 (625 ton) crane, pick the old boiler out at a 110’ radius, set it off to one side and then swing the crane around and set the new boiler in. This plan reduced the change out of the boiler down to under 10 days, saving the client considerable oil to oil time.

The Client had a limited access area with minimal clearance to lift heat exchangers during a plant turnaround. Sicklesteel proposed utilization of a DEMAG TC1200 (308 ton) to lift exchangers, weighing over 100,000lbs, at a 79’ radius.

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 79 ton Yankee Drier off of barge and install it on the 2nd floor through an opening in the side of the building. Sicklesteel proposed utilizing a DEMAG TC1200 (308 ton) which would lift the drier to the opening and also designed a mid-air transfer of the load from the DEMAG TC1200 to an overhead crane stationed within the building.

The Client needed to replace a convection box at the top of a vessel during the middle of a turnaround. Sicklesteel proposed utilizing a MANITIWOC 4100 Ringer positioned within the unit so as not to block a main roadway of the plant. Sicklesteel also assisted in the design of spreader bars in order to accommodate the limited lifting clearances. Project was finished ahead of schedule and under budget.

The plant needed to replace air heater in a recovery boiler but did not have adequate room to position a large crane for the required lifts. Sicklesteel utilized the AutoCAD system to select a large crane which would meet the clearance restrictions as well as perform the work economically. The project was completed ahead of schedule and under budget.

The Client needed to lift piping within plant. Lift required reaching 60’ in from an obstruction 140’ in the air. Sicklesteel proposed utilizing a KRUPP 140GMT-AT with 146’ of main boom and 80’ of luffing jib. Project was completed ahead of schedule and within budget constraints.

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.

The Client needed to erect a pressure vessel in a restrictive area. Sicklesteel proposed utilizing a smaller crane in an alleyway instead of a ringer sitting on the outside of the unit. Sicklesteel utilized CAD to demonstrate the lift and portray the critical clearances. Sicklesteel performed the lift with a KRUPP 140GMT-AT (165 ton) saving the client considerable time and nearly $100,000 in crane costs.

Sicklesteel Cranes Utilized CAD to design assembly of a DEMAG TC1200 (308 ton) configured with 177’ main and 118’ of jib. Site required boom to be erected between railroad tunnel and pipe rack (120’ apart). Sicklesteel Cranes initially positioned crane in railroad tunnel and utilized 3 other cranes for assembling boom in the air. Site required passage of rail cars through tunnel in 12 hour increments and also had uneven ground coming off of railroad grade. Sicklesteel completed the project ahead of schedule and under budget.
