Hitachi Hoists – In the middle of 2006, Hitachi Transport System, LTD. contracted Lampson International, LLC to remanufacture the two and three drum hoist systems and control cabin for their LTL-2000. The hoists had been working steadily since they were originally manufactured by AMHoist/Conmaco in 1983, and were in need of a major overhaul.
Upon arrival of the hoists and cab, Lampson personnel disassembled, inspected & evaluated every component on the two hoists. Based upon the results of those evaluations, the components were cleaned, machined, resurfaced, rebuilt, repaired, or replaced. After reworking the components, the hoists were re-assembled and load tested to exceed the service loads they have seen or will see or future service.
From machinists and mechanics to quality assurance and engineering, the skills and craftsmanship of nearly all Lampson departments were utilized to successfully complete this project. Lampson’s unique and impressive facilities provided the necessary means to carry this project to completion.
Taking six months from receipt to release, this project demonstrates the capabilities of Lampson personnel and resources to perform fabrication and manufacturing duties in a timely fashion.
Colorado Energy – For the past year, Lampson International has been working with Colorado Energy Management on a large relocation project. The project has focused on disassembly of power plant components, transportation, and construction of a new plant. The project has encompassed two plants, three states, and numerous sub contractors and railroad companies. The project is on schedule and due for completion in 2008.
Wind Farm Projects – Over the past five years, Lampson International has become more and more involved in the wind power industry. With large facilities in both Washington and Colorado, Lampson has been able to provide a service to power corporations that other companies have not. That service is the storage of wind tower components through the provision of a lay down facility. In addition to providing this service, Lampson has also engaged in the heavy hauling of these components, as well as construction of the towers themselves. Finally, Lampson also provides crane rental service to companies looking to bare lease our equipment.
Sunoco – The Sunoco Project in Philadelphia was unique in that it required a crane with extraordinary capacity, reach and mobility and was required to move some components through 180° of swing. The LTL-2600, fitted with 420' of main boom and a 15' offset Jiblet, met those requirements. The replacement components were coming in via river barge and the Transi-Lift had to lift them off the barge and place them in the Jig Stand area for build-up. In the mean time Goggle Valves and other components weighing some 50,000# to 75,000#, had to be set at a 387' radius.
Following completion of the build-up of the Reactor Head and the Regenerator head the old Reactor Head was lifted out and placed in its Jig Stand and the new Reactor set into place. The Old Regenerator Head was removed and set in its Jig Stand and the new regenerator Head was lifted and set into place. The Regen Head produced a total lifted load of 850 tons which was set at a radius of 250'. The Transi-Lift LTL-2600 performed flawlessly during the 7/24's Turnaround with zero downtime. In addition, Lampson received a Safety Award for zero safety incidents and no lost time during the entire project which lasted some 7 months.
Catlettsburg – At the Catlettsburg refinery, the unit is built on a plateau that is bounded by a pipe rack to the east and high voltage power lines to the west. On the south edge of the unit was a precipice dropping down to a lower plateau 50’ below. The north boundary of the work area was a vertical structure 62’ above grade. The crane would need to reach over that face to the Regenerator 175’ north. The total length of the crane could not exceed 440’ (during erection) and that length would require cantilevering the boom tip taper and boom tip weldment over the east pipe rack to install those sections.
The 600 ton Regenerator Head lift required a Lampson 2600 Transi-Lift with 5200k of counterweight to achieve the client’s requirement for an 85% of capacity lift at that radius. To achieve our goal of safe and successful lift, over 50 drawings, critical lift studies, and geotechnical and unit demo plans were developed in the 2 months prior to site mobilization. It was incredible that so much was accomplished in so short a time since most of our major heavy lift projects are bid at least a year ahead of mobilization and lead times in our current market suggest that two year planning times are not unusual to accommodate the engineering and logistics involved.
Although the lifts at the refinery were straight forward, the erection procedure was challenging. Lampson personnel squeezed every inch out of the erection area and worked the support cranes to their limits. Cranes involved in making these lifts included a Manitowoc 4100W with Series 3 Ring required for mast erection in narrow area, Manitowoc 888 S-2 required for the boom tip weldment lift over the pipe rack, and a Manitowoc 4100W S-2 which was required to tail the strut. To finish erection of the boom, a stack of four Transi-Lift ® counterweight boxes were used as cribbing to block the boom 16’ in the air over a major electrical substation and cantilevered over the east pipe rack.
When the project was complete, our clients were very complimentary of both our extraordinary efforts in completing the project and the professionalism our personnel dispelled.
Bechtel Spreader Bar - In February 2005 Bechtel National Inc. awarded Lampson International LLC the contract to design and construct an adjustable lifting fixture to lift and set 18 piping modules for the WTP Pretreatment Building. The modules range in weight from 54,000 pounds to 339,000 pounds with each having a unique lift point arrangement and unsymmetrical center of gravity location. To prevent unwanted stress in the piping module a maximum deflection criterion of the Length (inches) divided by 300 was also specified.
The Lampson design team, led by senior rigging engineer John Allen and professional engineer Ryan Hoff, designed a modular rectangular beam system that is fully adjustable to within an inch in both directions and can be hydraulically adjusted to account for the offsets in the center of gravity. Using hand calculations, computer aided design, and finite element analysis the engineering team invested 4000 man hours to ensure the design met the strict requirements of the contract.
Lampson then worked closely with BNI engineers to refine existing welding procedures and construction methods to guarantee the completed components could withstand the rigors of everyday use on the construction site. With machine tolerances of thousandths of inches Lampson Ironworkers and Machinists, led by Mark Sanders and Bob Burke, completed the 100,000 pound steel fabrication in July 2007 investing approximately 10,000 man hours of quality workmanship.
The acceptance and testing phase of the project began August 1, 2007 with the lifting fixture being assembled in a configuration that would induce the worst case loading in each of the components. The final load test of 125% of the worst case load proved the integrity of the entire system.
On completion of the test, the lift fixture was disassembled, sand blasted, painted and re-assembled in the proper configuration for the first lift at WTP and delivered. Lampson will continue to work with BNI to provide specific rigging arrangements and technical support for each module lift as it is performed at WTP.
