LIFT & ROLL SYSTEM Rig 102, SINGAPORE 2001 back to top
This is an alternative lift & roll system supplied by Hilman Rollers for Rig 102. The cantilever beams are supported by six rollers—1,250 tons each. Each roller is supported by six hydraulic cylinders nested in a sub-frame. The hydraulics ensure that each roller is under full contact during the skidding mode. When retracted, the rig does not contact the rollers. No more freeze-ups! No more beam tear-ups! No more huge pushing cylinders!

Heavy Construction

CONCRETE BRIDGE CONSTRUCTION
San Antonio “Y”, San Antonio, Texas USA
1987
back to top

Mating concrete bridge segments for a highway overpass is made simple with the use of Hilman Rollers. The castings for the San Antonio “Y” were rolled into place on three Hilman Rollers, modified with Accu-Roll Guidance Systems and a special top that allows for lateral adjustability.

The San Antonio “Y” is part of an upgrade of two major Texas highways that meet in a “Y” formation in the central area of San Antonio. The upgrade involved the addition of six elevated lanes to the existing four lower lanes, for nearly a 10 mile stretch. The Hilman Roller system used to roll the precast segments into place, also has the ability to “rock” for precise alignment. This concrete bridge construction process worked so well here, that it has been used for constructing other USA bridges and bridges in other countries

Material Handling

JET ENGINE ASSEMBLY CARTS
Middletown, Connecticut
1993
back to top

Unique two piece carts have been in service at this manufacturing plant for over eight years, enabling aircraft engines of various sizes to ride through assembly. The cart halves, each with four low-height swivel style Hilman Rollers attached, ride on imbedded rail tracks. The system is not only high capacity, it is easy on the workers because the Rollerskeep the engines at a conveniently low working height.

Even though the production lines are straight, occasionally an engine must be removed from the line to be inspected or to allow a faster moving assembly to proceed through the line.The swivel tops of the Rollers facilitate this process: the carts can have their guidance system disengaged and the Rollers turned, allowing the engine under construction to be removed from the line.

Structural Moves

CAPE HATTERAS LIGHTHOUSE MOVE
Cape Hatteras, North Carolina, USA
1999
back to top

The historic and famous lighthouse that stood on the shores of the Atlantic Ocean and guided mariners to safety for more than 100 years was threatened to destruction by an encroaching sea.

The contractor had the task of engineering a way to move the 4,800 ton historic structure to a safer resting place and to one that would still maintain the landmark as an historical site for the National Park Service. The new site was located 2,900 feet from its current resting place and back 1,600 feet from the sea. The new site was also at a slightly higher elevation which meant the move would be slightly up hill.

It was decided to roll the lighthouse to its new resting place in order to preserve the structure and to eliminate substantial reconstruction costs. A total of 100 modified Hilman rollers, each with a capacity of 100 tons and equipped with Accu-Roll guidance, were used. In addition, the roller top plates were equipped with a ball socket plate to accept a hydraulic jack which was part of the unified jacking system.

The rollers traveled on steel I-beams and carried a support assembly consisting of twin I-beams. The twin I-beams were parallel to the travel beams and on top of them were cross beams which carried the lighthouse base. Hydraulic ams anchored to the travel beams pushed against the twin I-beams provided motive force for the move.

Marine & Shipbuilding

SHIP LAUNCH
Atlantic Eagle Workboat, Nova Scotia, CANADA
1999
back to top

The Atlantic Eagle workboat rolls down the gangways on Hilman rollers at the shipyard. Several 150 ton capacity “OT” style Hilman rollers modified with Accu-Roll “R” were used to launch this new workboat. The launching rails ran from the ways into the water and provided the rolling surface for the guided rollers carrying the vessel. After the launch, the rollers are retrieved, washed-down and will be used for the next launch. Several shipyards now use Hilman rollers for launching vessels ranging from small workboats to large ocean going ships.

STEPUP TRANSFORMERS IINSTALLED
Sylmar, California USA
1986
back to top

Hilman 150-ton capacity modified Rollers were used to move several transformers in this job for the Department of Water and
Power in Sylmar, CA. The Hilman Rollers, which were bolted to the transformer bases, were modified to ride in channel with an
Accu-Roll guidance system.
