Self erecting gantries
The B-Set series, is basically a self-erecting-tower-lift system, that enables you to build a free standing gantry from ground level, that can be erected up to a height of 80 meters and with a lifting capacity up to 2400m ton. Lifting and Skidding is executed by using standard Hydrospex Strandjacks. The B-set can be supplied in various capacities and heights, but they are all build with standard components, this enables you to upgrade your system into a larger system in the future.
** The Specialized Carriers & Rigging Association (SC&RA) has nominated the BSET project to become job of the year in 2009!
Fields of operation
The B-Set is a versatile lift-system that can be used in a wide variety of operations, like erecting of reactor vessels on petrochemical plants or lifting of shipyard cranes. If compared to big ringer-cranes, the B-set can outperform them on mobilization-time and transportation costs. The B-SET1250 (1200ton capacity on 50 meters height) can be shipped in 28 container loads anywhere in the world.
Self Erection
One of the unique features on the design is the patented design of the self-erecting-mast system. At ground level there are 2 lift-containers per mast. On the inside of each container there is a hydraulic mechanism, which lift the mast barrels in steps of 300mm per stroke. The mast barrels have an octagon shape. They are made from S690Q steel and welded with robot technology to obtain perfect quality to strength and dimensions.
Bracing System
To obtain stability in the mast, we make use of a sophisticated bracing system. Once the barrels are extracted above the lift container level, adjustable bracings are installed by hand. To reduce weight the bracings are made from high-grade steel.
Skidding System
The gantry is commissioned on skidtracks that also reduces the foot-print-load. Strandjacks are used to pull the gantry system in the desired direction.
Lifting
To lift the load, the B-Set makes use of Hydrospex Strandjacks with a capacity of 650m Ton each. Depending on the B-set configuration, 2 or 4 Strandjacks are used. Side-shifting the load can be achieved by a skid-system that is operated from the Strandjack powerpacks.
Operating system
To have the B-Set under control, we make use of two advanced PC-Control systems.
The primary system is used to lift all individual mast corners within an accuracy of 3mm between all corners. It automatically lifts the towers with an average speed of 3 meters per hour. The secondary system is our proven SCC control system to operate all Strandjacks. All powerpacks and control-systems are powered from a 100kW generator.
Configurations
The B-Set system offers solutions for heavy lifting jobs in the range of 50-80 meters high and loads up to 2400mTon. Which type of B-Set suites you best can be found at the upper left side of this page, where you will found our range of lifts. Please contact us when you have special requirements.
