Strandjack Gantries - Strand jack gantry
As a logical next step, in 2008 Hydrospex introduced the strand jack gantry into the market. The strand jack gantry is more then just a steel structure to facilitate strand jacks. It enables heavy loads up to 500 metric ton to be lifted, the load to be skidded inside a building and afterwards dropped and installed on the spot.Modular and flexible system
The system has been engineered in such a way that it can be utilized in nearly every situation, when it comes to installation of boiler drums, generators, turbines, etc.
The lower columns of the gantry are build from segments of 1 meter each. These columns are equipped with a hydraulic driven spindle, enabling the skid beams on top of the columns to be perfectly aligned with the beams inside the building. The upper columns are modular and consist among others of units of 50 and 25 cm. This enables the top side of the structure to be height adjustable as well. Since the system is modular, it is easy to expand your scope in the future.
Hoisting
The complete structure has been engineered to hoist loads up to 500 metric ton. The header beam on top facilitates a rigid frame in which a strand jack, strand guide and power pack can be installed. This enables lifting up loads to 20 meters. Height adjustments can be engineered upon demand.
Skidding
On top of the skid beams, the upper columns are connected to our HSK120 skidding system, enabling the top structure to be skidded back and forth. All is being operated at the powerpack on ground level. Skidding is easy to operate and movement is boundless.
