Bar Tensioner

Hightorque accepted the total task and supplied hydraulic jacks and pumps with safety and functional controls, very specific to handle this job. I-beam was suspended at two points from the trolleys over the launching truss. On each trolley 2 Nos. of 150T 300mm stroke jacks with single power pack were connected. Using pin lock method, all beams were lift, held, traversed, lowered and positioned right to the point with precision.

Entire work was executed with high safety level. In total of about 85 beams were positioned.
