Hydraulic nuts for upper loads can be set to a precise preload with an accuracy of up to 3% earth; they can be supplied with a stroke indicator that allows the amount of tension to be observed, measured and controlled during operation.

SL-HN series top load hydraulic nuts are especially suitable for tightening in narrow spaces and heavy duty vibrating machinery, and can be assembled with several bolts at the same time. The torque-free design avoids friction, bolt twisting and other factors affecting bolt preload, and the tightened bolt is subjected to pure tensile force.

SL-FSM flange splitter

Suitable for pipe maintenance, repair, testing and flange replacement applications, frictional, parallel, smooth movement, will not cause flange damage wedge size is only 6mm, mechanical, hydraulic two options.

SL-TM On-rail heavy load transfer machine

SL-TM Railway Track Heavy Object Pusher

The on-rail weight pushing machine (referred to as the moving machine) is composed of two parts of the clamp and the moving cylinder, which has been widely used in the country’s large transportation industry, and is equipped with the corresponding ultra-high pressure electric oil pump station and auxiliary devices for moving operations. Users need to bring their own heavy rail (38kg/m, 43kg/m,50kg/m) and active and passive boots. In order for the weight to be moved to run smoothly, two sets of push machines must be used at the same time.
At present, it has been widely used in the national heavy load transportation industry.
