DISCRIPTION :
Hydraulically operated gun type pre-stressing unit is designed for pre-stressing of carbon or glass gilled nylon resin fibers while strengthening of damaged concrete structures like beams, slabs etc. The same for pres-stressing on silos / columns is also available.

It is operated on 3 phase AC power supply without need for neutral wire. The electric motor driven radial piston pump provides oil flow at high pressure for required stressing force. The guns can be operated by simple pressing of push buttons on trolley which is on floor.

When pre-set stressing force or Stroke as selected and set is achieved, pilot lamp glows and solenoid valve is stopped automatically. The gun will remain in stressed position until retracted by second push button by operator.

The stressing pressure can be set on pressure control valves provided on operator console. The stressing can be read in terms of bar on a gauge and kN on digital meter. The whole unit is mounted on wheels and castors for easy movement.
