The type of prestressing steel wire tension machine is designed to make the prestress of steel wires for the medium and small-sized precast concrete components. It is composed of four main parts: winch, spring force measurement device, electric power control device, and wires fixture. The tension machine can work for the prestressing on the steel wires or bars sizes from ø2-ø6. It has many benefits and features such as lightweight, convenient moving, exact force measure, simply operating maintenance.And the he values of pretressing fore can be preset and controlled by the spring loaded.
Working Princle and process of the steel bar tensioning machine
The winch is composed of three main parts: electric motor, speed changing box and winding drum. Primary speed changing box is worm and gear; Last stage is pinion. The spring force measurement device is marked with force measurement weight which have calibrate in advance. Make the indicating arrow in the tensioning machine aimed at the scale value. Run the motor and magnetism mass touch the route switch when reaches the scheduled tension force. Power off automatically realize the tension force control automatically.The fixture is fixed with fall block, so the force of measuring meter is half of marked tension force. The clamp adopts crescent form which is reliable and easy to use.
