Overview Of Hydraulic Steel Wire Tension Machine
The hydraulic prestressing tension machine for prestressing is composed of tensioning jacks, electric hydraulic pumps, high-pressure hoses, anchors, etc. According to pretensioned prestressing method, this machine is mainly used for tensioning steel wires, steel strands for the making bigger medium-sized prefabricated components such as precast hollow core slabs,wall panels,beams,columns etc.
Prestress tension machine is a kind of equipment specially used for prestressed structure construction, which is widely used in the tensioning construction of prestressed steel bars and steel strands in bridges, buildings, tunnels, dams and other fields. It uses the hydraulic principle to convert the energy of high-pressure oil into mechanical force to complete the stretching of prestressed tendons to meet the prestressing requirements of the design.
Features and Benefits
The hydraulic prestressing tension machine is compact in structure, easy to use, light in weight, easy to move, and easy to operate. The ultra-high pressure main engine pump station is designed for high and low pressure two-stage design, and the stroke speed of the press clamp is adjustable, which can be flexibly used in various complex environments.

Principle Of The Steel Bar Tension Machine
Hydraulic system Includes hydraulic pump station, oil cylinder, pressure gauge, control valve, etc. The hydraulic pump station provides high-pressure oil as a power source and adjusts the tension force through the control valve. Tensioning jack The jack is the core component of the hydraulic tensioning machine and is used to directly apply tension. According to the type, it can be divided into single-acting jacks and double-acting jacks. Anchors and clamps Used to fix prestressed tendons and transmit tension force to ensure that the steel bars or steel strands do not slide during the tensioning process. Control system Monitor and adjust the tension force electronically or manually to ensure precise operation. Auxiliary equipment Such as tensioning platforms, workbenches, brackets, etc., used to support and fix equipment and workpieces.
We have few types of steel wire tension machines, which can meet the work needs of customers at different sizes bars strands usage,




Operational Process of Tension Machine
During operation, one end of the steel bar/wires is anchored, and the other end is tensioned by the tensioner through the clamp. When the feed-through tensioner is working, the steel bar is penetrated,the front oil nozzle is opened, and the high pressure oil is sent into the rear oil nozzle by the hydraulic pump, so that the tension cylinder is retreated, and the steel bar is anchored and tensioned by the tail anchorage.
After tensioning to the desired stress value, close the rear grease nipple. The front oil nozzle enters the oil, the piston pushes forward, and the anchor plug is pressed to anchor the steel bar. When returning, the piston is reset by the spring to complete the tension.-Hydraulic Steel Wire Tension Machine
