Prestressing jack is one of the indispensable and important tools in the tension anchorage construction of Prestressing bridge project. No Prestressing jack of any kind is a panacea. Prestressing jack structure, structure size and tension tonnage limit its range of use. Prestressing Mono jack is a kind of multi-purpose prestressed tension equipment. Prestressing Mono jack is mainly used for single-hole tensioning, and can also be used for porous prestressing, tensioning and drainage. Prestressing Mono jack is suitable for a variety of specifications and sizes of high-strength steel wire and steel strand.

Structure and principle of action
The front clamping jack adopts the structural form of "static piston and moving cylinder body". When prestressing is applied, the piston and tension weighing sleeve of the jack remain stationary, while the outer cylinder liner, core sleeve, tool anchor and other components move backward relative to the piston. Tool anchors and tool clips hold the strand in this process and stretch it. When the required prestress value is reached, through the oil return operation, the outer cylinder liner, the core sleeve and other components are reset, while the working clip and the working anchor are automatically anchored, so as to complete the whole tensioning process
