Prestressed Bridge Tension Equipment Hydraulic Mono Strand Jack
Description of Hydraulic Mono Strand Jack
Hydraulic Mono Jack is multi-purpose prestressed tension equipment, easy to operate. Mainly used for single-hole tension. It can also be used for porous pretension, tension, and barrier removal, and can be applied to a variety of specifications and sizes of high-strength steel wire bundles and strands. Jack is one of the indispensable tools in tension anchorage construction of prestressed engineering. No jack can do everything. The jack structure, structure size, and tensioning tonnage limit its range of use. The front clamping jack is small in volume, light in weight, and high in efficiency. The important thing is that it is a thousand card type steel strand reserved length is short, especially suitable for high altitude or small space position of the operation.

Components of Mono Jack
Hydraulic Mono Strand Jack
1. The jack adopts the front card type (that is, the tool anchor is in the front). The steel strand can be stretched with a reserved length of 200mm, which can save the material of prestressed tendons.
2. During the tensioning process, the jack can automatically clamp the prestressed tendons and retract the anchors, thereby reducing labor intensity and improving working speed.
3. The jack is designed with accessories with various functions, which can be selected according to needs during work.
4. The jack will not spin when working, which avoids the excessive elongation of the steel strand due to rotation.

Construction of Hydraulic Mono Strand Jack
Checking methods of Hydraulic Mono Strand Jack
(1) It is a relatively accurate method to calibrate the jack with the standard force juice (such as sensor, force ring, etc.) to be measured. And it is suitable for mobile units. It is recommended that the construction unit purchase sensors and a resistance strain gauge, and then make a self-made afterburner to verify the jack.
(2) Use the testing machine to check the jack. This method is a routine method used by many units.
(3) Two jacks on the item method; use a verified jack as the "standard" jack, and verify the jack by mutual jacking.
Correction requirements of Hydraulic Mono Strand Jack
(1) The jack must be marked with the name of the manufacturer, specification and model, serial number, date of manufacture, and large weighing.
(2) The surface of the jack must be complete, and no defects such as blisters, burrs, pores, and cracks that affect its quality are allowed.
(3) The measuring instruments involved in the calibration device must be within the period range and have valid verification certificates.
(4) When calibrating the jack, the oil inlet speed of the oil pump should be less than 0.1MPa/sec.
