Hydraulic jack hollow plunger is used to stretch the prestressed tendons and compress the anchors. The hydraulic jack hollow is suitable for tensioning anchor bolts with steel strands or steel strands, supporting feet and tie rods. They can also be used as tie rod jacks to tighten the screw end rod anchors and fix them upwards. The hydraulic jack hollow plunger is suitable for tension testing and maintenance of cables, anchor bolts, thrust screws, and applications that require tension. Single-acting hydraulic cylinders have a unique hollow piston design that allows solid rods or steel ropes to pass through. The optional steel piston saddle can also be used as a normal top cover, especially for post-tensioning and pre-tensioning operations. The hollow hydraulic jack is widely used in construction, bridge construction, road and railway construction, power station construction, equipment upgrades, mechanical disassembly, hollow jacks have a telescopic effect, and the center hole can be used for wires, steel bars, etc. The center space can be processed according to user needs, and can also be made into hollow jacks with different specifications and different strokes, hydraulic stations and single-acting manual oil pumps are optional according to user requirements. Features of hydraulic jack hollow plunger:
1.The hollow piston design can obtain push-pull force.
2.The spring return structure and outer ring thread make installation more convenient.
3.The piston is plated with hard chrome to prevent scratches and corrosion.
4.The painted surface has strong corrosion resistance.
5.The hydraulic jack hollow plunger can be provided in complete sets (including hydraulic jacks, pumps, pressure gauges, joints, hoses).
When using the hydraulic jack hollow plunger, we should pay attention to the following:
1. The hollow hydraulic jack is connected to the oil pump through the high-pressure oil pipe, and the professional electrician connects the oil pump to the power source through the power cord. 2. Turn on the oil pump and make it run no less than 3 times. If the power is off, stop the pump to check and analyze the cause. Before calibrating the tension jack and the oil pump system, the jack must be in operation. After everything is normal, you can enter calibration or tensioning work.
