The hydraulic jack refers to the light and small lifting equipment that uses the rigid lifting piece as the working device, and pushes the heavy objects in the small stroke of the top bracket or the bottom bracket.
The post tension stressing jack is a product developed according to foreign advanced technology and my country's actual situation. The post tension stressing jack for sale is equipped with the ultra-high pressure electric oil pump station produced by our factory, it realizes the tension function of the jack (also can be used for lifting), which is easy to operate and maintain. The post tension stressing jack is mainly suitable for construction of various prestressed concrete structures, and are widely used for roads, railways, power plants, bridges, bedrock and soil fixing, landslide treatment, overall lifting of large heavy objects, and disassembly of buckles. The use method and precautions of the post tension stressing jack master:
When using the post tension stressing jack, in addition to following common operating techniques and specifications, you should also pay attention to the following issues:
1 In order to ensure the correct measurement transmission type, please pair the selected jack and pump station, calibrate the measurement, draw the tensile force (or jack force) and oil pressure on the chart, and then proceed. A reasonable verification needs to be established.
In the following cases, you may need to readjust:
(1) After the post tension stressing jack is repaired
⑵ Replace the pressure gauge.
Other accidental damage to the equipment. 2 According to the "Jack structure and hydraulic system diagram", connect the jack to the pump station with a high-pressure hose, and perform the following steps.
(1) Start the operation of the pump station and adjust the safety valve to the working pressure (for pressure values, please refer to the calibration results above).
(2)When the handle of the reversing valve is rotated, the post tension stressing jack piston reciprocates to complete the tensioning or lifting operation.
(3) After the jack operation is completed, immediately turn off the power supply of the pump station, so that the overflow valve works for a long time, and the oil temperature rises sharply, and does not affect the service life of the pump station.
Pay close attention to the oil temperature in the hot season. If the oil temperature exceeds 70°C, cooling measures must be taken to maintain the normal operation of the pump station. If you are interested in the post tension stressing jack price, please contact us! Email:sales@leadcrete.com
