Large Tonnage Hydraulic Synchronous Strand Jack

Hydraulic Strand jack

 Working principle: With the cluster jack as the executive mechanism, the hydraulic pump station as the power equipment of Hydraulic Strand jack, the steel strand suspension load, the use of the jack upper and lower clamp (automatic tool anchor) alternating action and the relative movement of the jack piston and the cylinder along the steel strand, so that the weight rise (continuous translation) or the right amount of down. This principle of the Hydraulic Strand jack is the organic integration of prestressed anchor anchoring technology and hydraulic jack technology. Anchor the steel strand through the anchor, and then use the computer to centrally control the output flow and oil pressure of the hydraulic pump station (proportional valve, reversing valve and other driving devices), drive the lifting jack piston extension and contraction (displacement sensor device), and drive the steel strand and components to rise, fall and continuous translation. To realize the whole Hydraulic Strand jack and appropriate lowering of large components, the system has strong adaptability and reliability on the construction site.

1. Determine the type of use of Hydraulic Strand jack: Select the right Hydraulic Strand jack according to the purpose and bearing capacity.

2. Select the support point and operating space: Before using the jack, determine the support point and operating space to ensure that the support point or operating space will not be arbitrarily changed during the operation.

3. Check the jack: Check whether Hydraulic Strand jack is damaged or loose to ensure that the jack is in good condition.

4. Adjust the height: When operating the jack, first adjust Hydraulic Strand jack to close to the support.

5. Place the base: the base of Hydraulic Strand jack should be smoothly placed on the support.

1. Check whether the Hydraulic Strand jack is normal before use.
2. Hydraulic Strand jack should strictly comply with the provisions of the main parameters, avoid ultra-high overload, otherwise when the lifting height or lifting tonnage
When the limit is exceeded, serious oil leakage will occur at the top of the cylinder.
3. such as manual pump body oil amount is insufficient, need to add to the pump should be fully filtered N33# hydraulic oil to work
Do.
4. Please refer to the manual for Synchronous lifting electric pump.
5. The center of gravity to choose moderate, reasonable choice of jack point of impact, the bottom surface to pad flat, while taking into account the ground
Soft and hard conditions, whether to liner tough wood, placing is smooth, so as not to load down or tilt.
6. After lifting the heavy object, the heavy object should be supported firmly with the support in time, and the jack is prohibited as a support
Use. If you need to support heavy objects for a long time, choose CLL self-locking jack
7.  If you need several jacks lifting at the same time, in addition to the correct placement of the jack, should use multiple shunt valve, and each
The load of the jack should be balanced, and attention should be paid to keeping the lifting speed synchronized. The possibility of subsidence due to uneven weight must also be considered
The situation is to prevent the danger of tilting the object being lifted.
8. When Synchronous lifting is used, the quick joint of the manual pump is first connected to the top, and then the position is selected and the oil release screw on the oil pump is tightened to work. To lower the piston rod, manually he handwheel of the oil pump is slightly loosened in the counterclockwise direction, the cylinder is unloaded, and the piston rod is gradually lowered. Otherwise too fast a descent will be dangerous.
