Hydraulic jack is also called hydraulic jack. Simple lifting equipment generally only has a lifting mechanism for lifting heavy objects. Simple structure, lightweight, easy to carry, and easy to move. Commonly used simple lifting equipment are hydraulic air bottle jacks, hydraulic vehicle positioning jacks, farm jacks, tackles, and hoists, etc. These types are very common on the market. Do you have any knowledge about the use of hydraulic jacks and the points that need to be paid attention to?

1. Hydraulic jacks are widely used in power maintenance, bridge repair, heavy lifting, static pile driving, foundation settlement, bridge, and ship repair and construction, especially in road and railway construction, mechanical adjustment, equipment disassembly, etc.
2. What should be paid attention to when using hydraulic jacks:

1) The bottom of the hydraulic jack should be flat and tough when using it. Oil-free wood planks to expand the pressure-bearing surface and ensure safety. Don't use an iron plate instead of a wood board to prevent sliding.

2) The lifting is required to be stable. After the heavy object is lifted, check for abnormal conditions. If there is no abnormal condition, the lifting can be continued. Do not lengthen the handle arbitrarily or operate it too hard.

Not overloaded, super high. When a red line appears on the plunger, it indicates that the rated height has been reached and the jacking should be stopped.

3) When several hydraulic jacks are working at the same time, a special person must be instructed to make the lifting or lowering proceed simultaneously. The wooden block should be supported between two adjacent hydraulic jacks to ensure the spacing to prevent sliding.

When using a hydraulic jack, always pay attention to the sealing part and the pipe joint part, and ensure that it is safe and reliable.

4) Hydraulic jacks are not suitable for places with acid, alkali, or corrosive gas.

  And the hydraulic jack will have some conditions after a period of time when it is in use. After all, no item can be used without damage, and we have to conduct daily maintenance on it. If you often work outdoors, there will be certain damages everywhere after wind and rain, so it is necessary to apply oil to protect it on weekdays. How to apply oil correctly?

1. Immersion method: Some small hydraulic jacks are immersed in anti-rust grease. The thickness of the oil film can be achieved by controlling the temperature or viscosity of the anti-rust grease so that a layer of anti-rust grease adheres to the surface.
2. Brushing method: When brushing, pay attention to evenly smear the surface of the hydraulic jack, avoid accumulation, and pay attention to prevent leakage.
3. Spraying method: some large anti-rust materials are not suitable for oiling by immersion method. Generally, use filtered compressed air with a pressure of about 0.7Mpa for spraying in a clean air place. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil. This method must use complete fire protection and labor protection measures.
