Correct use of lifting platforms to eliminate hidden dangers



The use of hydraulic lifting platforms has become more and more extensive, mainly because he can meet the needs of different heights, the use of different occasions, has brought great help to people's use, the correct operation can benefit humans but The illegal operation will bring us life threats. I remember that when we used a lifting device in the past, it was generally a kind of fixed ladder. We had to climb up and there was no such machine equipment . It was very unfavorable for us. The fixed type of ladder has poor economic efficiency and low efficiency. The high cost of use is very low for our net profit. The initial use of hydraulic lifting platforms was in construction. The hydraulic lifting platform was the first choice for the construction site. The machinery can give us many high-level problems. For example, the high-rise building we built and the office buildings we have today are very high, but When using, we must pay attention to safety, and many times the hydraulic lifting platform is very high, so the greater the danger will be, so we must make preventive measures in the stability of the sky, remember to see the last time In the news, because the stability of the staff caused the fall of the hydraulic lifting platform, there are many accidents each year. This kind of accident has brought a heavy blow to our family, so to avoid this kind of thing When this happens, we need to carefully inspect the components of the hydraulic lifting platform to prevent accidents. The requirements of the hydraulic lifting platform during operation are very strict. In addition to regularly inspecting the parts, we must carefully check the interface and his service life. The operating procedures must be strict, which is responsible for the safety of the workers.

Operation procedures: 1. The lifting platform has been inspected and debugged before leaving the factory. Each technical indicator meets the design requirements. Only the power supply is used when it is used, and the hydraulic and electrical systems do not need to be adjusted. 2. Before the platform is used, it is necessary to carefully check the hydraulic and electrical systems, and no leakage or naked leakage can be used. 3. When the lift is in use, the four legs shall be firmly supported on a solid ground (in case the walking wheel is about to leave the ground). The sleeper may be used if necessary. 4. The lift can only be operated 1-3 times after empty running. 5. The center of gravity of the load should be as far as possible in the center of the workbench. 6. The movable doors at both ends of the guardrail should be locked and locked before they can be used. 7. When in use, tighten the return valve knob clockwise, push the handle of the manual reversing valve to the neutral position, start the motor to make the system work, then pull the reversing handle to the lifting position, and the platform will lift to reach the required position. The height then pushes the reversing handle to the neutral position, the lifting platform stops rising, and at the same time, the motor is turned off and the operation can be performed. When falling, loosen the return valve (counter-clockwise rotation). The platform can fall depending on its own weight. (Note: The motor cannot be reversed.) 8. When using the hand pump, first tighten the return valve knob clockwise, push the handle to the neutral position, and press the handle platform to lift. When falling, loosen the return valve platform and lower it.




Self-Expanding Packer

Structure: Made up of oil expanding type or water expanding type expandable elastomer material, mechanical pipe string, centralizer and ect. 

Usage:

1. Segregated completion: Horizontal well/large displacement well can be interlayer-packed to carry out sub-level exploitation;

2. Packing water bearing layer: pro-phase and anaphase water plugging operations can be carried out to cut off the water bearing layer with good plugging effect;

3. Separate-zone production:oil well can be interlayer-packed according to its producing layer to improve the protection;

4. Assisting well cementing: it can be used at the top and bottom of the casing to provide supplementary packing after the well cementing in case of the problem of channeling because of the bad cementation between the cement ring and the casing, guaranteeing the tightness and improving the cementing quality;

5. Simplifying the well cementing: with the simple construction technology, the well completion technology can be simplified and the well construction period can be shortened;

6. Sectional development of the reservoir: after development, oil production can be put into quickly without moving the pipe string. 

7. Intelligent completion: intelligent completion can be carried out together with slide bushing and other tools

8.Sand protection: provide the top mortise packing for horizontal gravel filler. 


Specifications:
1. ISO 9001/ API Q1 / ISO14001 / OHSAS 18001 Certificate
2. Large stocks Timely delivery
3. Professional
4. Good after-sale service
