hollow plunger hydraulic jack

The double acting hollow plunger hydraulic jack for lifting can be equipped with a two-way manual oil pump or a two-way electric oil pump. Because of the through hole in the middle, the hollow jack not only has the lifting capacity of a general hydraulic jack, but also has the stretching and tensioning functions that the ordinary jack does not have. The through hole allows cables, steel ropes and other shafts to pass through. The hollow roof has double functions and hydraulic retraction. The double acting hollow plunger hydraulic jack for lifting is the first choice for various large-scale projects. It has the characteristics of convenient operation and control. The new technology and structure make the hollow roof jacks safer and last longer.

300 ton hollow plunger hydraulic cylinder combines all the design features of single-acting and the superiority of double-acting design, thereby improving the operation and use speed, especially in the relatively long stroke operation. The 300 ton hollow plunger hydraulic cylinder has a through hole in the piston center, which is widely used in nuclear power plants, tunnel engineering, underground engineering, construction and other occasions to realize the pre-tightening process, and can also be used in other similar needs.

New or long-term single-acting hollow hydraulic jacks, because there is more air in the cylinder, when the piston is used, the piston rod may show a slight jump phenomenon. The single acting hollow hydraulic jacks can be reciprocated 2-3 times without load to eliminate The air inside the cavity. Long-term idle jacks, because the seals do not work for a long time, causing the seals to harden, thus affecting the service life of the hydraulic jacks. Therefore, when the hydraulic jacks are not in use, the hydraulic jacks should be reciprocated 2-3 times per month.

The characteristics 200-ton single-acting steel hollow plunger 700 Bar hydraulic jack: The piston part is welded with copper, the piston rod is coated with hard chrome, never pulls the cylinder, and the wear resistance is strong. High-temperature baking varnish, surface abrasion resistance, corrosion resistance and impact. Single-acting design, spring retraction (reset). High-strength alloy steel is durable.

300ton single acting hollow plunger hydraulic cylinder description: The 300ton single acting hollow plunger hydraulic cylinder with pump has a large stroke and a strong lifting capacity, and is the best choice for maintenance, manufacturing, construction and other operations. All models can be processed according to customer requirements, and the bottom is designed with mounting holes, which makes the installation and positioning convenient.

In order to guarantee our 200tons hydraulic hollow jack cylinder with hydraulic power pack can be exported to European countries, we apply two CE Certificates for our 200tons hydraulic hollow jack cylinder and electric power pack. So it is no any problem that our hydraulic jack for sale to European countries. If you want to know more 20tons single acting hydraulic hollow jack cylinder information, please contact us!

700 bar RCH single acting hollow plunger lift ram piston hydraulic cylinder is suitable for high-tonnage lifting operations, and requires high precision control of object lifting and maintenance operations. In the tunnel pipe horizontal displacement installation, 700 bar RCH single acting hollow plunger lift ram piston hydraulic cylinder hydraulic reset design can quickly and effectively retract the piston to its original position, ready to advance the next pipe.
