RCH Single Acting Hollow Ram Hydraulic Jack

hydraulic cylinder jack

Product Features: Hollow plunger design allows for both pull and pushes forces.; Single-acting, spring return.; Nickel-plated, floating center tube on models over 20 tons increases product life.; Baked enamel finish for increased corrosion resistance; Collar threads for easy fixturing.;12 ton,20 ton,30 ton,60 ton, 100-ton hollow hydraulic cylinder available.

RCH-Series single acting hollow hydraulic cylinder is commonly used in testing, maintenance, and tensioning applications where the push and pull forces are needed. The hollow center plunger design makes it easy for the steel strand to pass through. The hollow plunger hydraulic jack is designed with a safety valve, and a built-in pressure relief valve to prevent overload, so as to protect the jack for safe operation. The connection of the device adopts a high-pressure hose and threaded joint connection, which is quick to use and overcomes the shortcomings of oil leakage of traditional joints. Hollow hydraulic jack is widely used in projects such as prestressed construction, bridge building, highway and railway construction, power plant power station building, equipment lifting, mechanical disassembling, etc.

RRH Double Acting Hollow Plunger Hydraulic Cylinder

Double Acting Hydraulic Hollow Ram

Double-acting can quickly retract and improve work efficiency; The safety valve protects the jack from damage during system failures; The dust ring reduces pollution and extends the service life of the jack; The hydraulic jack test method complies with the national standard ISO 10100:2001; Special stroke and aperture can be customized according to user needs; Matching 3/8″-18NPT quick hydraulic coupling and thread protection sleeve

Double-acting hollow hydraulic jacks are easy to operate and have a long service life. They are widely used in prestressing construction, bridge repair, road and railway construction, power plants, and power stations. Construction, equipment upgrade, mechanical disassembly, etc.

The center hole can provide steel strands, steel bars, etc. to pass through, and the center hole can be processed according to the needs of the user.

The double-acting hollow hydraulic jack is suitable for relatively long stroke operations, and at the same time, the hydraulic traction generated by it can be fully utilized in the operation of retracting the piston. The hollow plunger design can produce both thrust and tension. The double-acting design can quickly retract and merge. Accurately control the retraction distance.
