Heavy-duty lifting, pushing and tensioning operations are the backbone of many industrial sectors, including bridge construction, equipment maintenance, shipbuilding, mining and heavy machinery installation. As engineering projects keep growing in scale and technical requirements become stricter, the demand for high-performance hydraulic cylinders with stable output, high safety and long service life continues to rise. The CLRG series double acting high tonnage hydraulic cylinder from Galaxy Machinery is engineered to meet these challenging industrial demands.
The CLRG series covers a wide capacity range from 50 ton to 800 ton, with available strokes from 50 mm to 300 mm, and a maximum working pressure up to 700 bar. Adopting double acting hydraulic return design, this series delivers powered extension and powered retraction, greatly improving work efficiency compared with single acting cylinders that rely on spring or gravity reset. This feature is especially valuable for repeated lifting and positioning tasks in tight construction spaces.
Durability is built into every component of the CLRG cylinder. Its plunger is made of high-quality steel with hard chrome plating. The plunger wiper effectively keeps dirt, dust and debris out of the cylinder interior, protecting the sealing system and extending service life. A specially painted surface provides excellent corrosion resistance, allowing the unit to work reliably under harsh outdoor and workshop environments. The exclusive guide ring absorbs eccentric loads and reduces galling and wear on the cylinder liner, minimizing maintenance frequency and downtime.
Safety is the core design priority. An integrated safety valve stops accidental overpressure to protect both the cylinder and operators. Removable hardened saddles safeguard the plunger during lifting and pressing work. Base mounting holes make fixture installation simple and stable. All CLRG models come with quick couplings (NPT3/8"-18) and dust-proof caps. Optional tilt saddles and flow control one-way check valves can be selected to realize self-locking, preventing instant retraction of the cylinder and adding extra security for critical load holding applications.
The CLRG series offers complete size options with fully documented dimensional parameters, including collapsed height, extended height, bore diameter, plunger diameter, mounting hole specs and weight data. Customers can easily select the right model according to load requirement, working space and travel distance. Matching high-pressure hoses and hydraulic pumps are available for a complete hydraulic system. Customized cylinders are also supported for special working conditions.
In today's industrial landscape, project owners and contractors are looking for hydraulic tools that balance heavy load capacity, operational safety and long-term cost efficiency. The CLRG double acting high tonnage hydraulic cylinder combines robust mechanical design, comprehensive safety features and flexible configuration options. It has become a trusted choice for heavy lifting, structural jacking, equipment alignment and heavy load tensioning tasks worldwide.
Whether you are working on infrastructure projects, plant maintenance or heavy industrial assembly, Galaxy Machinery CLRG hydraulic cylinders provide stable, controllable and safe power to handle your toughest heavy-duty jobs.
Core Product Advantages
Durability is embedded in the mechanical design of the CLRG cylinder. Its plunger uses high-quality steel with hard chrome plating for outstanding wear resistance. The built-in plunger wiper blocks dust and contaminants to protect internal seals and extend service life. A dedicated guide ring absorbs eccentric loads, reducing liner galling and abrasion. Special surface coating enhances corrosion resistance, allowing continuous operation in harsh outdoor and workshop environments.
Safety remains the top priority. Every CLRG cylinder is fitted with an internal safety valve to avoid damage caused by accidental overpressure. Removable hardened saddles protect the plunger during lifting and pressing tasks. Base mounting holes support secure fixture installation. Standard accessories include NPT3/8"-18 quick couplings and dust-proof caps. Optional tilt saddles and flow control one-way check valves can be added to achieve load self-locking, preventing sudden cylinder retraction during critical load holding.
Full dimensional data covering collapsed height, extended height, bore and plunger diameters, mounting hole specifications and weight is provided for all models. Matching high-pressure hoses and hydraulic pumps are available to build a complete hydraulic system. Customized cylinders can also be manufactured for special working scenarios.
Conclusion
As industrial projects pursue higher efficiency and stricter safety standards, robust hydraulic lifting equipment becomes indispensable. The CLRG series double acting high tonnage hydraulic cylinder integrates strong load capacity, double-acting control, multiple safety mechanisms and anti-corrosion construction. It balances reliable performance, long service life and flexible configuration to meet diverse heavy-duty lifting, jacking and tensioning requirements across global industries. For infrastructure, plant maintenance and heavy assembly applications, Galaxy Machinery CLRG hydraulic cylinders serve as a dependable power partner to handle demanding heavy load operations safely and efficiently.
