The Simplex RCG1006 is a 104-ton, single-acting, high-tonnage hydraulic cylinder engineered for demanding lifting and load-handling applications where maximum strength and durability are essential. With a 5.91-inch stroke, this model delivers powerful vertical movement while maintaining a compact profile, making it ideal for construction jacking, infrastructure lifting, industrial maintenance, heavy equipment alignment, and permanent or temporary support work.
Simplex RCG Series Hydraulic Cylinders are built for heavy load applications, making them ideal for heavy-duty civil engineering applications. These powerful single acting, load return cylinders use the weight of the load to return the cylinder plunger to its starting position.
Each RCG Cylinder is manufactured using advanced technologies and undergoes rigorous testing to ensure complete safety and maximum performance.
The cylinder exterior is finished with an enamel coating to extend cylinder life, and a wiper protects the inner cylinder assembly from dirt, moisture, and other contaminants.

Part of the Simplex RCG-Series, these cylinders are built for extreme duty. The RCG1006 features a high-strength alloy steel body, oversize piston design for improved load distribution, and a single-acting, spring-return mechanism that simplifies operation and reduces setup time. The internal heavy-duty return spring provides reliable retraction when hydraulic pressure is released, making this cylinder well-suited for repetitive lifting cycles and field work.
Equipped with a removable grooved saddle, premium seals, and a standard 10,000 psi rating, the RCG1006 integrates easily with a wide range of hydraulic pumps and hoses. Designed for stability and long service life under high-load conditions, it is a trusted solution for contractors, rigging crews, and industrial maintenance teams who require safe and controlled heavy lifting.
104-ton lifting capacity:
Built for high-tonnage applications such as bridge lifting, foundation work, and heavy machinery service.
5.91-inch stroke:
Provides strong lifting capability while keeping overall cylinder height compact for tight-area applications.
Single-acting, spring-return design:
Hydraulic extension with automatic retraction offers fast, simple operation — especially beneficial for repetitive lifts.
High-tonnage construction:
Oversize piston, heavy-duty bearings, and reinforced steel body ensure stability and strength under extreme loads.
Removable grooved saddle:
Helps protect the piston top and improves load grip and alignment.
Standard 10,000 psi system compatibility:
Works with most industrial hydraulic pumps and connection systems.
Ideal for heavy infrastructure and industrial tasks:
Designed specifically for the toughest load-support and lifting conditions.
Single-acting only:
Retraction relies on the internal spring, which may be slower without load assistance.
Proper alignment required:
Like all high-tonnage cylinders, side-loading must be avoided to protect seals and ensure safe operation.
Heavy and robust:
Weight and footprint may require proper lifting equipment or multiple personnel for safe handling.
Medium stroke length:
Suitable for structural lifts and adjustments but not designed for long-travel operations requiring 10+ inches.
Bridge and infrastructure lifting
Structural shoring and alignment
Heavy machinery maintenance and positioning
Foundation and construction jacking
Industrial plant maintenance (steel mills, refineries, mining operations)
Load testing and support under high compressive forces
Rigging and equipment installation tasks where stability and tonnage capacity are critical
Position the cylinder on a stable, level, and load-rated surface before lifting.
Use only 10,000 psi-rated pumps, hoses, and fittings.
Maintain strict vertical alignment — avoid any angle or off-center loading.
Allow the spring-return mechanism to fully retract; never force retraction manually.
Protect hoses from abrasion, sharp edges, and pinch points.
Regularly inspect seals, couplers, saddle surfaces, and body condition — especially during heavy, frequent, or outdoor use.
Follow Simplex operating and safety specifications carefully — at 104 tons of force, adherence to proper setup is essential for safe operation.
Center hole cylinders operate at a maximum working pressure of 10,000 PSI and are designed for use with compatible high-pressure hydraulic systems.
