Crane Cylinders We Repair

At Cylinders, Inc., our team of experts is adept at diagnosing and repairing issues in a variety of crane cylinders, ensuring that your crane operates safely and efficiently:

  • Boom cylinders: These are essential for the movement and extension of the crane's boom. They allow for precise control and positioning, which is critical in lifting and moving loads.
  • Telescopic cylinders: Used in cranes with telescoping booms, these cylinders enable the boom to extend and retract, providing versatility in reach and height.
  • Outrigger cylinders: These cylinders are crucial for stabilizing the crane during operation. They extend to provide a wider base, ensuring the crane remains steady and balanced while lifting heavy loads.
  • Lift cylinders: Lift cylinders are key components in the vertical movement of the crane's load. They provide the lifting power that is central to a crane's function.
  • Steering cylinders: These cylinders assist in maneuvering the crane, especially in mobile cranes. They ensure smooth and responsive steering, which is vital for positioning the crane on work sites.
  • Tilt cylinders: Tilt cylinders are used to adjust the angle of certain crane components, such as the cab or the boom, enhancing the operator's control and visibility.
  • Swing cylinders: These cylinders enable the crane to rotate or swing, allowing the movement of the load in a horizontal plane.


Our skilled welders are proficient in advanced welding techniques that are crucial for repairing cracks or breaks in hydraulic cylinders. We use high-quality materials and precision welding methods to restore structural integrity to damaged cylinders.


Hydraulic cylinders are prone to leaks due to worn seals. We specialize in re-sealing services, replacing old or damaged seals with top-grade materials. This service not only stops leaks but also improves the overall efficiency and longevity of the cylinder.


Over time, the interior surface of the cylinder bore can become uneven or damaged. Our honing process smoothens these surfaces, ensuring that the piston can move seamlessly. This is essential for maintaining the precision and efficiency of the hydraulic system.

Chrome Plating

To prevent corrosion and wear, we offer chrome plating services for hydraulic cylinder rods. This process enhances the durability and longevity of the cylinder by creating a hard, smooth surface that reduces friction and resists environmental damage.

Rod Straightening

Bent rods in hydraulic cylinders can impair the functionality of the crane. Our team is equipped to straighten rods, restoring them to their original condition and ensuring smooth operation.

Pressure Testing

Safety is paramount, and to ensure that repaired cylinders can withstand operational stresses, we conduct rigorous pressure testing. This process checks for leaks and structural integrity under high-pressure conditions.

Polishing and Refinishing

We provide polishing and refinishing services to restore the external appearance of hydraulic cylinders, protecting them from corrosion and environmental factors.
