Low Maintenance

Premium seals, покритие, устойчиво на корозия, and hard chrome-plated components reduce maintenance requirements and maximize service life.

Насоки за безопасност

For safe operation and extended service life:

• Always verify that all threaded connections and pulling accessories are securely installed before applying hydraulic pressure.
• Do not exceed the rated pulling capacity or 700 бар (10,000 PSI) operating pressure.
• Ensure the load is aligned with the cylinder centerline to avoid side loading.
• Inspect hydraulic hoses, съединители, pull rods, and seals before each use.
• Use only compatible hydraulic pumps and accessories.
• Keep the piston rod clean and lightly lubricated when recommended.
• Store the cylinder in a clean, dry environment after use.

Често задавани въпроси (Често задавани въпроси)

1. What is a hydraulic pull cylinder?

A hydraulic pull cylinder is designed to generate controlled pulling force using hydraulic pressure. It is commonly used for tensioning, extracting, дърпане, and removing heavy mechanical components.

2. What is the difference between a pull cylinder and a standard hydraulic cylinder?

A standard hydraulic cylinder primarily generates pushing force, while a pull cylinder is specifically designed to apply powerful tensile force for pulling applications such as shaft extraction and anchor bolt tensioning.
