Sikkerhetsretningslinjer

For sikker drift:

• Always select a cylinder with suitable capacity for the application.
• Ensure the lifting surface is stable and capable of supporting the load.
• Inspiser hydraulikkslanger, koblinger, and fittings before use.
• Never exceed the maximum working pressure of 700 bar.
• Ensure saddles are correctly installed before operation.
• Avoid side loading unless the application is specifically designed for it.
• Keep operators away from the lifting area during operation.
• Bruk passende personlig verneutstyr.

Ofte stilte spørsmål (Vanlige spørsmål)

1. What is a double acting hydraulic cylinder?

A double acting hydraulic cylinder uses hydraulic pressure to extend and retract the piston, providing controlled movement in both directions.

2. What is the capacity range of RR Series cylinders?

The LONGLOOD RR Series provides:

Kapasitet: 10–520 tons
Slag: 57–1219 mm

3. What are the advantages of a long stroke hydraulic cylinder?

Long stroke cylinders provide greater movement distance, making them ideal for:

• Large structure lifting
• Heavy equipment positioning
• Brokonstruksjon
• Industrial alignment applications

4. What pressure can the RR Series operate at?

Maksimalt driftstrykk er:

700 bar (10,000 psi)

5. What is the difference between single acting and double acting cylinders?

A single acting cylinder uses hydraulic pressure in one direction and returns by spring or load force, while a double acting cylinder uses hydraulic pressure for both extension and retraction.

6. Why are removable saddles used?

Removable hardened saddles protect the cylinder plunger during lifting and pressing operations and allow easy replacement when needed.

7. What are CR-400 couplers used for?

CR-400 couplers provide quick and secure hydraulic connections between the cylinder and hydraulic pump system.
