Часта задаюць пытанні (FAQ)

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:

Ёмістасць: 10–520 tons
Масла: 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
• Будаўніцтва мастоў
• Industrial alignment applications

4. What pressure can the RR Series operate at?
