Часто задаваемые вопросы (Часто задаваемые вопросы)

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:

Емкость: 10–520 tons
Гладить: 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
