Description

1. Two optional pumping loop systems: Double pump, double loop and single pump, single loop. Thos two special systems avoid hydraulic impact on changing direction.
2. Firstly adopted the technology that main oil back with filtering before air cooling. It has little impact and no peak value. Result in temperature controlled ideally.
3. The pipe tie-ins and hydraulic oil pipes are adopted German Rexroth and Italian products, which makes raise up oil volume under without adding oil tube diameter, and reduce oil leak.
4. The main oil tank\'s plunger is sealed in an assembling manner learned from abroad. The effect is excellent and it has well waterproof function .Using several encapsulating ring. It has long life-span.
5. In state of usual cylinder, a vat with a plunger is used as swing vat, which brings well buffer effect and swings more powerfully.
6. With a set of oil feeding technology, supplying oil timely is possible. The life of wearing parts is prolonged.
