1. On both ends of the low end of the high output, large amount of oil;
2. Low pressure use plunger type, improve the effective pressure;
3. Dual active, electromagnetic wired remote control , can solve the problem of large tonnage, long type hydraulic cylinder which reset too slow
4. Pressure overload protection device, avoid overpressure and damage the equipment;
5. Dual active, use three-potential four-way valve, can be forward, maintain, back, maintain the pressure of these two oil circuits, keep the cylinder staying.
