- Floating sealing is applied to the cylinder cover and the open/close of the cover by hydraulic power, so changing rams is quick and convenient.
- Auxiliary oil cylinder means a smaller volume with the same functionality.
- Ram rubber has significant storage volume, and adopts self-contained sealing.
- Standard configuration includes a manual locking device to ensure the ram is closed tightly in the case of hydraulic pressure loss
- Both manual and hydraulic locking device and the auxiliary oil cylinder can be installed into different positions according to your requirements, and installation positions changed easily.
