HYDROTIP can be used to create an external hydraulic system on equipment (e.g. dolly, agricultural trailer). The internal hydraulic system (e.g. of an agricultural tractor) drives the hydraulic motor, which transfers the drive to the pump that powers, for example, the tipping of the trailer. This unit protects the internal hydraulic pump of the tractor (agricultural / semi-truck) from mixing oil and contaminants from the trailer.
