Pump engine for an agricultural trailer dolly

Hydraulic motor - hydraulic pump set for Dolly trolley, agricultural trailer. The so-called HYDROTIP can be used to create an external hydraulic system on equipment (e.g. dolly, agricultural trailer). The internal hydraulics (e.g. of an agricultural tractor) drives a hydraulic motor, which transmits power to a pump supplying e.g. a tipper. This assembly protects the internal hydraulic pump of the tractor (agricultural / semi-trailer) against mixing of oil and contamination from the trailer. Features of the engine-pump set:

- Thanks to the engine-pump assembly, we protect the internal hydraulics of the agricultural tractor.

- The set enables the operation of large-capacity agricultural trailers.

- The set is safe for the tractor - the pressure on the engine is the same as in the tractor,

- A safe solution for the hydraulic system tractor (no mixing with the semi-trailer oil),

- Free PTO - Hydrotip is driven from the tractor's external hydraulic outputs.

Connection diagram with the tractorExample tractor:

- system capacity: 46 l

- pump capacity: 48 l/min

- system pressure: 200 bar

Example semi-trailer:

- actuator capacity: 70 l <, - larger than the tractor system

- system capacity: 200 l/min

- system pressure: 200 bar

Engine - pump:

- power supply from the tractor: 48 l/min

- pressure on the engine: 160 bar - results from the pump load in HYDROTIP

- power supply semi-trailer: 32.8 l/min

- pump pressure: 200 bar - results from the load on the semi-trailer cylinder
