The HYPRO 755 VB is a HYPRO 755 processor mounted on a forestry trailer, without a crane, winch, pump or tank. It was developed for customers who had already their own forestry trailer and wanted to use it as a platform for the processor to cut on investment costs.
The HYPRO 755 VB is a sturdy harvesting machine with a working radius of 280°. It works on both sides of the trailer. The machine is controlled by a CAN bus with electrohydraulic control (EHC) with HYPRO 2 controls. A single push on a button allows to switch between the controls of the trailer and the processor. The new CAN bus from HYPRO works with Danfoss and Parker valves.
In principle, the processor can be mounted on any brand of forestry trailer on the market. If the hydraulics have enough flow and pressure, the processor can use the hydraulics of the trailer. Usually all forestry trailers with motorized wheels have hydraulic systems that are powerful enough for the HYPRO 755 VB. If the hydraulics are not strong enough, a HYPRO hydraulic tank and pump can be mounted on the front of the tractor to give the necessary power. The hydraulic system can be load-sensing or with an open circulation pumping. The load-sensing hydraulics will usually ensure a smoother, faster and more powerful operation of the processor.
The HYPRO 755 VB is easy to mount with the crane of the forestry trailer. It is fitted with tree lifting lugs for straps or chains to help lift the machine easily. It is attached to the trailer’s load banks, using a brace attachment with bolts. To remove, the entire processor is simply lifted away using the crane and then placed directly on the ground. Of course all hoses and cables are equipped with quick release couplings.
