UNIVERSAL operating system
Urus III UNI 300 3T is a system for operations both uphill and downhill, facilitating logistics operations in the field and taking advantage of the exisiting access roads amongst the harvest.
The control systems are placed in the operator's cabin, pedals and a swing arm which allow full functionality of the excavator when not operating with a winch.
Two hydraulic motors are positioned for the transport functions of the collecting truck, a 250cc one for the main line and another 160cc one for the return line, both individually controlled.
The hydraulic system used by Urus III UNI 300 3T is that of the base machine, for you can perform a bypass of the hydraulic hoses and connect them to the winch system with hydraulic steering pumps and directional valves. When operating, the system supplies both pressure and flow to the winch, and when it stops working, these are redirected to the base machine.
This system has been designed for heavy use, the guide rollers are mounted on the rear of the machine to guide the cable into the center of the box and minimize wear.
Universal use, for both uphill and downhill operations with the two different systems built into the machine.
Given that it uses the excavator's engine, no extra installation is required.
For 20 - 30 ton excavators
Hydraulic pump from the excavator is required, 350 bar - 410 l / min
The tower is permanently attached to the arm of the excavator with additional pulleys to guide the cable onto the excavator.
300 meters working range, which can be increased up to 500 meters approx.
3 tons maximum load, with a continuous drag force

Complete hydraulic systems for both the main and the return line
Hydraulic brake systems on both lines
Disc brake system for resistance
Main cable line of Ø 13 mm of 340mts 6x19 / (9/9/1) IWRC
Return cable line of Ø 13mm of 630 mts 6x19 IWRC, specific for forestry use.
Maximum force on the main line: 6.8 tons
Maximum force during the working distance 3.2 tons
Cable speed of 3.5 m / sec with a full load
Cable speed of 6 m / sec with an empty cart
Aprox. production of 170 tons per day, with a safe, downhill load of 2.9 tons (based on optimal operating conditions and tree size of 0,35 - 0.4 m3 per tree)
The UNI 300 URUS III 3T system can be mounted on 20 to 30 tons diggers for removing logs, both uphill and downhill. This equipment allows a very quick installation because it does not need cable retention, thereby reducing assembly time.
Even more, the excavator has its own mobility and may change the collection of spot without need of removing the anchor to the main line, and can easily be moved to another point of harvest within the front.
You can also a forestry grapple on the excavator and by detensioning the main cable car it can be self-evacuated with the grapple at the end of the arm. The Urus III 300 UNI 3T is a cutting-edge system for machining forest harvesting in mountainous areas
