Forestry winch 70 GX

The 70 GX forestry winch has all the essential features for the professional forester: durable mechanism, strong construction, and complete control of the log manipulation.

70 GX

About the Machine

The 70 GX forestry winch with a pulling force of 65 kN is the smallest of the GX Uniforest PROFI series. Power, control, and durability are provided by the proportional brake (option), improved unwinding device, great drum capacity, and durable structure with convenient positioning of all the machine's vital parts.  

Safe forestry work with the 70 GX Profi winch is ensured by the renewed butt plate, made with stronger and at the same time lighter materials as well as with the redesigned window guard. User-friendly design and positioning of PTO attachment, handy distribution of the saw, pickaxe, and fuel canister holders, and partially opened chocker chain departments with big capacity improve accessibility to all important forestry tools. To facilitate the manipulation and stacking of logs, there is also a hydraulic hinged butt plate available.

Standard:

  • SMART 3in1
  • AUTO STOP function (limit switch)
  • Unwinding device with a powerful hydraulic motor
  • Maxi drum
  • Large and conveniently positioned storage spaces
  • The choker chain department is partially open and accessible from the above
  • Drive over bevel helical and spur gears
  • Strong and wide butt plate
  • Foldable window guard for tractor protection

Option:

  • Proportional brake
  • Hydraulic-hinged butt plate
Unwinding device and AUTO STOP

Unwinding device and AUTO STOP

An integrated unwinding device makes the wire rope unwinding easier and guarantees a constant tension of the wire rope between the unwinding pulley and the drum, thus preventing damage to the drum or pulley and enabling a longer service life.

AUTO STOP function (limit switch) automatically stops the function of winding the wire rope on the drum. This function prevents mechanical damages of the unwinding device, entanglement and wire rope damages.

Protected and easily accessible

Install the bracket for your auxiliary winch 6HWpro to the dedicated mounting-ready space. Connect it to the tractor with a separate hydraulic system and use one remote controller to operate the forestry and auxiliary winch.

UNILINK
UNILINK

The UNILINK remote controller is standard equipment for Profi single-drum winches. Different functions (optional upgrades) are marked as follows:

  • K = Antikipp
  • A = Proportional brake
  • H = Auxiliary winch

Adjustable Opening Time and Braking Force with a Proportional Brake

While the classic brake can be only set to the nominal braking force of the winch, the proportional valve allows the user to adjust the braking force with a remote controller to any value up to the maximum braking force of a winch.

Adjustable braking force (progressive brake system) ensures that the wire rope can be unwound in a controlled way without the unwinding device, provided that sufficient pulling force is applied to the rope between the winch and the load.

SMART 3in1

SMART 3in1

(1) When pulling logs with a tractor, you may encounter some obstacles on the road (hill, roots etc.). If the tractor is not able to overcome these obstacles, the unwinding function can be switched into the mode without the assistance of the unwinding device and you can continue driving with a tight wire rope between the winch and the load. (2) The unwinding device can be turned on and off without delay (the standard model has a 1.5-sec. delay). (3) The SMART 3in1 function ensures additional tension of the wire rope between the unwinding pulley and drum.

This function is only available with the remote controls Teleradio, Terra funk and manual console.

Standard equipment for models without proportional brake.

The throttle for adjusting the brake opening speed
The throttle for adjusting the brake opening speed

The throttle for adjusting the brake opening speed enables slower release of the wire rope tension. This prevents uncontrolled spinning of the drum, which often results in an entanglement of the wire rope.

Drive

“The main advantage of a proportional brake is that you can release the brake in a controlled way. This is done using a potentiometer on the remote control.”

Optional equipment

Adjustable braking force (proportional valve)
Adjustable braking force (proportional valve)

Adjustable braking force (progressive brake system) allows the wire rope to be unwound without the unwinding device, regardless of the force on the pulling rope between the winch and the load. Proportional valve enables continuous pressure adjustment.  

Wire rope
Wire rope

Recommended wire rope thickness according to the maximum wire rope length:

  • 12mm/130m 
  • 11mm/160m

The wire rope must be up to standard, the breaking force of the wire rope must be at least twice as much as the pulling force.
