70 GK
70 GK is a professional forestry winch with a constant pulling force of 6,8 t. A thinner (lightweight) wire rope allows greater productivity and faster timber harvesting.
|
Forestry winch 70 GK with constant pulling force 6,8 t enables safe work, as the winch is positioned closer to the tractor, and the pulley is fixed lower, which puts the center of gravity of the winch lower. Therefore, there is less chance for the tractor to be lifted. It has an extra large drum capacity, which allows more wound up wire rope. For easy work there are large storage places (PATENT) on the front of the winch, that the dirt from the wheels of the tractor does not get between the chain and other equipment. In order to facilitate the manipulation and stacking of logs, there is also a hydraulic hinged butt plate. |

HOW DO WE PROVIDE A CONSTANT PULLING FORCE?
Active Force Control is a special pulling force measurement and regulation solution. The pulling force is measured directly on the wire rope and is electronically regulated. Thus, the pulling force does not depend on the wear of the clutch, temperature and humidity, the preload of the wire rope and the amount of wound wire rope on the drum. Thus, the pulling force remains the same at all times, the pulling rope is thinner and consequently longer, and the tractor can be of lower power. A lighter wire rope helps to increase productivity and faster wood harvesting on the one hand and to reduce user fatigue on the other.
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 taught 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.
UNWINDING DEVICE AND AUTO STOP
To make the wire rope unwinding easier you can choose a winch with an integrated unwinding device. This type of winch also 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.
The valve for adjusting the brake opening speed enables slower release of the wire rope tension. This prevents uncontrolled spinning of the drum and resulting entanglement of the wire rope.
The sensor measuring pulling force of the winch is directly installed on the pulling rope to enable precise measurement of the force on the pulling rope. The measured pulling rope force is regulated with the clutch.
Proportional valve for continuous pressure adjustment.
The drive consists of a worm gear enabling high gear ratios, and spur gears elements immersed in the oil bath which enables higher efficiency, reduces maintenance requirements and increases its life span.

The multi-plate clutch prevents overheating/slipping of the clutch (6 plates).
HAWE seated solenoid valve with a high-pressure filter integrated in the control block for preventing pressure loss.
Hydraulic hinged butt plate lowers the centre of gravity for easier timber handling and log stacking.
