Single drum winch for 3-point attachment – TAJFUN Type EGV 35A dated 9.2008


2. Short description<br />

Page 3<br />

• Mechanically controlled single drum winch for 3-point attachment, category 1/2 (ISO<br />

730); powered by tractor PTO-shaft;<br />

• Operated with control cord.<br />

(technical data see page 5).<br />

3. <strong>Test</strong> results<br />

Application field / required tractor<br />

The winch is primarily suited for yarding and skidding thin – for towed loads less than<br />

1.5 m 3 - in easy terrain.<br />

The mounted winch is particularly suitable for use in farmer forestry and private<br />

firewood harvesting.<br />

It is recommended to mount the winch on a 4WD agricultural tractor weighing at least<br />

2500 kg and with an engine power in excess of approx. 30 kW.<br />

For safer and more rational skidding it is recommended to improve the tractor axle load<br />

distribution by adding front weights.<br />

The relatively small winch does not noticeably affect the manoeuvrability of the tractor.<br />

The winch can also be attached to a quick-hitch.<br />

Load collecting, anchoring, rope speed<br />

The load is collected using the choker procedure or by hauling-in individual stems while<br />

winch is firmly anchored to the ground<br />

To avoid pitching the tractor thicker stems and large choker loads must be winched<br />

using the lower cable guide pulleys.<br />

Yarding with the control cord causes more damage to the stand and is more time<br />

consuming.<br />

The stacking shield provides adequate support.<br />

The drum capacity permits hauling-in stems from a distance of up to 70 m.<br />

Transport<br />

The load is either transported suspended from the rope over the lower cable guide<br />

pulleys or using the choker chains attached to the chain slots.<br />

Piling<br />

Stems can only be piled by pushing them together using the stacking shield.<br />

Availability, reliability, durability<br />

Page 4<br />

The mounted winches are reliable. Spooling quality is just good. No defects occurred<br />

during the test.<br />

Winch construction is robust and durable: No defects occurred during the test.<br />

The durability of the surface coating is good.<br />

Ergonomics (operation – physical effort)<br />

The operation of the winch is simple. The actuating forces required for hauling-in the<br />

rope, releasing the brake are within approved limits.<br />

Using the control cord, the effort required for attaining full line pull and releasing the<br />

brake under load is about 350 N. The total effort is nearly completely independent of<br />

the load.<br />

The control cord also enables the operator to winch and release the brake from the<br />

tractor.<br />

The effort required for uncoiling the rope from the drums is low (approx 50 N).<br />

Operator is forced to assume an unfavourable body posture during piling.<br />

Assembly time and maintenance<br />

The mounted winch can be attached to or removed from the tractor in less than 15 min.<br />

The time required for maintenance is low.<br />

Stability<br />

Two stabilizers provide safe support for the mounted winch on hard ground.<br />

Work safety<br />

The mounted winch TAJFUN Type EGV 35 A has been tested for work safety at the<br />

Deutsche Prüfstelle für Land- und Forsttechnik (DPLF) (GS-<strong>Test</strong>).<br />

Operator manual and spare parts list<br />

The operator manual and spare parts list are comprehensive and clear.<br />

Survey results<br />

The test results are confirmed by a survey among owners of type-identical mounted<br />

winches.<br />
