Abstract

A traction assist system and method for heavy equipment on an incline or in other situations with poor or limited traction. In particular, a traction assist system for heavy equipment having an accessory such as a blade, the system including: a tether; an adaptation to the accessory allowing the tether to be placed to allow the accessory to function without disrupting the tether, such as through-holes in the blade; and an attachment point on the heavy equipment for attaching the tether to the heavy equipment. The adaptation will depend on the particular accessory involved but may generally be an adaptation allowing the tether to pass through the accessory.

Claims (23)

1. A traction assist system for heavy equipment having an accessory, the system comprising:

a tether configured such that a first end thereof can be attached to an object other than the heavy equipment, an accessory, and an attachment of the accessory thereof to provide traction assistance to the heavy equipment;

an adaptation to the accessory, wherein the accessory is a blade, allowing the tether to be placed to allow the accessory to function without disrupting the tether, wherein the adaptation is a through-hole passing through the accessory and the tether passes through the through-hole; and

an attachment point on the heavy equipment for attaching a second end of the tether.

2. A traction assist system according to claim 1 , wherein the attachment point is positioned on the heavy equipment at a point past an axle well that is adjacent to the accessory.

3. A traction assist system according to claim 1 , wherein the tether comprises a plurality of branches, the adaptation comprises a plurality of adaptations, and the attachment point comprises a plurality of attachment points.

4. A traction assist system according to claim 1 , wherein the heavy equipment is forestry equipment.

5. A traction assist system for heavy equipment having a bulldozer blade, the system comprising:

a tether configured such that a first end thereof can be attached to an object other than the heavy equipment, the bulldozer blade, and an attachment of the bulldozer blade thereof to provide traction assistance to the heavy equipment;

a through-hole provided in the bulldozer blade, the through-hole passing through the blade and the tether passes through the through-hole; and

an attachment point on the heavy equipment for attaching a second end of the tether.

6. A traction assist system according to claim 5 , wherein the attachment point is positioned on the heavy equipment at a point past an axle well that is adjacent to the bulldozer blade.

7. A traction assist system according to claim 5 , wherein the tether comprises a plurality of branches, the through-hole comprises a plurality of through-holes, and the attachment point comprises a plurality of attachment points.

8. A traction assist system according to claim 5 , wherein the heavy equipment is forestry equipment.

9. A traction assist system according to claim 8 , wherein the forestry equipment is a skidder.

10. A method for traction assist for heavy equipment having an accessory, the method comprising:

providing a tether having a first end configured to attach to an object other than the heavy equipment, an accessory, and an attachment of the accessory thereof;

adapting the accessory to allow the tether to pass through the accessory wherein the accessory is a blade and the adapting comprises providing a through-hole in the blade for the tether to pass through; and

attaching a second end of the tether to an attachment point on the heavy equipment such that the tether provides traction assistance to the heavy equipment as a whole.

11. A method according to claim 10 , wherein the tether comprises a plurality of branches, the adapting comprises a plurality of adaptations, and the attachment point comprises a plurality of attachment points.

12. A method according to claim 10 , wherein the heavy equipment is forestry equipment.

13. A method according to claim 12 , wherein the forestry equipment is a skidder.

14. A method according to claim 10 , wherein the attachment point is positioned on the heavy equipment at a point past an axle well that is adjacent to the blade.
