Claims
- 1. A chute for transporting timber by gravity, comprising interconnected trough-shaped chute sections of polyethylene, the chute sections defining a concavity capable of receiving the timber and having smooth and elastically deformable polyethylene walls supporting the timber.
- 2. The chute of claim 1, wherein the interconnected polyethylene chute sections are positioned on the ground.
- 3. The chute of claim 1, wherein each of the chute sections has a length of approximately 4 to 7 m, a width of approximately 30 to 40 cm, and a height of approximately 30 to 40 cm.
- 4. The chute of claim 1, wherein the polyethylene walls have a thickness selected to retain elasticity while being resistant to breaking under impact forces of the timber transported through the chute sections by gravity.
- 5. A method of transporting timber by gravity over sloping terrain, comprising the steps of
- (a) providing a plurality of trough-shaped chute sections of polyethylene, each of the chute sections defining a concavity capable of receiving the timber and having smooth and elastically deformable polyethylene walls supporting the timber,
- (b) assembling the chute sections into a continuous trough,
- (c) securing the continuous trough to the sloping terrain, and
- (d) placing the timber into the trough for sliding therealong by gravity.
