Designed by the British Department of Agricultural engineering, a new tree-lifter is expected to make land clearance much easier. The designers were asked to create a prototype machine that would be small enough to fit on the back of a tractor and could lift several sizes of trees.
In the past, land clearance involved the knocking down of trees, but it was a separate task to dig out the tree roots. This new machine lifts the entire tree -- roots and all -- from the ground. Because the jaws, which grip the tree trunk, do not damage the tree, the machine could also have application in transplanting.
The production models of this prototype machine will sell for approximately 500 pounds sterling. The machine was designed primarily for Africa, where there is a great need for crop-growing land.
SYNOPSIS: This machine, being tested near Newcastle, England, makes land clearance child's play. This machine has a limitation in the size of tree it can lift, only because it was built as a small prototype. Technicians believe there is no limit to the size of tree that can be lifted.
The tree is actually levered from the ground, and if necessary can be carried around by tractor, or just dumped where it is. Another tree felled and the whole operation has taken just two minutes. Present methods involve knocking the tree over and then extracting the roots. This prototype shows that the tree and its roots can be cleared by just grabbing them and lifting them out. It will have tremendous application in Africa, and machines can be built to handle a variety of sizes and types of threes. The primary purpose of the machine is for clearance of land areas, but it could be used for transplanting, because the jaws do not damage the tree. It is though that production machines will be sold cheaply enough to make them profitable for a variety of uses.
The tree-lifter was designed by the British Department of Agricultural Engineering for Africa, where there is a great need for crop-growing land. The machine must be small enough to fit on the back of a tractor and be capable of lifting trees up to 14 inches in diameter and 60 feet high. The longest time is actually taken in backing the tractor up into position. Once it is correctly situated, massive jaws go around the tree trunk and pressure is put on by the tractor engine.
