When tree shears first ʜɪᴛ the UK market almost 15 years ago, Land & Water was an early user. For a number of reasons, using long-reach excavators in conjunction with tree shears is effective. Long-reach equipment can reach higher branches and remove them more quickly, safely, and affordably than alternative techniques.
The excavator can maintain a safe working distance from the tree and the river while working ᴄʟᴏsᴇ to it, keeping men away from the edge. The long-reach excavator and tree shear combination is an affordable option for many sites because quick cycle times guarantee high levels of output. All of the models in our fleet of excavators, including amphibious ones, come with tree shears.
Tree shears come in two primary varieties. The first is a “grab and hold shear” that holds the branch or tree after it has been chopped using hydraulic actuators.
The excavator can safely deposit the cut material on the ground and debris won’t fall to the ground as a result.
The object can then be handled and processed using the same instrument after being cut with a basic shear and falling to the ground.
The most popular shears are grabbed and hold shears, although if a site wants to lessen the chance of overloading and/or instability of the excavator, basic shears can be safer.
Early shears were only really flexible for cutting ᴄʟᴏsᴇ to vertical trees. To allow the user to cut at any angle, including horizontal branches, many shears today are equipped with a tilt mechanism or even a full 360-degree rotation.
All shears function by cutting the wood with a blade or blades, frequently in a manner similar to how gardeners use a large set of secateurs. Some slide the blade into the wood, some have two blades that are ᴄʟᴏsᴇ to the wood, some utilize hydraulic arms to drag the tree onto the static blade, etc. Tree shears should not be confused with harvesting heads, which may cut the wood with a hydraulic saw. Shears are now available in a variety of sizes, from little excavators that can cut wood up to 6″ or 8″ thick to larger units that can cut up to 18″ trees.
On-site planners and shear operators must make sure the attachment and machine are not overloaded and are utilized safely.
