If you have ever needed to dig a small hole in the ground, a
shovel or hoe will help you do it. But if you've ever needed to dig a really
big hole in the ground, you might want to consider something a little more
efficient like a backhoe.
Design and controls
A backhoe, also known as a mechanical shovel, is a piece of
equipment primarily used to dig into the ground and remove large amounts of
dirt, gravel or sand. The backhoe consists of a long arm with an appendix at
the end, square and shaped like a shovel, known as a "bucket". The
backhoe is designed much like a human arm: three joints with something to grab
on the end. The upper arm is referred to as a "feather," while the
forearm is referred to as a "stick." The backhoe is regularly
attached to a tractor on the back, with a complementary tool known as a
"loader" on the front. The tractors specially designed for this
machinery also have stabilizing legs.
A backhoe works through the tractor driver. When the tractor
driver moves the assembly into place, he parks the vehicle and turns his seat
to the front. The earthworks
sunshine coast can choose to deploy the stabilizing legs if the tractor is
not on solid ground or if the surface the backhoe is to operate is especially
hard. Once completely in place, the operator must manipulate two lever
controls, one to move the boom and the other to the bucket stick, to make the
hydraulic backhoe work on the floor.
More than dig
Although backhoes are mainly designed to dig in residential
areas due to their compact size, they can also perform other functions. The
Caterpillar company has backhoes that, when attached with chains, can lift
heavy objects. A drill attachment allows the backhoe to dig circular holes,
while an electric hammer makes it capable of breaking concrete and asphalt. Replacing
the bucket with a gripper attachment allows the driver to lift things up, such
as downed trees.
