A backhoe is a versatile heavy machinery used for digging trenches and ditches on construction sites. It consists of a diesel tractor, front loader, and a hydraulically controlled digging bucket. It is considered the workhorse of construction equipment and can duplicate the work of a bulldozer, front loader, and excavator. An experienced operator can create a trench or installation hole in 15 minutes or less.
A backhoe, also known as a backhoe, is a versatile piece of heavy machinery used primarily for digging trenches and ditches on construction sites. A typical backhoe consists of a diesel tractor, a front loader and a hydraulically controlled digging bucket. The backhoe gets its name from the placement of the scoop bucket assembly at the rear of the tractor.
Many construction companies consider the backhoe to be the workhorse of construction equipment. It is often the only piece of heavy equipment carried on small to medium sized landscaping projects, as a backhoe can duplicate the work of a bulldozer, front loader and excavator. Since the equipment is mounted on a diesel tractor chassis, a backhoe loader can be driven directly to the different work areas. Other specialized machines often have to be towed around the site and require external power sources.
A backhoe operator must learn how to operate both a front loader and a backhoe. The front loader is not as complicated as the backhoe attachment, but the operator must operate a joystick while simultaneously driving the tractor. The front loader will remove dirt and excess material from the site or put it back into the hole, a process called backfilling. The front mounted bucket can also crush loose soil and create a level ground.
The backhoe attachment is where the skill and experience of the operator comes into play. The action of a backhoe loader is similar to that of a human reaching and pulling back a handful of sand on the beach, but humans accomplish this task through instinct and muscle memory. A backhoe uses three separate joints to duplicate motion. One joint extends the entire arm towards the area to be excavated, much like a human shoulder. The next joint works like an elbow, curling and flexing to pull the bucket back. The end joint works like a wrist, pulling and pushing the bucket through the ground. All these joints are operated by hydraulic pistons controlled by levers inside the tractor compartment.
When a backhoe operator is ready to dig a hole, they will first make sure they have enough room to swing the bucket to one side for dumping. Two stabilizing feet will then be lowered to provide additional grip and leverage. One lever extends the entire arm and bucket to the edge of the planned hole. Another lever bends the “elbow” until the bucket touches the ground. A different lever pushes the bucket into the ground with an inward arching motion. When the bucket is full, the entire boom is lifted and swung to the side for dumping. This process is repeated until the hole or trench is deep enough for the next stage of the project.
A backhoe hydraulic system can deliver tens of thousands of pounds of pressure, allowing it to do the work of many men with shovels. An experienced backhoe operator can create a trench or installation hole in 15 minutes or less. Those looking for a faster way to do major landscaping or underground pipe repairs at home might consider renting a backhoe loader after receiving some basic instruction. Anyone seeking employment in the construction or landscaping industry would benefit from learning how to operate a backhoe loader.
