Backhoe

The backhoe is an industrial and mechanical machine that is used to achieve large excavations in all kinds of terrain. It has a bucket for excavation located at the end of an articulated arm in two different parts. This arm is usually placed on the back of a tractor and is used in earthworks for construction, piping and drainage.

What is a backhoe?

The backhoe is a machine that has as its purpose and use to make large excavations of soil in places where it is necessary to create a foundation, lay pipes or drainage. It is a bucket placed at the end of an arm of a tractor.

What is the backhoe for?

Backhoes are used to perform earth excavation processes, different types of trench openings for pipe laying and drainage are used to make deep holes that will be filled later, for example, the foundations of houses and buildings. They are widely used in general construction as they provide speed and quality. In building demolitions, to break street asphalt and to achieve a proper paving process in large and small cities. They are widely used in places where the use of some equipment is not useful. In addition, they are a precise source of cost and time reduction in the different works in which they are used.

Characteristics of backhoe

• It consists of an assembly of three different pieces of mobile earthmoving equipment: a tractor, a loader and a backhoe.
• It allows the tools to move quickly and safely.
• It can transport large quantities of material depending on the size of the container.
• It is mainly designed for excavating land.
• The container where the material is deposited is known as a bucket.
• The backhoe itself has three parts: the bucket, the stick and the boom.
• It is also known as a mechanical shovel.

History

In 1950, the well-known crawler tractor was used in the construction area. This instrument had proven to be a very useful piece of equipment; however, company experts were looking for ways to increase its usefulness, efficiency and versatility. At that time, Essex company located in England and known as Whitlock Bros. assured its customers and the world that they had succeeded in creating the world’s first backhoe loader. The company had created an accessory called Dinjum Digger and conducted a series of experiments in 1951. Sometime later, the company incorporated a hydraulic loader, thus creating the first backhoe loader. Joseph Cyril Bamford was the founder of the JBC company and had great experience in the construction of hydraulic loaders. On a trip to Norway he saw the great potential of the backhoe loader, bought one and took it to his place of residence to test its capabilities. In 1953, he had succeeded in improving the design and had built the first accessory included in the machine. She manufactured the product as JBC MK1 and in 1958, she was able to launch the first integrated backhoe.

Parts

The parts that make up a backhoe are:

• Point of union between the arm and the boom.
• Bucket hydraulic cylinder.
• Articulation link.
• Running gears.
• Chassis or frame.
• Engine compartment.
• Operator’s cab.
• Boom or boom hydraulic cylinders.
• Boom or boom.
• Arm hydraulic cylinder.

Types of backhoe loaders

Bucket excavators are also known as excavator shovels or mechanical shovels. They are used for vertical type excavations, well production and mining. They can be assembled on tires or on crawlers and have the ability to rotate on themselves with the help of an axis of up to 360º.

Another type of backhoe loaders are hydraulic excavators. Their price is more affordable, and their power is the same. Unlike mechanical shovels, they work on the ground from top to bottom and are quicker to load material. The pushing shovel has the bucket upwards and can unload from a higher height. It is mainly used in mining.

How do you drive a backhoe?

The backhoe works like a normal excavator by digging in the opposite direction of the vehicle. They are hydraulically controlled. The machine is stabilized through legs that are responsible for reducing tension by sending the weight to the machine and tires. It works thanks to the tractor driver. First, the assembly is placed in the required place, the tractor is parked, and the driver’s seat is turned to the front. In this position, the driver can choose whether to unfold the stabilizer feet when the tractor is not on solid ground, or to avoid this passage when the ground is sufficiently stable. After the backhoe is in the correct position, the operator or driver manipulates the controls by means of levers, one works to move the boom and the other is to move the bucket stick.
