WHAT IS A BACKHOE?
A backhoe is a heavy excavation equipment popularly referred to as digger, rear actor, or back actor, etc. its consists of a digging bucket on the end of a two-part articulated arm and usually mounted on the back of a tractor or front loader. If the equipment is mounted at the front loader, it will become the backhoe loader which the Ireland and UK refer to as JCB.
USES OF BACKHOE
A backhoe is a multipurpose civil engineering and agricultural farming machine whose uses are inevitable in any construction work and commercial farming.
With the heavy and stable tractor acting as the carrier, the section of the arm closest to the vehicle is known as the boom and the term “Dipper or Dipper-stick” refers to the section which carries the bucket. The boom is usually attached to the vehicle through a pivot known as the king-post enabling the arm to move left and right up to 180 degrees to 200 degrees.
WHY IT IS CALLED BACKHOE
The term backhoe was derived from the action of the shovel due to the way it digs and draws earth backward rather than lifting with a forward motion. Though some may assume the name to come from the location of the shovel on the tractor which is not correct rather it is based on the shovel’s action. The difference in shoveling with the human hand and the equipment is that human shoveling lifts packed load up without shift the remaining loads while the equipment shovel will have to shift the remaining loads back to have space for lifting.
BACKHOE DESIGNS AND CONFIGURATION
Experts said that the buckets on some backhoes may be reconfigured facing upward to make the bucket a hoe but the design has proven to be ineffective since the dimensions of other components in the equipment were not configured based on that design.
The level of the backhoe strength involves the bucket curling as the strongest, followed by the dipper arm while the boom movement has less power.
BACKHOE MANUFACTURING METHOD
The tractor-like vehicle with the backhoe at one end, a front loader on the other end and a swiveling seat for the operator is referred to as the BACKHOE LOADER. The manufacturing of the equipment can be carried out from the start to the final process of parts inclusions and couplings by the specialized firm.
However, it can still be made through the adjustment and equipping of an already existing farm tractor with a front-end loader. Despite the configured type shot-cut manufacturing method, the purpose-designed backhoe loaders from manufacturers are much stronger and efficient in performance.
BACKHOE & HYDRAULIC TECHNOLOGY
The advent of Hydraulic technology has changed the backhoe functionalities making the heavy machine to carry out more complex works other than the initially intended designed works. The fixing of the hydraulic powered attachments such as the tiltrotor, breaker, grapple or an auger, etc. the equipment could serve as an effective tool carrier. Some can feature quick coupler mounting system for simplified attachment mounting dramatically to increase the machine’s utilization at job sites.
BACKHOE FUNCTIONALITIES AND OTHER COMPETITIVE MACHINES
During construction jobs, the machine is usually deployed alongside with loader and bulldozer. However, when an excavator is using a backhoe it is referred to as a “trackhoe” in a common term by workers based on the action of the bucket. Excavators and specialty front-end loaders have displaced the backhoes to some extent especially following the rise of the min-excavators. Some modern construction site may have the Skidsteer and mini-excavators to fill the Backhoe’s role. Meanwhile, based on its general-purpose functions, the backhoe has proven to be indispensable with any other similar machine.
The crucial arrangement that can possibly be carried out using thee backhoe include the possibility of reversing the bucket to work in a power shovel configuration and the possibility of using the backhoe as a crane without anchoring the load to its teeth.
According to CAT equipment manufacturer detail, backhoe loaders provide superior digging, trenching, back-filling and material handling capability and can be used for many applications including:
General construction, landscaping, breaking of asphalt and paving.
The backhoe delivers the power and precise handling you need when operating in areas where using larger equipment is not practical.
HOW TO MAINTAIN A BACKHOE
- Having a routine maintenance and inspection is mandatory for backhoes, since minor problems may not be noticed until they appear big which could lead to a huge financial loss.
- The movable parts should be greased regularly to ease the flexibility of the body and reduce overall power consumption during the operations.
- The hydraulic components must be checked for any leakage and the hydraulic fluid should be refilled whenever its volume drops or changed completely whenever it had been contaminated with other fluid.
- Toxic chemicals must be kept away from the backhoe because of their potential to cause corrosion and rust rendering the machine parts damaged.
- Overloading the backhoe could create the chance for possible technical problems.
- The bucket and other major parts should be washed to ensure proper removal of mud and external objects after using the backhoe especially if it will be packed for a long time.
- It is necessary to always test-run the whole system before carrying out any operation to avoid unforeseen problems.
- Besides the above, common sense application is necessary when handling any heavy machine bearing in mind the potential damage they could cause in any serious accident which may include loss of human life.
HOW TO OPERATE A BACKHOE
The operation of the Backhoe machine is a step-by-step process and usually take duration of three to six months or above in the certification training, reading the steps online will not imply you can become an expert or know all the techniques rather the post will give foundational knowledge of things involve and how to operate it in emergency situation. When it comes to industrial applications, certifications and practical experience will always champion any other learning process.
Below are the highlights of the steps:
Open the bucket and sit properly at the operator seat, try and familiarize yourself with all the controls in the operator location and ask questions whenever the need arise especially regarding the controls in the location including the gears, levers and the meters, it is your duty to read and know the function each of them performs. Try moving some that are movable without starting the machine. To commence, the crane operator expert said “Nick Market says. First, put the stabilizers down to steady the backhoe, and release the boom lock. Push the left control forward to extend the backhoe’s stick. Push the right control to the right to open the bucket.” According to the popular mechanics’ article publication.
After starting the backhoe, identify where you are digging and carefully look around the environment to ensure there are no obstacles that could cause an accident when the machine swings. Swing the backhoe shovel to the place you want to dig and lower the boom by pushing the right control forward.
After lowering the boom the next will be to carry out the intended operation which we assumed to be digging. To dig, pull the left and right controls back at the same time to retract and raise the boom while keeping the bucket curled. It is not advisable to overfill the bucket. Having done that, push the left and right controls to the right to open the bucket, pull the stick toward the cap and dump the load. Raising the load up too high may can technical problem rather operate the machine at full throttle based on precision, speed, and control.
The operators are usually warned not to leave their seat whenever they are operating the backhoe or go underneath the machine. Rather following the operators’ manual from the manufacturer will always be the guideline. Ensure the operation had been stopped and boom lowered before carrying out any maintenance work.
After the whole operation lowers the boom, drive to the packing location and turn of the equipment and tractor.
