Backhoe excavating machines are also known as the rear or back actors and are a type of excavating equipment with a digging bucket at the end of a two-part articulated arm. They are applied and used in numerous industries and fields such as construction site. One of the arms which is closest to the vehicle is known as the boom while the other section is known as the dipper or dipperstick and this section carries the bucket. The current backhoe excavating machines are powered by hydraulics.
The backhoes are not only useful for excavation, with additional attachment such as the tiltrotator it can work as an effective tool carrier. The attachments of the arm include the tilrotator, breaker, grapple or an auger. Many backhoes consist of quick-attach mounting systems which are used for simplified attachment mounting. This increases the machine’s utilization on the jobsite.
There are different types of backhoe loaders. One of them include the front-end loader which is used to lift and move materials, and to dif the ground to lay the foundation of a structure. Other uses include digging trenches, removing stumps and planting trees. Apart from that they are often used as attachments to a tractor.
The most powerful part of a backhoe is commonly on curling of the bucket, followed by the dipperstick and boom movements. A backhoe digs by drawing the earth backwards, compared to another category known as the bulldozer which lifts the earth up with a forward motion.
The earliest backhoe was developed by a British company JCB in 1953. Their first tractor was equipped with a hoe and a front-mounted loading bucket. This has started the first step towards using backhoe excavating machines and also as a standard pattern for future designs of hoe loaders. It is not unusual to see generic trademarks in United Kingdom and Ireland. Other manufacturers include Hitachi construction site Machinery, Hydrema, Komatsu, Gazar Loader, Ford Motor Company, Caterpillar Inc. and lots more.
JCB or J.C.Bamford Excavators Limited was first established in the 1945 in Staffordshire in England. The very first vehicle made by this company was a farm trailer. Now, JCB is one of the largest construction site equipment manufacturers globally and has factories in United Kingdom, Germany, America, China, India and Brazil. Most of the vehicles manufactured by JCB are variants of the backhoe excavating machines of different sizes. Apart from backhoe excavating machines, JCB also produce
tractors and Dieselmax which is a Land Speed Record vehicle.
Although backhoe excavation tools and machines are general purpose tools, one can design a backhoe in such a way to suit the purposes that it is intended to do, such as modifying a farm tractor with a front end loader and a rear hoe which is much stronger compared to the unmodified version.
Usually, backhoes are used together with loaders and bulldozers. Today, they are slowly replaced by multiple specialist tools such as the excavator and the specially-designed front end loader, and also mini-excavators. It is common to see a skidsteer and a mini excavator being used in many jobsites. However, backhoes are still popular for general use.
