A backhoe loader, also called a loader backhoe, loader excavator, tractor excavator, [1] digger or colloquially shortened to backhoe within the industry, is a heavy equipment vehicle that consists of a tractor-like unit fitted with a loader-style shovel/bucket on the front and a backhoe on the back. Due to its (relatively) small size and versatility, backhoe loaders are very common in urban engineering and small construction projects (such as building a small house, fixing urban roads, etc.) as well as developing countries. This type of machine is similar to and derived from what is now known as a TLB (Tractor-Loader-Backhoe), which is to say, an agricultural tractor fitted with a front loader and rear backhoe attachment.
The true development of the backhoe actually began in 1947 by the inventors that started the Wain-Roy Corporation of Hubbardston, Massachusetts. In 1947 Wain-Roy Corporation developed and tested the first actual backhoes. In April 1948 Wain-Roy Corporation sold the first all-hydraulic backhoes, mounted to a Ford Model 8N tractor, to the Connecticut Light and Power Company for $705. [2]
Evolving in parallel to development in the U.S., backhoes were first produced in the UK in 1953 by JCB, but it was just a prototype. The world's first backhoe loader with factory warranty was introduced in the U.S. by J.I. Case in 1957. Their Model 320 was the world's first serial backhoe loader. Although based on a tractor, a backhoe loader was and is almost never called a tractor when both the loader and the backhoe are permanently attached. Backhoe loaders are also not generally used for towing and usually do not have a power take-off (PTO) as often this is used to drive the hydraulic pump operating the attachments. When the backhoe is permanently attached, the machine usually has a seat that can swivel to the rear to face the hoe controls. Removable backhoe attachments almost always have a separate seat on the attachment itself.
In Britain and Ireland they are commonly referred to simply as JCBs; they are popularly called "JCB" in India. In the United States, they are often referred to as "backhoes", although the term 'backhoe' only refers to one component.
In 1970, Hy-Dynamic, now a division of Bucyrus-Erie, manufacturer of the Dynahoe, was the first company to incorporate a four-wheel drive system into their backhoe loaders, allowing these models to go over almost any terrain with little difficulty. Since the backhoe was invented, several companies such as Caterpillar and John Deere have changed the backhoe's back arm to be slightly curved like that of an excavator, which can allow more maneuverability.
Backhoe loaders are very common and can be used for a wide variety of tasks: construction, small demolitions, light transportation of building materials, powering building equipment, digging holes/excavation, landscaping, breaking asphalt, and paving roads. Often, the backhoe bucket can also be replaced with powered attachments such as a breaker, grapple, auger, or a stump grinder. Enhanced articulation of attachments can be achieved with intermediate attachments such as the tiltrotator. Many backhoes feature quick coupler (quick-attach) mounting systems and auxiliary hydraulic circuits for simplified attachment mounting, increasing the machine's utilization on the job site. Some loader buckets have a retractable bottom or "clamshell", enabling it to empty its load more quickly and efficiently. Retractable-bottom loader buckets are also often used for grading and scraping. The front assembly may be a removable attachment or permanently mounted.
Because digging while on tires intrinsically causes the machine to rock, and the swinging weight of the backhoe could cause the vehicle to tip, most backhoe loaders use hydraulic outriggers or stabilizers at the rear when digging and lower the loader bucket for additional stability. This means that the bucket must be raised and the outriggers retracted when the vehicle needs to change positions, reducing efficiency. For this reason many companies offer miniature tracked excavators, which sacrifice the loader function and ability to be driven from site to site, for increased digging efficiency.
Their relatively small frame and precise control make backhoe-loaders very useful and common in urban engineering projects such as construction and repairs in areas too small for larger equipment. Their versatility and compact size makes them one of the most popular urban construction vehicles. For larger projects, a tracked excavator is generally used.
In recent years, small compact tractors have become very popular with private homeowners. Subcompact tractors, the size between a compact tractor and lawn tractor, are also often sold in backhoe loader setup, sometimes with a belly-mounted mower also included. These tractors offer private homeowners the ability to perform minor excavation projects.
A military engineering vehicle is a vehicle built for construction work or for the transportation of combat engineers on the battlefield. These vehicles may be modified civilian equipment or purpose-built military vehicles. The first appearance of such vehicles coincided with the appearance of the first tanks, these vehicles were modified Mark V tanks for bridging and mine clearance. Modern military engineering vehicles are expected to fulfill numerous roles such as; bulldozer, crane, grader, excavator, dump truck, breaching vehicle, bridging vehicle, military ferry, amphibious crossing vehicle, and combat engineer section carrier.
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially tillage, and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised.
A skid loader, skid-steer loader, SSL, or skidsteer is any of a class of compact heavy equipment with lift arms that can attach to a wide variety of buckets and other labor-saving tools or attachments.
A shovel is a tool used for digging, lifting, and moving bulk materials, such as soil, coal, gravel, snow, sand, or ore. Most shovels are hand tools consisting of a broad blade fixed to a medium-length handle. Shovel blades are usually made of sheet steel or hard plastics and are very strong. Shovel handles are usually made of wood or glass-reinforced plastic (fiberglass).
Excavators are heavy construction equipment primarily consisting of a boom, dipper, bucket and cab on a rotating platform known as the "house" - although the largest form ever, the dragline excavator, eliminated the dipper in favor of a line and winch.
A loader is a heavy equipment machine used in construction to move or load materials such as soil, rock, sand, demolition debris, etc. into or onto another type of machinery.
A backhoe—also called rear actor or back actor—is a type of excavating equipment, or excavator, consisting of a digging bucket on the end of a two-part articulated arm. It is typically mounted on the back of a tractor or front loader, the latter forming a "backhoe loader". The section of the arm closest to the vehicle is known as the boom, while the section that carries the bucket is known as the dipper, both terms derived from steam shovels. The boom, which is the long piece of the backhoe arm attached to the tractor through a pivot called the king-post, is located closest to the cab. It allows the arm to pivot left and right, typically through a range of 180 to 200 degrees, and also enables lifting and lowering movements.
Heavy equipment, heavy machinery, earthmovers, construction vehicles, or construction equipment, refers to heavy-duty vehicles specially designed to execute construction tasks, most frequently involving earthwork operations or other large construction tasks. Heavy equipment usually comprises five equipment systems: the implement, traction, structure, power train, and control/information.
A telescopic handler, also called a lull, telehandler, teleporter, reach forklift, or zoom boom, is a machine widely used in agriculture and industry. It is somewhat like a forklift but has a boom, making it more a crane than a forklift, with the increased versatility of a single telescopic boom that can extend forwards and upwards from the vehicle. The boom can be fitted with different attachments, such as a bucket, pallet forks, muck grab, or winch.
Case Construction Equipment is an Italian manufacturer of construction machinery. Along with CASE IH, Case Construction Equipment is a brand of CNH. Case produces construction equipment including excavators, motor graders, wheel loaders, vibratory compaction rollers, crawler dozers, skid steers, and compact track loaders.
A compact or mini excavator is a tracked or wheeled vehicle with an approximate operating weight from 0.7 to 8.5 tonnes. It generally includes a standard backfill blade and features independent boom swing.
A trencher is a piece of construction equipment used to dig trenches, especially for laying pipes or electrical cables, for installing drainage, or in preparation for trench warfare. Trenchers may range in size from walk-behind models, to attachments for a skid loader or tractor, to very heavy tracked heavy equipment.
A heavy equipment operator operates heavy equipment used in engineering and construction projects. Typically only skilled workers may operate heavy equipment, and there is specialized training for learning to use heavy equipment.
Hydrema is a manufacturer of earth moving machines based in Støvring, Denmark, founded in 1959. They are specialized in the manufacturing of high-quality machines and earth moving equipment. A variety of models are produced, including dump trucks, backhoe loaders and wheeled excavators, as well as two wheeled excavators and one dump truck for rail road use. Since 1996 they have also produced a mine clearing vehicle.
A bucket is a specialized container attached to a machine, as compared to a bucket adapted for manual use by a human being. It is a bulk material handling component.
GPS when applied in the earthmoving industry can be a viable asset to contractors and increase the overall efficiency of the job. Since GPS satellite positioning information is free to the public, it allows for everyone to take advantage of its uses. Heavy equipment manufacturers, in conjunction with GPS guidance system manufacturers, have been co-developing GPS guidance systems for heavy equipment since the late 1990s. These systems allow the equipment operator to use GPS position data to make decisions based on actual grade and design features. Some heavy equipment guidance systems can even operate the machine's implements automatically from a set design that was created for the particular jobsite. GPS guidance systems can have tolerances as small as two to three centimeters making them extremely accurate compared to relying on the operator's skill level. Since the machine's GPS system has the ability to know when it is off the design grade, this can reduce surveying and material costs required for a specific job.
Quick couplers are used with construction machines to allow the rapid change of working tools or buckets and attachments on the machine. They remove the need to use hammers to manually drive out and insert the mounting pins for attachments. They also bring with them additional safety risks that must be overcome by careful design and manufacture, and proper use.
