B. CONSTUCTION EQUIPMENT ROAD ROLLER
BULLDOZER
A bulldozer is a crawler (continuous tracked tractor) equipped with a substantial metal plate (known as a blade) used to push large quantities of soil, sand, rubble, or other such material during construction or conversion work and typically equipped at the rear with a claw-like device (known as a ripper) to loosen denselycompacted materials. CRANE
A crane is a type of machine, generally equipped with a hoist, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places. COMPACT OR EXCAVATOR
A road roller (sometimes called a roller-compactor, or just roller) is a compactor type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations, similar rollers are used also at landfills or in agriculture. LOADER
A loader (bucket loader, front loader, front-end loader, payloader, scoop, shovel, skip loader, or wheel loader) is a heavy equipment machine used in construction and sidewalk maintenance to move aside or load materials such as asphalt, demolition debris, dirt, snow, feed, gravel, logs, raw minerals, recycled material, rock, sand, woodchips, etc. into or onto another type of machinery (such as a dump truck, conveyor belt, feed-hopper, or railcar).
MINI
other construction equipment in that all movement and functions of the machine are accomplished through the transfer of hydraulic fluid. The compact excavator's work group and blade are activated by hydraulic fluid acting upon hydraulic cylinders. The excavator's slew (rotation) and travel functions are a re also activated by hydraulic fluid powering hydraulic motors. DRAGLINE EXCAVATOR
A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining. Draglines fall into two broad categories: those that are based on standard, lifting cranes and the heavy units which have to be built on- site.
TRACTOR
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery used in agriculture or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks. BACKHOE LOADER
A backhoe loader, also called a loader backhoe, digger, or colloquially shortened to backhoe, is a heavy equipment vehicle that consists of a tractor fitted with a shovel/bucket on the front and a small backhoe on the back. DUMP TRUCK
FORKLIFT TRUCK
A forklift truck (also called a lift truck, a fork truck, or a forklift) is a powered industrial truck used to lift and transport materials. The modern forklift was developed in the 1960s by various companies including the transmission manufacturing company Clark and the hoist company Yale & Towne Manufacturing.
A dump truck (or, UK, dumper truck) is a truck used for transporting loose material (such as sand, gravel, or dirt) for construction. A typical dump truck is equipped with a hydraulically operated open-box bed hinged at the rear, the front of which can be lifted to allow the contents to be deposited on the ground behind the truck at the site of delivery
ROADHEADER EXCAVATOR
Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform (known as the "house"). The house sits atop an undercarriage with tracks or wheels. A cableoperated excavator uses winches and steel ropes to accomplish the movements. They are a natural progression from the steam shovels and often called power shovels. RECLAMIER
A reclaimer's function is to recover bulk material such as ores and cereals from a stockpile. A stacker is used to stack the material. STEAM SHOVEL
A steam shovel is a large steam-powered excavating machine designed for lifting and moving material such as rock and soil. It is the earliest type of power shovel or excavator. TRENCHER
A trencher is a piece of construction equipment used to dig trenches, especially for laying pipes or 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. YARDER
A yarder is piece of logging equipment which uses a system of cables to pull or fly logs from the stump to the landing.
PAVER
A paver (paver finisher, asphalt finisher, paving machine) is a piece of construction equipment used to lay asphalt on roads, bridges, parking lots and other such places.
a piece of excavating equipment consisting of a boom-mounted cutting head, a loading device usually involving a conveyor, and a crawler travelling track to move the entire machine forward into the rock face.
TRACKED LOADER
A tracked loader is an engineering vehicle consisting of a tracked chassis with a loader for digging and loading material. The history of tracked loaders can be defined by three evolutions of their design. Each of these evolutions made the tracked loader a more viable and versatile tool in the excavation industry. These machines are capable in nearly every task, but master of none. REACH STACKER
A reach stacker is a vehicle used for handling intermodal cargo containers in small terminals or a mediumsized ports. Reach stackers are able to transport a container short distances very quickly and pile them in various rows depending on its access. A tunnel boring machine (TBM) also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They can bore through anything from hard rock to sand. Tunnel diameters can range from a metre (done with microTBMs) to 19.25 m to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drilling rather than TBMs.
