Caterpillar D4
The Caterpillar D4 track-type tractor is a small bulldozer manufactured by Caterpillar Inc. Caterpillar first introduced the RD4 in 1936 as the diesel follow on to the successful CAT 30 gas model. The RD4 originally weighed in at , and used Caterpillar's D4400 engine, an inline four-cylinders, with a bore and stroke.Leffingwell, Randy (1996) ''Classic Farm Tractors: History of the Farm Tractor'' Motorbooks International, Osceola, Wisconsinpage 70 In 1935 Caterpillar had started the naming convention of "RD" for diesel or "R" for regular gasoline, followed by a number to indicate the relative engine size. In 1937 the "R" was dropped, and just a "D" was used for the diesel versions. At the time of introduction of the RD4, the D4400 engine produced about at the drawbar so the 4 indicated the relative engine power. The D4 U series was fitted with the more powerful D315 engine. The later D4 series engines quickly increased in power, so the number "4" just became a figure of merit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caterpillar Track
Continuous track is a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tires on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the tracks provide good trac ...

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 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 (and originally) 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. Etymology The word ''tractor'' was taken from Latin, being the agent noun of ''trahere'' "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term " traction motor" (1859). National variations In the UK, Ireland, Australia, India, Spain, Argentina, Slovenia, Serbia, Croatia, the Netherlands, and Germany, the word "tractor" u ...

Bulldozer
A bulldozer or dozer (also called a crawler) is a large, motorized machine equipped with a metal blade to the front for pushing material: soil, sand, snow, rubble, or rock during construction work. It travels most commonly on continuous tracks, though specialized models riding on large off-road tires are also produced. Its most popular accessory is a ripper, a large hook-like device mounted singly or in multiples in the rear to loosen dense materials. Bulldozers are used heavily in large and small scale construction, road building, minings and quarrying, on farms, in heavy industry factories, and in military applications in both peace and wartime. The word "bulldozer" refers only to a motorized unit fitted with a blade designed for pushing. The word is sometimes used inaccurately for other heavy equipment such as a front-end loader designed for carrying rather than pushing material. Description Typically, bulldozers are large and powerful tracked heavy equipment. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caterpillar Inc
Caterpillar Inc. (stock symbol CAT) is an American Fortune 100, ''Fortune'' 500 corporation and the world's largest construction-equipment manufacturer. In 2018, Caterpillar was ranked number 65 on the ''Fortune'' 500 list and number 238 on the Global ''Fortune'' 500 list. Caterpillar stock is a component of the Dow Jones Industrial Average. Caterpillar Inc. traces its origins to the 1925 merger of the Holt Manufacturing Company and the C. L. Best Tractor Company, creating a new entity, California-based Caterpillar Tractor Company. In 1986, the company reorganized itself as a Delaware corporation under the current name, Caterpillar Inc. It announced in January 2017 that over the course of that year, it would relocate its headquarters from Peoria, Illinois, to Deerfield, Illinois, scrapping plans from 2015 of building an $800 million new headquarters complex in downtown Peoria. Its headquarters are located in Irving, Texas, since 2022. The company also licenses and markets a li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trackson
Traxcavator was a namebrand of the ''Trackson Company'' of Milwaukee, Wisconsin. The word "Traxcavator" came from combining "tractor" and "excavator". Overview Trackson commenced business in Milwaukee in 1922 and initially built tracked attachments primarily for Fordson tractors, then later built tracked attachments for other tractor manufacturers. The early Trackson tracked attachments were popular on tractors used for road grader power units, as well as for tractors used on poor ground conditions. Expansion The Trackson company was owned by Armand Lamfrom Froehlich (1895-1951), and the chief engineer was Walter Stiemke. Sometime in the early 1930s, Walter Stiemke recognized the potential of combining the Trackson track system with the ''Lessman Manufacturing Company'' lifting mechanism, for digging or excavating. Stiemke convinced the owner of Trackson, Armand Lamfrom Froehlich (1895-1951), to buy the ''Lessman Manufacturing Co'' to pursue a marriage of the two systems - for ...

Caterpillar D3
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heavy Equipment
Heavy equipment or heavy machinery 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. Heavy equipment has been used since at least the 1st century BC when the ancient Roman engineer Vitruvius described a crane in ''De architectura'' when it was powered via human or animal labor. Heavy equipment functions through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied, making tasks which could take hundreds of people and weeks of labor without heavy equipment far less intensive in nature. Some equipment uses hydraulic drives as a primary source of motion. The term "plant" is used to refer to any mobile type of heavy machinery. History The use of heavy equipment has ...
