Caterpillar's history began when Benjamin Holt, founder of Holt Manufacturing, successfully solved the problem of the steam tractor mobility in the late 1890s - early 1900s, when the tractors were drowned in the soft earth of California farms. He came up with wrapping wheels with wooden planks and fix their chains. The innovation was successful, and was coined a special term for it, "the caterpillar (caterpillar)», because the tractor was crawling on the ground, like a caterpillar. Caterpillar has introduced its product line by offering a 5 tracked tractors, as well as a diesel engine adapted to replace existing gasoline engines.

Caterpillar Hydraulic cylinder - volumetric hydraulic motor of reciprocating motion. The principle of operation of hydraulic cylinders is largely similar to the principle of the action of pneumatic cylinders. The moving part of the Caterpillar hydraulic cylinder, which may be a rod, a plunger or the cylinder body itself, performs reciprocating motion. The main parameters that characterize all Caterpillar hydraulic cylinders are the internal diameter, stroke length, rod diameter and nominal working fluid pressure. Caterpillar Hydraulic cylinders come in several types: piston, telescopic, plunger, two-sided and one-way. According to the type of attachment, Caterpillar hydraulic cylinders are divided into models with hinged fastening and rigid fastening. Caterpillar single-acting hydraulic cylinder makes effort on the movable rod, which is directed only to one side (the working stroke of the cylinder). In the opposite direction, the movable link simply moves back under the action
The Caterpillar hydraulic system works as follows: The diesel engine rotates the shaft of the Caterpillar hydraulic pump, which converts mechanical energy into energy hydraulic. The hydraulic fluid is piped into the Caterpillar hydraulic pump and the Caterpillar hydraulic cylinders through the Caterpillar control valve system and converted there into mechanical energy of rotation or reciprocating motion. After performing the work, the hydraulic fluid returns to the hydraulic oil tank and enters the Caterpillar hydraulic pump. The cycle of work is repeated. Exist two types of heavy equipment Hydraulic systems: A volumetric hydraulic system for its operation uses hydraulic motors and hydraulic pumps operating under high pressure up to 350 MPa. This system uses the principle of alternately filling the working chambers of the pump and the hydraulic motor with a hydraulic fluid and displacing it from there under high pressure. The speed of movement of the working fluid in suc
When hydraulic systems are in operation, it becomes necessary to change the flow direction of the working fluid in its individual sections in order to change the direction of movement of the machine's actuators; it is required to provide the necessary sequence of activation of these mechanisms, to discharge the Caterpillar pump and the hydraulic system from pressure, and so on. These and some other functions are performed by a special hydraulic device - the hydraulic Caterpillar control valve. In the manufacture of Caterpillar hydraulic control valves, steel castings, modified cast iron, high and low carbon steel grades, and bronze are used as structural materials. To protect individual elements of the Cat control valves from abrasive wear, sliding surfaces are cemented, nitrided and so on. The dimensions and mass of the Caterpillar control valve depend on the flow rate of the liquid through which the dimensions of the unit increase. Thanks to the hydraulic system, the
The Caterpillar top roller is part of the moving part of the Caterpillar track. Its purpose is to ensure minimum sagging of the upper part of the Caterpillar track. Caterpillar top rollers are made of steel and are used to support the upper section of the track in the track chassis, which includes several supporting Caterpillar top rollers. They are located on the carrier, respectively, are installed on both sides, between the Caterpillar drive and return wheels. The Caterpillar top roller for supporting the tracks and chassis includes a bearing block with a roller. This mechanism, which has the ability to rotate, connects to the suspension unit suspension Caterpillar undercarriage. The Caterpillar top roller (Caterpillar roller, Caterpillar upper roller) is a Caterpillar track element designed to support the upper part of the Caterpillar track and to facilitate tension that reduces sagging. The use of a lot support rollers reduces the force necessary for pulling the track. Also, Ca
Caterpillar Bottom Roller is a crawler drive element that is a movable support for a Caterpillar equipment (a tractor, bulldozer, excavator, etc.) that use Caterpillar track chains. The part is to be installed with Caterpillar bearings on the axles to the suspension of the running gear. Caterpillar bottom rollers are mounted on bearings on axles that are connected to the body through a suspension. In order to mitigate impacts on the caterpillar during the movement in a rough terrain, the Caterpillar rollers are usually made rubberized. It can also be made of composite materials. Caterpillar bottom rollers have an internal design based on a coil or cylindrical roller bearings. Thick-walled outer ring allows to withstand high radial loads. Types of Caterpillar Bottom Rollers: - Rubberized; - Not rubberized; - Rollers with internal cushioning. Caterpillar Bottom roller supports the following functions: - Improvement of the rotating Caterpillar track chain; - Reduct
Caterpillar track shoe - an integral part of the crawler chain Caterpillar construction machines on equipment such as excavators, lifting machines, bulldozers, tractors and more. Designed to reduce the specific pressure of the weight of the base machine on the surface, which ensures patency on weak soils. To work equipped with rubber Caterpillar tracks in urban areas, reducing noise and damage cover (asphalt, concrete and so on). For work in wetland conditions, arched track shoes are used. The Caterpillar shoe track is one of the components of the Caterpillar track. Caterpillar shoes tracks are cast or forged units of wear-resistant steel, having on the outer surface of the lugs on the inner surface - the guide ridges, and apertures which include the teeth of the drive wheels, and lugs, which includes connecting pins pivotally connecting the tracks with each other. According to the constructive implementation of the Caterpillar links, there are composite and integral castings. At
The Caterpillar track chain is an important part of the Caterpillar track, it consists of movable elements that are connected together by means of fingers and bushings. It is this part that comes into contact with the ground surface during operation and exerts pressure on it. Using a crawler chain allows you to reduce pressure on the soil, which increases the throughput of Caterpillar Heavy Equipment. The Caterpillar tracks consist of bushes into which the fingers are placed, so joints are formed, allowing the chains to fit tightly the guide and the driving wheel. Like any other equipment, the Caterpillar equipment, over time, requires replacement of worn out Caterpillar parts. If you need to replace spare parts like Caterpillar track chains, you should pay attention to such moments: the length of the crawler chain and the diameter. The Caterpillar track chain can be mounted on motor grader, tractor, bulldozer and excavator Caterpillar. Such products are characterized by a lon
Rotation of the working equipment of equipment to the place of unloading the bucket and a reverse rotation to the place of dripping are carried out by turning the turntable or the whole platform (for full-cycle Caterpillar excavators). The rotation takes approximately 60-70% of the working cycle time and significantly affects its overall duration. The hydrostatic Caterpillar Swing Motor just performs the function of turning in the horizontal plane of the working equipment relative to the running gear of the Caterpillar equipment. The Swing Caterpillar Motor consists of a sturdy steel casing, in which several pairs of Novikov gearing gears are compactly arranged, allowing the transfer of loads significantly exceeding the permissible values for involuntary engagement. On the low-speed shaft, on the splines, the output gear is attached, which is included in the open gearing with a gear ring of the turntable of the Caterpillar Heavy Equipment. A large cogwheel is mounted on the
The Caterpillar Final Drive is a design made up of gears and other operating elements that are driven by a gear train. The simplest Caterpillar Final Drive consists of a carrier. It is designed to fix the satellites relative to each other so that they move together. For proper operation of the Caterpillar Final Drive, it is necessary that one of the constituent parts of it is rigidly fixed to the casing. In the Caterpillar Final Drive, which is equipped with a carrier, the static part is exactly it. In addition, the crown or solar gear may be rigidly fixed. In the event that none of the parts of this unit is fixed, it is possible to separate one movement into several, or merge the two into one. Due to this design, the drive and driven shafts of the Caterpillar moving in one direction. Serves the Caterpillar Final Drive to ensure a lower gear and at the same time increase the torque. To ensure the operation of this mechanism, the rotating shaft of the Caterpillar joins its d
Caterpillar Sensors have a huge functional load. They are responsible for the serviceability and correct operation of the power unit, as well as provide convenience and performance of the work on the Caterpillar heavy equipment, as well as the safety of the operator of the equipment during direct movement or work. Sensors and devices that perform diagnostics of all mechanisms, aggregates and systems of Caterpillar heavy equipment, are necessary for the timely warning of the operator of possible malfunctions. Data from the Caterpillar sensors monitor the temperature, pressure, position of the parts, fluid levels, and the use of other equipment nodes or devices. Each Caterpillar sensor is responsible for its indicator or parameter. The number of sensors in each, even the smallest Caterpillar machine, is extremely large. The variety of functionality of Caterpillar sensors is enormous, as is the importance of each of them in the performance of Caterpillar technology in general.
As the name suggests, a Caterpillar starter for heavy equipment is used to start an internal combustion engine. To do this, it provides a primary rotation of the crankshaft with the required frequency. The starter is an integral part of the electrical system of any modern Caterpillar equipment. Structurally it is a four-pole DC motor, powered by a Caterpillar battery. The Caterpillar engine generates the energy necessary for the movement of the Caterpillar equipment, due to the speed of the Caterpillar crankshaft. All electrical equipment works from the same energy. In a stationary state, the engine is not capable of delivering either torque or electric energy. In this regard, it is necessary to "untwist" it with a special electric motor - a Caterpillar starter motor, and an external power source - a Caterpillar battery. On motors with diesel power system, as well as on high-power engines, a Caterpillar starter motor with a gearbox is installed. The planetary gearbox, c
Electrical equipment of any Caterpillar equipment includes an alternator Caterpillar or AC Caterpillar generator - a device that converts the mechanical energy received from a Caterpillar engine into an electrical one. Together with a voltage regulator, it is called an alternator set. Caterpillar alternators are installed on modern Caterpillar equipment. They meet the requirements to the greatest degree. Requirements for the Caterpillar alternator: - the output parameters of the Caterpillar alternator must be such that in any mode of motion of the machinery there is no progressive discharge of the Caterpillar battery; - The voltage in the onboard network of equipment powered by the Caterpillar alternator must be stable over a wide range of speed and load variations. The latter requirement is caused by the fact that the Caterpillar rechargeable battery is very sensitive to the degree of voltage stability. Too low voltage causes a low battery and, as a consequence, difficulti
To convert various types of energy into electrical, special devices are used. One of the simplest mechanisms is the DC Caterpillar generator. The DC Caterpillar generator is a device that converts mechanical energy into electrical energy for further use in an external circuit. The source of mechanical energy in this case can serve as any mechanical effort: the rotation of a special handle, the Caterpillar engine and so on. There are such types of DC Caterpillar generators: self-excitation inclusion and working on the principle of independent inclusion. The methods of excitation depend on the type of power supply of the device. The self-excited Caterpillar generator works from external sources, it can be a rechargeable battery. Unlike Caterpillar alternators (or AC Caterpillar generators), devices with a constant type of electricity need an uninterruptible power supply that constantly directs the DC current to the armature winding. Because of this, the field of application of s
Electric Caterpillar battery - a chemical source of current, a source of electro-driving force of reusable action. The main specificity is the reversibility of internal chemical processes. That provides its multiple cyclic use (through charge-discharge) for the accumulation of energy and autonomous power supply of various electrical devices and equipment, as well as to provide backup sources of energy in vehicles and Caterpillar heavy equipment. The most common now are: 1. Lead Acid is the most common type of battery used in Caterpillar's heavy equipment, or as an uninterruptible power supply in emergencies. 2. Nickel-cadmium (NiCd) - the most widely used as a replacement for a standard galvanic cell, also used in Caterpillar electric forklifts and other Caterpillar electrical equipment. 3. Nickel-metal hydride (NiMH) - also used as a replacement for a standard galvanic cell, in electric vehicles. Please note that Caterpillar acid batteries are not allowed for air tr
Belt transmission is the transmission of mechanical energy by means of a flexible element - the Caterpillar drive belt, due to frictional forces or engagement forces (Caterpillar timing belts). It can have both a constant and variable gear ratio, whose shafts can be with parallel and intersecting axes. The Caterpillar belt performs two tasks: it operates a gas distribution system and aggregates of additional equipment such as a Caterpillar generator, a Caterpillar air conditioner compressor and so on. There is a huge variety of drive belts: - Caterpillar V-belt - Toothed Caterpillar belt Also distinguish single-row belts and multi-row Caterpillar belts. All of the above belts have one task - to drive the Caterpillar pulley of additional equipment or to drive other systems of equipment. Caterpillar pulleys transmit torque using Caterpillar belts.

The plunger and piston Caterpillar water pump are widely distributed, as their work is effective at high final pressure. The purpose of the Caterpillar water pump in the cooling system is to pump the cooling liquid through the cooling system. The main task is to force the coolant into the cooling Caterpillar radiator, as a result of the operation of the Caterpillar thermostat and the start of a large circle of engine cooling. How does the Caterpillar piston water pump work? The principle of operation of the Caterpillar piston water pump is to pump the liquid by suction. What does it mean? The piston creates a translational motion, through which the liquid enters the cavity of the lower part of the device from a special tube. When the piston does reverse movement, the valve on the pipeline closes and thereby prevents the fluid from flowing back. However, another valve opens on the discharge pipe. At the primary suction it was closed. These processes are repeated again and again
The cooling system plays a very important role, since it prevents the engine from overheating. The most important element of the cooling system is the Caterpillar radiator, which provides effective cooling of the liquid. The cooling system performs the following functions: - heat the air in the ventilation, heating and air conditioning system; - cool the oil in the lubrication system; - cool the exhaust gases in the exhaust gas recirculation system; - cool the air in the turbo system. Most of the modern technology is equipped with a water cooling system, among which the advantages are an effective uniform cooling. In addition, the water cooling system has a low noise level. Cooling system design: - Caterpillar radiator; - Heater heat exchanger; - Oil radiator; - Expansion tank; - Thermostat; - Caterpillar water pump; - Caterpillar radiator fan; - Branch pipes; - Controls. The principle of the cooling system is as follows. Thanks to the
Caterpillar turbocharger is a technically sophisticated mechanism that uses the kinetic energy of the exhaust gases to increase the pressure inside the Caterpillar intake system. Compressing, a mixture of fuel and air increases the mass of the fuel charge inside the Caterpillar cylinders, which increases the caloric content and, consequently, the engine power. The essence of the Caterpillar turbocharger is the strongest compression of air that enters the engine and enriches the fuel mixture, creating a high explosion power in the cylinder - this greatly improves the mass ratio of the Caterpillar engine to its power. Based on this, it can be argued that an engine with a Caterpillar turbocharger produces much more useful energy than the same unit without it. The operating speed of the Caterpillar turbine can be about 250,000 - 280,000 rpm. For comparison, the speed of the internal combustion engine itself is 30 times less. And since the Caterpillar turbocharger works by exhaust gases,
Air or fuel / air mixture enters the cylinders through the Caterpillar intake manifold. The main purpose of the intake manifold is to ensure an even distribution of air or working mixture between the cylinders. This directly affects the efficiency of the Caterpillar engine. In addition, other nodes can be attached to the manifold. The principle of operation of the intake manifold of the Caterpillar engine is quite simple: air or its mixture with fuel, getting inside through the inlet, is divided into several streams, according to the number of cylinders of the engine. Pistons, moving downwards, create a vacuum in the collector, which can reach large values. This partial vacuum is also used to neutralize crankcase gases. They pass through the engine crankcase ventilation system into the Caterpillar intake manifold, mix with the fuel-air mixture or air and are burned in the cylinders. Until recently, the main material for the manufacture of the Caterpillar intake manifold of was al
Caterpillar air filter for the engine - a paper, felt or other air cleaner that prevents dust and dirt particles from entering the fuel / air mixture system. Just like the Caterpillar oil and fuel filter, the air contributes to a stable and trouble-free operation of the internal combustion engine. The purpose of the air filter For the smooth operation of the Caterpillar engine, as you know, you need air. If it contains mechanical impurities or dust particles, the functionality of the motor is impaired. The air filter serves as a reliable barrier to various kinds of contaminants. Replacing the Caterpillar air filter - a responsible process, to ignore which is unacceptable. Moreover, it needs to be done in a timely and regular manner. For Caterpillar heavy equipment, the filter change becomes especially urgent. The reason for this is the work of the Caterpillar heavy equipment in difficult conditions, such as quarries, mines, construction sites and so on, far from service organizat
