Modern Caterpillar equipment, is saturated with a large number of electronics, ranging from the illumination of devices and ending with electronic equipment. For the functioning of the entire Caterpillar electrical system, as for any electrical system need wires.
Caterpillar wiring comes in 2 types: high and low voltage. The first option is used in the ignition circuit, the second - to connect elements of the onboard Caterpillar electric system. Each wire is a collection of thin copper wires. Insulation is performed by winding Caterpillar wires.
The selection of such materials is dictated by the main requirements imposed on wires and Caterpillar wiring harnesses. Among them are: the flexibility of the wires, good conductive properties, resistance of the insulating material, both to high and to too low temperature conditions, non-propagation of the insulation of the combustion process, resistance to aggressive media such as gasoline or oil.
Caterpillar wiring is a collection of →
In Caterpillar electronics, an electronic control unit (ECU) is an embedded system that controls one or more electrical systems or subsystems in Caterpillar technology.
ECM (electronic engine control).
Caterpillar ECM - Engine Control Module.
Caterpillar ECU - Electronic Control Unit - electronic control unit - a general term for any electronic control unit.
By types of ECU can be divided into:
- Electronic (ECU),
- Engine control unit (ECM)
- Combined power transmission control unit
- Transmission control unit
- Brake control unit
- Central control module
- Central synchronization module
- Main electronic module,
- Suspension control module.
Taken together, these systems are sometimes referred to as Caterpillar computer hardware. Technically, this is not a single computer, but several blocks. Sometimes a single assembly includes several separate control modules.
Modern Caterpillar equipment include up to 80 ECU. Embedded software in a →
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 →
