Installed in the main hydraulic system of the excavator, typically near the engine compartment.
A hydraulic pump converts mechanical power into hydraulic power, supplying pressurized fluid to various hydraulic actuators like cylinders and motors. For example, on a Hitachi EX200-5 excavator, the main hydraulic pump might have a part number 9147280.
Located within the undercarriage of the excavator, directly connected to the track drive sprocket.
The travel final motor drive uses hydraulic power to rotate the tracks, enabling the excavator to move. For instance, a Hitachi ZX220-3 excavator's travel final motor drive assembly could have a part number 9267183.
Found in the hydraulic system, responsible for generating the flow of hydraulic fluid.
A hydraulic pump is the heart of the hydraulic system, providing the necessary pressure to operate various functions. On a Hitachi EX400-3, a common hydraulic pump part number is 4436047.
Integrated into the track assembly, providing the final reduction in speed and increase in torque to drive the tracks.
The travel final motor drive ensures the excavator has the power and control for movement. A Hitachi ZX350H-5G might use a travel final motor drive with part number 9286008.
Sits within the hydraulic circuit, drawing fluid from the reservoir and pushing it under pressure.
The primary function of a hydraulic pump is to create flow in the hydraulic system. For a Hitachi EX120-2, a hydraulic pump could have the part number 4237800.
Attached to the excavator's frame and connected to the tracks via gears.
The travel final motor drive converts hydraulic energy into the mechanical rotation of the tracks. A Hitachi ZX470H-3 might feature a travel final motor drive with part number 9276112.
A vital part of the hydraulic power unit, responsible for pressurizing hydraulic oil.
Without a functioning hydraulic pump, the excavator's hydraulic functions will not operate. A Hitachi EX270-5 excavator may use a hydraulic pump with part number 9196010.
Essential for the excavator's mobility, providing the torque needed to move the machine.
The travel final motor drive is crucial for navigating job sites. A Hitachi ZX130-5G could have a travel final motor drive with part number 9258237.
Located in the engine compartment and connected to the hydraulic tank and control valves.
The hydraulic pump ensures a constant supply of pressurized oil for the excavator's operations. For a Hitachi EX300-2, a hydraulic pump might have the part number 4364521.
Bolted to the side of the track frame, enabling the excavator to propel forward and backward.
The robust design of the travel final motor drive allows for reliable movement even in tough conditions. A Hitachi ZX330-3 excavator might use a travel final motor drive with part number 9271456.
