The tensioner spring is designed to provide the necessary force to keep the excavator's tracks at the right tension.
It is typically made of high-quality, durable materials to withstand the rigors of construction and excavation work. The spring is engineered to handle the weight of the machine and the stress exerted on the tracks during operation.
Importance of Proper Track Tension:
Proper track tension is crucial for several reasons:
Reduced Wear and Tear: Correct tension helps distribute the load evenly across the track components, reducing wear and extending the lifespan of the tracks, sprockets, and idlers.
Improved Traction: Adequate tension ensures that the tracks maintain good contact with the ground, providing optimal traction for digging, lifting, and maneuvering.
Enhanced Fuel Efficiency: When tracks are correctly tensioned, the excavator operates more efficiently, reducing fuel consumption and operating costs.
Operator Comfort: Properly tensioned tracks result in a smoother ride for the operator, enhancing comfort during long working hours.
Compatibility:
The Hitachi EX120-2 Series Track Adjuster Tensioner Spring is specifically designed for use in the EX120-2 series excavators. These machines are known for their reliability and performance in various construction and excavation applications. Ensuring that the tensioner spring is compatible and properly installed is essential for maintaining the excavator's overall performance.
Maintenance and Replacement:
Like all mechanical components, tensioner springs require regular inspection and maintenance.
Over time, these springs can lose their tensioning capabilities due to wear and fatigue. When a spring loses its effectiveness, it should be promptly replaced to prevent damage to other undercarriage components and maintain optimal performance.
Installation and Adjustment:
Proper installation and adjustment of the tensioner spring are critical. This process should be carried out by trained technicians who are familiar with the specific requirements of the Hitachi EX120-2 series excavators. Incorrect installation or adjustment can lead to track issues, decreased performance, and potentially costly repairs.
Availability and Replacement Parts:
Replacement tensioner springs and associated components are typically available through authorized Hitachi dealers and parts suppliers. It's essential to source genuine Hitachi parts or high-quality aftermarket parts that meet or exceed OEM specifications to ensure reliable performance and longevity.
