The Hitachi ZX120 and ZX130 are mid-sized hydraulic excavators designed for versatility and efficiency in various construction tasks.
They are known for their robust construction, powerful hydraulic systems, and advanced technology, making them suitable for a wide range of applications, from digging and trenching to demolition and material handling.
Importance of the Travel Device Kit:
The travel device kit, also referred to as the final drive assembly, is a critical component of the excavator's undercarriage system. It is responsible for converting the hydraulic power generated by the engine into mechanical power that drives the excavator's tracks, allowing it to move forward and backward. Therefore, the specifications of this kit are vital for the overall performance and durability of the excavator.
Key Specifications of the Hitachi ZX120 and ZX130 Travel Device Kit:
Drive Type: The travel device kit for these excavators typically employs a hydraulic motor-driven planetary gear reduction system. This system provides high torque and efficient power transmission to the tracks.
Gear Ratio: The gear ratio determines the speed and torque characteristics of the final drive. Different gear ratios may be available to suit various applications, allowing for adjustments in travel speed and power.
Load Capacity: The travel device kit is designed to withstand heavy loads and tough operating conditions. It should have a high load capacity to ensure the excavator's stability and reliability during operation.
Sealing System: To prevent contamination and maintain lubrication integrity, the final drive assembly should feature effective sealing systems, such as multiple seals and gaskets, to keep out dirt, water, and other debris.
Material and Durability: The components of the travel device kit should be constructed from high-quality materials, such as hardened steel, to ensure durability and long service life, even under demanding working conditions.
Maintenance Requirements: Easy access to components and simplified maintenance procedures are crucial for minimizing downtime and reducing overall operating costs.
Compatibility: The travel device kit should be designed to seamlessly integrate with the ZX120 and ZX130 excavators without the need for extensive modifications, ensuring a hassle-free installation process.
Efficiency: A well-designed final drive assembly will optimize the hydraulic power conversion process, maximizing the efficiency of the excavator's movement and reducing fuel consumption.
Safety Features: Some final drive assemblies may include safety features like overheat protection and pressure relief valves to prevent damage to the system and enhance operator safety.
Warranty and Support: Manufacturers often provide warranties and customer support for their travel device kits to give customers peace of mind and assistance in case of issues.
