工程机械 Hyundai R290-7 的 液压发动机 Hyundai R290-7

This travel motor assembly is a core drive component specifically optimized for the Hyundai R290-7 excavator. It integrates a high-efficiency hydraulic piston motor with a precision planetary reduction gear, designed to meet the rigorous operational demands of 30-ton class machinery across diverse and challenging terrains.

Smooth Power Response: Precisely tuned to the characteristics of the Hyundai hydraulic system, ensuring agile starting and braking while effectively minimizing hydraulic shock during operation.

Wear-Resistant Alloy Components: The core planetary gear set utilizes high-strength alloy steel treated with a precision vacuum heat-treatment process, delivering exceptional impact resistance when handling heavy-duty excavation and dozing loads.

Heavy-Duty Contamination-Resistant Sealing: Features a dual-cone floating seal system designed for mining and wetland environments; it effectively blocks mud and fine sand, protecting the cleanliness of critical internal gears and bearings and significantly extending maintenance intervals.

Installation Compatibility: Interfaces fully comply with the original manufacturer specifications for the R290-7 series, supporting "plug-and-play" installation without the need for modifications, thereby drastically reducing equipment downtime and maintenance costs.
