محرك هيدروليكي ZX470 لـ حفارة Hitachi ZX470

This travel motor (final drive) assembly is a power unit specifically engineered for the Hitachi ZX470 excavator. It seamlessly integrates a high-torque hydraulic motor with a multi-stage planetary reduction gear system, designed to deliver robust tractive force and superior gradeability for heavy-duty machinery.

**Precise Power Response:** Features an optimized valve plate design that ensures rapid response to operational commands, enabling a smooth transition from a standstill to active drive.

**Mining-Grade Sealing System:** Equipped with high-strength metal floating seals at critical points to effectively prevent the ingress of mud and water, ensuring resilience against the harsh, dusty, and corrosive environments typical of mining operations.

**High-Load Durability:** The planetary gear set undergoes specialized carburizing and hardening treatments to withstand the mechanical stresses of frequent heavy-load operations, thereby minimizing the risk of gear wear or breakage.

**Ease of Maintenance:** Interfaces strictly adhere to OEM standards, supporting direct, hassle-free installation and rapid replacement, which significantly reduces equipment downtime and maintenance costs.
