GE520H Hydraulic Crawler Excavator
GE520H is a 50-ton-class hydraulic crawler excavator designed for mining and large-scale earthmoving. Equipped with a 6.55 m boom, 2.5 m arm, and 3.2 m³ standard bucket, it is suited to quarry loading, overburden removal, bulk excavation, and hydraulic breaking.
Equipped with Cummins QSM11(III)-C375 electronically controlled diesel engine, this crawler excavator delivers 280 kW at 2,000 rpm. The excavator also integrates a self-cleaning cooling system, dedicated breaker controls, and cab protection measures to meet the demands of mining and quarry operations.

Features
- Self-Cleaning Cooling System
The semi-independent cooling system features a self-cleaning function to help maintain cooling performance in dusty working environments. - Intelligent Machine Monitoring
Fitted with an 8-inch high-definition display offers a clear, easy-to-read interface, while the electronic monitoring system provides maintenance reminders, fault self-diagnosis, and alarms to keep operators informed of machine condition. - Machine Management System
The excavator management system combines BeiDou dual-mode positioning with high-speed 4G communication for equipment positioning and data transmission. - Noise-Reducing Engine Compartment
A honeycomb air intake design optimizes airflow through the engine compartment, while improved sealing and sound insulation help reduce machine noise. - Dedicated Hydraulic Breaker Mode
A dedicated breaker program allows remote adjustment of hydraulic flow and pressure to accommodate different breaking requirements. - Attachment Compatibility
The hydraulic crawler excavator is configured to accommodate a hydraulic breaker with a 200 mm tool diameter and can be equipped with additional digging attachments to suit different excavation tasks. - Double-Grouser Track Shoes
Standard double-grouser track shoes provide traction for travel across mining terrain. - Oil-Bath Air Precleaner
A standard oil-bath air precleaner helps remove airborne contaminants before they reach the engine's main air filtration system, making the machine better suited to heavily dust-laden environments. - Cab Protection
Protective screens and protective glazing help shield the cab's roof, front, and right side from impacts caused by flying rock fragments and other hard debris.
