Track Shoe for Hitachi EX1900-6 Excavator | 1024746

Product Overview

The track shoe (also known as track pad or track plate) is a critical undercarriage component of your Hitachi EX1900-6 mining excavator.

Track shoes provide essential traction, distribute the machine's massive weight across the ground surface, and protect the track chain from direct abrasion .

The Hitachi EX1900-6 is a 191–192 metric ton class mining excavator powered by a Cummins QSKTA38-CE engine producing 810 kW (1,102 PS). The backhoe configuration has an operating weight of 192,000 kg, while the loading shovel configuration weighs 191,000 kg . This genuine Hitachi track shoe (Part No. 1024746) is engineered to exacting OEM specifications for perfect fit, reliable performance, and maximum service life in demanding mining environments.

This is a genuine Hitachi original equipment part.
