Overview

Equipped to handle your unique hauling needs

The Cat® 730 EJ articulated truck offers a unique advantage by ejecting material in low-clearance areas—ideal for tunnels, overhead lines, or underground work. On-the-go ejecting cuts the need for extra equipment, speeding up cycles and boosting productivity on compact jobsites.

Benefits

RELIABLE PERFORMANCE

The 730 EJ allows you to eject statically on grades and side slopes with minimal carryback, while the C13B engine delivers the power you require, combined with relentless reliability.

BUILT-IN SAFETY

The 730 EJ is designed for safe and convenient access with ground level service, and the push blade ejects material from the body, helping to prevent an opportunity for rollover.

IMPROVED OPERATOR EFFICIENCY

Easily set job parameters with Body Height and Machine Speed Limiting, while improving operating behavior with optional Operator Coaching.
