730 EJ Articulated Truck

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.

  • Sound Levels
    Note (1)
    The declared dynamic operator sound pressure level is 72 ± 2 dB(A) when ISO 6396:2008 is used to measure the value for an enclosed cab. The measurement was conducted at 70% of the cooling fan’s maximum speed. The sound level may vary at different cooling fan speeds. The measurement was conducted with the cab doors and the cab windows closed. The cab was properly installed and maintained.
    Note (2)
    Hearing protection may be needed when operating with an open operator station and cab or when not properly maintained or doors/windows open for extended periods or in noisy environments.
