Overview

The Cat 730C2 EJ, with a 16.9 m3 (22.1 yd3) 28 tonnes (31 tons) capacity, offers demonstrated reliability and durability, high performance and productivity, superior operator comfort and lower operating costs. Updating the successful 730C EJ to include all axle enclosed wet brakes makes the 730C2 EJ a more attractive proposition for our customers. Class leading levels of performance and operator comfort make for a productive machine all day long.

Note
The reference to Tier 4 Final/Stage IV includes U.S. EPA Tier 4 Final, EU Stage IV, Japan 2014 (Tier 4 Final), as well as Korea Tier 4.
Note
The power ratings apply at rated speed of 1,800 rpm when tested under the conditions for the specified standard.
Note
The net power advertised is the power available at the flywheel when the engine is equipped with alternator, air cleaner, muffler and fan at minimum speed.
Note
Net power when the fan is at maximum speed is 254 kW (341 hp) per the SAE reference conditions.
Emissions
The 730C2 EJ meets Tier 4 Final/Stage IV emission standards.
Note
DEF used in Cat SCR systems must meet the requirements outlined in the International Organization for Standardization (ISO) standard 22241-1. ISO 22241-1 requirements are met by many brands of DEF, including those that carry the AdBlue or API certifications.

Sound Levels

Note
The operator sound exposure Leq (equivalent sound pressure level) measured according to the work cycle procedures specified in ANSI/SAE J1166 OCT 98 is 76 dB(A), for the cab offered by Caterpillar, when properly installed and maintained and tested with the doors and windows closed.
Note
Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/windows open) for extended periods or in noisy environments.
