Overview

The Cat 730 EJ with a 16.9 m³ (22.1 yd³)/27.1 tonnes (30 tons) capacity, offers demonstrated reliability and durability, high performance and productivity and a new world-class cab to improve operator comfort and ease of operation Updating the successful 730C2 EJ to include the new cab design makes the 730 EJ a more attractive proposition for our customers. Class leading levels of performance and new features such as Advanced Automatic Traction Control (AATC) and Assisted Ejecting Control create operator comfort, making a productive machine all day long. The machines retain all axle enclosed wet brakes and Advanced Productivity Electronic Control Strategy (APECS).

Engine

Emissions
The 730 EJ meets Tier 4 Final and Stage V emission standards.
Note (4)
Net power when the fan is at maximum speed is 274 kW (367 hp) per the SAE reference conditions.
Note (3)
The net power advertised is the power available at the flywheel when the engine is equipped with alternator, air cleaner, aftertreatment and fan at minimum speed.
Note (2)
Advertised power is tested at 1,800 rpm.

Sound Levels

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.
Note (1)
The declared dynamic operator sound pressure level is 72 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.

Engine

Note (1)
Advertised power is tested per the specified standard in effect at the time of manufacture.
Note (5)
Meets U.S. EPA Tier 4 Final, EU Stage V, Korea Stage V, and Japan 2014 emission standards.

Optimal Loader/Truck Pass Matching

Note
An optimum system match gives you a major productivity advantage. The 730 EJ is an excellent match for the Cat 349/352 and 336 Hydraulic Excavators; and Cat 972, 966, 962 and 950 Wheel Loaders. Having matched loading and hauling tools results in increased production and lower system costs per unit of volume moved.

Air Conditioning System

Air Conditioning
The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a or R1234yf. See the label or instruction manual for identification of the gas. • If equipped with R134a (Global Warming Potential = 1430), the system contains 1.1 kg (2.4 lb) of refrigerant which has a CO2 equivalent of 1.716 metric tonnes (1.891 tons).
