Overview

The Cat 730 with a 17.5 m³ (23 yd³)/28 tonnes (31 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 to include the new cab design makes the 730 a more attractive proposition for our customers. Class leading levels of performance and new features such as Advanced Automatic Traction Control (AATC) and Assisted Hoisting Control create operator comfort, making a productive machine all day long while retaining all axle enclosed wet brakes and Advanced Productivity Electronic Control Strategy (APECS).

Sound Levels

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 maximum cooling fan’s 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 (3)
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.
Emissions
The 730 meets Tier 4 Final and Stage V emission standards.
Note (2)
Advertised power is tested per the specified standard in effect at the time of manufacture.
Note (1)
Advertised power is tested at 1,800 rpm.
Note (4)
Net power when the fan is at maximum speed is 254 kW (341 hp) per the SAE reference conditions.

Sound Levels

Note (2)
Hearing protection may be needed when operating with an open operator station and cab or when not properly maintained or with doors/windows open for extended periods or in noisy environments.

Optimal Loader/Truck Pass Matching

Note
An optimum system match gives you a major productivity advantage. The 730 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.

Diesel exhaust fluid (DEF) used in Cat SCR systems must meet the requirements outlined in ISO 22241-1. ISO 22241-1 requirements are met by many brands of DEF, including those that carry the AdBlue or API certifications.

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).

  • The Cat® C13 engine meets U.S. EPA Tier 4 Final, EU Stage V, Korea Stage V, and Japan 2014 emission standards.
  •     
  • Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels up to: 20% biodiesel FAME (fatty acid methyl ester) * or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.
  •     
  • Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
  •     
  • VisionLink® displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
  •     
  • Don't waste fuel idling. Cat VisionLink® online fleet monitoring helps you manage idle time and reduce fuel burn and greenhouse gas emissions.
  •     
  • Cat® Stability Assist for Articulated Trucks helps improve machine safety and uptime by increasing awareness of machine stability during operation.
  •     
  • Cat® Production Measurement provides real-time payload weighing which help you maximize productivity, reduce fuel burn and greenhouse gas emissions, all while improving job site efficiency and lowering costs.
*Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).
