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
Interior Cab:
72dB(A)
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.
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.
