Sound Standards (1)
The operator sound pressure level measured according to work cycle procedures specified in ISO 6394 and 6396 is 75 dB(A) for cab offered by Caterpillar when properly installed, maintained, and tested with doors and windows closed.
Sound Standards (2)
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 a noisy environment.
Gross Machine Operating Weight is 521 631 kg (1,150,000 lb).
Production capabilities of the 794 AC truck are such that, under certain job conditions, TKPH (TMPH) capabilities could be exceeded and, therefore, limit production.
Caterpillar recommends the customer evaluate all job conditions and consult tire manufacturer for proper tire selection.
