The Cat® 740 raises the bar for operator comfort and control. Its redesigned, world‑class cab is built to deliver a smoother, smarter, more intuitive experience. With upgraded controls, built‑in transmission protection, hoist assist, advanced automatic traction control, stability‑assist rollover warnings, and an ECO mode that cuts fuel use, the 740 is engineered to keep productivity high and operating costs low.
A uniquely combined hoist and transmission lever allows for easy operation which suits a wide range of operator experience
Versatile configurations and tire options adapt to a variety of jobs, while a redesigned body boosts payload and durability. Adjustable seats and flexible cab layouts elevate comfort and productivity, keeping you efficient all day long.
Safety features boost operator confidence by making every shift more secure — from roll‑over prevention that keeps the cab and body stable to improved, cab entry that helps operators climb in with confidence.

|---|---|
| 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. |
| 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. |
