Caterpillar's articulated trucks are engineered to pair with specific excavator and wheel loader classes — the 730, for instance, is designed to match the Cat 336F/349F excavators and 950M-972M wheel loaders for optimum loading cycle efficiency. The hydraulic system covers dump body hoist control (efficient fast-cycle raise/lower), primary steering, and an automatic electro-hydraulic secondary steering backup that engages if primary pressure drops — a genuine safety feature specific to this machine class.
