Cat, Terex introduce new haul trucks

Two of the world’s largest manufacturers of construction and mining equipment have introduced new off-highway haulers.

Caterpillar Inc. says its new 777G off-highway truck brings improved performance, production and fuel efficiency in the 100-short-ton size class. The 777 was first introduced by Caterpillar in 1977, and the 777G replaces the 777F.

The 777G achieves greater production with seven percent more torque and new transmission controls that produce quick haul cycles with automotive quality shifting. The production increases are balanced with new fuel saving strategies that include configurable economy settings as well as an adaptive economy mode that automatically optimizes fuel consumption based on the user’s production baseline.

The new Terex TA400 Generation 9 articulated truck is designed to keep productivity levels high, fuel consumption low and cycle times short. Boasting a 444 hp Tier 4 interim compliant Scania DC13 engine, the TA400 has a maximum payload of 41.9 tons and a heaped capacity of 30.3 cu. yd.

A four-bar trailing arm suspension system contributes to this new Terex truck’s improved ride quality, says the company, allowing operators to travel faster and more comfortably on difficult terrain.
