Cat has released the Gateless Coal Body designed for the 777F Mining Truck.
The 777F Gateless Coal Body joins a family of coal-specific bodies available for the Cat 785, 789 and 793 Mining Trucks.
Multiple body sizes are available for each model, allowing a productive match with any of the various coal densities encountered in worldwide mining operations. These bodies are also available as replacement upgrades for certain prior series models.
As an example, the 777F Gateless Coal Body is compatible with 777D Mining Trucks.
The Gateless Coal Body combines a robust understructure—modeled after the design of the Cat MSDII (Mine Specific Design) body—with a floor that angles upward toward the rear for nearly two-thirds of the body length.
To verify the payload potential and weight balance of the 777F Mining Truck fitted with the Gateless Coal Body, Caterpillar conducted a production and load-distribution study with three 777F trucks: one fitted with a conventional heavy-duty body with sideboard extensions; the second with sideboard extensions and an aftermarket tailgate; and the third with a Gateless Coal Body.
The 777F equipped with the Gateless Coal Body consistently carried 25% more payload than the truck with sideboards, and 7% more than the model with sideboards and tailgate.
