Vector Neutral Truck: A 10% Improvement to the Haulage Cycle

CIM Montreal 2003
Abstract The haulage cycle is the sequence which a haulage vehicle must first arrive at the loading area, then turn around and reverse into position. Once it is loaded, the vehicle leaves and travels to the unloading area, where again it must turn around and back up to unload. The cycle is repeated over and over again. The Vector Neutral Truck is a rubber-tired, self-propelled hauling vehicle designed such that it eliminates the requirement to turn around and back-up to either load or unload.

Typical Truck Cycle:

1.)Travel from the load station to the dump station.
2.)Turn around, stop and reverse into position.
3.)Dump load.
4.)Travel from the dump station to the load station.
5.)Turn around, stop and reverse into position.
6.)Load.

Vector Neutral Truck Cycle:

1.)Travel from the load station to the dump station.
2.)Stop and dump load.
3.)Travel from the dump station to the load station.
4.)Stop and load.

The Advantage is in the Difference:

1.)Shorter distance traveled.
2.)Fewer brake and steering actuations.
3.)Easier to automate.
4.)Easier to adapt for remote control operation.


The Vector Neutral Truck has the operator’s compartment, fluid reservoirs, and power train located mid-ship, all are supported by a full-length chassis. A dump container, open at the top, is capable of holding and transporting bulk materials such as sand, gravel, rocks, ore, aggregate, or other materials. One end of the container is hinged to the frame so it can be elevated and emptied, wherein a hydraulic system is used to control the dump system. A vision system is used to help increase the operators field of view. Power for movement of the vehicle will be delivered via an engine and transmission drive-train. The vehicle has two axles, one at each end of the chassis, which can articulate and turn opposite but equal of one another to provide the steering. The Vector Neutral Truck is designed to handle and operate the same regardless of which direction it is moving.
