Electric concrete transportation cart

A self-propelled, steerable electric cart comprising:

• wheels supporting the cart, the wheels comprising at least one steered rear wheel and at least one driven front wheel;
• a cargo bucket for hauling and discharging loads;
• a transaxle for driving said at least one driven wheel;
• a steering system adapted to be turned by a cart operator for steering said cart, wherein the steering system comprises a steering column shaft mechanically linked to said at least one steered rear wheel;
• a manual throttle;
• a throttle control module mechanically connected to the throttle;
• a hand grip for normally controlling said throttle control module;
• and,
• a steering system sensor associated with said steering system for deriving electrical control signals proportional to steering displacement, said control signals delivered to said throttle control module for limiting excessive speed;
• wherein the steering system comprising the elongated steering column shaft rotates when the operator steers the cart;
• a control collar mounted to said steering column shaft that rotates therewith, the control collar comprising a pivot connection point that rotates with the collar and steering column shaft;
• wherein the steering system sensor comprises a linear actuator with a displaceable plunger controlling a linear potentiometer that generates said electrical control signals in response to axial deflection;
• and,
• the linear actuator is connected at one end to said pivot connection point and at an opposite end to a fixed point.
