Force sensing carriage for load carrying vehicle

A force sensing carriage for a load carrying vehicle with lift capability, comprising:

• a first carriage component configured for mounting in an upright position to the load carrying vehicle;
• a second carriage component for contacting a load to be moved with the load carrying vehicle, the second carriage component being positionable in an upright position and in alignment with the first carriage component;
• at least one bladder filled with a fluid at a predetermined pressure and positioned between the second carriage component and the first carriage component, wherein the bladder at least partially supports the second carriage component in an operating position in which a portion of the second carriage component is spaced away from the first carriage component, and wherein a current pressure in the bladder is influenced by forces exerted on the bladder by the second carriage component;
• and
• an indicator circuit linked to the bladder and comprising an indicator, wherein the indicator is configured to indicate a warning to an operator of the load carrying vehicle if the current pressure exceeds a predetermined threshold pressure.
