ABSTRACT:
A load transport carriage, designed to be carried by a truck, having two pairs of wheels, one being a front pair which is located at a relatively higher level and the other a rear pair which is at a lower level. The wheels of the lower pair are hinged to a carriage frame that is pivotable and lockable in its upper position. Locking mechanism is provided for locking the carriage in an upright position, this locking mechanism including one or more feeler wheels which engage the rear of the truck as the carriage is moved onto the truck and which operate to adjust the length of an adjustable strut connected between the pivotal legs carrying the rear wheels and the carriage frame. The locking mechanism may be either a mechanical locking mechanism or a hydraulic locking mechanism involving a check valve which permits fluid to flow in only one direction into a piston chamber.
