ABSTRACT:
This invention relates to a truck with a hand-operatable bed provided with wheels for use in moving, a hydraulic cylinder for lifting or lowering the bed, and a plunger pump for feeding oil into the hydraulic cylinder by pulling a pumping handle, which is characterized by being additionally provided with a load sensor that detects the change in the hydraulic pressure inside the cylinder, and an indicator that indicates that change calculated in terms of the weight of a cargo on the bed. The truck is also characterized in that an arm whose top is provided with a foot pedal, and a pumping handle receiver which receives a pumping handle, both the foot pedal and the pumping handle being used to pump oil in the cylinder, are separately supported by their own pivot, and the pivot of the pumping handle receiver is located in such a position between the pivot of the arm and a shaft of a pressing roller that presses down the arm in company with the pulling-down of the pumping handle as to differentiate the ascending pitch of the bed by one stroke of the pumping handle from that by one stroke of the foot pedal.
