Mobile lifting device and weighing device therefor
First Claim
1. Mobile lifting device comprising a mobile frame with a lifting mechanism for receiving and lifting a cargo thereon, the mobile lifting device further comprising a weighing device, wherein the weighing devices comprises a pressure or strain sensitive sensor and a display panel coupled to the sensor for recording and displaying a weight of the cargo, wherein the weighing device is assembled additionally to the frame, wherein the sensor is mounted to and is parallel over a part of the frame that is prone to mechanical deformation caused by the weight of the cargo, wherein the sensor does not bear the entire weight of the cargo but rather measures an indirect force of the cargo resulting from the mechanical deformation, and wherein the sensor records the deformation and generates it as an electronic signal.

Abstract
A mobile lifting device comprises a mobile frame (1, 12, 13) with a set of lift forks (3) for receiving a pallet thereon. The pallet truck is provided with a weighing device which comprises at least one pressure or strain-sensitive sensor (20) in addition to a display panel (21) for indicating thereon a value measured by the sensor. The sensor is connected firmly to a pan (12) of the frame and able to determine a mechanical deformation in that part of the frame. The weighing device comprises this sensor.
