Motorized handling truck

A hand cart comprising a motor unit 60 mounted to a chassis 10, and an electric motor 61 connected to a differential transmission (62, Fig.2) with two lateral output shafts 621, wherein two caterpillar track modules 50 are connected to the shafts of the motor and swivel about this shaft independently between a position aligned with the chassis and a de­ployed position. A locking mechanism (551, 552, 553, 554, 555, Fig.4B) may be provided to lock the track modules in each position. Preferably a running element 70, including wheels 71, is provided, which can move between a retracted position above the tracks, and a lowered running position under the tracks. A telescopic handle 20 may be present, which could also include an arc-shaped grip (31, Fig.6B). Additionally, the device could include an auxiliary module (90, Fig.13) comprising three wheels, capable of swiveling between a retracted and deployed position via an electric actuator.
