The invention discloses a novel multi-functional manual hydraulic carrier and relates to the field of aided machinery for freight transportation. The novel multi-functional manual hydraulic carrier comprises a small handle, a large handle, a hydraulic jacking system, a linkage mechanism, front wheels, a rear wheel lifting mechanism and pallet boards. The small handle, the large handle and the hydraulic jacking system are arranged on the front wheels and used for controlling power output and pallet board lifting. The rear wheel lifting mechanism comprises rectangular beam support bars, auxiliary wheels, half sleeve barrels and rear wheels. The rear wheel lifting mechanism is connected with the hydraulic jacking system through the linkage mechanism. The pallet boards are connected with the rear wheel lifting mechanism and the hydraulic jacking system correspondingly and are used for carrying goods. Two holes are formed in each pallet board. According to the novel multi-functional manual hydraulic carrier, when the goods are carried in a small space, the rear wheels acting as hampers are retracted to rectangular beams, the pallet boards which can be lifted normally can enter the small space to be lifted secondarily, and diversification of the carrying function is achieved. The state of the rear wheels can be restored through the half sleeve barrels, lifting of the four-support-wheel linkage mechanism is achieved, carrying capacity is higher, and stability is higher.
