The invention discloses a novel shear fork truck which comprises a frame, a working platform is arranged above the frame, the working platform is installed on the frame through a shear fork frame, a lifting hydraulic cylinder is installed on the shear fork frame, the novel shear fork truck comprises a hydraulic mechanism, the hydraulic mechanism is installed on the frame and connected with the lifting hydraulic cylinder, and the lifting hydraulic cylinder is connected with the hydraulic mechanism. The hydraulic mechanism comprises an oil tank, a hydraulic pump, a motor and an oil return filter, the oil tank is used for storing hydraulic oil, the oil inlet end of the hydraulic pump is communicated with the oil tank, the oil outlet end of the hydraulic pump is communicated with the oil inlet end of the lifting hydraulic cylinder, the motor is installed on the oil tank and is in transmission connection with the hydraulic pump, and the oil return filter is arranged on the oil tank. And the oil return filter is arranged on the oil tank. Hydraulic oil is supplied into the lifting hydraulic cylinder through the hydraulic pump, so that extension and retraction of the lifting hydraulic pump are directly controlled, arrangement of a hydraulic control valve is omitted, and the efficiency of a hydraulic system is improved.
