The invention discloses a wooden slab processing and transporting device which comprises an RIAATL electric control cabinet and an operating table. A power line is arranged on one side of the RIAATL electric control cabinet and electrically connected with the RIAATL electric control cabinet. A transverse plate is arranged on one side of one of supporting plates and fixedly connected with the one supporting plate through a screw. A control panel and a shift knob are arranged at the top of the transverse plate. According to the wooden slab processing and transporting device, rubber pads are mounted on the surfaces of long rollers, thus, the collision damage degrees of wooden slabs and the long rollers can be decreased, and the material integrity is protected; in addition, hydraulic rods aremounted at the tops of supporting legs, and the heights of the hydraulic rods can be adjusted when wood needs to be transported to a high position; meanwhile, a scale rod, a TWSA displacement sensor and an alertor are mounted on one side of the operating table, the alertor makes a sound when the heights of the wooden slabs are found to have large differences, and the wooden slab processing and transporting device has wide application prospects in the future.
