The invention discloses a monorail crane turnout junction which is highly efficient, safe and reliable. The monorail crane turnout junction of the invention comprises a top plate, monorails and a camping rail. One end of the two parallel monorails is in butt joint and coordination with the movable end of the camping rail; baffle plates are respectively arranged at the ends of the two monorails; acamping rail hinged end is hinged on the top plate and is in butt joint and coordination with a uniseriate monorail end; a positioning shaft is arranged on the movable end of the camping rail; two positioning cylinders are both fixed on the top plate; a positioning fork is arranged on the piston rod of a telescopic cylinder; the positioning fork is in plug-in coordination with the positioning cylinders; and an oscillating cylinder is in rotary coordination with the top plate. In the invention, the structure which is characterized in that the baffle plates, the positioning cylinders, the positioning shaft and the positioning fork are matched is adopted, so that the camping rail is locked and the safety is greatly improved. The operation of the turnout junction can be achieved by controlling the oscillating cylinder and the telescopic cylinder and no manual operation is needed, as a result, the operating efficiency is high and when remote control is applied, the operating efficiency is even higher.
