- 1 3 - ABSTRACT THE INVENTION RELAIES TO A LIFTING INACHINERY OF TWO REEL DIFFERERITIAL TYPE FOR TWO 40 FECT CONTAINER SHORE CRANE, COMPTISING. A NIOTOR, AREDUCTOR AIND ITS HIGH SPEED BRAKE, REULS AND REEL BRAKOSI WHEICIN AT LEAST ONE MOTOR IS PROVIDED: A PLARICTARY DIFFERENTIAL REDUCTOR IS U,;CD AS 1HE RCDLICTOR CONNECTED TO THE RNOLOR OL11PUT END, THE PLANCTAR-@ DIFFERENTIAL REDUCTOR HAS A HIGH SPEED INPUT SHAFT, A LOW SPEED OUTPUT SHAFT AND A DIFFERENTIAL PROJECT SHAFT. THE HIGH SPEED INPUT SHAFT CONNECTS TO THE MOTOR OUTPUT SHAFT, AT LEAST ONE HIGH SPEED BRAKE IS PROVIDED ON THE HIGH SPEED INPUT SHALT; TWO I-OUR PROJECT ROPE RECLS CONNECT TO TWO LOW SPEED OUTPUT SHAFT: AT LENST ONE REEL BRA-C IS PROVIDED ON EACH REEL; AND THE LIFTING MACHINERY COMPRISES A DIFFERCRITIAL SHAFT BRAKE CONSISTING OF' AT LEAST DIFFERENTIAL SHAFT BRAKES PROVIDED ON LWO DIFFERENTIAL PROJECT SHAFT: THE REVOLUTION OF THE TWO DIFFERENTIAL PROJECT SHAFT OF THE PLANETARY DIFFERENTIAL REDUCTOR IS CONTROLLED BY THE TWO CLIFFCRUNTIAL SHAFT BRAKES SO THAT POWER OF THE PLANCLARY DIFFQRENTIAL REDUCTOR MAY BE DISTRIBUTED SO AS TO ACHLIELLC THE SYNCHRONOUS OPERATION OF TXVO HANGER TOOLS OR THE OPERATION OF SINGLE HANGER TOOL . MECTING THE LOADING, AND UNLOADING REQUIREMENT, INCREASING DIE LOADING AND UNLOADING EFFICIERIC), OF THE CONTAINER CRANE BY MORE THAN 60F I G . 1 X06@3@P
