    In addition to the universal requirements for handling (lifting and transport) machines (HM), HM for dangerous goods (hot molten metal, containers with chemicals, explosives, etc.) must also meet a number of special requirements. One of these requirements is the drive of the hoisting mechanism with two motors, to ensure in case one of them fails.
    The article discusses a reducer for the hoisting mechanism of an overhead crane for dangerous goods with an embedded planetary gear train, allowing both motors to operate at full power (and without overload) in both regular and emergency (in failure) mode. The different modes of work of the mechanism are considered (with both motors and with each one separately). An analysis of the possible kinematic schemes of the planetary gear train is made. The necessary kinematic calculations have been made to select the most suitable variant of the planetary gear train.

    The article reviews the requirements for the lifting mechanisms of cranes according to various regulations concerning dangerous goods. Particular attention is paid to these requirements regarding gear trains. Some design solutions for providing microspeed as well as for twin-motor drive are discussed. These arrangements are suitable for both lifting and travel mechanisms. A kinematic analysis was made and recommendations were given to the designers.
