Abstract:
A rail-borne handling machine for handling containers and bulk materials in seaports and inland harbors, comprising:a framework for carrying load bearing means and including gantry supports arranged on the framework; rail-based traveling gears connected to said gantry supports of said framework by articulated connections for supporting said framework on rails; balancers connected to said gantry supports by said articulated connections such that said balancers are pivotal about a substantially horizontal axis, wherein said rail-based traveling gears are connected to said gantry supports by said balancers; at least four steerable tire-based traveling gears connected to said framework by said balancers, said at least four steerable tire-based traveling gears being symmetrical to a longitudinal axis and a transverse axis of said handling machine, wherein said handling machine is maneuverable by said at least four steerable tire-based traveling gears when said rail-based traveling gears are raised from the rails; and stops arranged on said framework, wherein ends of said balancers that are distal from said each of said at least four steerable tire-based traveling gears are positioned against said stops for absorbing a supporting moment when said handling machine is supported by said at least four steerable tire-based traveling gears.
