1. System for transporting a load along a transport route from an uploading engagement point to a downloading disengagement point, wherein the load is hoisted and kept suspended along the route, comprising:
a bridge;
a hoisting module hanging down from said bridge and operative for engaging, lifting, suspending, depressing/bringing down, and disengaging the load;
a haul mechanism comprising at least one of:
a bridge displacer operative for displacing said bridge; and
a trolley operative for travelling along said bridge, wherein said hoisting module hangs from said trolley; and
a resource optimizer for determining an optimal-resource consumption route from said uploading engagement point to said downloading disengagement point which is conducted by respective activation of said hoisting module and/or said haul mechanism, including determining respective parameters of acceleration, deceleration, and sway-restraint maneuvers along said optimal-resource consumption route, wherein said optimal-resource consumption route is segmented into at least one segment, wherein a respective segment safe-travel sway-span and a respective segment hand-over sway-span are predetermined for each of said at least one segment, and wherein each of said at least one segment comprises an initial acceleration section in which a dangling load is allowed to sway up to said respective segment safe-travel sway-span, and a final deceleration section, wherein sway of the dangling load is restrained at a latter part of the respective segment for reaching said respective segment hand-over sway-span at the end of said at least one segment, wherein said resource comprises at least one of:
time;
energy;
system-wear
any combination of said time, energy, and system-wear; and
any weighted combination of said time, energy, and system-wear,
wherein said resource optimizer is operative for:
determining segment minimum resource consumption routes by determining for each of said at least one segment, a segment minimum resource consumption route including determining respective parameters of acceleration, deceleration, and sway-restraint maneuvers along said at least one segment, per said respective segment safe-travel sway-span and said respective segment hand-over sway-span;
combining possible minimum resource consumption routes from said segment minimum resource consumption routes; and
selecting an optimal resource consuming route out of said possible minimum resource consuming routes,
and wherein transporting of the load from said uploading engagement point to said downloading disengagement point is conducted pursuant to said optimal resource consumption route including its respective determined parameters.
