Definitions

  • ABSTRACT Described herein is equipment comprising a crane and a cargo container spreader combination wherein the spreader'is constructed as a repository for a self sufficient portable power unit adapted for quick connection with power consuming service mechanisms of the spreader.
  • the power unit is equipped with UHF radioactuated controls in the power transmission connections between the power generating facilities of the unit and the power consuming service facilities of the spreader.
  • the crane is equipped with UHF radio transmission apparatus for radio projection of a sufficient variety of signals to effect the various radio controlled functions of the spreader.
  • Typical functions to be so controlled include operation of a latch system for locking the spreader to a container, movement of a plurality of corner guides into and out of operable position which in lower operable position assure registry of a spreader with a container, operation of mechanism for expanding and contracting the length of the spreader, operation of spreader level adjusting mechanism, and actuation of grappler arms.
  • power must be supplied to the spreader to operate any safetyrelated features such as signal lights or other warning devices.
  • the power for controlling the service devices mounted on the spreader is electrical, even though final operation is performed hydraulically through various hydraulic motors deriving power from an electrically driven hydraulic pump-and reservoir system mounted on the spreader.
  • the electrical line circuits for any transmission of power or control signals to the spreader are incorporated in a single multiple conductor cable extending from the spreader in coextensive relation with any supporting cable or other structure by which the spreader is supported from the crane to an energy source connected with the crane. All signal circuits necessarily extend into control panel at the operator's cab.
  • the crane must be capable of suspending the spreader from its boom or other structure defining the upper limit for vertically positioning the spreader a height of a hundred feet or more.
  • the length of the cable or umbilical cord to the spreader is of sufficient length to accommodate maximum vertical spacing of the spreader from the point of cable suspension.
  • Another quite important object is the provision of a self sufficient portable power unit capable of being temporarily placed on a skeleton type spreader to furnish any type of power requirement needed to accomplish any of the functions for which the spreader is designed.
  • interchangeable power units are to be provided which permit one or more substitute power units to be available for use whereby a power unit may be withdrawn from service for maintenance or other purposes, and further, the provision of portable power units which are transferable from spreader to spreader will avoid the duplication of integral cable power supplied facilities on each spreader of types heretofore constructed.
  • the present invention resides in the provision of a crane and spreader combination for handling cargo containers comprising a spreader lacking the usual cable supplied power facilities, a portable self sufficient power unit having power generating and transmitting facilities such as electric lines, hydraulic lines, air lines, etc., with quick-disconnect fittings adapted to mate with corresponding fittings of the spreader.
