Abstract
A buffer crane for supplementing a quay crane operation and formed to operate thereunder with a landing deck for supporting a multiple of cargo containers above dockside cargo transport operations and for moving cargo containers therebetween by means of a bridge crane mounted on framework rails which extend past the lateral edges of said landing deck.
Claims7
A buffer bridge crane for cargo container handling comprising
- an elevated platform forming a landing deck where containers can be landed on preselected landing positions the and temporarily stored by a quay crane when they are removed from shipboard or where containers picked off ground level transporters can be landed until they are picked up by the quay crane for transport to a ship, said platform being supported by transport wheels for independent all-direction movement, said buffer crane having a low profile whereby it can be positioned underneath said quay crane to receive cargo containers therefrom as well as from said container transporters and whereby said quay crane can extract containers therefrom and said buffer crane can deliver containers therefrom to said transporters, and
- an overhead cargo container handling bridge crane supported above said platform by framework integral thereto and movable to container deposition positions disposed on said landing deck and laterally beyond the edges thereof, said bridge crane having container lifting apparatus arranged to transfer containers between said landing deck and said transporters when they are parked alongside said platform at the lateral edges thereof.
A buffer crane for cargo container handling comprising
- an elevated platform forming a landing deck where containers can be landed on preselected landing positions and temporarily stored by a quay crane when they are removed from shipboard or where containers picked off ground level transporters can be landed until they are picked up by the quay crane for transport to a ship, said platform being supported by columns, pairs of which are interconnected at the lower ends thereof by sill beams which are supported by motorized transport wheels for independent all-direction movement of said buffer crane,
- an overhead cargo container handling bridge crane supported by framework disposed at least at the fore and aft edges of said platform whereby containers suspended by lifting apparatus from said bridge crane can be lowered between said fore and aft framework onto said landing positions disposed therebetween, said bridge crane spanning the length of said landing deck and formed to reciprocate laterally thereacross on rails mounted on said framework to positions beyond the lateral edges of said platform whereby containers suspended from said bridge crane by said lifting apparatus may be transferred between said landing deck and said ground level transporters when they are parked alongside the lateral edges of said platform, said bridge crane and container lifting apparatus being mounted on said framework rails at a level to pass above cargo containers deposited on said landing deck and remain below the supporting structure of any cargo container quay crane it is positioned under, position guides disposed at said preselected landing positions on said landing deck to receive and guide containers being lowered there onto,
- at least one service platform disposed below and proximate to said landing deck to permit workers to install and remove interbox connectors from cargo containers deposited on said landing deck,
- a multiple of access openings formed in said landing deck to permit workers to install or remove said interbox connectors which are secured to corners of cargo containers deposited on said landing positions through said openings, and
- an automated control system for at least partial operation of said bridge crane to position said cargo container lifting apparatus over said preselected landing positions on said landing deck and to move containers with coordinated motion.
