ABSTRACT:
A system is disclosed for transporting a lighter 136 from a floating position adjacent the stern 130 of ship 101 to a storage position in the cargo hold 138 of said ship, and for transporting lighter 136 from said storage position to said floating position. The system includes crane 102 which is adapted for fore and aft travel along spaced rails 104 and 106 which extend longitudinally along opposite sides of ship 101 and for hoisting lighter 136, and load frame 172 which is suspended by crane 102 and adapted for attachment to lighter 136. Vertically extendable and retractable load frame guide members 108, 110, 112 and 114 depend from crane 102. Removable aft guide members 118 and 120 are mountable on cantilevered beams 122 and 124. Removable fore guide members 126 and 128 are mountable on stern 130. Guide members 118 and 120 are adapted for being positioned below and coaxially aligned with guide members 108 and 110. Guide members 126 and 128 are adapted for being positioned below and coaxially with guide members 112 and 114. Fixed fore guide members 132 and 134 are mounted on stern 130 and adapted for being positioned below and coaxially aligned with guide members 126 and 128. Guide members 108, 110, 112, 114, 118, 120, 126, 128, 132 and 134 are adapted for retaining the swinging movement of load frame 172 when lighter 136 is hoisted by crane 102.
