Abstract

1,012,509. Erecting overhead travelling cranes. LAWRENCE - COLEBROOK (CONSTRUCTION EQUIPMENT) CO. Ltd. Aug. 31, 1964 [Nov. 13, 1963], No. 44889/63. Heading B8B. To erect a portal crane, wheeled carriages 1, Fig. 3, are placed as shown and columns 4 each containing two sections 5 of mast are supported on cribs 9. Legs 2 are pivotally attached to the carriages 1 and the columns 4 and a mast head 6 is placed on top of each mast. A bridge 7, Fig. 1, complete with cross, is attached to the mast heads 6. The wheeled carriages 1 are drawn together by winches 8 (not shown) until the columns are raised as high as possible. After securing the legs to the columns the erection winches are used to raise the mast sections inside the columns. Sections are added to the bottoms of the columns until the desired height is reached. The masts are guided by rollers and rest on girders between lifts.
