Abstract (en)
[origin: JPH10279281A] PROBLEM TO BE SOLVED: To provide a small and simpler occupation space and facilitate and ensure the arrangement, pulling up work, and transportation of a crane. SOLUTION: At least one front shroud 13 brings a front part of a rotary base 3 in contact with a rear part 20 of a lower outer element 6 of an telescopic support 5 continuously and connects them. Two rear shrouds 14 bring an intermediate point 23 of the rotary base 3 in contact with the rear part 20 of the element 6 of the support continuously and connect them. A mechanization unit consisting of a double action jack 15 and connection bar systems 16, 17 connects the front shroud 13 with the element 6 of the support and controls the relative movement of the element of a device 12. Consequently, this support pulling up device can be applied to a tower crane which is assembled automatically, consists of two or three elements 6, 7, 8, and is of telescopic support 5 type.
