|Title:||TOWER CRANE CLIMBING FRAME DEVICE WITH CABLE|
A tower crane climbing frame device with a cable, comprising two parallel C-shaped beams (1). The C-shaped openings of the two C-shaped beams (1) are arranged oppositely and independent of each other; each C-shaped beam (1) consists of a primary beam (2) in the middle and two secondary beams (3) at the ends, and the secondary beams (3) are perpendicularly fixed at the ends of the inner side of the primary beam (2); a connecting member (4) is connected between two secondary beams of the same C-shaped beam (1); a connecting base (5) parallel to or coaxial with the secondary beam (3) and used for fixing to a support structure (9) is provided at each of the ends of the sides of the primary beams (2) away from each other; both the primary beams (2) and the secondary beams (3) are provided with propping devices (6) fastened to a main limb of a tower crane tower body (8). According to the tower crane climbing frame device with a cable, there is no linkage rod between the secondary beams on the same axis of two C-shaped beams, redundant restrictive linkage rods are omitted, the installation and removal, and transportation workload of a climbing frame is reduced, and materials are saved.
