Title: NON-CLOSED TOWER CRANE CLIMBING FRAME DEVICE
Abstract:
A non-closed tower crane climbing frame device, comprising two C-shaped beams (1) arranged symmetrically. 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; the secondary beams (3) are perpendicularly fixed at the ends of the inner side of the primary beam (2), and are fastened by means of haunch plates (4); a connecting base (5) parallel to or coaxial with the secondary beam (3) and used for fixing to a support structure (8) 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 body (7) of the tower crane. The non-closed tower crane climbing frame device omits redundant restrictive linkage rods, reduces the installation, removal, and transportation workloads of a climbing frame, and saves the materials.
