Abstract

The invention discloses a high-stability beam lifter. The high-stability beam lifter comprises bases, wherein first movable wheels are fixed at the bottoms of two groups of the bases, and supporting legs are mounted on the tops of the first movable wheels; first main beams are arranged on the tops of the supporting legs, and limiting blocks are fixed on the tops of the first main beams; and a second main beam is arranged between the two groups of the first main beams. According to the high-stability beam lifter, the first main beam and the second main beam are provided and are connected through the connecting rod, the second main beam can be jacked up through the relative movement of the first moving wheel at the bottom of the first main beam, the second main beam is overlapped on the topof the first main beam, the second main beam is limited through the limiting block, the overall thickness of the main beams is increased, thus the weighing capacity and the stability of the device areimproved, meanwhile, the overall width of the device can be reduced, the occupied area of the device is reduced, and as a result, the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of beam lifting machines, in particular to a beam lifting machine with high stability. Background technique [0002] The beam lifting machine is a kind of gantry crane specially designed for bridge construction. The beam lifting machine is mainly composed of assembled main beams, outriggers, cranes, etc. The components are connected by pin shafts and high-strength bolts, which are easy to disassemble and transport. ;Compared with ordinary gantry cranes, it is convenient and quick to install, economical and practical, and is suitable for road and bridge construction units that often flow; [0003] However, the length and bearing capacity of the main beam are fixed during the use of the existing beam lifting machine, and the main beam cannot be superimposed to increase the thickness of the main beam to improve the beam lifting capacity of the device and the stability of lifting heavy objects, and the usability...
