Problems solved by technology
[0002] Conventional segmental box girders are set up on a single line, and the bridge erecting machine is moved longitudinally one by one to construct the span. Hoisting to the right side of the bridge, or reinstalling the bridge erecting machine on the right side of the bridge, because the bridge erecting machine is too large, this will greatly increase the construction period and cost

The invention discloses a traversing luffing method of a large-sized bridge erecting machine. The bridge erecting machine is slidably erected on a cross beam through middle supporting legs. The traversing luffing method comprises the following steps: 1, sliding the cross beam from the left side of a bridge to the right side of the bridge by using a steel rail. By the traversing luffing method, operation is convenient, the cost is low, the bridge erecting machine is not required to be hoisted, redetached and remounted, slippage of the cross beam in position in the case of no lifting equipment is achieved, and quick and convenient traversing luffing of the bridge erecting machine is achieved.
Description
technical field [0001] The invention relates to the field of bridge erecting machine margins. More specifically, the present invention relates to a large-scale bridge-erecting machine traverse amplitude-changing method. Background technique [0002] Conventional segmental box girders are set up as a single line, and the bridge erecting machine is moved longitudinally one by one to construct the span. Hoisting to the right side of the bridge, or reinstalling the bridge erecting machine on the right side of the bridge, because the bridge erecting machine is too large, this will greatly increase the construction period and cost. Contents of the invention [0003] The invention provides a method for lateral movement and variable amplitude of a large-scale bridge-erecting machine, which does not need to be hoisted or reassembled, can realize fast and convenient lateral movement and amplitude-changing of the bridge-erecting machine, is easy to operate, and has low cost.
