Generally, the sleepers are laid at certain intervals under the entire transverse track device, with 2-4 layers, and are laid in a crisscross pattern. Therefore, a large number of sleepers need to be transported, and each time the lower sleepers must be manually stacked one by one on the transverse track device, and then transported to the top of the next span of the cap beam along with the legs, which is time-consuming and labor-intensive. Not only that, when re-erecting the sleeper frame, it is necessary to manually measure in advance and adjust the height of the sleepers according to the horizontal slope and flatness of the upper surface of the cap beam to ensure that the transverse track device and the upper surface of the cap beam are compacted before the next operation can be carried out. This process will be subject to errors in the human eye, resulting in failure to compact or uneven transverse track device, causing the bridge erection machine to roll over, and the process is time-consuming and labor-intensive.
