Construction method for strengthening track crane
The invention provides a construction method for strengthening a track crane. The construction method comprises the following steps: firstly fitting up welding roadbed boxes in a workshop by using hot rolled section steel, then paving the roadbed boxes in place at a construction site through a vehicle crane, and finally assembling the track crane by using the vehicle crane; the step of paving the roadbed boxes comprises the following steps: firstly mounting a main engine of the track crane, then mounting tracks on two sides, mounting a balance weight block, mounting a rod, finally threading a steel rope and mounting a lifting hook. After the track crane is completed, the lifting operation can be officially started after an acceptance check is qualified, the track crane runs on the roadbed boxes during the lifting operation of the track crane, and the track crane can lift a roadbed box at the rear part of the track crane to the front part of the track crane, so that long-distance forward running operation is completed; according to the construction method for strengthening the track crane, the length of a roadbed box is at least larger than a distance between supports of a girder through paving the roadbed boxes, so that weight of the roadbed boxes and the weight of the track crane are applied to the supports of the girder; besides according to the track crane, the roadbed boxes can be paved on a running route of the track crane, so that the paving time is shortened, and the construction progress is accelerated.
