Bridge erecting machine: bridge erecting machine is not only an important construction equipment for bridge erecting, but also a large-scale mechanical equipment. After installation and commissioning, passing through the hole is a step of beam erecting construction, which is also a very important step. Therefore, the bridge erecting machine needs to pay attention to many matters when passing through the hole. Some main matters are listed below for reference.
1. Attention should be paid to the specific conditions of the bridge, such as curve, vertical and horizontal slope and slope, which should be carefully observed and analyzed before passing through the hole. If necessary, actual measurement is needed.
2. In general, the span of the bridge erecting machine is large, and the expansion joints at both ends of the bridge are strong.
3. When going downhill, the front outrigger is long. In addition, it is necessary to pay attention that the telescopic cylinder should not extend too long out of the guide cylinder (the cylinder stroke should not extend too much).
4. When the bridge crane passes through the hole, the front carbonyl is generally slightly higher than the rear carbonyl, and attention should be paid to the completion of the hole, not to stop halfway. The front and middle track beams should be kept horizontal as far as possible. The front outrigger cushion sleeper should not be too close to the edge of the cap beam, leaving a certain space for the beam, and then it should be in the middle. The steel wire rope of the counterweight beam and the hoist must be tightened, but it cannot be lifted off the trolley. It is particularly noted that when going up or down the slope, as the rear support approaches the middle support, the tightness of the steel wire rope must be observed and the hoist adjusted. In short, the steel wire rope must be in a tightened state. When lifting the counterweight beam, it is easy to use the rear crane.
5. The front and rear crown block must be firmly fixed with the main beam, and the bad phenomena such as car sliding and sliding are not allowed. The front outrigger must be crossed and tightened with chain block. The span of the hole is: bridge span + 4m + expansion joint reservation.
In a word, it is very important for the bridge erecting machine to go through the hole when erecting the beam. We must follow the operating procedures and strictly control the safety matters. QJ 180t-40m bridge erecting machine. The bridge erecting machine is a kind of steel structure rail type precast beam hoisting and erection equipment with wide operation range, good performance, convenient operation and safe structure. In the process of erecting the side beam, the bridge erecting machine should be especially careful, the lifting should be stable, the beam should be accurately dropped, and it is not allowed to walk out of the suspended track. The product has the advantages of simple structure, convenient operation and maintenance, good safety and reliability, and can effectively reduce the potential safety hazard.China's low-cost bridge machine manufacturers sales, general gantry crane, crane photos
