Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has:
the utility model discloses landing leg and back landing leg before loop wheel machine backup pad front end and rear end set up the drum-type, when hoist and mount, landing leg and back landing leg before the drum-type are as the landing leg of loop wheel machine, increase the stability of loop wheel machine. When the crawler crane is transported, the roller type front supporting legs can be used as auxiliary wheels for crossing obstacles, so that the trafficability of the crawler crane is greatly improved. The push pedal that the back landing leg was equipped with can play the effect of leveling ground, shovel soil at the crawler crane in-process of traveling, if meet the place that the slope is great, put down the push pedal and can use as the brake. The utility model has the advantages of reasonable design, convenient to use, landing leg and back landing leg have multiple use respectively before the drum-type, have increased the function of crawler crane.
