The utility model provides a landing leg assembly and a pump truck, the landing leg assembly comprises a vertical landing leg and an auxiliary landing leg, and the auxiliary landing leg is fixedly installed on a landing leg sleeve of the vertical landing leg and comprises a lifting supporting rod capable of vertically lifting. The supporting leg assembly is mainly applied to supporting work of the engineering machinery, and generally, a plurality of supporting leg assemblies are installed around the engineering machinery needing to be supported, so that the engineering machinery is supported at multiple points together. The vertical supporting legs are main supporting pieces of the supporting leg assembly, and the auxiliary supporting legs are arranged on the outer sides of the vertical supporting legs, so that when any vertical supporting leg is in a suspended state, the auxiliary supporting legs are lowered in time to replace the failed vertical supporting legs to play a supporting role, and therefore the s
