The invention relates to the technical field of building machines, in particular to a hanging basket suspension gear. The hanging basket suspension gear is simple in structure, stable and reliable and comprises two supports. The two supports are connected through a cross beam. The cross beam is supported on a vertical rod. The vertical rod is fixed to the side of a wall. One support is fixed to the upper end of the wall. The two supports are each provided with a transverse guide sleeve. An adjusting rod is arranged in the manner of penetrating the two transverse guide sleeves. A vertical upper bracket is mounted on the support fixed to the upper end of the wall, and a connecting plate is mounted on the other support. One side of the top of the vertical upper bracket is connected with the end, on the side, of the adjusting rod through a first pull rope. A rope clamp is mounted at the lower end of the end of the adjusting rod. The other side of the vertical upper bracket is connected with the connecting plate through a second pull rope. A lifting lug is mounted at the position, at the lower end of the vertical rod, of the wall and connected with the end of the cross beam through a third pull rope.
