Problems solved by technology
[0002] The lifting device is the main component in the field of tower cranes. The lifting device generally includes upper and lower layers. The upper layer is supported by the top bracket. The upper layer is generally equipped with a resistance box and an operation box. Generally, the resistance box and the operation box will be arranged on both sides of the top bracket. , a skylight is opened in the middle, and the middle of the top bracket is supported by two main beams. The structure of the two main beams cannot be changed too much. At most, some angles should be fine-tuned to form a figure-eight, but the opening size of the skylight still cannot be changed, and After the skylight is opened between the two main girders, the operating space on the upper floor is relatively limited

The invention relates to the technical field of top support, in particular to a top bracket of a lifting device. A skylight opening of the top bracket is increased, so that more objects can be stacked; and the top bracket is reasonable in structural setting, and increases a top operation space. The top bracket comprises an outer frame, wherein an upper top plate is mounted on the outer frame; two main beams are mounted in the middle of the upper top plate; and a distance between the two main beams is smaller than a distance from the main beams to the edges of the outer frames at sides of the main beams. The top bracket is characterized in that at sides of the two main beams, the skylight opening is formed in the upper top plate, and the skylight opening is equipped with a skylight through a hinge base; and at the other sides of the two main beams, a reinforcing rib is mounted on the upper top plate, the two main beams are connected through a transverse rib, and a suspension arm base is mounted on the transverse rib.
