During the chimney wall construction process, the hydraulic platform lifting system and the tripod mold turning system have a very high utilization rate of construction elevators, such as vertical transportation of concrete, steel bars and miscellaneous materials, and up and down transfer of construction personnel. Since the supporting construction elevators have very high power, more resources will be consumed after frequent use, especially when transporting miscellaneous materials, which will cause serious waste of resources.

[0003] In view of the above situation, a small lifting equipment is generally installed on the technology of a matching large-scale elevator. The prior art discloses a lifting device for lifting a truss, which includes a bracket, a main support member and a secondary support member are fixedly connected to the bracket, the secondary support member is close to the edge of the bracket, and the main support member is far away from the secondary support member, a support rod is fixedly connected to the secondary support member, and a fixing member that supports and fixes the support rod is fixedly connected to the main support member. When the bracket is erected on the ground, one end of the support rod away from the secondary support member extends obliquely upward, and the projection of the end of the support rod away from the secondary support member on the ground is outside the projection area of ​​the bracket on the ground. A moving component is provided at the bottom of the bracket, a lifting component is provided on the support rod, and a driving component for driving the lifting component to operate is provided on the bracket.

[0004] With regard to the above-mentioned related technologies, in order to reduce the interference of the material shape on the convenience of lifting, the bracket is generally installed at the edge of the chimney wall construction platform. After the bracket is connected and fixed to the chimney wall construction platform, the vertical movement area where the hook is located is fixed. After the material is lifted by the hook, the construction personnel are required to move the position of the material horizontally through a hook rod or other means to make it fall on the chimney wall construction platform, which increases the labor intensity of the operator.
