Disclosed is a construction method for a cantilever beam on a central pier. A scaled model of the cantilever beam on the central pier is established and tested to obtain the stress distribution regularities of the cantilever beam according to test data and analysis results of the scaled model, so as to find out week parts of the cantilever beam, and thus the optimization design can be performed to make the cantilever beam reasonably carry the load and improve the materials with a higher utilization ratio. The wheeled stand support used in the present application has a high turnover rate and it is easy and convenient to dismantle and assemble the wheeled stand support. A height of the cantilever beam mold can be adjusted by a hydraulic cylinder.

A lifter assembly includes a base having a top and a bottom surface. Connectors are attached to the base extending outwardly from the bottom surface. Each of the connectors includes at least one rail wheel rotatably attached thereto. The base includes traveling wheels rotatably attached thereto. A post is attached to the base extending outwardly from the top surface to a distal end. An arm is disposed on the distal end, rotatably attached to the post, extending outwardly to a terminal end. A support is movably attached to the arm and extends outwardly to a support end. A trolley is slidably disposed on the arm and movable along the arm between the terminal end and the post. Each of the traveling wheels includes a leg pivotably attached to the base connecting the traveling wheel to the base and move the traveling wheel between a transport and a storage position.
