Description

Double entry tower machine fish plate landing leg structure

Technical Field

Background

In the tower crane technical service industry, the most common tower crane foundation is special for a special machine, the pre-embedded support legs are in an independent specification during foundation construction, and under the condition that tower crane resources are in short supply, if the foundation is buried well, the construction period is easily delayed seriously under the condition that the corresponding tower crane cannot supply goods on a time node for installing the tower crane. Or in view of cost, the tower crane has a large tonnage which is needed by the heavier structural member in the early stage, but the tonnage of the structural member to be hoisted is small in the middle and later stages, and under the condition of long construction period, if the original large-tonnage tower crane is still used for hoisting continuously, the hoisting cost is also greatly wasted. In another case, in some plants, the limitation is very obvious if a single leg is embedded as usual under the condition that a tower crane needs to be used for hoisting operation all year round or different types of tower cranes need to be replaced in the process because of cost problems or annual use requirements. If a foundation is made again for installing another type of tower crane, the cost and the construction period are both very waste.
