The adjustable leveling adapter is a crucial transitional component used in large construction machinery such as tower cranes to connect the foundation to the tower body (or between different standard sections). Its primary function is to eliminate horizontal deviations caused by foundation construction errors or tower installation processes through its self-adjusting structure. This ensures the tower's verticality meets requirements, enhancing the installation precision and stability of the equipment. Below are its core features and details:
Structure and Adjustment Principle:
Equipped with adjustable bolt assemblies or wedge structures, the adapter allows fine-tuning of the horizontal height (typically within ±50mm, varying by model) by rotating adjustment bolts, adding/reducing shims, or moving wedge blocks. This compensates for uneven foundation surfaces or installation errors in embedded components.
Connection Function:
The lower end connects to embedded outriggers, concrete foundations, or base frames, while the upper end interfaces with the tower's standard sections. It accommodates various connection types (e.g., pin connections, bolted joints), ensuring seamless force transmission between the foundation and the tower.
Materials and Strength:
The main structure is typically welded from Q355B steel, with critical load-bearing components (e.g., adjustment bolts, pins) made from high-strength alloy materials (such as 40Cr) and heat-treated to ensure sufficient load capacity and deformation resistance, matching the tower crane's rated lifting capacity.
Applicable Scenarios:
Widely used in the foundation installation of large tower cranes, construction hoists, and other equipment, especially for tall structures with strict verticality requirements, such as TC7020, TC7530, and similar tower crane models.
By offering flexible adjustment capabilities, the adjustable leveling adapter reduces strict requirements for foundation construction precision while improving installation efficiency and safety. It is an essential component in modern construction machinery foundation connection systems.
