Climbing Cranes
The climbing tower cranes don’t need a ground-bound foundation but rather “climb up” the structure’s exterior concrete walls while the building is still in the process of construction. Using designated folding steel beams with flexible joints, the cranes are leveraged on the building’s exterior walls while leaving the building envelope fully intact. Unlike working in the traditional configuration, which requires the use of many anchors and ties, which stop the work with the crane, climbing cranes shortens execution times and saves costs.
Climbing Cranes – Advantages
A climbing crane allows construction to proceed quickly, continuously, and precisely—especially in urban and dense projects.
Key Advantages:
Parallel work on frame and finishing—the crane climbs with the structure, allowing finishing work to begin on the lower floors while the building frame continues to rise.
Significant space savings—a climbing crane requires minimal land space and is particularly suitable for dense sites, redevelopment, and existing structures.
Shortening project schedules—continuous work without repeated set-ups and dismantling leads to earlier completion of phases and reduced logistical delays.
Skyline Climbing Systems
Skyline has developed and manufactured two climbing systems that refine and streamline the world’s standard method for climbing cranes.
Spider Climbing system
A “spider” climbing system is built as a single unit that folds and deploys quickly. The system “adjustable chairs” are anchored to the core wall, an inner security room wall, or the external columns of the building and can be connected and disconnected quickly.
The use of this system is intended for construction in which the core wall or security room is located on the building’s interior, and beams need to be sent to connect to it.
"Cantilever Beam"
A “cantilever beam” climbing system is used when the core wall or security room is located on the building’s interior, and beams need to be sent to connect to it. The system can be connected and disconnected quickly, using dedicated steel beams that are attached to the inner building’s walls.
FAQ
Skyline’s climbing cranes are mounted on the building envelope using two climbing frames and are not connected to the ground. A climbing crane allows finishing work to begin and end on all the floors below, including the envelope, thereby saving time and costs.
The “Spider” climbing system – built as a single unit, folds and deploys quickly, with “adjustable chairs” anchored to the core wall, an inner security room wall, or the external columns of the building.
The “cantilever beam” climbing system can be quickly disassembled and assembled using steel beams and is suitable for structures where the core wall is inside the building and not in the envelope.
Both systems are designed to shorten execution times and save costs during construction.
