Durable Components
High-Quality Materials: The flat-top tower crane is made from the highest quality durable components on the market, capable of withstanding harsh environments and demanding tasks
Ease of Assembly and Disassembly
Lower Equipment Requirements: The absence of a tower head reduces the unit mass and installation height, lowering the maximum installation height by over 10m compared to similar cranes with tower heads. This significantly reduces the lifting capacity required for assembly and disassembly equipment.
Suitable for Group Tower Operations
Reduced Overall Height: Without the tower head, the overall height for group tower operations is greatly reduced, resulting in less installation time and lower requirements for installation equipment. Smaller counterweights and smaller tower body sections and base frames are also advantages.
Ideal for Height-Sensitive Constructions
Increased Effective Height: The lack of a tower head significantly increases the effective height of the hook, making it highly suitable for constructions with special height requirements such as airport renovations, constructions near airports, tunnel interiors, factory interiors, and under high-voltage lines.
Adaptable Amplitude Changes
Easy Boom Adjustments: The unique connection method of the jib sections and the absence of a tower head and guy wires make it easy to add or remove boom sections in the air without needing to dismantle the entire boom. This is particularly useful when amplitude changes are required during construction.
Convenient for Limited Site Conditions
Optimal Solution: When site conditions restrict access for truck-mounted cranes, using a flat-top crane becomes the best solution. Its unique boom connection allows for section-by-section assembly and disassembly in the air, enabling direct loading and unloading of boom sections from transport vehicles if needed.
Long Boom Lifespan and Safety
Stress-Free Operation: Flat-top cranes operate more smoothly, especially during slewing or emergency braking, as the boom only experiences downward loads. In contrast, conventional cranes have additional horizontal and upward forces due to guy wires, leading to fatigue damage and weld cracks. The constant stress changes typical in conventional cranes are absent in flat-top cranes, greatly extending boom lifespan and enhancing safety.
High Applicability and Utilization Rate
Modular Boom Design: The boom's design facilitates modularity, which is crucial. For manufacturers, this reduces design and manufacturing costs, thereby lowering the price of flat-top cranes. For users, it maximizes the flexibility and adaptability of the boom.
