20 ton Knuckle boom truck mounted crane

F460KC-05 ​​20-Ton Hydraulic Knuckle Boom Crane

Limited space at construction sites often restricts the maneuverability of conventional lifting equipment—a common pain point in the industry. Furthermore, customers frequently face limitations due to single-function equipment, which struggles to handle both heavy lifting and aerial work requirements. The F460KC-05, a 20-ton knuckle boom crane, is specifically designed to address these challenges. Featuring a robust hydraulic structure for heavy-duty operations, it is well-suited for diverse applications—including municipal projects, factory operations, and material handling. It can be equipped with various attachments to expand its operational capabilities, offering a distinct alternative to telescopic boom cranes. This model boasts a maximum lifting moment of 45 ton-meters, supports continuous 360° rotation, and offers an operating radius of 2.3m to 10.3m. Optional accessories—such as remote controls, man baskets, and grapples—enable the crane to handle complex tasks, including both lifting and aerial operations. For offshore projects, we offer specialized ship-mounted telescopic and knuckle boom cranes; for handling timber or bulk materials, our dedicated grapple machines and forestry cranes are also available.

1. Product Features: Compact design with a small footprint when folded; a smooth-operating hydraulic system with high reliability under heavy loads; 360° unrestricted rotation; and a wide range of optional attachments for multi-purpose utility.

2. Tips: Always verify the load chart before operation and ensure that all lifting tasks are performed strictly within the 2.3m–10.3m radius. When using a grapple, ensure that the hydraulic flow rate is compatible with the attachment’s specifications.

FAQ

Q: Can this knuckle boom crane be fitted with a grapple for handling timber?

A: Yes, it can be equipped with a grapple for such tasks—functioning similarly to a dedicated forestry/timber crane. Please inform us of your specific operational requirements when placing your order so that we can configure the hydraulic circuits accordingly.

Q: What are the key focus areas for routine maintenance?

A: Regularly inspect the quality of the hydraulic oil, the condition of the seals, and the tightness of the slewing bearing. Before each operation, verify that the limit switches and remote control signals are functioning correctly to minimize the risk of hydraulic leaks.

Q: What after-sales support is provided?

A: We offer a warranty on core components of the main unit, along with remote technical guidance. Wear parts can be supplied separately, and for overseas orders, we can coordinate the shipment of spare parts.

Q: How should I choose between this and a telescopic boom crane?

A: A knuckle boom crane is the preferred choice for confined spaces or operations requiring obstacle avoidance, while a telescopic boom crane is better suited for open areas where a greater vertical lifting height is needed.

Q: Are parts interchangeable between a marine knuckle boom crane and this model?

A: Because these units have different protection ratings for their respective operating environments, direct interchangeability of parts is not recommended. Marine-grade models feature specialized anti-corrosion and waterproof designs; therefore, you should specifically select a ship-mounted telescopic boom crane or a marine knuckle boom crane for maritime applications.
