The KBK double girder overhead suspension crane is a light-duty lifting equipment designed based on the modular KBK track system. It consists of two parallel main KBK track girders, which are suspended and installed under the steel structure of the factory building roof. The hoisting mechanism is suspended on the trolley frame between the two main girders to realize vertical material handling.
Main Structure and Working Principle of KBK Suspension Crane
KBK Track System: Adopts high-strength cold-rolled section steel or aluminum alloy, supporting the combination of straight and curved sections.
Double Girder Structure: Enhances the overall rigidity and load-bearing capacity.
Electric Hoist System: Equipped with optional chain hoists or fiber rope hoists for precise lifting.
Traveling Trolley: Moves smoothly along the track, with manual or electric drive available.
Electric Control System: Supports frequency conversion control for smooth starting and precise positioning.
The working principle is that the electric hoist travels between the double girder to achieve vertical lifting, while the entire crane moves horizontally along the rail system, enabling material handling in three-dimensional space.
Product Advantages of KBK Double Girder Suspension Crane
The double girder structure features stronger load-bearing capacity compared with single-girder systems, making it suitable for medium and high load handling requirements.
The KBK system adopts standard modular combination, enabling flexible design, expansion or renovation according to workshop layout.
The suspended installation method does not occupy ground space, making it ideal for space-constrained or clean environments.
Combined with frequency conversion control technology, it achieves millimeter-level positioning, suitable for precision manufacturing industries.
All components (tracks, connectors, trolleys, lifting points, etc.) are standardized products connected by bolts without welding required.

FAQ
Q: What is the difference between a KBK double girder suspension crane and a single girder one?
A: The double girder structure provides higher load-bearing capacity and stability, suitable for working conditions with heavier loads and higher precision requirements, while the single girder type is more suitable for light-duty handling.
Q: Do your KBK cranes support non-standard customization?
A: Yes. We can conduct personalized design according to the customer's factory building structure, production process and load requirements, including track layout, span, lifting height and other parameters.
Q: Is the installation complicated?
A: No, it is not. The KBK system adopts a modular design for quick installation, and generally can be deployed in a short period of time.
Q: Is the later maintenance cost high?
A: The maintenance cost is low. The structure is simple, standardized components are easy to replace, and the system operates stably with a low failure rate.
