Unlike traditional overhead cranes, the KBK system does not rely on the factory roof for support. Instead, it forms an independent running track by suspending aluminum alloy or steel rails beneath the building structure. Electric chain hoists are suspended below the rails to facilitate horizontal material transport and vertical lifting.
The core advantage of the KBK system lies in its “flexibility.” The entire system consists of standardized components—straight track sections, curved track sections, track turnouts, suspension assemblies, and chain hoists—which can be freely combined and disassembled according to the workshop layout. This means that when production lines are adjusted, workshops are renovated, or production capacity is expanded, the KBK track can be reconfigured without altering the building structure. Compared to fixed overhead cranes, the KBK system requires a lower initial investment and offers greater flexibility for adjustments.
The KBK systems manufactured by Yangyumech Machinery cover light-duty applications ranging from 0.5 to 5 tons. The components are compatible with mainstream European standards and can be paired with chain hoists from brands such as Demag and Konecranes. We also offer complete KBK track and suspension systems as standalone solutions.

FAQ
The maximum single-span length for KBK aluminum alloy tracks is 8–10 meters (depending on the load and suspension spacing). Steel tracks can reach a single-span length of 12–15 meters. If the single-span limit is exceeded, intermediate suspension points must be installed, or multiple track sections can be connected using track switches to form complex paths. Yangyumech Machinery engineers will provide specific span design solutions.
Yes. The KBK system offers 90-degree curved track sections, cross-over couplers, and T-shaped couplers, which can be combined horizontally and vertically to form complex paths covering multiple workstations. However, the turning radius must meet the minimum radius requirement (typically ≥600 mm), subject to actual load calculations.
The standard KBK chain hoist has a lifting height of 12–24 meters (depending on the model). For heights exceeding 12 meters, we recommend using a wire rope hoist instead of a chain hoist to minimize the impact of the chain’s dead weight on the payload.
No major modifications are required. The KBK system is connected to the building’s steel structure (steel beams, concrete slabs) using expansion bolts or welded brackets. Prior to installation, Yangyumech Machinery engineers will assess the load-bearing capacity of the building structure to ensure safety. If the building structure lacks sufficient load-bearing capacity, a custom load-bearing beam solution can be designed.
The KBK (single-beam) system features an aluminum alloy or steel monorail, with the hoist suspended directly below the track. It is suitable for light loads of ≤1 ton. The KBK-D (double-beam) system uses a main beam composed of two parallel tracks, with the hoist running between them. This provides more even load distribution, making it suitable for heavier loads of 1–5 tons and ensuring smoother operation at workstations.
Yes. Yangyumech Machinery’s KBK rails and suspension systems are compatible with brands such as Demag and Konecranes, allowing customers to purchase hoists from other suppliers for use with the system. Of course, Yangyumech Machinery can also supply matching chain hoists, offering a more competitive overall quote.
