The flexible KBK crane is a modular lightweight combined lifting equipment. The entire equipment is assembled using standardized universal components. It is mainly composed of track profiles, flexible hanging components, operating trolleys, lifting hoists, and electrical control components. The equipment can be suspended and installed on the overhead building beams, or it can be installed independently on the ground with a self-standing steel structure frame, eliminating the need for ground tracks to occupy the floor space of the workshop. It can be flexibly combined into various structural forms such as monorail conveying, single main beam, double main beam, etc. It is suitable for lifting working conditions of 125kg-2000kg light and medium tonnage stations. It is the mainstream equipment for high-frequency and short-distance material handling in assembly workshops and processing production lines. The tracks are made of high-strength cold-rolled steel or aluminum alloy profiles and are connected through spherical hinges and flexible hangers, which can absorb slight deformations of the factory structure, allow the track to swing slightly, support multiple path layouts of straight rails, curved rails, and branch tracks, and adapt to complex workshop equipment complex workshop layouts. The whole machine can be equipped with manual and electric chain hoists, supports manual‑handle control, and multiple control modes of wireless remote control, taking into account the installation of new factory buildings and the transformation and upgrading of old workshop production lines.

Core advantages

It adopts fully modular standard parts and bolt‑together assembly, no need for on-site welding, and the installation cycle is short. During the later production line adjustment, the track modules can be directly added, removed, and moved, making expansion and transformation convenient. The track profile is light in weight and requires lower load-bearing conditions for the upper part of the factory building. The flexible hinged structure reduces structural stress. The running trolley has small walking resistance and is easy to push manually, effectively reducing the operator's operator workload. The layout has a high degree of freedom and can realize curved and circular track layouts. It can bypass equipment obstacles inside the workshop and flexibly adapt to the flow direction of the assembly line. It does not occupy ground operation space, and material handling is completed in the air, retaining space for ground passage and equipment placement in the workshop, and optimizing the utilization of factory space. The parts are highly versatile, easy to maintain and replace in the future, and the overall comprehensive investment cost is controllable. It is suitable for high‑frequency continuous workstation operations, and the working level covers M4-M7, and can operate stably for a long time.
