Underslung KBK multi-rail parallel flexible crane

Structural Composition

Suspension track:Multi-layered red KBK enclosed steel track, arranged in parallel, standard sections can be spliced together to extend indefinitely.

Hanging connectors:High-strength hangers and clamps fix the track to the underside of the roof truss/ceiling structure, with adjustable height.

Trolley:Built-in low-friction rollers drive the hoist along the track, making it easy to move.

Electric chain hoist: Orange body, equipped with black lifting chain and hook, responsible for vertical lifting.

Hook assembly:Forged hook with anti-slip latch, ensuring smooth chain loading and unloading.

Power supply system: Flat cable/sliding contact line power supply, wiring along the track, equipped with current collector.

Load marking:White load labels are affixed to the track beams, indicating the rated lifting capacity, and the load is traceable by zone.

Safety devices: Upper and lower limit switches, track end stops and buffers, overload protection, and power failure braking.

Working Principle

Each suspension rail constitutes an independent hoisting unit: the electric chain hoist completes the vertical lifting of the workpiece; the traveling trolley drives the hoist to move longitudinally along the rail; multiple rails are arranged in parallel, each covering a working zone, and the hoists at adjacent workstations do not interfere with each other and can work simultaneously. The operation is completed independently by personnel at each workstation through a hand-held flashlight, without the need for unified scheduling or the assistance of professional crane operators, reducing hoisting waiting time to zero.

Core Advantages

Parallel hoisting at multiple workstations:Multiple rails are connected in parallel and each rail is independent, allowing multiple workstations to lift simultaneously without queuing, which is a direct solution to the "race against time" dilemma.

Zero ground occupation:All loads are borne by the roof truss, with no supporting columns, and machine tool layout, forklift access, and personnel movement are completely unobstructed.

High space utilization:The track is laid in the "unused space" under the roof truss, without sacrificing any ground floor or mid-level headroom.

Modular and scalable:Standard sections can be spliced together, and tracks, number of tracks and workstations can be increased at any time, allowing for production line expansion without interruption.

Easy to push:The low-friction roller design requires little pushing force when fully loaded, and can be easily positioned by a single person. It is less labor-intensive than manual lifting and more flexible than a forklift.

Load zoning is traceable:Each rail is labeled with a load rating, making the rated load clear at a glance, overload risk is controllable, and safety management is standardized.

Safe and reliable:The hoist is equipped with upper and lower limit switches, overload protection, and power failure braking; the end of the track is equipped with a stop and buffer.

Low noise and clean operation:Low operating noise and no exhaust gas, suitable for long-term operation in indoor machine tool workshops.

Application Scenarios

Multi-station loading and unloading of CNC machine tools; hoisting of flange/disc/ring workpieces; parallel material transfer at multiple stations on assembly lines; workpiece transfer between machining processes; mold disassembly, assembly, and flipping; assembly of pump, valve, motor, and reducer components; equipment hoisting in maintenance workshops; light-duty hoisting in cleanrooms in electronics and light industry sectors; production lines where ground logistics channels must be kept unobstructed.
