The crane is a crucial lifting and transportation machine widely used in factories, construction sites, and docks to transport heavy loads, significantly reducing labor requirements and playing a vital role in industrial development. However, most cranes still rely on manual operation.
Because the crane system is underactuated, multi-input multi-output, uncertain, and strongly coupled nonlinear, the crane’s movement during load transportation often causes unavoidable swinging. This limits efficiency improvements and poses safety risks to ground personnel.
Implementing automatic swing suppression greatly enhances work efficiency, ensures production safety, and reduces labor requirements. For practical engineering applications, complex control algorithms are replaced by input shaping technology, which is simple, convenient, and effective for crane system swing suppression.
Product Details
Specifications and Parameters
• Swing amplitude in stop state: less than ±0.5°
• Swing amplitude during travel: ±1°
• Anti-swing adjustment time: 1 swing cycle
• Horizontal rope swing angle approaches zero degrees
Product Features and Advantages
• Crane operation principle: Considering actual operating conditions, the crane maintains a constant rope length via hoist motor braking during horizontal movement with lifted loads. Once positioning is complete and swing has diminished, the hoist motor releases braking to place the load at the designated position.
• During vertical movement, the hoist motor ensures precise positioning, accurately raising or lowering loads to the specified positions.
• During horizontal movement, the motor achieves accurate positioning, with the rope swing angle decaying to zero within a short duration.
