Anti-sway Gantry Crane

Product Introduction

Anti-sway Gantry Crane is an intelligent precision lifting gantry crane equipped with full digital VFD closed-loop anti-sway control system. Compared with ordinary gantry cranes, its core advantage is real-time calculation of load pendulum amplitude to automatically adjust acceleration and deceleration, reducing cargo swing by over 95%. It adopts single/double box girder or truss frame, matched with wire rope hoist or heavy winch trolley, available in rail-mounted and rubber tyred travelling types. Ideal for scenarios requiring high positioning accuracy, fragile finished goods and dense workshop layout, widely used in precast yards, steel processing plants, machinery assembly workshops and port cargo storage yards.

Core Structural Advantages

1. Intelligent VFD Electrical Anti-sway System Built-in PLC anti-sway algorithm automatically calculates lifting cable length, trolley speed and load swing angle. It micro-adjusts motor acceleration and deceleration to suppress pendulum movement, no waiting time for cargo stabilization, lifting efficiency increased by more than 30%. Suitable for long steel, precast beams and irregular large workpieces.
2. High Rigidity Welded Main Girder Frame Q355 high-strength box or truss main girder with overall stress relief treatment, strong anti-deformation capacity. Double girder structure greatly improves overall stability under large-span heavy load operation, further auxiliary suppressing load swing.
3. Dual Operation & Precise Micro-speed Control Support cabin control + wireless remote control. Micro-speed jog function realizes millimeter-level positioning, perfectly fitting mold assembly, finished steel stacking and component installation without collision damage.
4. Complete Multi-layer Safety Protection Equipped with overload limiter, upper/lower lifting limit, travel anti-collision laser scanner, wind speed alarm, emergency stop and phase loss protection. Rainproof IP54 electrical cabinet, adapt to indoor and outdoor working environments.

Long-Term Factory Benefits

1. Eliminate waiting time for swinging cargo, greatly improve daily handling output
2. Reduce collision damage to finished products, cut material loss cost significantly
3. Lower operator operation difficulty, shorten worker training cycle
4. Reduce impact force on crane structure, extend service life of whole machine and spare parts
5. Small swing saves workshop space, improve utilization rate of factory yard

FAQ

Q1: How effective is the anti-sway system?

A1: The digital closed-loop anti-sway system can suppress load swing by more than 95%. Cargo can be positioned stably without long waiting after trolley starts or stops.

Q2: Can anti-sway function be added to existing old gantry cranes?

A2: Yes, we can provide retrofitting anti-sway control cabinet and supporting program for your original gantry crane to upgrade anti-sway performance.

Q3: Can I choose single girder or double girder anti-sway gantry?

A3: Single girder for light tonnage, small span and indoor general use; double girder for heavy load, wide span and high precision outdoor operation with better stability.

Q4: What is the production lead time?

A4: Standard anti-sway gantry takes 15–30 working days; large tonnage customized models take 30–45 working days after receiving deposit.

Q5: What export certificates can you supply?

A5: Complete CE, ISO, third-party load test reports and full set of customs clearance documents are available.
