1.Can cold-rolled coils be transported directly using ordinary forks?
Absolutely not; specialized attachments must be used.
Cold-rolled coils are cylindrical, with a high center of gravity and are prone to rolling. Ordinary flat forks cannot stably support them, making slippage or overturning highly likely. According to safety regulations, specialized attachments that have undergone load testing and certification must be used.
2.Should steel coils be placed vertically or horizontally when transporting them with forks? How should the center of gravity be controlled?
The cylindrical structure of steel coils gives them a "zero stability angle" characteristic, meaning even slight disturbances can cause them to roll. The core principles of safe operation are:
Vertical transport: The steel coil's axis must be perpendicular to the ground, with a low and stable center of gravity. Horizontal placement during forklift transport is strictly prohibited.
Keep a low position: The bottom of the coil should be 400-500mm above the ground. Prolonged travel with the coil raised is strictly prohibited.
Mast tilt: After the steel coil has been lifted approximately 10cm away from the vehicle, the mast should be tilted slightly backward to prevent it from tipping forward and slipping.
3.What are the speed and turning restrictions during forklift transport?
Speed control is crucial for preventing accidents when transporting steel coils with forks:
**Traffic Speed Limits:** In-plant transport speeds must not exceed 8-10 km/h; speeds must be further reduced for operations under cargo hold or in narrow passageways.
**Turning Speed Limits:** Turning speeds must not exceed 5 km/h, and the turning radius should be at least 30% larger than normal. A warning horn must be sounded in advance.
**Physical laws dictate the inherent danger:** When turning a 20-ton steel coil at 10 km/h, the resulting lateral force is sufficient to overturn a 12-ton counterbalance forklift. Therefore, installing a gyroscope-based speed limiter can reduce rollover accidents by 76%.
4.Do I need to check the packaging condition of the steel coils before forklift transport?
It is imperative to check, as packaging defects are a significant cause of accidents.
According to accident statistics, 40% of steel coil handling accidents originate from packaging defects. Before forklift transport, the following must be confirmed:
Steel strapping is intact: The strapping should be free of rust and breakage, and the tension should meet the standard (recommended ≥500 kgf).
Edge protection is adequate: At least four corner protectors per coil should be provided to prevent injury from sharp steel edges.
5.What are the emergency and protective measures for forklift operations?
Establish a comprehensive "prevention-monitoring-emergency" system.
Based on fault tree analysis, the main risks in steel coil handling are concentrated in attachment failure (32%), path obstruction (28%), human error (25%), and packaging defects (15%). The following protective measures are recommended:
Path Clearance: Remove obstacles within a 5-meter radius before operation. The ground slope should not exceed 5°. Operation is strictly prohibited when there is oil contamination.
Visual Awareness: Large steel coils can obstruct the driver's view; a 360° surround view system is recommended.
Emergency Preparedness: Hydraulic rescue supports should be installed within a 15-meter operating radius. Operators must master the "triangular support method" for stabilizing the tipping of steel coils.
Near-Distance Accident Reporting: Any abnormalities (such as attachment cracks or packaging damage) must be reported in writing within 2 hours. Effective early warnings will be rewarded.
