How to Choose a Wire Rope Hoist: 5 Critical Selection Factors
Wire rope hoists are the preferred choice for heavy-duty lifting. [Jiangyin Dingli High Tech Cranes Co.，Ltd.] with 20 years of engineering expertise, provides a scientific selection framework.
1. Determine Load Requirements
Rated capacity: Add 25% safety margin to maximum working load
Duty class: FEM M7 for high-frequency operation (>240 cycles/hour)
Case study: 250t foundry hoist for shipyard with 10-year maintenance-free operation
2. Evaluate Working Environment
Indoor/outdoor: IP65+ rating mandatory for outdoor use
Hazardous areas: Explosion-proof models (ATEX certified) for petrochemical plants
Temperature: Standard range -20℃~60℃, special lubrication for arctic conditions
3. Select Lifting Height & Speed
Lifting height: 6-50m standard, custom solutions available
Travel speed: 5-10m/min for normal operation
Precision: 0.5m/min micro-speed option
Case: Dual-speed system increased productivity by 40% at a container port
4. Safety Features Configuration
Mandatory: Overload protection
Dual braking systems
Recommended: Anti-sway control (±1° accuracy)
Rope breakage monitoring
5. Smart Upgrade Options
Basic: VFD control + limit switches
Advanced: Load monitoring + remote diagnostics
Premium: Digital twin + predictive maintenance
