Rust Prevention for the Steel Structure
Promptly touch up anti-rust paint where the coating on mast sections or the hoist cage has peeled off. Regularly apply grease to pins and connecting bolts to prevent rust and seizing caused by rain exposure. When the equipment is parked, elevate the base to avoid prolonged immersion in standing water.
Waterproofing and Moisture Protection for Electrical Systems
Install rain covers on electrical control boxes and variable frequency drives (VFDs), and promptly replace worn-out sealing strips to prevent rainwater ingress. Do not power on the equipment immediately after rain; instead, open the cabinet doors to ventilate and dry the interior, preventing components from burning out due to moisture. Tightly seal any cables with damaged outer insulation using waterproof tape.
Maintenance of Drive Systems and Wire Ropes
Rainwater mixed with silt accelerates wire rope corrosion and strand breakage; apply specialized wire rope grease weekly to seal out moisture. Regularly inspect the gearbox to prevent rainwater entry, which could cause oil emulsification and gear damage. Regularly lubricate guide wheel and roller bearings with grease to prevent seizing caused by silt ingress.
Post-Rain Safety Inspections
After heavy rain, inspect the anti-fall safety device, door locks, upper/lower limit switches, and braking system. Conduct a no-load test run to ensure there is no electrical leakage or binding before resuming personnel or material transport operations.
Protection During Long-Term Shutdowns
When work is suspended, cover the entire unit with a waterproof tarpaulin, disconnect the main power supply, and park the cage in a suspended position to avoid prolonged structural stress. Apply anti-rust treatment to all exposed metal parts.
Conclusion
By adhering to daily waterproofing, moisture-proofing, and rust-prevention maintenance, the SC200 construction hoist can operate stably over the long term at tropical, rainy construction sites, significantly reducing overseas maintenance costs. We offer export-model hoists with enhanced anti-corrosion specifications, tailored for construction in high-temperature, high-humidity regions.
