टिप्पणी: These technical parameters are applicable to Weihua NR, ND, CD/MD series electric hoists for construction. Different project scenarios can be customized based on load capacity, उठाने की ऊँचाई, space constraints and control systems. If you need to select a model for a specific construction site, we can also provide matching suggestions and CAD drawing support. Please let us know if necessary.
1. Heavy-Duty Performance
Weihua electric hoists are engineered for continuous and intense operation typical on construction sites. With durable lifting mechanisms and high-torque motors, they can effortlessly handle heavy building materials like concrete blocks, steel structures, rebar bundles, and prefabricated panels.
2. Adaptability to Harsh Environments
Construction environments often involve dust, moisture, temperature fluctuations, and rough usage. वेइहुआ विद्युत उत्तोलक feature:
Corrosion-resistant coatings for outdoor use
धूल- and water-proof motor enclosures (आईपी55)
High-tensile wire ropes or alloy chains designed for rugged conditions
Optional explosion-proof versions for high-risk zones
3. Optimized for Space and Height Constraints
Low headroom and compact designs ensure efficient operation in tight spaces, जैसे कि:
Elevator shafts
Scaffolding frameworks
Underground tunnels and foundation pits
This allows contractors to maximize lifting height even in areas with limited vertical clearance.
4. Intelligent Monitoring & Maintenance
Advanced models can be integrated with:
Real-time load monitoring
Black-box-style operation history recording
Predictive maintenance reminders based on operating hours
Remote diagnostics via IoT/5G modules for large-scale construction project management
Weihua construction hoists are trusted in high-rise and infrastructure projects across the globe, including:
1. चीन: Used in over 80% of tier-one city construction sites
2. Brazil: High-rise apartments in São Paulo equipped with NR series hoists
3. UAE: Integrated into metro station building projects in Dubai
4. Kenya: Used in Nairobi’s prefabricated housing construction
5. दक्षिणपूर्व एशिया: Widely applied in bridge erection and highway projects
