I. Project Background and Needs Analysis
Kaida Tiandi Industrial Park in Yunxi is a modern industrial production base where equipment maintenance and inspection are critical. To improve inspection efficiency and safety, the park decided to introduce mobile lift solutions with the following requirements:
- Quantity: 6 mobile lifts
- Personnel: 6 dedicated inspectors, each assigned a unit
- Technical Specifications:
- Max lifting height: 6 meters
- Load capacity: 250 kg
- Single-operator: One worker can independently control lifting and movement
- Maneuverability: Flexible steering for tight spaces
- Durability: Easy maintenance, reliable, and long-lasting
II. Solution Design and Equipment Selection
1. Recommended Technical Specifications
Based on the park’s needs, we proposed an electric-hydraulic mobile lift with the following configuration:
- Model: Self-propelled scissor lift (Final selection: Chison-Lift AT3-4.5)
- Platform height: 4.5 meters (excluding operator height)
- Platform size: 1.8m × 0.65m (sufficient for single-person operation)
- Load capacity: 300 kg (20% above requirement for safety margin)
- Power system: 24V DC motor with maintenance-free battery
- Mobility: Self-propelled, zero-turn radius design
- Control: Integrated platform control panel
- Safety features:
- Fall protection
- Tilt alarm system
- Emergency descent function
- Anti-collision buffer design
2. Flexible Application Scenarios
Advantages for plant maintenance:
- High-altitude work: Easily reaches roof equipment, security systems, HVAC, lighting, pipelines, and cable trays
- Equipment maintenance: Precise positioning for various inspection points
- Tight spaces: Compact design navigates passages ≥1 meter wide
- Multi-point inspection: Single operator moves quickly between zones, improving efficiency by over 30%
III. Predefined Procurement Strategy and Implementation Plan
1. Phased Procurement Plan
| Phase | Task | Timeline |
|---|---|---|
| Market research | Gather data from 3-5 suppliers | Weeks 1-2 |
| Prototype testing | On-site trials of 2-3 models | Weeks 3-4 |
| Bidding & purchase | Issue technical bids, negotiate prices | Weeks 5-6 |
| Delivery & training | Equipment acceptance + training | Weeks 7-8 |
2. Supplier Selection Criteria
- Certification: Special equipment production license required
- After-sales service: Local service network with 4-hour response time
- Spare parts: Guaranteed availability of common components
- Experience: At least 3 successful cases in similar industrial parks
3. Cost Optimization
- Bulk purchase: Discount for buying 6 units (achieved 5% discount)
- Extended warranty: Negotiated free extension to 18 months (originally 12)
IV. Operation and Maintenance Management System
1. Equipment Allocation Plan
| Unit ID | Responsible Area | Primary Use Case |
|---|---|---|
| JD-01 | Zone A Plant | Production line maintenance |
| JD-02 | Zone B Plant | Electrical system inspection |
| … | … | … |
2. Routine Maintenance Protocol
- Daily checks: Hydraulic oil level, battery charge, structural integrity
- Weekly checks: Fastener status, safety device tests
- Monthly checks: Full inspection by technicians
- Annual overhaul: Factory servicing or on-site professional maintenance
3. Safety Regulations
- Certified operators only (requires high-altitude work license)
- Digital usage logs
- Dedicated parking/charging area
- Weather-related usage policies
V. Benefits Analysis
- Efficiency gains: High-altitude prep time reduced from 30 to 5 minutes
- Safety improvement: Eliminated ladder fall risks, reducing accidents by 80%
- Cost savings: 40% lower than fixed lifts in installation/space costs
- Scalability: Equipment can be reassigned as production layouts change
Final Decision: The client selected Chison-Lift AT3-4.5 mobile lifts. This solution established an efficient, safe, and flexible inspection system, ensuring stable equipment operation at Kaida Tiandi Industrial Park.
