QDX 16 Ton FEM Hoist Design Solutions
A. Dual-Speed Precision Control
- Challenge: The client required precise positioning (±2mm accuracy) for EV battery module assembly.
Solution:
- Low-speed mode (0.45 m/min): Enabled micro-adjustments during component alignment.
- High-speed mode (2.7 m/min): Accelerated material transfer between workstations.
- Integrated anti-sway technology minimizes load oscillation during movement.
B. Space Optimization
- Challenge: Limited vertical clearance in the facility.
Solution:
- The low-headroom trolley design saved 15% vertical space compared to traditional hoists.
- The double girder structure provided superior stability without increasing the footprint.
C. Energy Efficiency
- High-class Motor + VFD: Reduced energy consumption by 25% versus hydraulic systems.
- Electromagnetic disc type brake system: Captured kinetic energy during deceleration, making the lifting smooth and stable.
D. Compliance
- Certifications: CE marking (EU) and ISO 9001/45001.
- Local Adaptation: Collaborated with Toronto-based engineers to customize cold-weather components (e.g., frost-resistant wire ropes).
eléctrico de la grúa Safe Operations
Pre-Operation Safety Checks
A. Equipment Inspection
- Wire Rope: Check for fraying, kinks, or broken strands (replace if damage exceeds 10% of rope diameter).
- Hook: Inspect for cracks, deformation, or wear on the latch.
- Brakes: Test emergency and service brakes for responsiveness.
- Limit Switches: Verify upper/lower travel limits and overload protection systems.
- Electrical Components: Look for exposed wires, loose connections, or corrosion.
B. Load Capacity Compliance
- Never exceed the Working Load Limit (WLL) marked on the hoist.
- For tandem lifts (multiple hoists), ensure load distribution is balanced and certified by an engineer.
C. Environmental Readiness
- Temperature: Use hoists rated for ambient conditions (e.g., -20°C to +40°C for standard models).
- Hazardous Areas: In explosive atmospheres (e.g., chemical plants), use ATEX-certified hoists with anti-spark components.
Safe Operation Procedures
A. Lifting and Moving Loads
- Centering the Load: Ensure the load is centered under the hook to prevent swinging.
- Smooth Acceleration/Deceleration: Use variable frequency drives (VFDs) to avoid sudden jerks.
- Anti-Sway Systems: Activate technology (if equipped) to minimize load oscillation.
B. Speed and Control
Dual-Speed Modes:
- Low Speed (0.1–1 m/min): For precise positioning (e.g., aligning machinery).
- High Speed (5–20 m/min): For general material handling.
- Remote Controls: Maintain a safe distance from the load during operation.
C. Prohibited Actions
- Do NOT lift loads over personnel.
- Avoid side-pulling or dragging loads horizontally.
- Never use the hoist to lift people.
Post-Operation Safety
- Parking: Secure the hoist in a designated area, raise the hook to mid-height, and power off.
- Lockout/Tagout (LOTO): Isolate energy sources during maintenance.
- Post-Use Inspection: Document any issues (e.g., unusual noises, brake slippage).

How to Purchase an Electric Hoist from DQCRANES
Step 1: Assess Your Requirements
- Application: Define the hoist’s purpose (e.g., automotive assembly, warehouse logistics, mining).
- Load Capacity: Confirm the maximum weight to be lifted.
- Lifting Height: Specify vertical travel distance.
- Duty Cycle: Determine usage frequency.
- Environmental Conditions: Consider temperature, humidity, and hazardous areas (e.g., explosion-proof areas).
Step 2: Contact DQCRANES
- Website/Email: Visit DQCRANES’ official website – www.hoistdq.com or email sales@hoistdq.com.
- Request a Quote (RFQ): Provide technical specifications and site conditions for a tailored proposal.
Step 3: Review Technical Proposal
DQCRANES will typically provide:
- 3D CAD drawings for hoist and runway system, price list.
