European Crane Basics & Selection

Q1: What is a European crane? How is it different?

A: A European crane is a lightweight, compact overhead lifting device designed to EN European standards. Key advantages: compact structure, low deadweight, low energy consumption, smooth operation, quiet and dust-free. Compared to traditional cranes, it offers greater usable space, smaller hook approach, and lower failure rates.

Q2: What European crane models do you offer?

A: Main models: European single girder, double girder, gantry, and suspension cranes, paired with European electric hoists. These cover indoor workshops, outdoor yards, low-clearance buildings, and precision machining facilities.

Q3: What industries use European cranes?

A: Machinery manufacturing, precision machining, hardware, new energy, food & pharma, warehousing, automotive, steel structures, and clean-room facilities — especially where low noise, high precision, and space efficiency are needed.

Q4: Can a European crane fit in a low-clearance workshop?

A: Yes. Low-headroom design saves 300-500mm of lifting height compared to traditional cranes. Minimal hook approach dimensions — no structural modification needed.

Q5: How to choose the right crane capacity?

A: Select based on your heaviest regular lift plus 10-20% safety margin. 1-20t single girder for light duty; 5-50t double girder for heavy duty. We provide free selection proposals.

Q6: Single vs double girder — which one?

A: Single girder for 1-20t, standard spans, normal duty. Double girder for 20t+, large spans, high-frequency or precision lifting — stronger, smoother, longer life.

Q7: Gantry cranes indoor or outdoor?

A: Both. Outdoor models have rainproof, dustproof, anti-corrosion protection. Indoor models focus on lightweight, quiet, precision handling.

Q8: What duty ratings (A3-A7) mean?

A: A3 for low-frequency intermittent use. A5 for industrial 24-hour duty. A6-A7 customizable for heavy-duty high-frequency applications.

Q9: Can old factories be retrofitted?

A: Yes. European cranes are much lighter — no building reinforcement needed, only rail adaptation.

Q10: Suitable for clean rooms?

A: Yes. Enclosed structure, zero dust, no oil leakage, low noise — meets pharmaceutical, electronics, and precision instrument standards.

Q11: Suspension vs bridge crane?

A: Suspension mounts to roof beams, no columns needed, compact and flexible. Bridge crane runs on rails, higher capacity, for heavy duty.

Q12: Good for frequent light-load handling?

A: Very. Smooth start/stop, high inching precision, no swing or impact — ideal for high-frequency light-load production lines.

Q13: Custom non-standard cranes?

A: Yes. Full customization: capacity, lift height, speed, special protection, intelligent controls — all based on your workshop conditions.

Q14: Suitable for coastal humid environments?

A: Yes. Custom anti-corrosion models with shot-blast rust removal, heavy-duty painting, and sealed moisture-proof components.

Q15: Can it operate in extreme cold?

A: Yes. Low-temperature models with cold-resistant motors and lubricants — stable at -30°C.

Parameters & Performance

Q16: Standard capacity, span, and lift height?

A: Single girder: 1-20t, 7.5-31.5m span, 6-12m lift. Double girder: 5-50t, 10.5-31.5m span, 6-18m lift. All customizable.

Q17: Is speed adjustable?

A: Yes. VFD stepless control for hoisting, cross-travel, and long-travel — smooth precision positioning and fast handling.

Q18: Noise level?

A: Below 60 dB — silent gearboxes, precision wheels, enclosed transmission. Far quieter than traditional cranes.

Q19: How much lighter are European cranes?

A: 20-40% lighter than traditional models at same capacity — reducing building load and construction costs.

Q20: Positioning accuracy?

A: Very high. VFD speed control + precision transmission enables accurate inching positioning for precision molds and workpieces.

Q21: Energy savings?

A: 30%+ energy savings compared to traditional cranes. High-efficiency motors + VFD — auto energy-saving under no-load/light-load.

Q22: What is hook approach dimension?

A: Minimum safe distance from hook to column/wall. European cranes achieve very small hook approach, maximizing edge workspace.

Q23: Continuous duty capability?

A: A5 models support 16+ hours continuous operation with stable performance — for factory production lines.

Q24: Wind resistance for outdoor cranes?

A: Outdoor gantry models have anti-wind devices and wind-speed alarms. Automatic stop at 20m/s wind speed.

Q25: Main beam advantages?

A: Fully automatic welded box beam, no butt welds on web plate. High strength, excellent rigidity — no deformation over lifetime.

Safety Features & Operation

Q26: Standard safety devices?

A: Overload protection, upper/lower limits, travel limits, emergency stop, rope break protection, bumpers, loss-of-voltage and zero-position protection — EN compliant.

Q27: Auto-stop on overload?

A: Yes. Electronic overload system cuts power and alarms when load exceeds rated capacity.

Q28: Anti-sway function?

A: Yes. VFD anti-sway uses intelligent speed control to suppress load swing — smooth handling even for beginners.

Q29: Obstacle avoidance?

A: Optional laser/ultrasonic anti-collision — auto slow/stop when obstacles detected. Ideal for multi-crane workshops.

Q30: Emergency stop?

A: Red emergency stop buttons on pendant and control panel — instantly cuts all power.

Q31: Operator license required?

A: Yes, as formal lifting equipment. We provide training and safety guidance for certification.

Q32: Will load fall on power loss?

A: No. Electromagnetic brake locks automatically on power loss — hook holds load securely.

Q33: Purpose of limit protection?

A: Prevents over-travel upward (head collision) or downward (rope break). Auto power cut at limits.

Q34: Multiple cranes same runway?

A: Yes. Anti-collision and zone control maintain safe distances — for multi-crane parallel operation.

Q35: Remote safety monitoring?

A: Optional intelligent monitoring: real-time data, duty cycles, faults, overload records, remote alerts.

Troubleshooting & Common Issues

Q36: Crane shaking or swinging?

A: Causes: uneven rails, misaligned joints, worn wheels, loose connections, or VFD mismatch. Calibrate rails, repair treads, tighten connections, optimize speed control.

Q37: Abnormal noise?

A: Usually dry gearbox, worn bearings, wheel friction, or loose parts. Check oil, tighten bolts, replace worn parts, lubricate.

Q38: Weak hoisting or load dropping?

A: Check: unstable voltage, brake pads not releasing, gearbox failure, or wire rope jam. Fix voltage, adjust brake, inspect transmission, clear debris.

Q39: Impact or swing on start/stop?

A: VFD ramp times too fast. Professional adjustment of acceleration/deceleration eliminates impact.

Q40: Wire rope with broken strands?

A: Over 3 broken strands in one lay length — replace immediately. Scattered breaks: monitor closely.

Q41: Brake failure or delayed braking?

A: Worn pads, excessive gap, spring fatigue, or control fault. Adjust gap, replace pads, inspect circuits.

Q42: Crane won't start?

A: Check main power, emergency stop, limit switch reset, wire connections, voltage stability.

Q43: Trolley runs off-track?

A: Uneven wheel wear, rail misalignment, or wheelbase issues. Calibrate rails, adjust wheels, replace worn ones.

Q44: Limit switch failed?

A: Stop immediately. Check wiring, switch condition. Replace faulty components before resuming.

Q45: Oil leaking?

A: Aged seals, loose bolts, or excessive oil level. Tighten, replace seals, adjust oil level.

Installation, Maintenance & After-Sales
