FAQs

Q1: How does KAIBO reduce noise in high-torque crane reducers?
A:KAIBO uses precision-ground 18CrNiMo7-6 gears with optimized profiles to minimize vibration, achieving ≤75dB. The ductile iron housing has noise-dampening ribs and anti-resonance design, while forced lubrication ensures smooth engagement. This dual solution works well in urban and port areas.

 

Q2: What’s the difference between IP65 and IP67 protection ratings for crane reducers?
A:IP65 offers full dust protection and resists low-pressure water jets, suitable for 80% of outdoor use. IP67 adds temporary submersion (1m/30min), ideal for floods or high-pressure washdowns. KAIBO provides both with corrosion coatings and sealed bearings for harsh sites.

 

Q3: What is the delivery time for KAIBO’s custom crane gearboxes?
A:Standard models (10k–100k N·m) ship in 72 hours. Custom solutions (e.g., 500-ton wind reducers) take 4–6 weeks. Our modular design pre-makes core parts, cutting lead times by 30%. All orders include 24/7 support and ISO 9001 checks.
