Double Girder Overhead Cranes for Clean Rooms

Product Description

Cleanroom double girder overhead cranes are specialized lifting equipment upgraded with comprehensive technology and materials based on standard double girder overhead cranes, specifically designed for the unique requirements of cleanroom environments. The double girder structure provides higher rigidity and torsional resistance. Combined with stainless steel or cleanroom grade surface treatment, enclosed transmission, and sealed electrical systems, the equipment minimizes particle release and vibration while maintaining lifting capacity, meeting ISO/GMP and other cleanroom certification and acceptance requirements.

Design Features of Cleanroom Overhead Cranes

• The rigid double-girder structure improves span load-bearing capacity and torsional stiffness, suitable for handling large and high-precision items.

• Gears, bearings, and lubrication systems employ sealed or oil-free solutions to prevent lubricant dripping and particle generation.

• Servo/frequency conversion drive ensures stable operation and millimeter-level positioning accuracy.

• Compatible with various lifting devices: supports fiber rope/belt hoists and cleanroom chain hoists.

• Equipped with overload protection, dual limit switches, and anti-collision systems to ensure safe operation.
