Double Girder Overhead Crane 10 Ton - S9.11m - H12m

SEW motors with full VFD are specified for this textile plant double girder overhead crane because:

• SEW reliability: SEW motors are globally recognized for reliability in humid, chemical-exposed environments like textile dyeing plants
• Full VFD on all motions: Hoisting (0.7-4.3 m/min), trolley (2-20 m/min), and long travel (2-20 m/min) all use variable frequency drives for smooth, stepless control
• Soft starting: VFD eliminates shock loads on yarn packages and dyeing beams, which are sensitive to sudden movement
• Precise positioning: VFD gives millimeter-level control for loading yarn packages onto dyeing machines
• Energy savings: VFD reduces power consumption compared with fixed-speed motors, especially on long 39m travel cycles
• Global spare parts: SEW motors and VFDs are widely available, simplifying maintenance in textile plants worldwide

For a textile dyeing plant where humidity, chemicals, and precision handling all matter, the SEW + full VFD package is worth the investment.

This double girder overhead crane with crab wire rope hoist is specifically configured for textile and yarn dyeing plants because:

• 12m high lift: Dyeing plants often have tall bays for multi-level yarn package storage and dyeing beam handling
• 39m travel length: Covers the full length of a dyeing production line, from yarn intake to finished package output
• Smooth VFD control: Prevents damage to delicate yarn packages and dyeing beams during lifting and travel
• Crab wire rope hoist: Provides higher hook lift and more precise positioning than a single girder hoist
• Corrosion resistance: The crane can be specified with corrosion-resistant treatment for humid dyeing environments (tell Yuantai your humidity level)
• SEW motor reliability: SEW motors perform reliably in the high-humidity, chemical-exposed atmosphere of dyeing plants

If your plant has additional constraints (extreme humidity, acid vapors, high temperature), tell Yuantai at the enquiry stage — additional protection can be specified.

Yes — the 9.11m span is designed for textile plant bays. The fit works as follows:

• Crane span: 9.11m (9110 ± 2.5 mm) — center-to-center distance of the two runway rails
• Total crane width: 3.5m (3500 mm) — including the girder and end carriage
• Main girder center distance: 2.7m (2700 mm)
• Trolley rail gauge: 1.4m (1400 mm)

The 9.11m span fits textile plant bays where the runway rail center-to-center is approximately 9.11m. Because the double girder overhead crane runs on elevated runway rails (not ground rails), the building structure must support the runway beam and wheel load. Confirm with your structural engineer using the 68.2 kN wheel load figure — higher than the 5.08m version because the 9.11m span creates more load moment at the end carriages.

Seven numbers on this double girder overhead crane with crab wire rope hoist drawing must match your textile plant, or the crane will not fit or operate correctly:

If any of these seven differ from your plant, tell Yuantai before ordering — each change affects price and lead time on the double girder overhead crane with crab wire rope hoist.

P30 rail is specified for this double girder overhead crane with crab wire rope hoist because:

• Wheel load: 68.2 kN — higher than the 5.08m version (60.6 kN) because the 9.11m span creates more load moment at the end carriages
• 39m travel length — long runway travel requires a heavier rail section for durability
• Full VFD control — smooth acceleration and deceleration reduce dynamic loads, but P30 is still required for the 68.2 kN wheel load
• Long service life — P30 rail is standard for 10t+ double girder overhead cranes in continuous textile plant use
• Standard availability — P30 is a common rail section, easy to source and replace

Do not substitute a lighter rail (P22 or P24) without recalculating the wheel load and dynamic forces. The 68.2 kN wheel load and 39m travel length both require P30 or heavier.

Yes — this double girder overhead crane with crab wire rope hoist is configured for indoor textile plant use, including the humid environment of dyeing facilities. The SEW motor package is particularly suited to this environment because:

• SEW motor sealing: SEW motors are available with enhanced IP ratings for humid environments
• VFD enclosure: The VFD panels can be specified with IP55 or higher enclosures for chemical-exposed areas
• Corrosion-resistant treatment: Steel structure and fasteners can be treated for corrosion resistance (tell Yuantai your humidity and chemical exposure levels)
• Sealed electrical components: All electrical connections are sealed against moisture and chemical vapors

For extreme conditions (acid vapors, high temperature, or washdown areas), additional protection must be specified — tell Yuantai at the enquiry stage.

To avoid surprises at installation, these items are outside the double girder overhead crane with crab wire rope hoist supply scope unless you specifically add them:

• Runway rail (P30) and rail fasteners for the 39m runway
• Runway beam and building column reinforcement
• Building structural support for the 68.2 kN wheel load
• Site power supply up to the crane isolator
• Erection crane and site lifting equipment
• Local electrical connection and permits
• Corrosion-resistant treatment for humidity/chemicals (if required)

Because the crab wire rope hoist overhead crane runs on elevated runway rails over a 39m length, the building structure is critical — the runway beam and columns must support the 68.2 kN wheel load and the dynamic forces from 2-20 m/min travel. Yuantai can provide runway load drawings as an optional item.
