Double Girder Overhead Crane 10 Ton S21mH7m Multi-Crane Same-Runway

The 4 cranes on the same 170m runway configuration is designed for North American workshops requiring high-throughput multi-crane operations. Reasons for 4 cranes:

• Parallel handling: 4 cranes can work on different sections of the 170m runway, handling 4 simultaneous lifting operations
• Segmented production: Long production lines can have dedicated cranes for each processing zone
• Tandem lifting options: Two or more cranes can work together to lift loads above 10t (with proper tandem control)
• Reduced waiting time: When one crane is busy, others can continue working

The laser anti-collision system works as follows:

• Laser sensors: Each crane is equipped with laser distance sensors that continuously measure the distance to adjacent cranes
• Automatic slow-down: As two cranes approach each other, the system automatically slows them down
• Automatic stop: When the minimum safe distance is reached, the system automatically stops the cranes
• Independent operation: Each crane has its own anti-collision system, ensuring complete coverage
• Override options: Manual override for maintenance and special operations with proper safety protocols

This configuration is essential when multiple cranes share a runway — without proper anti-collision, crane-to-crane collisions can cause serious damage and safety hazards.

SEW motors and gearboxes are specified for all motions (hoist, trolley, long travel) because:

• Premium reliability: SEW is globally recognized for reliability in continuous industrial operations
• Energy efficiency: SEW motors are designed for high efficiency, reducing power consumption
• Global spare parts: SEW has an extensive global service network — spare parts are readily available in North America
• Integrated motor + gearbox: SEW supplies matched motor and gearbox units, ensuring optimal performance and easier maintenance
• CSA compatibility: SEW motors and gearboxes are available in CSA-certified configurations for North American markets
• Consistent quality: All SEW components are manufactured to the same high-quality standards, ensuring consistent crane performance

For a 4-crane, 170m runway, high-throughput operation in a North American workshop, SEW motor and gearbox package is the right choice for reliability and long-term operational efficiency.

CSA certification (Canadian Standards Association) means the crane meets the electrical and safety requirements for the North American market:

• Electrical safety: All electrical components meet CSA C22.2 standards
• North American compliance: CSA is recognized throughout Canada, the United States, and Mexico
• Industrial safety: The crane's safety systems (brakes, limit switches, overload protection) meet CSA industrial requirements
• Inspector acceptance: CSA certification simplifies approval by local electrical and safety inspectors
• Insurance compliance: Many North American industrial insurance policies require CSA-certified equipment
• Operating permits: CSA certification is often required for crane operating permits in North American jurisdictions

For a North American workshop, CSA certification is essential — it ensures the crane can be legally installed, inspected, and operated in compliance with local regulations.

Eight numbers on this multi-crane SEW motor CSA overhead crane drawing must match your workshop, or the cranes will not fit or operate correctly:

If any of these eight differ from your workshop, tell Yuantai before ordering — each change affects price and lead time on the multi-crane SEW motor CSA overhead crane.

P30 rail is specified for this multi-crane SEW motor CSA overhead crane because:

• Wheel load per crane: The 10t capacity and 21m span create significant load moment at the end carriages
• 4 cranes on same runway: The rail and runway beam must support the combined load of multiple cranes when they pass on the same rail section
• Long 170m runway: The extended travel length requires a heavier rail section for durability and alignment
• Heavier double girder structure: Each double girder bridge with crab wire rope hoist is heavier than a single girder crane
• SEW motor and gearbox package: The premium SEW package adds mass to the crane, contributing to wheel load
• Long service life: P30 rail is standard for 10t+ double girder overhead cranes in continuous multi-crane workshop use
• Standard availability: P30 is a common rail section, easy to source and replace along the 170m runway

Do not substitute a lighter rail (P22 or P24) without recalculating the wheel load and dynamic forces. The combination of 10t capacity, 21m span, and 4 cranes on the same 170m runway requires P30 or heavier.

No — this multi-crane SEW motor CSA overhead crane with crab wire rope hoist is configured for indoor workshop use. The cranes run on elevated runway rails supported by the building structure, not on ground rails. The CSA certification applies to indoor electrical installations. Outdoor use would require:

• Different crane type — a gantry crane with ground rails and A-frame legs is more suitable for outdoor use
• Weather protection — outdoor electrical enclosures (IP55+) and anti-corrosion treatment
• Wind load design — anti-wind devices and anchoring for outdoor wind exposure
• Different certification — outdoor equipment may require different CSA or other certifications

For outdoor applications, see the MHO 5t-7m A5 Siemens version with anti-wind and anti-toppling design.

To avoid surprises at installation, these items are outside the multi-crane SEW motor CSA overhead crane supply scope unless you specifically add them:

• Runway rail (P30) and rail fasteners for the 170m runway
• Runway beam and building column reinforcement for 4 cranes
• Building structural support for the combined wheel load
• Site power supply up to the crane isolator for 4 cranes
• Erection crane and site lifting equipment
• Local electrical connection and permits (CSA certification helps simplify this)
• Anti-collision system wiring between cranes (if required)

Because the multi-crane SEW motor CSA overhead cranes run on elevated runway rails with 4 cranes sharing a 170m runway, the building structure and rail alignment are critical. Yuantai can provide runway load drawings and installation guidance as optional items.

Send these twelve items and Yuantai will issue a free custom multi-crane SEW motor CSA overhead crane CAD drawing, 3D model, and proposal within 24 hours:

1. Workshop width and runway rail center-to-center distance (span)
2. Required lifting height (m) — e.g., 7m
3. Required lifting capacity (t) — e.g., 10t per crane
4. Number of cranes required — e.g., 4 units
5. Workshop length / crane travel distance — e.g., 170m
6. CSA certification requirement
7. Power supply (V / Hz / Ph)
8. Lifts per hour or hours per day (duty)
9. Building column and runway beam capacity for 4 cranes
10. Laser anti-collision requirements
11. Longest load length and weight
12. Control preference: pendant, wireless, cabin, or both

The more complete the list, the faster and more accurate the multi-crane SEW motor CSA overhead crane drawing, 3D model, and quote.

This published multi-crane SEW motor CSA overhead crane drawing and 3D rendering are a free technical reference — you may use them to plan your workshop and check fit. A project-specific multi-crane SEW motor CSA overhead crane GA drawing and 3D model are also free for standard configurations. A design fee may apply only for complex multi-crane requirements, non-standard anti-collision systems, or specialized customization engineering.
