Deliver Double Girder Overhead Crane to Mexico

Project Background

A new energy manufacturing base in Huzhou, Zhejiang, specializing in energy storage equipment and hydrogen energy devices, required a high-load, highly collaborative lifting equipment cluster for its new assembly workshop. The workshop features a large span and high headroom, requiring multiple cranes to operate simultaneously, placing extreme demands on the stability and compatibility of the lifting system.

Needs Assessment & Solution Design

Harriet, Sales Manager at Yu’an Crane, collaborated with the technical team to define core requirements:

• A cluster consisting of 2 units of 20/5-ton double girder overhead cranes and 4 units of 10-ton single girder overhead cranes
• 30m workshop span and 12m headroom, requiring full coverage and sufficient lifting height
• Multi-crane simultaneous operation with anti-collision and precise positioning functions
• Low-noise, stable operation to meet the precision manufacturing needs of the new energy industry

The technical team provided a tailored solution:

• 20/5-ton double girder cranes feature lightweight main beams and high-precision variable frequency drives for accurate heavy component lifting
• 10-ton single girder cranes are equipped with intelligent limit systems for multi-machine anti-collision
• All units are coated with anti-corrosion material and fitted with dust-proof electrical boxes to meet clean production requirements

Custom Manufacturing & Quality Assurance

Production of the crane cluster began with customized specifications:

• Double girder main beams are fabricated from Q355B high-strength steel, treated with shot blasting and epoxy zinc-rich coating
• Core electrical components are sourced from Schneider for long-term stability under high loads
• Each unit undergoes dynamic and static load testing, with anti-collision systems verified via multi-machine simulation
• Mid-term factory inspections were conducted to verify lifting accuracy and collaborative performance

On-Site Installation & Commissioning

The installation team completed track laying, assembly, and cluster commissioning of 6 cranes in just 15 days:

• Calibrated the travel precision of double girder cranes to ensure positioning errors of less than 5mm across the 30m span
• Conducted multi-machine anti-collision system testing to ensure safe simultaneous operation
• Final tests confirmed the cluster system can lift 20-ton heavy components and 10-ton precision modules simultaneously, fully meeting production needs

Personnel Training & Client Feedback

A 3-day specialized training program was provided, focusing on multi-crane operation protocols and emergency response.

Since delivery, the new energy base has seen a 60% increase in assembly efficiency. The client’s Production Director commented:

“Yu’an’s crane cluster is perfectly suited to our new energy equipment manufacturing. The multi-machine collaboration is highly efficient, and the equipment operates stably and accurately—providing a solid foundation for our capacity expansion.”
