Customer Case 1

Industry: Heavy Machinery / Cranes
Customer: Major European Crane Manufacturer
Project Location: France

Background


A leading crane manufacturer required a reliable crane capable of lifting over 100 tons in a challenging industrial environment. The crane needed a drive system that could safely lift and lower heavy loads, operate under continuous duty cycles, and endure extreme conditions without failure.

Challenge

  • High load stress on the crane’s gear system, especially under maximum load.

  • Frequent wear and tear due to continuous heavy-duty operations, leading to shorter lifespan and higher maintenance.

  • Excessive heat generation from high sliding contact between worm and worm wheel, leading to inefficiency and potential failure.

Solution

  • Custom-designed worm gear reducers were selected for their high reduction ratios and self-locking capabilities.

  • Advanced materials, including high-strength steel and hardened surfaces, were used to resist wear and deformation.

  • Enhanced lubrication systems with high-performance synthetic oils reduced friction and heat generation.

  • Cooling channels were integrated into the gearbox housing to effectively dissipate heat and improve operational efficiency.

Results

  • Load capacity increased from 80 tons to 100 tons, leading to enhanced operational efficiency.

  • Operating temperature was reduced from 85°C to 65°C, improving system reliability.

  • Maintenance intervals were extended from every 6 months to once a year, resulting in significant cost savings.

Customer Feedback


“After switching to this new worm gear solution, we’ve seen a remarkable improvement in crane performance. The maintenance intervals are longer, and the reliability has been unmatched in our previous systems. The reduced heat generation has also increased our operational uptime.”

Key Takeaway


Worm gear reducers, when designed with the right materials, lubrication, and thermal management systems, can increase load capacity, reliability, and service life, making them ideal for heavy-duty industrial applications.
