Manufacturing & Engineering

# From Calculation to Weld, From Weld to Site.

Our crane systems are produced at the Torbalı facility in a five-stage process. Each stage's output is the next stage's input.

## Engineering at Every Stage, From Design to Production.

1. ### Needs Analysis Load, span, lifting height and operating environment are defined.
2. ### Technical Design Steel structure, hoisting group and control system are engineered.
3. ### Production Girders and structural components manufactured at our Torbalı facility.
4. ### Installation & Commissioning On-site erection, adjustment and commissioning.
5. ### Technical Support Maintenance, spare parts and modernization.
