The problem: an old building and a new crane
The customer's stamping shop was built for older cranes with a lower profile. Replacing them with standard single girder units would have lost hook height, and the presses need the hook to clear tall dies.
Raising the roof was not an option during production. The crane had to fit the building that already existed.
What we specified
Two European single girder cranes, 5 t × 16.5 m, with low-headroom hoists. The compact hoist sits closer to the girder, recovering about 400 mm of hook height compared with a standard Chinese hoist — enough to clear the tallest die set.
VFD control on hoist, trolley and long travel gives stepless movement. In a stamping shop, that matters: the load is a die or a stack of blanks, and a crane that starts with a jerk swings the load into the press.
Because the building already existed, we supplied precise wheel loads before production so the customer's engineers could confirm the existing runway beams and brackets would take the new cranes.
What was delivered
- 2 × 5 t European single girder cranes, 16.5 m span, low-headroom hoists
- VFD control and radio remote
- Spare hoist parts
- English operation manual and installation drawings
- Wheel load data for the existing runway check
Installation by the customer's own team
The customer's local installation contractor erected both cranes using our drawings, with remote support during commissioning. No technician travelled to site.
That worked because the crane was a standard European configuration and the building interface had been settled in advance: rail gauge, buffer positions, hook approach and wheel loads were all confirmed before shipment.
Result
Both cranes fit the existing building, the hook clears the tallest dies, and die changes no longer swing. The customer replaced two cranes without touching the roof or the runway structure.
Contract to shipment: 30 days.
