Jumbo Roll cranes
- Every ton of produced paper is lifted by a crane, and empty spools are returned back to the winding station.
- Dry end, coater and winder cranes are dimensioned for handling all process machine output with a good time margin to avoid any waiting time or slowdowns of production.
- Exact and accurate movements are needed when moving heavy rolls around high speed machines.
- Warm and corrosive environments set high requirements for the protection of all electrics.
- Intelligent load handling technology, sway controls, protected areas and automated handling provide savings in operational costs, flexibility and a remarkable rise in the level of safety.
Dry End Cranes Functions
The dry end crane lifts the full parent rolls from the paper machine winding station either onto a storage rack, a transfer car or into the unwinding position of the calendar, coater or cutting machine. The empty spool shafts are correspondingly returned back onto the paper machine winder‘s storage rails. Typically, during a normal process run there are 1-2 roll changes per hour + the same amount of empty spool returning work cycles. Jumbo roll cranes have multiple purposes, ranging from paper machine maintenance to working as a part of the process machinery.
Intelligent load handling technologies:
- sway control
- target positioning
- protected areas
- semi-automatic jumbo roll handling (pick-up and deposit positions selected by the operator)
- automatic jumbo roll handling (commanded by upper level process control)
- safety hooks with mechanical locking of the load
- remote monitoring of the functions for maintenance
Product range:
- jumbo roll weights from 5-ton tissue rolls to 200-ton coated fine paper or packaging materials
- crane spans according to all paper machine widths from 4 to 12 meters
