The K span roll forming machine is a on-site roll forming machine for the manufacturing of metal span roof for arch building. The k span roll forming machine is a mini factory on wheels that can produce durable steel arch building in days rather than weeks or months. The k span roll forming machine contain of a panel roll forming machine, a panel curving device, engine power unit, control system and trailer to transit to everywhere.
The k span roll forming machine is starts from the unwinding of metal coils,entry the k span panel roll forming machine after leveling , then roll formed to panels , cut to length by hydraulic cutting device, then curve the panels to certain radius,all the power can be supported by the engine power unit mounted on the k span roll forming machine.
Decoiling—guiding& leveling —roll forming—-hydraulic cutting—-storage area—curving—run out table
The whole solution on the k span roll forming machine is combined of uncoiler , stationary hydraulic shear device, main k span roll former,panel storage rack,panel curving device, engine power unit,control system and a trailer.
