* Description of the machine

Large-span girderless vault making machine is comprised of decoiler, forming unit, hydraulic mould cutting device, electric control system, hydraulic system and unloading rack. All parts are mounted on a mobile pedestal. So it is suitable for site working.

* Features

- Rollers are made of good steel, coated with rigid chrone.

- There is an auto-feed device which can feed 0. 8-1. 5mm color steel sheets. During production, there is no need to adjust the gaps between rollers.

- Adjustment of curving degree adopts handwheel and counter and thus makes easy operation and ensures quality and accuracy.

 

- Light and convenient hoist, only 2kg (those from USA is 30kg). And thus makes quick and convenient installation.

 

- Large span, high corrugation, high tension strength, nutless, etc.
