    Main Base

    The main base of the guardrail machine is MS fabricated structure and adequately ribbed to minimize the distortion. It is accurately machined on top and bottom surfaces the threaded holes are made on the bed for positioning the stands.

    Guardrail Machine Stands

    The stands of the crash barrier cold roll forming machine are mounted on the bed of the machine the line alignment can be easily done due to guide ways arranged on the bed of the machine. Each forming station consists of a fixed housing and sliding type out board housing. The mill stands will be arranged to locate shafts mounted on taper bearings. For the top shafts the bearings are housed in the cartridge type bearing blocks. The bottom shaft bearings are located in the bored machined in the housings. The bottom arbors are fixed in position whereas the top arbors along with cartridge blocks could be raised or lowered in vertical guides machined in housings.

    Roll shafts

    The roll shafts dia. 90 mm will be manufactured from quality steel and will be keyed to locate tooling.


    The drive to the roll former will be by means of a gear box system. The main drive will be provided by means of 22.5KW motor


    All the Roller will adopt quality GCR15 steel, heat treatment.

    Hydraulic Cutoff Device

    The guardrail cold roll forming machine adopt post hydraulic cutting device after roll forming. Total power is supply from a 15 KW hydraulic station.
