HLK Light Duty Standard Adjustable Welding Rotator by Bolt

Quantity:

Standard models of light duty turning roll adjusted with bolt include 2Ton, 5Ton, 10Ton and 20Ton.

 

We have discussed light duty turning roller of adjusted with leadscrew. So, what is the difference between the two? Or, what is the purpose of producing light duty roller bed adjustable with bolt, if there already exists small turning roll of leadscrew adjusting?


Comparison on light duty turning roll of leadscrew adjustment versus bolt adjustment:

   1) Leadscrew adjustment:

      - Advantage of this type of small turning roller is its stepless changing of roller center distance. So, workpiece

        of any size falling within its range can be welded on the equipment;

      - Disadvantage is its relative higher equipment purchase cost and maintaining cost;

    2) Bolt adjustment:

      - Advantage of this type of small turn roller is its relative lower purchasing cost and maintaining cost;

      - Disadvantage is it can only weld several grades of workpiece size within the rated specification (Usually 4~5

        grades);

As conclusion,

    1) Working site with numerous sizes of workpiece should go for leadscrew adjustment of light duty roller bed;

    2) Working site with only several options of workpiece diameter, bolt adjustment small welding rotator is better

       choice.


Three complements on this kind of equipment:

    1) Due to its small size, these portable welding rotators are sometimes put on the worktable or station, from the

        perspective of ergonomics;

    2) It can be made into traveling roller bed;

    3) Despite its small tonnage, these small portable turn rollers are sometimes adopted with full steel rollers. 

       Check below picture, it is a roller for a 2Ton light duty turning roll. Compared with rubber roller, the full steel

       roller has merit of long service life, no need to be replaced every 2~3years.
