HLK Heavy Duty Standard Adjustable Welding Rotator by Bolt

1.     The HLK Welding Turning Roller that Grouped as Heavy duty Welding Rotator:

1)      The loading capacity of 160Ton and above, in the standard Large Weld Rolling Bed that can be up to 1000Ton, for special made at present is max. 2000Ton, are all classified as Heavy duty Weld Rolling Bed: (Fig.1) 

2)      This is where the HLK series adjustable by bolt Welding Rotator stands out from the other two types of HGZ series Self Adjustable and HGZ series Adjustable by Leadscrew Weld Rolling Bed: That only the HLK series Bolt Adjust Welding Rotator can fulfil the challenging task of welding on heavy tonnage workpiece.

2.     The Critical Process Control in HLK Heavy duty Welding Turning Roller:

To achieve the task of heavy loading capacity in the Weld Rolling Bed, two components of these heavy duty Large Welding Rotator play critical role in it:

1)      Securing Bolt in HLK Heavy duty Welding Rotator:

a)       It is fasteners during assembling process on a set of standard HLK Welding Turning Roller adjusting with bolt, which subject to great force;

b)      All these mounting bolts are made of high strength steel, making sufficient intensity of the Weld Rolling Bed;

c)       The size of mounting bolts in a set of bolt adjusting Welding Turning Roller varies based on rated loading tonnage of the Welding Rotator: Larger model of the Weld Rolling Bed are secured with bigger size of bolts;

d)      Under normal condition and proper maintenance of the Welding Turning Roller, these mounting bolts have the same length of service life as the Welding Rotator itself;

2)      The Welding Turning Roller in HLK series Heavy duty Weld Rolling Bed:

a)       Same as the “HGZ Heavy duty Standard Self Adjustable Welding Rotator for Tank”, all the Welding Turning Roller of HLK Large Weld Rolling Bed with tonnage higher than 160Ton are equipped with fully metallic roller: (Fig.2) 

b)      To be specific, these Welding Turning Roller are made of alloy nodular cast iron, with good heat resistant performance.

3.     Usage of the HLK series Heavy duty Weld Rolling Bed Adjustable by Bolt:

1)      Anti Drifting Welding Rotator:

a)       As discussed in the previous product sections, Hydraulic Jack up Weld Rolling Bed, and or Anti Drifting Welding Turning Roller, are all originated from the 60~600Ton loading capacity of Welding Rotator Adjusting by Bolt. Loading tonnage in majority of these Anti Drifting Welding Rotator coincide with that of the Heavy duty Welding Rotator;

b)      These Anti Drifting Welding Turning Roller are often used in national level big projects, where the best degree of precision and quality is required. For example, in China, Oil and Gas Transmission Pipeline from West to East;

2)      Offshore Wind Tower Constructed from the HLK Heavy duty Weld Rolling Bed:

As an emerging industry, the build up of wind tower involves utilization of large amounts of Heavy duty Welding Turning Roller adjusting by bolt;

3)      Oil Tank Produced from the HLK Heavy duty Welding Turning Roller:

As a kind of special requirement and process technology container, welding of oil tank involves application of high quality sophisticated Heavy duty Welding Rotator, especially the Anti Drifting Welding Rotator.

4.     Precautions on Use in Application of the Large Heavy duty Welding Rotator:

1)      Some of these Large Weld Rolling Bed are installed at outdoors working environment. Give protection on it against infiltration of rain, wind, etc. is of primary importance;

2)      Workpiece operated on the large Heavy duty Welding Turning Roller is generally big and heavy. Before loading it onto the Welding Rotator, make sure the smooth exterior surface of barrel body, no sharp particles retained;

3)      Take great care on no bumping happened in the process of workpiece loaded onto the HLK Heavy duty Weld Rolling Bed.

5.     Technical Parameters of the HLK Heavy duty Welding Turning Roller:

Below are specifications of the HLK series standard Automatic Heavy duty Welding Rotator Adjustable with bolt (Heavy duty Weld Rolling Bed):
