LHZ Heavy Duty Fixed Base Column Manual Revolve Welding Manipulator

Quantity:

From this segment we go into series of heavy duty welding manipulator. Same as light duty and medium duty, it can be classified as:

Classification:

    1) Stationary weld manipulator and traveling type (Moving or not);

    2) Manual and or motor drive revolve cross slide Column & boom (Revolve way);

    3) SAW welding column and boom or Strip-cladding or MIG/MAG/CO2 (Welding mode);

    4) Column & boom for tank welding or for pipe line/ boiler (Usage)

 

As in introduced in its product family, sizes of 5×5 and above are grouped into heavy duty efficient welding column and boom.

 

With the increasement of size and loading, as the Chinese saying goes: “Quantitative change causes Qualitative change”, of the same structure and working principle, design and produce of these weld column boom should be taken special attentions on:

Design and Production of: 

    1. Column and Boom:

    See below picture:

    Heavy column and boom

    1) As introduced before, these 2 units constitute “trunk” of welding manipulator;

    2) For these heavy duty tank welding machine for industry, its column, boom and bed have its size sufficiently

       enlarged together with its thickness, making the whole skeleton with sufficient strength and rigidity;

    3) Boom and column are press brake parts made from steel plates, then fabricated into shape, and stress 

       relieved by means of annealing, and fine-machined with planning and grinding;

    4) Unique design on cross section of the column and boom for these convenient tank welding machine;

    5) For boom horizontal stroke longer than 6m, there is a small extending arm fit at the front end of the boom, to

        meet the demand on traveling stroke, together with lessening down total weight of the boom;

    6) The entire piece of boom and column has relative light weight, high stiffness and good stability, serving as a

        reliable body for these big heavy duty welding manipulator.

   2.  Guideway of boom travel

    1) For heavy duty welding manipulator, guideway for both horizontal and vertical movement of boom is heavy

       duty precise rectangular guiderail. See below picture:

     Rectangular Guiderail

    2) These rectangular guiderails are made of high quality steel, and machined with planning machine, of highly 

       degree of precision and strength, guaranteeing quality of this heavy duty accurate column and boom
