LHZ Heavy Duty Fixed Base Column Manual Revolve Welding Manipulator

1. Technical Specifications and Loading Scope of Heavy duty Welding Manipulator:

These are 2 criterions on distinguishing heavy duty Welding Column and Boom from light duty and medium duty models product:

1) Max. loading capacity at the front end of horizontal boom is 200kg to 400kg;

2) Moving Stroke: Horizontal Boom up and down along Y axis and horizontal X axis moving stroke is 5,000mmｘ5,000mm and more (Models of LHZ5050 and above).

2. Classification on Heavy duty Welding Column and Boom:

Same as Light duty and Medium duty models of Welding Manipulator, Heavy duty products can further be classified into several branches of:

1) Based on with motor drive moving trolley: Stationary structure, versus traveling type machinery;

2) Based on manual and or motor drive column revolve type: In practical application, manual revolve column has wider adoption than motor drive upright column rotation, in configuration of Welding Manipulator;

3) Based on welding mode: SAW (Submerged arc welding), or Strip Cladding Weld Column Boom, or MIG/ MAG/ CO₂. For Heavy duty models manipulator welding machinery, the welding mode of SAW has the largest share;

4) Based on applicating industries, or usage: Industrial tank welding, or for Pipe Line/ Boiler, etc.

3. Technical Specialties of Heavy duty Welding Manipulator:

With the increasement of overall dimensions and boom end loading in Welding Column & Boom, as the Chinese saying goes: “Quantitative change causes Qualitative change”, even with the same structure and working principle as light duty and medium duty models equipment, design and process technology of heavy duty models manipulator welding machine are specifically treated as below:

A.  Welding Column and Boom:

See below picture: 

Making delivery on heavy duty LHZ5050 model at Wuxi JACK facility: (Fig.1)

The above small photo gives novel viewpoint on horizontal boom and vertical column, which constitute “trunk” of the manipulator welding machinery:

1) Strengthened Mechanical Main Frame: As can be seen from the above photo, for this heavy duty Industrial Tank Welding Machine, its upright column/ horizontal boom and base bed have sizes sufficiently enlarged, including length/ width/ height and thickness, making the whole skeleton of the heavy duty Welding Manipulator gaining sufficient strength and rigidity;

2) Process Technology Making Welding Column & Boom: The Column & Boom welding machine are press brake parts made from high intensity steel plates, then fabricated into shape, and stress relieved by means of annealing, and finally precisely machined by means of planning and grinding;

3) Cross Section of Upright Column and Horizontal Boom: Unique design on cross section in heavy duty models of Industrial Tank Welding Machine;

4) Small Arm at Front End of Horizontal Boom: When boom horizontal stroke is equal to or longer than 6000 mm, there is a small extending arm fit at the front end of the horizontal boom. In this way, the Heavy duty Welding Manipulator can not only fulfil on the task on effective moving stroke, but also reducing total weight of the boom;

5) Summary: The entire group of column and Boom welding equipment has relative light weight, high stiffness and good stability, serving as a reliable mechanical body of LHZ series Heavy duty models products.

B. Horizontal Boom Moving Guideway in Heavy duty Welding Manipulator:

1) Guiderail: For heavy duty models equipment, guideway of both horizontal and vertical movement of boom is adopted with heavy duty precise rectangular guiderail. See below picture:  

Heavy duty precise rectangular guiderail of Wuxi JACK Welding Manipulator: (Fig.2)

2) These rectangular guiderails are made of high quality steel, and machined with planning machine, in highly degree of precision and strength, fully guaranteeing on stable quality of the heavy duty manipulator welding machines.
