2)      Each piece of Rotary Welding Table is installed into upright column respectively;

3)       So, during elevation of the 2 pieces of Welding Turning Table, it should be maintained into perfect synchronization;

4)       Workpiece fixation onto Welding Turning Table in Double Column Head and Tail Welding Positioner: (Fig.2)

C.       Safety Assurance of Wuxi JACK Elevating Rotary Welding Table 10 Ton Loading Capacity Double Column Welding Positioning Equipment:

1)       Safety is always the foremost factor to be considered during developing all of Wuxi JACK products, including Double Column Welding Positioner;

2)       Series of measures are taken during the designing process:

1.      Braking Type Motor Reducers are adopted in elevation driving mechanism of Rotary Welding Table;

2.       Slew Ring in Rotary Welding Table of the Elevating Double Column Welding Positioning Equipment:

1)       Great Importance: Slew ring matters most in operation of the Head and Tail Double Column Welding Positioner: It directly determines smooth revolve of Welding Turning Table, as well as sure fire fixation of Rotary Welding Table and working parts;

2)       Safety Holes: In slew rings of Rotary Welding Table in this lifting and rotating Welding Positioning Equipment, there are row of safety holes drilled into the complete external periphery circle of slew rings;

3)       Role of Slew Support in the Head and Tail Welding Positioner:

a)       During welding and idle running of the Head and Tail Welding Positioning Equipment, in case of contingency happens,

b)       Safety pins on assembling mechanism of the Welding Turning Table will be ejected out with no time delay,

c)       And being plugged into safety hole, preventing the Welding Turning Table and workpiece from falling down:

d)       Slew rings and its safety holes to be fit into Welding Turning Table of Double Column Head and Tail Welding Positioner: (Fig.3)

4)       Slew support to be installed in Rotary Welding Table of Head and Tail Double Column Welding Positioner: (Fig.4)

5)       Related Equipment: In this respect, we can see that safety assurance mechanism in Welding Turning Table elevating style Head and Tail Welding Positioner, is similar to another widely applied Welding Positioning Equipment: Welding Column and Boom;

3.       Emergency STOP buttons are installed at numerous places in the whole working zone of Double Column Head and Tail Welding Positioner, for the purpose of easy reach by operators within arms length.

D.     Technical Performance of Double Column Head and Tail Welding Positioning Equipment:

1.      Structure of Head and Tail Double Column Welding Positioner:

1)      Main Units: One set of this elevating Head and Tail Welding Positioner is composed of two sets of upright columns, 2 pieces of Welding Turning Table, and electric system;

2)       So, it is also called Double Column Welding Positioner;

3)      Upright Column Fixation Way: The 2 sets of upright columns can be either fixed into workshop floor, which is used for conditions of fabricating on fixed max. length workpiece in the Double Column Welding Positioner;

4)       Column Moving Type: Or, one set or both sets of the columns can move along ground rails, so that wide variety of workpiece length can be fit into the Double Column Welding Positioner:

5)      Installation and commissioning site of column moving Head and Tail Welding Positioner: (Fig.5)

2.      Simultaneously Elevation Management in the Double Column Head and Tail Welding Positioner:

1)       Drive: Both ends elevation of workpiece chassis along the 2 sets of upright columns are driven with servo motor;

2)       Control: Of which, controlled with input pulse command, elevation of its Welding Turning Table can guarantee fully simultaneous elevation of workpiece at both ends;

3)       This can make sure perfect horizontal level of the workpiece all the while, together with the 2 sets of Rotary Welding Table；

3.       Elevation Safety Management in the Double Column Welding Positioning Equipment:

1)       Braking Type: The 2 sets of Welding Turning Table elevating purpose servo drive motors are all equipped with brakers;

2)       Besides, primary brakers are worm gear reducer, with good braking function;

3)      In this way, elevation safety of workpiece can be fully guaranteed；

4.      Welding Turning Table Elevation Mechanism in the Head and Tail Welding Positioning Equipment:

1)       Transmission: Rotary Welding Table elevation is realized by means of chain and sprocket transmission;

2)       Guidance Unit: There are heavy duty precise guiderails assembled onto the 2 pieces of upright columns, in the Head and Tail Welding Positioner;

3)       Rolling wheels roll along the heavy duty precise linear guiderails, which are assembled onto the upright columns instead of welded structure, guaranteeing stable and reliable elevation of workpiece and Welding Turning Table in the Double Column Welding Positioner:

4)       Driving, Guiding and Transmission unit for Rotary Welding Table elevation in Double Column Head and Tail Welding Positioner: (Fig.6)

5.       Workpiece Revolve in the Welding Turning Table 10 Ton Loading Capacity Double Column Head and Tail Welding Positioner:

1)       Revolve of Welding Turning Table is driven with Y series A.C. motor and reducer, and also equipped with braking unit;

2)      In this way, when the welding turning table and workpieces chassis is revolved to target angular position, it will be locked automatically.
