T Frame LHT Series Gantry Type I Beam Welding Machine

Overall Structure Characteristic: As you can find from attached photos, Wuxi JACK LHT series H Beam Submerged Arc Welding Machine has its main frame in the form of T shape, hence the product name gets from.

1. Application Feature of LHT Series Gantry type H Beam Welding Machine:

1) Where Used:  The LHT series T frame model is the counterpart of LHC H Beam SAW Machine, in producing large size welding H Beam in semi automatic line, and also can be worked as an individual equipment: 

Design sketch on LHT model machine: (Fig.1) 

2)  Also, customer can use LHA5C and LHZ55Z model machine for welding large size H Beam. But, as introduced earlier, for same size of H Beam produced, LHA series machine has wider machine frame compared with LHT series model.

2. Introduction on T frame of LHT Series Gantry type H Beam Submerged Arc Welding Machine:

Mechanical frame is core and foundation for making sure normal operation of H Beam Welding Machine. It plays the same role as gantry frame in the LHA (LHAZ and LHAC) series machine, the T frame machine body has functions of:  

Mechanical frame of LHT macchine: (Fig.2)

1) Bear Weight of Main Components of H Beam SAW Machine

a) This includes: Electric control board, two sets of SAW welding flux recovery unit (around 70 ~ 80 kgs each set at average, depending how much welding flux loaded);

b) Two sets of welding unit, covering motor drive moving carriage, welding torch, SAW welding wire feeder, welding arc tracing unit;

c)  Transmission unit and accessories;

d)  Altogether, only the two sets of welding power source are put on the floor. The remaining units of the machine are all fit onto the machine T frame;

2) Drive the welding torches in adjusting welding speed, to finish SAW process of the H Beam SAW Machine;

Requirement: For these purposes, the T frame should be strong and sturdy, with sufficient strength and firmness, (likewise, gantry frame for the gantry style LHA series I Beam Gantry Welding Machine, and column beam trolley frame for the column style LHC model machine), in the rough working environment of SAW welding: Lots of heat and fume as well as dust generated at working site.

3. How to Attain Required Rigidity and Strength in T Frame of LHT series Gantry type H Beam Welding Machine:

For this purpose,

1) Advanced Process Technology of Wuxi JACK Machine: Rigidity and strength of the machine T frame are all calculated and simulated carefully in the early stage of design, advanced and reasonable. Main members of the main T Frame are distressed after welding, featuring in safe and reliable running with long term service life;

2) Double Drive for Welding: Same as column type LHC series H Beam Welding Machine, movement of T frame in LHT model machine is double drive (LHA models also). - - Both sides of the T frame are driven with two sets of A.C. motor and reducer, with speed controlled with A.C. inverter (This is also true with the LHA models machine);

3) Safety Measure: At the lateral side of rails, there are stop wheel units, ensuring on smooth and safe running of T frame (This is also true with LHA models H Beam Welding Machine) in the LHT model;

4) Electric control board of the LHT model machine is put at bottom of the T frame on its chassis. This kind of arrangement not only has merit of short and easy cable routing, but also can be served as counter weight for guaranteeing on steady T frame movement.
