Medium ZHJ8018 Model 3 in 1 H Beam Assembly Weld Straighten Integral Machine

A. Outline on ZHJ18 Model 3 in 1 H Beam Welding Machine:

ZHJ8018 is the middle one of standard models ZHJ series 3 in 1 H Beam Assembly Weld Straighten Integral Machine, for fabricating on welded T Beam H Beam of web (wall) height 200~ 1800mm; Other specifications of delivered H Beam are same as those of ZHJ15 model machine.

B. Comparison between PHJ and ZHJ series 3 in 1 H Beam Fabrication Machine:

1. Finished Workpieces from PHJ and ZHJ Integral Function H Beam Welding Machine:

As introduced in the product page of Integral Function H Beam Welding Machine, ZHJ series automatic Vertical H Beam Welder is for producing symmetric cross section welded T Beam H Beam, while PHJ series can fabricate on both symmetric and asymmetric cross section beams. See as below sketch on 2 major types of welded H Beam: (Fig.1)

2. Different H Beam Assembly Style in PHJ and ZHJ Models SAW H Beam Fabrication Machine:

Difference mainly happens at the assembling step:

1) In PHJ series automatic 3 in 1 H Beam Welding Machine, it is semi-automatic: One side of H Beam is with hydraulic drive clamping, while the other side of H Beam is with manual adjustment handwheel;

2) In ZHJ series machine, H Beam assembly is fully automatic, driven with hydraulic oil cylinder, at both sides of its web in phase;

3. Structure and Working Principle of PHJ and ZHJ Series 3 in 1 H Beam Welding Machine:

Difference also lies in assembly unit of the two series of machine. Welding unit and straightening unit are the same. To be specific, Positioning of flange and web at both sides of machine:

1) Drive: Both sides of H Beam web alignment rollers are driven with hydraulic cylinder in phase, connected together by a mechanical shaft which is installed at the bottom of the machine mechanical main body;

2) Transmission of alignment rollers: By means of chain and sprocket;

3) Guiding of alignment rollers: Guiding bush, inside is nut and screw;

4. Manufacturing Cost and Quotation of PHJ and ZHJ Series 3 in 1 H Beam Welding Machine:

In general, price of ZHJ series 3 in 1 Vertical H Beam Welder machine is about 5~ 6% lower than that of PHJ series;

5. Running Cost and Maintenance on PHJ and ZHJ Integral Function H Beam Welding Machine:

In general, PHJ and ZHJ series machines are at the same level, which major covers electricity and welding consumables;

6. Market Prospect on PHJ and ZHJ Integral Function H Beam Welding Machine:

Generally speaking, in China more customers prefer ZHJ series machine; While in overseas market PHJ series machine takes majority share.
