1) From March 2009 to beginning of September 2026, for close to 2 decades, Wuxi JACK has provided over 300 sets of sturdy and durable H Beam Straightening Machinery to customers, which differ in structures and straightening capacity:
2) Work principle, and operation of Wuxi JACK YTJ60/ YTJ80 heavy duty Hydraulic H Beam Straightening Machine: (Fig.1, 2)
As the most extensive selling volume in product family H Beam Straightening Machinery, Wuxi JACK H Beam Flange Straightening Machine can be classified into 3 major types, differed on:
1) Straightening force: Motor drive on medium duty H Beam (Yield strength and flange thickness), or hydraulic drive on heavy duty;
2) H Beam orientation: Mainstream in vertical, and small percentage in horizontal;
3) Yield strength of H Beam: From medium level 235MPa to heavy duty 345MPa or 485MPa;
To be specifically,
1) HYJ models motor drive: For straightening on H Beam of 235MPa yield strength, flange thickness 6mm- 40mm, in vertical;
2) YTJ models hydraulic drive: For straightening on H Beam of:
a) 345MPa yield strength, flange thickness 6mm- 100mm,
b) Or ASTM A709 WTB1, Grade 50, of 485MPa yield strength, flange thickness 6mm- 80mm,
c) H Beam in vertical;
3) WJ models hydraulic drive: For H Beam of 235MPa yield strength, flange thickness 6mm- 40mm, H Beam in horizontal;
These wide variety of Wuxi JACK H Beam Straightening Machinery provides rich assortment for customer choice, and plays consistent high performance at various steel structure H Beam Production Line:

1) These solid rollers are critical work element on flange straightening;
2) The straightening rollers are made of high strength alloy steel, precisely machined, and went thru strict control integral heat treatment: Tempered and quenched, to guarantee on its superior mechanical performance;
1) There are 2 pairs of web alignment rollers in flange straightening mechanism, being used for flexibly clamping on H Beam web into vertical during operation;
2) These symmetrically assembled web alignment rollers are guided precisely in bushing, on its leftward and rightward movement, to be suitable different flange width of H Beam;
1) As a heavy force machinery, high strength mechanical frame of machine is of vital importance, to guarantee on consistent and high level straightening performance;
2) Assembly on all assemblies/ units/ components: Straightening rollers/ Web alignment rollers/ shaft box/ T slot of work table/ Straightening unit..., are all controlled precisely with strict control tolerance, controlled with IPV (Internal process validation);
1) The default color of machine is JACK blue. Customer can denote on preferred color, based on your preference and company policy;
2) Testing on flange straightening performance is by means of workpiece test, within the max. rated specification of H Beam. But this can only be carried out at customer workshop.
Here we take the largest model YTJ80 hydraulic drive H Beam Straightening Machinery, which has rather good selling performance in the recent 2 years of 2025 and 2026 as example:
