Difference between electric hoist with trolley in the use of I-beam and H-beam

I-beam and H-beam are not the same, the main difference is that I-beam with curved, while H-beam is a standard right angle. When the two types of steel are used as electric hoist running track, choose to pay attention to the difference.

Because the electric chain hoist with trolley is matched with the I-beam, through the above picture we can also learn, the lower edge of the wing plate is not flat but has a slope, so the running wheel to put this on the upper side of the wheel is also a certain angle. If we actually use the H-beam, and then choose to move the electric hoist should be explained to the manufacturer, because the default is to match the I-beam, H-beam need to level the trolley.

Other differences

Process:

I-beam: generally produced by hot rolling process, there are some welding process. The production process of hot rolled I-beam is relatively simple and low cost.

H-beam: mainly produced by hot rolling process, but also part of the welding process. The production process of hot-rolled H-beam is relatively complex, requiring specialized mill equipment, such as rolling in the need to add a set of vertical rolls at the same time for roll rolling, the cost is relatively high.

H-beam waist plate is thicker, wider upper and lower flanges;

I-beam mechanical properties are worse, because only the spindle direction of force, the cross-section coefficient is small will be easy to deformation or distortion;

The performance of the two types of track will also lead to different areas of use, in addition to the use of electric hoist track, H-beam in industrial civil construction, highways and other uses, and I-beam in the field of bridges, steel structures, vehicles, brackets and other areas with more.

Mechanical properties

Bending resistance: H-beam groove depth, thickness, can withstand two directions of force, applicable to withstand bi-directional bending, bending resistance is significantly better than the I-beam, about 5% -10% higher. I-beam side length is small, the height is large, can only withstand a single direction of force, more suitable to withstand one-way bending.

Stability: H-beams have better overall stability due to their more symmetrical cross-sectional shape and are less prone to destabilization when subjected to pressure, tension or bending forces. I-beam in some cases, may be due to the asymmetry of its cross-section shape and lead to a slightly poorer stability, especially in the role of lateral forces, more likely to occur bending deformation.

Torsional properties: H-beams with wide flanges have better torsional properties compared to I-beams. The I-beam has narrower flanges, and its torsional resistance is relatively poor.
