How to identify lifting tackle and I-steel tackle

Lifting pulleys and I-steel tackles will not be confused by the concept of the I-beam block and the lifting block when choosing a friend. Today, I will explain to you in detail about the relationship between the lifting tackle and the I-beam. Many of my friends will use I-steel tackles as lifting tackles. To be sure, this is correct, but can lifting tackles be used as I-beams? The answer is no. The simple point is that the I-beam block must be a lifting block, and the lifting block does not always have an I-beam block, that is, the I-beam block is just one of the lifting blocks. The biggest difference between I-section steel blocks and lifting blocks is that they can be used on I-beams.

Let us first explain what I-beams are. The I-beam in the so-called I-steel block is also referred to as a steel beam, and is a long steel sheet with an I-shaped section. Its specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d). For example, "worker 160*88*6" means that the waist height is 160 mm, the leg width is 88 mm, and the waist thickness is 6 mm I-beam. I-beam specifications can also be used to represent the model, the model shows the height of the waist centimeters, such as workers 16 #. If the waist height of the same I-beam, if there are several different leg width and waist thickness, need to add abc to the right of the model to distinguish, such as 32a#32b#32c# and so on. I-beams are divided into ordinary I-beams and light I-beams, including cable I-barrels. The specifications of hot rolled ordinary I-beams are 10-63#. The standard hot-rolled I-beams supplied by the supplier and buyer are 12-55#. I-beam blocks are widely used in various building structures, bridges, vehicles, supports, machinery, etc.
