Heavy-duty racks are prepared and designed according to user qualities and needs, and it is vital to determine the columns in the early stage. I think that everyone understands the importance of pillars for carrying items on shelves. Excellent pillars can identify the outcomes of goods storage in a business. So, how to calculate and identify the specifications of durable shelves? Below, racks provide you a quick introduction.
I. Strength and Instability Inspect
Because the pillar is the primary force component of the shelf, the structure is reasonably complicated, and the majority of them use cold-formed thin-walled steel (the recurring processing tension itself), and the load circumstance is likewise more complicated, specifically for high-level shelves with lots of layers and affected The load is big, so that the design of the column bores, the check is made complex, and the fairness of the value is straight related to the safety of the structure.
The hole type generally adopts inverted figure, rhombus or inverted trapezoid, so that the long hole of the column has a little angle with the vertical direction. After the hook is hung, it is immediately locked under the action of the gravity of the freight, and the hook is in surface area contact with the long hole of the column, The force is better, which guarantees more steady and safe use.
Nevertheless, the opening of the hook hole has a great effect on the bearing capability of the short column of the column. The bearing capability after opening is 70% ~ 95% of the bearing capability when the hole is not opened, and it has a greater effect on small-sized columns.
For that reason, under the facility of pleasing the load carrying capacity of the cross beam hook, the size and variety of hook holes should Supermarket Shelves be made as little as possible to enhance the overall load bring capability of the shelf. There are numerous long holes (hook holes) and round holes evenly distributed on the front side of the column, which are utilized to hook the beams and install safety pins.
