The right way to choose industrial crane rails

June 08, 2023
Many customers need to do industry before the door, first thought to search the Internet search, the results of a search, look out a lot of company-related products, dazzling, do not know the kind of good quality, which is more suitable for their own, in the face of this The problem, as the customer chooses which product, is really difficult. For a long time, many customers have always talked with me about whether they can help them to distinguish between them and facilitate better selection. To answer this question, we must first understand the history of hanging rails.
In the past, industrial sliding doors basically used the lower bearing way. There were pulleys on the upper and lower sides of the door, the upper pulley played a guiding role, and the lower pulley played a load-bearing role. The biggest drawback of this load-bearing way is that the door is pushed and pulled up, once the lower rail Foreign objects (such as dust, sand, ice, etc.) can't move the door. This type of door pulley can easily rust and have a short life.
Later, some European companies brought their advanced upper load-bearing crane rails into China. The way to make industrial doors has undergone great changes. Imported hanging rails have been manufactured by molds according to strict European standards. Wheel rails and accessories are made of steel. A few years later, our domestic hanging rail crane company began to absorb advanced foreign technology, and after numerous tests and improvements, it finally developed a domestic industrial door hanger rail.
The initial domestic production of hanging wheel hanging rails, the process basically follows the European standard, the production of all the mold steel hanging wheel hanging rails. This kind of crane hanging rail system abandons the production concept of traditional industrial doors, pushes and pulls the door to the upper load-bearing, push and pull is easy, the force is scientific and reasonable, the production is easy, the cost is low, and the drawbacks of the traditional use are greatly reduced. After-sales service troubles.
In recent years, due to fierce market competition, in order to save costs, some companies have successively developed cast iron hanging wheels, which can be used as raw materials because of the use of scrap steel, and the prices are very low, the cost is low, and the production process is Differently, the cost is greatly reduced. The track was changed from the original full-height Q235 steel plate to the Q235 steel plate with different differences, although this process change reduced the cost and enhanced the competitive price advantage, but greatly reduced the quality of the hanging rail; this kind of cast iron crane The casting organization of the wheel is large and has many defects. The bearing weight is reduced, the service life is shortened, and unpredictable hidden dangers are generated at the same time, which increases the risk and decreases the safety.
In order to more clearly understand the difference between the mold steel suspension wheel and the cast iron suspension wheel, only the same weight-bearing 450kg suspension wheel is taken as an example. In the form of a physical map, it is more intuitive to display and compare the two suspension wheels, I believe we can give you some help.
