When installing formed guide rails, which of the following is correct?

When installing formed guide rails, it is essential to ensure that the brackets are properly aligned and secured to maintain the elevator's safety and functionality. The correct approach states that the brackets do not require any shims.

This understanding is based on the design and construction of formed guide rails, which are engineered to fit precisely into their corresponding brackets without additional shimming for support. Proper installation of the brackets usually involves ensuring that they are level and securely fastened, which negates the need for shimming.

In contrast, using shims can sometimes introduce misalignment issues or create unnecessary gaps, which could potentially compromise the stability and operation of the elevator system. Therefore, in many modern installations, including those involving formed guide rails, shimming is not considered necessary, ensuring a clean and effective fit.
