The Closed End Hollow Guide Rail is a specialized elevator guide rail featuring a rectangular hollow structure with sealed (closed) ends. Designed to meet the demands of cleaner shaft environments and optimized strength-to-weight performance, this rail type is widely used in modern elevator systems requiring both durability and ease of installation.

Unlike standard hollow rails with open ends, the closed-end design prevents dust, moisture, and foreign matter from entering the rail cavity, making it especially suitable for high-precision, dust-sensitive, or long-term maintenance-restricted applications.

Specifications

In the early stage of elevator development (early to mid-20th century), the guide rail was basically solid rail. Simple in structure and high in strength, but heavy and difficult to install. This was suitable for low speeds and low floors at that time. Later, with the rise of high buildings and elevator speed, the need of “lighter, more stable, more energy-saving” emerged.

Hollow rail began to be put into application. It can reduce self-weight, improving the transport and installation efficiency, especially as high-speed elevators popularized. However, the hollow structure brings a side effect: the open end is prone to accumulating dust, water, oil, etc., affecting the service life and operational stability.

Based on the above limitations, some elevator manufacturers (especially in Asia and Europe) started to develop a new kind of guide rail—Close End Hollow Rail. It is characterized by a closed-end treatment at both ends of the hollow rail, which can be achieved by processes such as welded head, gland, and cast seal.

Recently, not all elevators are equipped with Close End Hollow Rail, it is more often used in customized elevators, special-purpose elevators, or high-end projects. Some Chinese, Japanese, and European elevator rail manufacturers have included it in their standard product line.

This is how Close End Hollow Rail comes in. If you have such requirements, why not take a look at our Close End Hollow Rails. They won't disappoint you.
