What types of crane rail clips are there?
The main types of crane rail clips are welded and bolted, which are further categorized by features like adjustability and low-profile design. Welded clips are for high-strength, permanent installations, while bolted clips are more convenient for medium-duty and temporary applications. Adjustable clips are designed for precise alignment, and low-profile clips are for environments with tight clearances.
Types of crane rail clips
Welded crane rail clips: These are used for heavy-duty, permanent installations and are known for their high strength.
- Components: Typically include a weldable base, upper clip, rubber tongue, bolts, and flange nuts.
- Best for: Applications in heavy-duty industries like steel and aluminum manufacturing.
