Overhead Crane Rail Clips Introduction

Crane rail clips are typically made of metal. They are designed to securely fix the rail laterally, while also allowing for some longitudinal movement and expansion due to temperature changes and other factors. The rail clamp can adapt to the large-scale, efficient, and diverse requirements of the crane; at the same time, the selection of different structural beams is also different. According to this, the rail clamps for cranes can be divided into bolted type, weldable type, and embedded type.
