Type HD Rail Clamp

High strength clamp for low speed rail applications. Provides lateral adjustability for fast and precise rail alignment.

View technical specification

Overview

The Type HD is used to secure sections of rail or crane lines in low speed applications, up to 200 feet per minute, such as ground track, elevated rail and overhead gantries. The rail clip features a rotatable central component that provides a high degree of lateral adjustability. It allows contractors to quickly and precisely align rails before securing them in position using standard hand tools. The clamps are manufactured from high strength SG iron, creating a reliable connection that minimizes maintenance requirements.

The clips are used in a variety of environments including train maintenance depots, industrial facilities, water treatment plants, dam/dockside cranes, automated warehouses and power stations. Three product variants are available, each in size 34"; to meet the diverse requirements of each industry and application (see product options below for more details).

Product Options

Type HD Soft
This clip does not touch the top of the rail, which allows the rail to lift slightly to accommodate rail wave, reducing stress and fatigue in the rail and clips.

Type HD Hard
Designed to hold the rail down tightly to prevent rail uplift. Like other Type HD rail clips, it is made from high strength SG iron.

Type HD Spring
An elastomer spring provides vertical restraint while still allowing the rail to lift with rail wave. It also reduces track running noise.
