Rail Head Brakes

A similar style of Storm Brake, Rail Brakes incorporate a hardened tool steel shoe, which is applied directly to the top of a rail head by spring force. Rail brakes are sill-mounted with shims and plated emergency release bolts. The spring stack can be varied to deliver the required holding force. Lubrication points are provided at the head/shoe mating surfaces. Features and options include a release indicating/interlock limit switch, special alloys, coatings and custom mountings.

    Wheel Clamps and Brakes 0310

    Wheel Clamps and Wheel Brakes are used in many applications to insure the safety of your equipment.  Wheel Clamps wc_brakeand Brakes can be used on Container Cranes, Rail Cars, Tripper Cars, and Gantry Cranes.

    How Wheel Clamps and Wheel Brakes Work:

    Wheel Clamps and Brakes act directly on the wheel side flanges of rail mounted equipment.  They can be either spring applied (fail-safe) or pressure applied and they are intended for emergency stopping and holding.  Wheel Clamps and Brakes are similar to caliper brakes and are used for dynamic stopping and holding.  A toggle linkage compensates for lining wear to provide constant braking force.
