RRC Retractable Rail Clamp is the obvious choice especially for modern high speed cranes. The RRC rail clamp is designed to clamp on both sides of a rail. They are spring set and hydraulically or electrically released. They are designed to release and retract fully above the rail head. This eliminates mechanical guiding means at rail level. All the features of these calipers allow reliability and low maintenance.

> Simple single cylinder solution that lifts all the critical components completely free of the rail.
> Serrated shoes protected from hitting the rail sides, no wear and tear to guide means, brake shoes as well as rail head itself.
> Top suspended mechanism allows for very low mechanism float forces, no need for lubrification points.
> Low friction mechanism stability device, allows for reliable setting of the rail clamp mechanism and positioning on a rail.
> Floating mechanism allowing compensation of horizontal ±30mm and vertical ±25mm rail deviation (more available upon request).
> Top mounted hydraulic cylinder with no rod connection, easily removable for quick maintenance and replacement.
> Clamp release, positioning and reserve stroke monitoring by proximity switches.
> As result of the above mentioned improvements, reliability and safety  are increased while maintenance costs are lower.

> Ship to shore cranes
> Automated stacking cranes
> Wide span cranes
> Ship loaders
> Rail-mounted material handling equipment
