RECTRACTABLE RAIL CLAMP
The RRC Rail Clamps are designed to release and retract completely from the rail head, with no mechanical guiding means at the rail level. The release of the serrated shoes and mechanism retraction is achieved with a single, top-mounted hydraulic cylinder.
BENEFITS
Rail Clamp jaws fully released and retracted above the rail means that there are no mechanical guiding means at rail level at any speed which is a paramount for high speed, modern cranes. Serrated shoes are fully protected from hitting the sides of the rails contributes to less wear and tear. Mechanism compensates for the spring force loss, providing a constant designed clamping/holding capacity. Additionally, the effect of the vibrations on the rail clamp mechanism during crane travel is minimized.
AVAILABLE HOLDING CAPACITIES
- RRC-HS-SF from 50 kN to 1200 kN (SF Side Flange mounting)
- RRC-HS-TF from 50 kN to 700 kN (TF Top Flange mounting)
KEY FEATURES
Rail Clamp Mechanism: Spring set – Hydraulic or Electric release
- Rail Clamp shoes and mechanism retract completely above the rail head
- Mechanism weight is evenly distributed on four low friction bearings guided on a channel bar at the top of the rail clamp
- Low friction mechanism stability device
- Allows for the reliable positioning on the rail and setting of the rail clamp mechanism
- Top suspended mechanism allows for very low mechanism float forces
- Serrated shoes protected from hitting the rail sides
- Release of the serrated shoes and mechanism retraction done with a single hydraulic cylinder
- Top-mounted hydraulic cylinder with no rod connection
- Mechanism compensates for force loss, providing a constant designed clamping/holding force
- Caging bolts for mechanical release and maintenance safety
- Horizontal Float: ± 30mm
- Vertical Float: ± 25 mm
- Rail clamp mounted on the crane via a Side Flange
- Marine grade C4 paint system for superior corrosion protection
- Stainless steel removable cover with the inspection doors located on both sides of a rail clamp (Side Flange mount model)
- Inspection doors (Jeep style) with high quality rubber door latches and weatherproof strips
Electric linear actuator: Installed inside rail clamp (integral unit)
- No hydraulic oil, no possibility for oil spill / leaks
- Means for mechanical release in case of power loss
- Prewired Junction box
- Mechanically adjustable control of setting time at site
- Electric actuators are cleaner, easier to control, and require less maintenance than hydraulic cylinders
- Electric actuators are much more reliable than hydraulic equipment
- Eliminates fossil-based hydraulic fluids which are potentially toxic to humans, along with being harmful to the environment
