1500 kN (higher force on request)

These rail clamps are storm brakes suitable for high forces. They are self-blocking type; in case a force acts on the crane and tends to put the same into motion, they press on the rail sideways. This pressing gets stronger as the crane moves. The rail clamps can withstand horizontal force only. These clamps are guideless so, when the clamp is released, there are no parts touching the rail.
