Product Description These rail clamps are storm brakes suitable for high forces: from 100 to 2000 kN. The capacity values are calculated with friction coeff. of 0, 25 or 0, 45 between breaking shoes and rail. Product Specification/Models Main advantages: Light Maintenance Breaking shoes are practically for the whole life, thanks to theself-blocking working principle (working only when wind force overcomes the gantry brakes capacity, with a force proportional to the wind force deducted the gantry brakes force). Jaws duration is very long (our experience is that jaws last is not less than 10 years, in some cases they have been changed after 25 years of life) minimising maintenance needs. Particular suitability to high speed cranes thanks to the free movement: the wide gap (seldom contacts) between guides and rails allows a long duration of guides. Efficiency The holding force does not decrease in the years, thanks to theself-blocking working principle. The wear of shoes is negligible and in any case does not affect on the holding force.Independenceof the holding force from the fatigue deriving from heavy duty cycle (the absence of springs renders this device suitable to the continuous open/close applications). Fast opening with law power: opening is made just rising up the light weight of the calliper (not working against strong springs and wasting energy). High tolerance: The automatic system allows verybig variation of rail width (on request, up to8 mm). Vertical allowance of the position respect the rail of ±12 mmis big enough to permit a fixed installation also in the middle of the seal beam (no wheels are needed). Easy installation: Any type of installation is possible, without need of "on trolley" realisation that requires further maintenance. Rail preservation: End user will take advantage from the negligible effects of wear, due to theautomatic blocking working principle Options: Customised realisations are available like integration of stowage pins in the clamp case frame, top flange, etc. Electric board are available
