GENERALDESCRIPTION
YFX series electro hydraulic wind proof gatewedge brakes are mainly
used in ports, docks, railways etc. for varioustraveling cranes
operating in the open air under operating conditions such asgantry
cranes, jib cranes and unloaders etc. for wind proof braking.
Meanwhilethey are also available to be applied with the anchoring
devices and wind proofropes for emergency and wind proof braking
when the cranes are under nonoperating conditions.
PERFORMANCES AND FEATURES
Compact structure and beautifully shaped.
Adapted with Ed thruster with good performances of action and
seal.The protection grade of enclosure is IP65.
Friction pads adopt advanced high friction resistant steel
withreliable performance.
Mainswaying hinged points are equipped with self lubricated
bearings with highefficiency of transmission, quick, flexible and
reliable action and long servicelife.
Manualrelease is convenient for maintenance.
Equipped with limit switch for indication of the workingconditions.
OPERATING CONDITIONS
Ambient temperature200C --- +500C.
Generally for use with AC power, 3 phase, 380 V, 50 HZ.
Sealevel altitude for application accords with GB755-2000 standard.
Theanticorrosive products should be adopted if such products are
eroded by rain andsnow in the open air or where there is corrosive
gas or medium.
TECHNICAL DATA
The wind proof capacity of each wind proofgate wedge brake (to be
converted into the force F of the horizontaldirection)
F = f xNWHEEL (NWHEEL is the wheel pressure. F isthe friction coefficient = 0.46)
Quantity whichshould be installed on the whole unit:
S = 2.5PW /F (PW is the wind load = CkhqA).See the crane designing norm.
