Bridge crane "eating track" effect

(1) reduce the service life of the wheel.
Crane deformity cases, information on individual wheels to take ZG310 ~ 710 steel, through hardened disposal nominal wheel tread hardness HB300 ~ 380, hardening depth of not less than 15 ~ 20mm, can be applied to a decade or more times. But gnawing major  steel crane  rail wheels can only be used in 2012, and even some wheels just a few months, it must change, which affects the normal production and operation of enterprises.
(2) slow track wear.
Gnawing rail wheel lateral force generated can track position offset, increasing the wear track, the track will grind serious steps, until the replacement track.
(3) increase the running back out.
Gnawing rail traffic in operation will produce commensurate resistance, severe eating Road running resistance than normal  hoist gantry crane  operation increased by 1.5 to 3.5 times. Since running resistance increases, the motor and the transmission mechanism running overload operation, but also easy to make the drive system components such as shaft torsional bad.
(4) on the basis of beams, bridge effect.
Operation of the  sino hoist  rail gnawing inevitably produce a horizontal lateral force. The lateral force will cause lateral movement of the track, causing equipment vibration, resulting in a fixed orbit loose bolts, in addition, can also cause the entire road vibrations, which are affected in varying degrees beams, bridge structure solid.
