How long home gantry crane rust

• For a long lay-off device , the rust is a very
  important job . For metallurgical cranes , gantry
  cranes and other cranes devices, metallurgical
  electric hoist how long they opposed it rust ?
• 1, the first device to be shut down when
  maintenance time, the entire surface of the
  device must be checked to ensure that each place
  has the best coverage of the surface of the film
  .
• 2, if in the course of examination , it was found
  that some local film metal structures appeared
  damaged , then must take these damaged areas
  cleaned and then coated with rust and other
  rust-proof paint for these areas. Protect it in
  the rain or snow , the metal surface is not due
  to weather problems and corrosion.
• 3, in the process of rust , do not overlook the
  active portion of the aluminum gantry crane , and
  this is very critical. For these parts , you can
  use numbers or numbers -20 -10 diesel for
  brushing , it can not only make the device easier
  to remove those corrosive substances , but also
  to make the metal surface to form a film , play a
  role against the cold .
• 4 , in addition to cleaning and lubrication of
  diesel , also coated with oil . The best choice
  for calcium-based or lithium-based grease for
  maintaining performance because they have a very
  good mechanical aspects of the role , and when
  using the device again , these oils will be
  better cleared.

Spring balancer Precautions

• First, when removing the balancer , the need to
  adjust the worm gear is rotated counterclockwise
  , double girder gantry crane so that other work
  can be carried out completely when the coil
  spring is in a relaxed state. Figure side rear

• Second, once a month to deal with balancer safety
  inspections, mainly to check contents are
• 1 , the fastener is loose.
• 2 , the upper and lower hooks or without bumps,
  cracks and defects.
• 3, the safety rope is reliable.
• 4 , shell and round tower should be no cracks, no
  serious wear and tear.
• 5, the safety devices are working.
• Third, the long-term placement , 15 ton overhead
  crane to unloading save , pay attention to
  moisture , avoid coil spring rust.
