Electric hoist inspection and maintenance are also cycle

Product inspection and maintenance are cycle electric hoist as small light lifting equipment is no exception,lever hoist not only to maintain but also to master the correct method hoist inspection and maintenance cycles can extend its life to ensure efficiency.
      Electric hoist parts more, different techniques for the various components of the characteristics of the actual work will be maintenance, inspection cycle is divided into weeks, months, years, the specific content of each period are as follows:
      A weekly maintenance and check again:
      1) Check the nut on the brake, the opening pin, the positioning plate is complete, loose, the lever and the spring no cracks; brake is reliable braking, the brake pad to open the opening when the brake should be less than 1.0mm and the brake wheel clearance distance should be equal on both sides of each axle pin may not have stuck.
      2) safety switches and limit switches are accurate, flexible and reliable work, especially electric hoist up limit is reliable.
      3) on the drum and pulley rope wound is normal,manual hoist without off-tank, channeling, knotted, twisted and so on.
      4) Check the hoisting mechanism coupling closures fastening screw is loose, the shortage.
      5) agencies transmission is normal, no abnormal sound.
      6) Check all lubrication lubrication condition is good.
      2, the monthly inspection and maintenance, inspection and maintenance, we cover the content but also have weekly:
      1) Check the wire rope for wear, if there is broken wire and so on, check the wire rope lubrication conditions.
      2) Check the hook for cracks, wear and tear of its dangerous section does not exceed 5% of the original thickness; hook nut locking device is complete.
      3) Check the motor, reducer bolts fastening the base and individually fastened.
      4) Check the gearbox lubrication conditions, the oil level should be within the specified range, measures should be taken against oil leakage sites prevent leakage.
      5) Check the balance at the rope pulleys for wear on pulleys and pulley shaft lubrication.
      6) Check the pulley position, to see whether it flexible, without damage, cracks, particular attention to the wear of the fixed pulley shaft.
      7) Check the brake wheel, uneven surface of its work should not exceed 1.5mm, brake wheel should not have cracks, its radial runout should be less than 0.3mm.
      8) Check the coupling, which should not be on the key and keyway damage, loose.
      9) Check the size of the vehicle operating conditions, should not have gnawing rails, three fulcrum,hoist and trolley when the pendulum starts and stops and so on.
      10) on the hoist to conduct a comprehensive clean, remove dirt on it.
