A Dumpmaster with adjustable tipping height

How to change the tipping height on an adjustable model of the Simpro Dumpmaster bin lifter.

An optional feature built into some Dumpmasters is the ability to adjust the tipping height of the machine. This feature can be requested from the factory at the time of order, and is popular in the waste industry as it means machines can be adapted for different situations as equipment leases roll over etc.

Procedure

  1. Lower the cradle to ground level.
  2. Remove the tipping track guide by undoing the bolts that hold the guide frame to the upright members.Remove the tipping track guide
  3. Release the bolt at the bottom of the track to allow the track guide to be moved up or down to the desired location.Release the bolt at the bottom of the track

  10. Remove the short section of chain between the two chain-link clips. This is called the 'link section'. The chain length is modified by replacing or changing this section.The chain 'link section'
  11. Now you need to prepare a new chain ‘link section' to insert. For every 300mm removed from the Dumpmaster tipping height, the chain ‘link section’ must be lengthened by 300mm.For instance, if the ‘link section’ is 125mm long and you are reducing the tip height from 1800mm to 1500mm, you must increase the length of the ‘link section’ to 425mm.Preparing a new chain 'link section'
  12. Now replace the 'link section' and reattach the chain-link clips.Replacing the chain 'link section'Reattaching the chain link clips
  13. Repeat all of these steps for the second chain, on the other side of the Dumpmaster.Repeat the procedure on the second lifting chain
  14. Before replacing the ram covers, test-run the machine to ensure that everything works correctly. Ensure that the ram stalls out on the ram stop at the correct stage of the tipping cycle.
  15. Replace the ram covers using an electric drill. The Dumpmaster may now be returned to service.Replace the ram covers using an electric drill
