A crucial part of keeping your automated gate up and running is ensuring that it is well maintained. There are a few important factors concerning the maintenance of your gate to keep its condition up to standard.


General Maintenance Considerations


  • The wheels should be fitted properly to the gate and should move freely on the track from start to end without seizing.
  • The metal rack should be properly secured to the gate with a 2mm space between the rack and the pinion gear of the motor so that it does not press down on the motor at any time of its travel. Ensure that your mechanical stops are in place to prevent the gate from moving past the roller guides and falling over.
  • The stoppers that come with the gate motor kit are very important and may not be ignored when the motor is installed.
  • Use roller guides on the gate to improve its mobility and keep the gate steady while it is being operated.
  • Avoid ingress of insects, water, mud, and sand into the machine as they can damage the motor and cause unnecessary expenses in the future.
  • Do not grease any part of the gate as it will attract dirt and turn into grinding paste making a minor problem much worse.
  • Always keep the track clean and clear of any debris on or near its path.
  • Ensure that there is a furrow to channel water away from the track to prevent water pooling.
  • Confirm that there are no bends in the rail where the wheels may become jammed or resist movement.
  • Avoid any difference in track height from start to end.

A labor charge of R240.00 is required in advance, as it covers the cost of disassembling, testing, and evaluating the motor. The client has the choice to either receive a repair quote or authorize DMI Engineering to proceed with the repair without a formal quote. If the latter option is chosen, the client will receive a quotation via email or WhatsApp. Should the client accept the quote, the R240.00 labor charge will be deducted from the total repair cost. However, if the quote is not accepted, the client will forfeit the R240.00 labor charge.
