Case Studies

5:45am: Quarry manager contacts on call technician because the pipework had blown off the 55KW water pump and filled the control box of the pump with water, after repairing the pipe they could not get the pump running again.

6:15am: On call technician gets to site and fills out the site-specific permit to work and Job safety analysis. After speaking to the site manager and plant operator the tech begins fault finding to see why the pump is not running.

Issue: The water had got into the control cabinet through the air vents and then into the Variable Speed Drive. This caused a short circuit internally in the VSD, which when powered up again, after resetting the circuit breaker, was no longer working. Our Tech liaised with our foreman who sourced a replacement drive, got it to site and worked with the tech to replace the drive and get the pump up and running again.

Outcome: The team were able to get the plant up and running again the same day, meaning that there was minimal downtime and production could continue that same day.

Above and Beyond: The tech also followed up and got a sheet metal cowl specially made for the control box vent so that if the pipe comes off again there is an extra layer of protection. The quarry manager was happy with the outcome and final product.

QUARRY WATER PUMP NOT RUNNING

Outcome: The team were able to get the plant up and running again the same day, meaning that there was minimal downtime and production could continue that same day.

GENERATOR PIT PUMP

Customer Requirements: They needed a submersible pump that was powered with a generator. It needed to be portable, so they could move it around to pump out water from the quarry floor and excavation sites.

Time frame: One month.

Installation specifics:

Automatic starting and stopping of the pump and generator so that the water level can be kept down outside of operating hours.
Manual control of pump.
Ability for the pump and control float to be disconnected safely from the generator by quarry staff so that they move it to a new site.
Installation of solar panel on top of generator so that the battery is always charged and ready to go.
Use of heavy-duty flexible cable for the pump so that it can be used in the harsh environment of the quarry.
Indication lights so that the quarry staff can easily see if the pump is running or in a fault condition.

Outcome: Customer now has a custom-fit-for-purpose pump set-up, that they can rely on to keep the water levels in their excavation area to a minimum and therefore accessible by their large machinery.

VIBRATING MOTOR SAFETY ISSUE

7:30am: Sand plant manager calls to say that they are having issues with their dewatering screen.

8:30am: Arrive on site after picking up safety equipment and PPE from our Matamata workshop. Speak with site manager and plant operator about the issue. Fill out site specific permit to work including JSA, identifying appropriate hazards. Call down to plant to begin fault finding.

Issue: One of the two vibrating motors on the dewatering screen was failing to stop when the plant operator pressed the stop button on the control panel. This was causing a safety issue, as the screen could not be stopped to work on other parts of the plant safely.

Technician: Our trusty Irishman found that this was due to a fault in the control contactor. The contactor was quite old and had overheated, causing it to fuse its internal contacts together. After isolating the power supply and locking it out, the Technician replaced the contactors (with spares from onsite) for both the vibration motors as the other one was the same age and would likely have the same issue soon.

Outcome: By 9:30 am the plant operator could get the plant up and running again safely and continue with the days production, avoiding expensive down time.
