The Coronial Inquiry into the death of four people at Dreamworld in 2016 has revealed that rides at the park could breakdown up to 20 times a day.
Park technician Matthew Robertson told the court that on busy days he could get 20 call outs in one day.
He explained that during the day Cindy Low, Kate Goodchild, her brother Luke Dorsett and his partner Roozi Araghi died the park’s electricians were “stretched thin”.

When the water pump failed on the Thunder River Rapids ride for the first time electricians at the park were dealing with another problem.
Mr Robertson said he asked the electrical department for advice on how to reset the pump.
When the pump broke down for the second time, Mr Robertson and another engineer reset it without notifying the electrical department.
Almost half an hour later the pump malfunctioned, leading to the fatal incident.
The inquest continues next week.
