Passengers were left hanging on the BuzzSaw ride at Dreamworld after a safety switch was triggered.
A Dreamworld spokesman confirmed the incident in a statement today.
"The Buzz Saw auto-stop sensor was engaged today," the statement said.
"Auto-stopping and resetting of rides is a regular and essential part of operations.
"It occurs for a variety of reasons, from sensor alignment to guest behaviour or weather.
"Guests are not placed in danger by auto-stops occurring. They are an essential built-in part of ride safety systems and manufacturer's specifications."
The thrill ride was previously closed in February 2015 due to a safety issue.
The drama comes just four months after four people were killed while riding on the Thunder Rapids ride at the Gold Coast theme park.
