An empty gondola cabin detached from a ski lift under construction at Copper Mountain on Monday and crashed to the snow-covered ground.

Nobody was injured in the incident involving the new lift, which is scheduled to open Saturday, the Summit County ski resort reported.

The incident happened at about 11 a.m., just after the gondola took off from the American Eagle base terminal, the resort said in a news release. The lift was not open to the public at the time of the malfunction, which happened during a testing procedure.

Leitner-Poma, the manufacturer and construction contractor, has reviewed the incident and concluded that “no critical components were damaged,” the resort said.

Copper Mountain is working closely with the Leitner-Poma team and the Colorado Passenger Tramway Safety Board to “ensure that, once completed, the American Eagle lift will operate safely and reliably,” the resort said.

The new American Eagle Lift, which carries a combination of 6-person chairs and 8-person gondola cabins, is replacing a high-speed quad chairlift at the resort. The new lift will increase uphill capacity by more than 40 percent, according to the resort’s website.

On Oct. 9 and 10, a Black Hawk helicopter and a crew from Leitner-Poma put up the lift towers. On Friday, the Colorado Tramway Board was on site for testing and inspections, according to the resort.
