A Skytrak Telehandler toppled over in Jefferson Hills on Wednesday, injuring two workers.

Watch above for Sky 4 video from the scene.

Allegheny County 911 confirmed the fall occurred at 4:24 p.m. Sky 4 flew over the scene on Royal Court.

Video from Sky 4 showed the four-wheel telehandler, which is a type of forklift used to lift and move heavy items, toppled over in an attempt to install a swimming pool at a home.

Chris Bailey, owner of C.A. Bailey Excavating & Hauling, operated the equipment during the accident. His company is subcontracted by Skyview Pools to install in-ground swimming pools.

"When it toppled over, it almost felt like I was airborne for 10 minutes," Bailey said. "I was in the air, but inside the machine holding to the steering wheel. When it hit the ground, it threw me into the roll bar and through the window."

Bailey says the telehandler is 12,000 pounds, four times the weight of the swimming pool, and it was harnessed with four nylon slings.

However, he says one of the Skyview pool workers tried to redirect the pool toward the hole where it would be installed, but it swung back in the opposite direction, downhill, pulling the telehandler to the ground.

One person was transported by air, the other by ground.

“I was working in the basement. Me and my wife both work from home, and just all of a sudden heard a loud boom. I mean, it sounded like thunder. I thought there was maybe a storm in the area,” John Pisarek said. “I ran outside and saw the crane over and the guys on the ground and went over to help as much as I could.”

Pisarek said when he got to them, they were conscious and speaking.

“Hopefully, they’re both OK. Really good guys,” Pisarek said.

Occupational Safety and Health Administration said an investigation into the accident started Thursday morning, and it must be completed within six months.

Fines are pending the outcome of the investigation.

Skyview Pools & Spas issued a statement Thursday morning saying, "both men are doing well and resting. No other details to be released."
