A beloved Utah businessman and father is dead after a bulldozer killed him and his youngest daughter in a freak accident.

Richard David Hendrickson, 57, and his 16-year-old daughter Sally died after a mini bulldozer slid off a tow truck and crushed their GMC pickup in Ogden Canyon on Saturday, July 6. His wife and two of their other children, also in the vehicle, sustained non-life-threatening injuries. The Hendricksons also have another daughter, who was not in the vehicle.

Hendrickson was the CEO and president of outdoor furniture company Lifetime Products. Vince Rhoton, executive vice president of Lifetime Products, tells PEOPLE that the family was spending time bonding together when the tragedy happened.

"They chose to come up the Narrow Canyon because it was such a beautiful day. Normally, they drive the other way around. But they came up the Arden Canyon because it was such a beautiful little scenic drive. And unfortunately, in that Narrow Canyon was where the very, very random accident occurred," he says.

Rhoton tells PEOPLE that the family had just taken a trip to the Pine View Reservoir, where they enjoyed activities like wakeboarding and water skiing.

Spending time with his family, especially Sally, is something Rhoton says Hendrickson always made a priority.

"She was different from the other three, and maybe more different from him than the other three. And he was looking for some way to have more closeness with her. And he figured out that she was interested in chickens," recalls Rhoton.

"And so, despite his many other responsibilities, both at church and within the family and at work, his hectic travel schedule, and all of that, he built a chicken coop and got some chickens," says Rhoton. "And he's not particularly having an affinity for farming and ranching, but he learned how to do it. And they worked on it together, and they raised chickens and sold eggs."

Rhoton tells PEOPLE that while Hendrickson was also "spectacularly talented" and an essential part of their business, what made him special was his unique ability to be "humble and likable."

His and Sally's death is something Rhoton says is a reminder to always "seize the day."

"Seize the day with, [and] be good to the people around you," he adds. "I think Rich would want me to say to people — I think he would want me to say to them to do your duty and be good to the people."

PEOPLE reached out to Utah's Department of Public Safety for comment.

Following the tragedy, a petition was launched on Change.org to control the types of vehicles allowed on Highway 39 in Ogden Canyon. "With the canyon passage offering little to no shoulder width in places, certain large vehicles pose a substantial risk to commuters' safety," it reads in part.

"Understanding the economic considerations, we advocate for a balanced approach, allowing commercial vehicles that are safe under these trail conditions, but restricting others that pose a too significant risk," it continues, adding, "The safety of hundreds of Weber County residents must take precedence over unrestricted vehicular access on Highway 39."
