At about 2:15 p.m. on September 3, 2021, employee 1 was assisting in the placement of the jib extension back onto the cradle position for transport. Employee 1 was standing on the work platform near the crane cab. Employee 2 was at the front of the crane where the jib extension was secured to the crane itself. Employee 3 was on the ground at the front of the crane. The crane operator was inside the cab. Employee 2 attempted to free the extension from the crane itself and knocked out the remaining pin securing the extension. This action caused the extension to fall from the crane. The falling extension may have struck employee 1 before he fell to the ground below the work platform. Employee 2 was knocked off the ladder and also fell to the ground. Employee 1 sustained a shoulder fracture and contusion.
