Abstract: At 12:00 p.m. on April 15, 2022, an employee was in the process of repairing a leaking hydraulic line on a 1998 Freightliner FLD120 sliding jib hooklift truck. The employee raised the dumpster in dump mode to access the damaged hydraulic line and turned off the engine. After disconnecting the damaged hydraulic line, the employee removed the second hydraulic line providing pressure to the sliding jib that was supporting the dumpster. With the loss of all pressure on the jib, the jib and dumpster slid towards the back of the truck due to gravity. The jib slid past the dump latches, which connected the jib to the dump section, and released the dump section. The employee was underneath the dump section when it fell and was struck on the head. The employee suffered head injuries and died instantly according to the Winnebago County Chief Deputy Coroner. The employee sustained crushing injuries to head, neck, and torso.
