NIOSH 1998 Apr; :1-6
On October 8, 1997, a 56-year-old truck driver (the victim) was crushed when a crane tipped over and the crane's boom landed on the cab of the truck in which he was sitting. The victim, who was hauling excavation material from a 16-story office building construction site, was sitting in the cab of the parked truck waiting to access the excavation site for loading. The mobile all-terrain crane had been set up in preparation for off-loading the components of a tower crane which was scheduled to arrive on site at a later time. The crane operator began to move materials and equipment to make room for off-loading the tower crane components. The crane operator had set up the crane with the left side outriggers fully extended and down, and the right side outriggers down only. The crane operator lifted an empty concrete bucket over the rear of the crane and swung the load around toward the front, over the right side. When the lift had progressed to the right front quarter of the adjacent truck, the crane operator began to lower the concrete bucket. When he did so, the crane began to tip. The operator attempted to lower the load to the ground to maintain stability but was unable to respond quickly enough. The crane tipped over and the boom struck the truck's cab directly over the driver's position. The victim was trapped and crushed in the cab. Workers on site notified 911 and rescue personnel responded immediately; however, rescue and first aid attempts were not possible due to the damage to the truck's cab and the crane's boom lying on top of the victim. The victim was recovered about 4 hours after the incident when other cranes were used to lift the boom from the truck cab. The victim was pronounced dead at the scene. NIOSH investigators concluded that, to prevent similar incidents, employers should: Ensure that cranes are operated within their limits of stability as determined by the manufacturer-supplied capacity charts. Ensure that crane set-ups are optimized with out-riggers fully extended when possible to provide the maximum lifting capacity.
