Crane oiler dies when crushed between a crawler crane cab and track in California.

NIOSH 1997 Feb; :1-4
A 38-year old male crane oiler (victim) died after being crushed between the underside of the cab (house) of a 250-ton crawler crane and its track. The crane was in operation removing falsework (lumber used in concrete forms) from a wharf under construction. Prior to his movement, the oiler did not inform anyone that he was going to go under the crane. It is normal company procedure to notify the crane operator when entering a dangerous area around the crane. It was uncertain why he walked under the crane. When the crane operator swung the cab around after picking up some slings, the victim was dragged across the track of the crane by the cables and structural members on the underside of the crane cab. He was observed to drop on to the ground on the outside of the track. The CA/FACE investigator concluded that, in order to prevent future occurrences, employers should: 1. assure all personnel communicate their intentions to the crane operator when proceeding to an area of danger. 2. use a constant audio communications system to facilitate conversation, especially in noisy areas. 3. isolate or barricade the danger zone created by the rotating cab of the crane. Additionally, crane manufacturers should: 4. install sensors or active/intercessory warning devices in danger zones of the crane which must be entered by employees.
