Last week there was a serious incident concerning a new bridge crane on a refinery project my previous employer is managing. A new Total Tool bridge crane had been installed and was being connected and checked out by a factory technician. A manlift was working about 2 ft away. At some point the tech did something and the crane moved and kept going. He hit the emergency stop to no avail. The bridge crane traveled into the manlift crushing the tech against the man lift. An alert electrician working in the area on the ground seem what was happening and ran 80 ft shutting off a main to stop the unit. The JlG man basket was still intact. The crane tech somehow got tangled up between the handrails it was equipped with and the JLG and suffered broken ribs and has bleeding around his liver. Fortunately he is expected to recover. The last 4 days the unit has been under investigation by the refinery, the contractor, the crane manufacture, and the authorities. The crane was found to be wired correctly by the electrical contractor to the machine. Sunday( yesterday) all bridge cranes from this manufacturer were ordered to be shut down until they can be inspected. Starting to sound like an internal issue in the machines although no official report is out yet. If using one of these if nothing else check your Emergency Stop each day to insure it is working.
