Altec Industries is recalling 3,089 2011-2014 model-year aerial devices because the boom may move unintentionally, the National Highway Traffic Safety Administration reports.
The recall affects L36A, LRV and LR7 aerial device models that were manufactured from June 1, 2011, to Sept. 30, 2014. They were also built with Texas Hydraulics upper boom drive cylinders.
The unintentional movement is linked to development of cracks in the cylinder base end lug casting, NHTSA said.
Altec dealers will inspect the cylinders for specific casting suspect lots. If both upper boom drive cylinders are not of the suspect lots, no further action is required.
However, if a cylinder is part of the suspect lots, technicians will look for visible cracks. If cracks are found, technicians will remove the unit from service immediately and replace the cylinder. If no cracks are found, the unit will be scheduled for magnetic particle inspection of the cylinder lug within 60 days.
These services will be performed free of charge. The recall is expected to begin on March 30.
Aerial device owners can reach Altec customer service at (800) 860-0183. Altec's number for this recall is CSN 611.
