What's wrong?

The 2011-2016 Terex Aerial Devices are truck-mounted lifts used for power line construction and maintenance. At the boom tip, leveling sprockets are part of the structure that keeps the work platform level as the boom moves. That leveling system has to hold its position while a worker is in the platform.

On the recalled units, the welds at the boom tip leveling sprockets were not fused properly. The supplier's weld process left an incomplete bond between the sprocket and hub. When that weld cracks or fails, the platform can tilt unexpectedly instead of staying level.

An inspection done under the Terex maintenance manual is the warning sign path for this recall. That inspection can find a cracked leveling sprocket weldment before the platform tilts.

What's the safety risk?

A cracked leveling sprocket weldment can let the platform tilt unexpectedly. That tilt can make the user fall, increasing the risk of injury.
