What's wrong?
The vertical cylinders on 2013-2014 Terex Digger Derrick and Aerial Devices trucks are part of the outrigger system. The outriggers extend to the ground and brace the truck while the aerial device or digger derrick lifts people and equipment for power line work. The cylinders use hydraulic pressure to lower, hold, and raise those supports.
On affected trucks, the cylinders were assembled without an orifice, a small restriction that controls hydraulic flow. Without that orifice, the outrigger valve can chatter under load, which creates excessive wear and damage inside the valve. Once the valve is damaged, the vertical cylinder no longer holds its position as intended, so the outrigger slowly drifts and the unit settles during operation.
Owners and crews can listen for excessive noise when an outrigger is lowering. If the valve is already damaged, the visible sign is slow outrigger drift while the truck is set up and working.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
An outrigger that drifts can let the platform settle during operation, which can make the platform fall and seriously injure occupants or bystanders. Excessive noise while lowering the outrigger or visible settling is a warning sign. Stop platform use and call Terex for repair guidance. Repair will be free at any franchised Terex dealer once available.
