Altec AH125 Recall 20V708: Aerial Boom May Unexpectedly Lower, Risking Injury

NHTSA campaign 20V708, reported November 17, 2020, 13 vehicles potentially affected.

What this recall means for you

Some Altec AH125 and AH150 articulating aerial devices may have an incorrect counterbalance valve installed in the main lift cylinder. At certain boom positions, this valve can open because cylinder pressure exceeds its setting.

If one of the hoses between the cylinder and the external counterbalance valve manifold fails to hold pressure, the boom could unexpectedly lower, increasing the risk of injury to operators and people working near the device.

Altec will notify owners, and authorized dealers will install the correct counterbalance valve where needed, at no cost to the owner. Owners can contact Altec customer service at 1-877-462-5832 (reference CSN 784) and should check their vehicle's VIN for open recalls.
