Recall 23V340 covers 44 2021-2023 Altec Digger Derrick units with boom pressure limiters allowing lifts above rated capacity. Altec provides testing instructions free.
Altec is recalling 44 2021-2023 Digger Derrick units because the boom pressure limiter can let the boom lift loads above its rated capacity and hydraulic overload protection setting. Overloading the unit can make it unstable and increase the risk of injury; Altec dealers will complete the recall repair free of charge.

What's wrong?
The pressure limiter cartridge on the 2021-2023 Altec Digger Derrick is part of the boom lift hydraulic system. Its job is to limit hydraulic pressure so the boom stays within its rated lifting capacity. Hydraulic Overload Protection, or HOP, is the safety system that is supposed to react when a lift goes beyond the unit's allowed capacity.
On affected units, the boom pressure limiter was set higher than the design pressure. That incorrect setting lets the boom lift loads above the rated capacity and above the HOP setting. The problem traces to an incorrect production checksheet value, which means the part itself needs to be checked and reset to the correct pressure.
The load indicator gauge and pressure gauge at the operator's station still work. If the unit is lifting a load above capacity, the gauge rises into the overload region. During a boom raise capacity test, HOP can activate and point to the setting problem. No other warning sign indicates an improper boom pressure limiter setting.
Who's affected?
Covers the 2021, 2022, and 2023 model years, all tied to the same pressure limiter cartridge in the boom/crane/ladder equipment.

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?
Loads lifted above boom capacity can overload the unit, make it unstable, and increase injury risk. Know the load weight before lifting. If the weight is unknown, complete the boom raise capacity test and watch the load indicator or pressure gauge for overload. Repair is free at any franchised Altec dealer.
