Affects Terex XL4000 Digger Derrick · 1999–2012 — about 12 vehicles.
The hazard
On certain truck-mounted digger derricks, metal shims used on the hydraulic lift cylinder may be too soft and could compress under load. As a result, the rod eye casting could fail. This would allow the boom to fall, placing anyone near or beneath at risk of personal injury. Correction: Dealers will replace the existing shims and spacer with one hardened spacer.
