Skyjack has issued a service bulletin alert for a mast weld reinforcement for vertical mast lifts models: SJ12E, SJ16E, and SJ20E.
Lifts matching the affected serial numbers must be immediately removed from service until the mast section is repaired. The bulletin notes that a quality issue “with the weld between the mast base plate and mast vertical section” was identified. This issue may “result in cracks developing along the weld between the mast base plate and the mast vertical section, potentially leading to structural failure of the vertical mast causing serious injury or death.”
