- Summary
- Structural cracking has been observed where the primary leveling cylinder mounting pin is welded to the lower boom side plate on LS 40/45/55 aerial devices. Failure of this connection could disable the hydraulic platform leveling system. Altec has developed a kit to reduce the relief pressure of the hydraulic leveling circuit. This will prevent damage to the leveling cylinder mounting pin weld joint by reducing the weld stress. Altec has also developed a kit to repair the lower boom if the side plate has cracked. Altec requires the inspection and repair be completed on the affected units by the next annual preventive maintenance interval or within one year of receipt of the SIL.
