Claims

[Scope of utility model registration request]

A wire pulley was placed on the middle boom and stretched between the base boom and the fly boom so that the fly boom was extended and contracted in conjunction with the operation of a telescope cylinder interposed between the base boom and the middle boom. In an aerial work vehicle or the like equipped with a telescoping boom in which a boom telescoping wire is hung on the wire pulley, an oil pot storing lubricating oil is placed in the middle boom, and an oil pot storing lubricating oil is placed in the middle boom, and the oil pot is equipped with a retractable boom in which a boom telescoping wire is hung on the wire pulley. 1. A lubricating device for a boom telescoping wire, characterized in that a coating roller is provided that can apply the lubricating oil to the wire.
