Claims

[Scope of utility model registration request]

In an outrigger for a vehicle-mounted crane, in which an outrigger inner cylinder with a hollow rectangular cross section, with a jack fixed to the tip thereof, is telescopically inserted into an outrigger outer cylinder with a hollow rectangular cross section, which is suspended horizontally on the chassis side frame of the vehicle. , a side edge of at least one of the upper plate and the lower plate of the outrigger inner cylinder extends outward from the outer surface of one of the side plates of the outrigger inner cylinder to constitute an extension part, and the extension part forms an extension part. A gap is created between one side plate of the outrigger inner cylinder and one of the outer cylinders, and a gap is created on the outside of one side plate of the outrigger inner cylinder, below the extension of the upper plate, or above the extension of the lower plate in the direction of expansion and contraction of the outrigger inner cylinder. An outrigger telescoping drive device for a vehicle-mounted crane, characterized in that a rack is disposed along the outer cylinder of the outrigger, and a drive gear disposed on the outer cylinder side of the outrigger is engaged with the rack.
