Abstract

A mobile crane includes an undercarriage with a middle section and two parallel crawler carriages; a superstructure on which a boom is mounted, the superstructure being connected to the undercarriage by a rotary joint; two longitudinal outriggers connected to the undercarriage and extending in the longitudinal direction between the crawler carriages; and two transverse outriggers connected to the undercarriage and extending outside the crawler carriages. One of the longitudinal outriggers has an end with a transverse beam supported by spaced apart outrigger cylinders which provide an extended tipping edge to further stabilize the crane.
