Abstract

1,173,791. Mobile cranes. RICHIER SOC. ANON. 8 Feb., 1967 [8 Feb., 1966], No. 6096/67. Heading B7J. A mobile crane comprises a wheeled turntable chassis 2 provided with stabilizing legs 5a, 5b pivoted on axes 9 so as to be retractable to the dotted line position in Figs. 1 and 3 in which the upper surfaces of the legs lie in a plane and form a base on which loads may be supported. The legs 5b are in two parts 6, 7, pivoted at 8 and controlled by a linkage 15, 16, 17, and are operated by hydraulic jacks 13, 14; alternatively, all the legs are telescopic and operated by individual jacks. Jacks 18 are provided on shoes 19. In other embodiments, free play is provided between the shoe and the axis 9, by forming the leg in two parts hinged together about a horizontal axis and providing stops, or a pin-and-slot connection, or by forming the leg in one piece and mounting the shoe on a flanged spindle capable of free vertical movement through the end of the leg.
