1. Patent RU 165312. Outrigger of lifting and transport machines

The patent relates to the field of lifting and transport engineering, namely to devices for support and anchoring (fastening) on the ground support surface, including weak soils and not strictly horizontal surfaces, metal structures of mobile lifting and often moved transporting machines during their operation. The remote support of the lifting and transport machine, including a bracket mounted on the machine frame, equipped with a lifting and lowering with a drive mechanism, a support device for transferring the load from the machine and the transported cargo to the ground, and an anchor device for perceiving the overturning and shear operational loads acting on the machine. It differs in that the working element of the anchor device is made in the form of a flat knife with a straight longitudinal axis, which, for installation in its working position, makes a piercing translational motion in the ground with the help of a drive cylinder, and the plane of the working element is inclined relative to the ground surface and in the working position the working element is under the contact area of the support device with the ground surface
