Abstract: A flexible connection between the crane base of a truck-mounted loading crane and a transverse support bridge mounted on the vehicle chassis frame, said connection comprising a support arm formed on the crane base, the free end of said arm formed as a hub into which is inserted an elastic joint member secured to said bridge, said arm end engaging with some play in a lateral groove in the bridge.

Abstract: In support legs intended for mobile cranes and comprising telescopically displaceable jib sections, an arrangement permitting maximum jib length while retaining complete stability of the crane, said arrangement including a support arm extending in the direction of the displacement of said jib sections and supported at one end by the crane base and abutting at its opposite end against the inner jib section, said support arm additionally provided with means to limit the degree of extension of said inner jib section.

Abstract: A means to damp the oscillating movements of a hoisting device suspended in a link the upper end of which pivotally mounted about a first horizontal shaft on the outer end of a crane jib and at the lower end of which the hoisting device is pivotally mounted about a second horizontal shaft. A sector-shaped brake disc is mounted at the upper articulation point, the centre of said disc being situated in or close to the centre of said first shaft. At least one brake shoe is provided at the crane jib and arranged to be pressed against the disc at a distance from said first shaft, whereby the desired damping effect is obtained.
