SYSTEM AND METHOD OF PNEUMATIC SUSPENSIONS FOR LIFTING APPARATUS AND LIFTING APPARATUS COMPRISING SAID SYSTEM

摘要

System and method of pneumatic suspension for lifting apparatus and lifting apparatus comprising said system, enabling the adaptation of the suspension features of a cabin (1) of a lifting apparatus with respect to a chassis (3) of said cabin (1) depending on the load conditions and/or functioning of the lifting apparatus, wherein the system includes a number of pneumatic springs (7) located between the cabin (1) and the chassis (3), each pneumatic spring (7) with at least one chamber (9) by means of a conduit (8) which has a valve (10) configured to control the flow of a compressible gas contained in said pneumatic spring (7) and said chamber (9), such that the rigidity and damping capacity of each pneumatic spring (7) is controlled, insulating the cabin (1) from unwanted vibrations, in accordance with the conditions of the lifting apparatus at each moment.
