Constructive disposition applied in cranes type beam

摘要

The following summary must describe a constructive provision applied in crane type beam, which has an auxiliary arm (15).With a slewing mechanism of axes parallel to the other joints of the crane, and that such a mechanism is formed by a rod.Equipped with bearings and axles linkage actuated by a hydraulic actuator (20) fitted at the end of the second arm (13) of the crane which in turn is connected to the first arm (12).Which is based on the rotating support column (9) of the crane.The rod has two ends, and one of them is attached to the second arm (13), through a mechanism of connecting rods (17) driven rotationally.Through a hydraulic actuator (20) able to articulate it with or without load, from the retracted position until it reaches the maximum opening, and limiting the course of the actuator.At the opposite end is the accessory coupler type quick coupling is reversible, allowing the coupling of functional devices, which vary according to each application.
