Braking device for the articulations of the supporting boom parts of an earthmoving machine

摘要

This invention relates to a device for reducing the reaction force in a positioning cylinder (5) of the supporting booms (1, 2) of an earthmoving machine. The device comprises a braking system (7) interconnected between the supporting booms (1, 2) of the machine which is operated during the time in which the positioning cylinder remains inactive, thereby unloading part of the reaction force of the cylinder, hence reducing the stress loads on the cylinder.
