  • Dipper door retarding mechanism
    Patent number: 8732994
    Abstract: A retarding mechanism for continuously retarding the swinging movements of a dipper door comprises a hydraulic braking assembly mounted to the dipper bucket and operatively connected to the dipper door via at least one braking arm pivotally mounted within the braking assembly and at least one linking member pivotally mounted to the dipper door. The retarding mechanism continuously retards the opening and closing movements of the dipper door by controllably braking or slowing the at least one braking arm using the compressive action of at least one hydraulic piston mounted to the braking assembly.
