<p>S P E C I F I C A T I O N SHOCK-ISOLATED ELECTRIC ACTUATOR FOR MOVING A HARVESTING MACHINE HEADER The improvement incorporated by a harvesting machine is a shock-isolated electric actuator interconnected between the header and the frame of the machine and being operable to move the header between field operating and transport positions relative to the frame. Electrical circuitry is provided for interconnecting the actuator to a source of electrical power and a switch is disposed in the circuitry for controlling the transmission of power to the actuator and thereby the operation of the actuator. Also, the electric actuator at one end is operably connected to the header and a shock isolator assembly interconnects the other end of the actuator to the machine frame. The chock isolator assembly includes a support bracket rigidly mounted on the frame, an elongated member connected to the other end of the actuator and a shock absorbing body formed of resilient rubber-like material supporting the elongated member and, in turn, itself being mounted to the support bracket. Any shocks or impacts against the header and transmitted to the actuator are absorbed within the resilient material of the body.</p> |
