Remotely actuated auxiliary pressurization system

摘要

The present invention is a remotely actuated battery powered, auxiliary pressurizing system for hydraulically actuated lift arm devices which system is driven independently of the principal power source of the vehicle on which the hydraulic lift arm device may be mounted but utilizes the same hydraulic control system as when the system is being pressurized by the vehicle engine. The invention includes radio or light means to activate the battery powered unit from the working basket or platform without the use of electrical conduits or pneumatic or hydraulic actuation lines within the lift arms and without in any way interfering with the conventional lift arms control system established in the working basket or platform. The remotely actuated battery powered pressurizing system is mounted on the chasis of the vehicle and comprises a battery operated motor pump assembly, control means for the motor pump assembly which latter includes a receiver for the signals transmitted thereto by the actuator on the work platform by radio waves or light rays. Provision is also made for actuating the system without reliance upon the transmission from the work platform, for operating accessories and in event of emergency.
