REMOTELY ACTUATED AUXILIARY PRESSURIZATION SYSTEM

摘要

Abstract of the DisclosureThe present invention is a remotely actuated battery pow-ered, auxiliary pressurizing system for hydraulically actuated liftarm devices which system is driven independently of the principalpower source of the vehicle on which the hydraulic lift arm devicemay be mounted but utilizes the same hydraulic control system aswhen the system is being pressurized by the vehicle engine. Theinvention includes radio or light means to activate the batterypowered unit from the working basket or platform without the useof electrical conduits or pneumatic or hydraulic actuation lineswithin the lift arms and without in any way interfering with theconventional lift arms control system established in the workingbasket or platform. The remotely actuated battery powered pres-surizing system is mounted on the chassis of the vehicle and com-prises a battery operated motor pump assembly, control means forthe motor pump assembly which latter includes a receiver for thesignals transmitted thereto by the actuator on the work platform byradio waves or light rays. Provision is also made for actuatingthe system without reliance upon the transmission from the workplatform, for operating accessories and in event of emergency.
