  • Patent number: 9446700
    Abstract: A container handling system and method for a wheeled transport vehicle is disclosed that is capable of loading and unloading containers, particularly in locations where the overhead height is limited. A hinged tail member at the rear end of the elongated body (a/k/a tilt frame member) is rotated to the ground allowing the containers to be loaded and unloaded without rotating the tilt frame to its maximum height. A cable reeving arrangement, such as a dual reeving arrangement, can be utilized to load and unload the container.

  • Publication number: 20160068092
    Abstract: A vehicle hoist telescopic stage cylinder has first and second stage cylinders. A control is fluidly coupled with the first and second stage cylinders. The control valve moves fluid to and from the first stage cylinder independent of the second stage cylinder. Also, it moves fluid to and from the second stage cylinder independent of the first stage cylinder. The first stage cylinder extends and retracts independently of the second stage cylinder. The second stage cylinder extends and retracts independently of the first stage cylinder.

  • Publication number: 20040098984
    Abstract: A combination of an electronically controlled vehicle and a hydraulic system and method of operating same for monitoring and controlling the flow of hydraulic fluid in a hydraulic system having at least one hydraulic actuator is provided. An electronic control system (ECS) processes system parameters and information and allocates engine power and controls pump output while maintaining optimum engine performance. The combination of an electronically controlled vehicle and a hydraulic system prevents hydraulic overloads, avoids increased engine RPM, and reduces unnecessary wear and tear on system components while significantly reducing fuel consumption and the emissions of pollutants and noise during operation.

  • Patent number: 5954470
    Abstract: An improved compacting system, and an automated refuse vehicle that can employ this compacting system. Alternatively, the compacting system can be used with a stationary packer. The compacting system is capable of placing the packer ram, blade or panel into a creep mode in which, even if the maximum compacting force is applied, the packing ram will generally retain its position without reversing direction for a pre-programmed interval of time. The refuse vehicle also provides a fast-return cycle for an engaged container, and a series of "lock-out" zones to minimize the possibility of damaging the vehicle during automated use. Methods for using the compacting system and for operating the refuse vehicle also form part of the present invention.
