  • Patent number: 10371176
    Abstract: A selectable flow divider drive system includes a hydraulic fluid reservoir and a plurality of drive motors in fluid communication with the hydraulic fluid reservoir. A hydraulic pump is connected between the hydraulic fluid reservoir and the plurality of drive motors and directs hydraulic fluid from the hydraulic fluid reservoir to the plurality of motors. The hydraulic pump is operable in a high flow condition and a low flow condition. A flow divider component is interposed between the hydraulic pump and the plurality of motors. The flow divider component selectively divides hydraulic fluid flow to each of the plurality of drive motors, where a flow divider of the flow divider component is sized for the low flow condition of the hydraulic pump. A bypass valve is disposed upstream of the flow divider that selectively bypasses the flow divider when the hydraulic pump is operated in the high flow condition.

  • Publication number: 20170341918
    Abstract: A stabilizer arrangement for mobile apparatus such as an access platform having a chassis with a functional component movably mounted thereon for movement between a rest position and a use position, comprises a stabilizer member movably mounted with respect to the chassis and having a ground-engaging portion, the stabilizer member being movable between a retracted condition in which the ground-engaging portion does not engage the ground and a deployed condition in which the ground-engaging portion engages the ground, the stabilizer member and functional component being mechanically interconnected such that, in use, initial functional movement from the rest position of the functional component relative to the chassis causes movement of the stabilizer member from the retracted condition to the deployed condition.

  • Patent number: 9206026
    Abstract: A longitudinal stability monitoring system controls a boom lift down speed for a lift vehicle. The lift vehicle includes a vehicle chassis supported on front and rear wheels respectively coupled with a front axle and a rear axle, and a boom pivotally coupled to the lift vehicle. The system monitors a vertical load on the rear axle and manages boom lift down speed based on the vertical load. Additionally, the system may manage the boom lift down speed based on both the vertical load on the rear axle and an anticipated operator demand according to a signal from an operator input device.

  • Patent number: 9187301
    Abstract: A self-propel accessory provides an easily attachable optional drive function for a platform device. The platform device is supported by a device frame including a wheel at a rear end and a post at a front end. The self-propel accessory includes an accessory frame attachable to the device frame via a bracket, a driving wheel connected to the accessory frame, a motor operatively coupled with the driving wheel, and a handle connected to the accessory frame. The accessory frame is pivotable between a disengaged position and an engaged position, and a weight of the platform device biases the accessory frame toward the disengaged position.

  • Patent number: 8887597
    Abstract: A split grip control lever is suitable for operating heavy machinery and includes a fixed base portion that provides secure operator support during operation of the machine. A movable upper portion is pivotable relative to the fixed base portion by the user's thumb and index finger to control operation of machine components. The movable upper portion and the fixed base portion preferably define a substantially continuous profile. Additionally, a control device is placed inside the fixed base portion of the grip, allowing for a shorter control shaft that pivots at or near the center of the unit. This arrangement facilitates control of the equipment.

  • Patent number: 8622170
    Abstract: A multiple envelope control system and method expands the operating capabilities of a lift vehicle. The vehicle includes a platform mounted to a telescoping main boom. The main boom is configured for lift/lower function and telescope function. The multiple envelope control system includes a selector switch for selecting between a plurality of capacity modes including at least a low load mode and a high load mode. A plurality of sensors are strategically positioned on the main boom to cooperatively define position zones of the platform. A control system determines in which position zone the platform located according to signals from the plurality of sensors. The control system controls an envelope of the platform based on a position of the selector switch. By strategically positioning the sensors to define the position zones, inexpensive switches, such as limit switches or the like, can be used, thereby reducing manufacturing costs of the machine.
