  • Publication number: 20220259020
    Abstract: A vehicle lift includes a vehicle carrier and a pair of arms. The vehicle carrier can selectively raise and lower a vehicle relative to the ground. Each arm in the pair of arms is pivotally coupled with the vehicle carrier. Each arm in the pair of arms includes a first arm segment, a second arm segment, and an adapter. The arm segments have a telescoping relationship. The adapter is coupled with the second arm segment and is slidable along at least part of the length of the second arm segment. The adapter is capable of coupling with an accessory at a first vertical profile and a lower vertical profile to thereby allow the accessory to contact a vehicle to allow the vehicle carrier to raise and lower the vehicle.

  • Patent number: 10352332
    Abstract: A reconfigurable pump includes a housing with inlet and outlet openings. An inlet adapter is mounted on the housing and includes an inlet passage communicating with the inlet opening. The inlet adapter is removably mounted on the housing and can be removed and repositioned for reconfiguring the pump between low-inlet and high-inlet configurations. In a low-inlet configuration the inlet passage is generally aligned with an impeller rotatably mounted in the housing. A check valve comprising a flapper valve is provided in the low-inlet configuration and prevents backflow. The flapper valve is removable for configuration in a high-inlet configuration with the inlet passage located generally above the impeller level. The inlet adapter can readily be repositioned from outside the pump housing between its low-inlet and high-inlet configurations.

  • Patent number: 9433144
    Abstract: An orifice selector module for use with flow gauges in a sprayer environment. The orifice selector module is retrofit into existing or new flow gauge assemblies and is placed in line between the spray nozzles and the flow gauges. The orifice selector module includes a rotatable cap which rotates a rotor which in turn rotates an orifice plate which features numerous orifices of different sizes. These orifices can be switched on the fly manually by the vehicle operator to increase or decrease flow through a particular hose from a particular flow gauge.

  • Patent number: 9366389
    Abstract: A system and method for monitoring inefficient flow rates in a liquid-flow distribution system, such as that which is used in agricultural liquid application equipment. This may include blockages or punctures in a liquid line. The system generally includes a plurality of gauges for monitoring the supply line flow rate in a liquid application system which are monitored by a number of sensors. Immediate feedback is presented to the operator of the vehicle inside the cab. The system alerts the operator when a blockage, loss, or increase of flow rate has occurred in one of the liquid lines. The system may merely indicate that one of the lines is blocked, or the system may be more sophisticated such that it can indicate which line is blocked and adjust the flow in that line in an attempt to clear the blockage.

  • Patent number: 8083034
    Abstract: A lift control interface is operable to control and monitor a lift system. Each lift column in the system has such a lift control interface. The lift control interface allows a user to assign lift columns to a lift system. One or more of the assigned lift columns may be assigned to a column control group. The user may lock the selection of these columns. The status of the assigned, selected, and locked lift columns may appear on every lift control interface in the lift system. The user may govern operation of the selected columns in the column control group from a single control interface, such as any control interface at any of the selected columns. The lift control interfaces may include visual representations showing the relationships between the lift columns and a vehicle, such as with lift column icons being positioned around a vehicle icon.
