Abstract: Power machines such as excavators with control inputs that are configurable to control various functions on the excavator. In some modes, selected control inputs are manipulable to control the position of a lift arm, bucket, and house position. In other modes, the same control inputs are used to control travel and an implement on an undercarriage.

Abstract: A hydraulic brake mechanism for use in hydraulic systems to provide braking of a hydraulic motor is disclosed. The brake mechanism provides proper braking under a range of operating conditions, including (1) the start of flow from the pump to the brake and motor and braking is not desired; (2) operating conditions in which constant flow is provided from the pump to the brake and motor and braking is not desired; (3) operating conditions in which abrupt decreases of flow from the pump to the brake and the motor occur, for example where flow is reduced due to being drawn by another work element or hydraulic load, but under which a reduced supply flow is still present and braking is not desired; and (4) operating conditions in which the hydraulic flow from the pump to the brake mechanism and the motor is shut off completely and braking is desired.

Abstract: A light system includes a plurality of light towers including a first light tower and a second light tower. Each light tower include a light source, a rechargeable battery operable to provide electrical power to the light source, and a control system programmed to control the flow of power to and from the rechargeable battery. The light system further includes a power/network cord electrically connecting the first light tower to the second light tower, a power source, and a power recharge cord arranged to electrically connect the first light tower to the power source. The power recharge cord is operable to provide electrical power from the power source to the first light tower and from the first light tower to the second light tower via the power/network cord. Each control system is programmed to selectively activate the power source to initiate a recharge cycle for the respective rechargeable battery.

Abstract: Disclosed are power systems, and power machines employing the power systems, having dual in-line pumps configured to supply hydraulic fluid to respective left and right side travel motors of the power machine. In some exemplary embodiments, pump pintle arm controls and a single centering mechanism for the pintle arm controls are provided. The single centering mechanism is configured to center the pintle arms for each of the two pumps. Also in some exemplary embodiments, a mechanical control linkage configuration allows the separate pump pintle arm controls to be positioned on a side of the pump substantially one behind the other. This allows hydraulic connections to the pumps to be placed on top of the pump assembly, improving the routing of hydraulic hoses in the power machine.

Abstract: A method of controlling a lift arm actuator and a tilt actuator to control positioning of an implement carrier coupled to a lift arm of a power machine. An activation signal is received from an enabling input device. A lift arm control signal is received from a lift arm control input commanding movement of the lift arm. The lift arm actuator is controlled responsive to receipt of both of the activation signal and the lift arm control signal to move the lift arm to a target lift arm position and to move the implement carrier to or maintain the implement carrier at a target implement carrier orientation relative to a gravitational direction.

Abstract: Track assemblies for power machines include a track frame, including a primary portion and a second portion moveable with respect to the primary portion. A plurality of rollers are positioned along the primary portion of the track frame relative to each other and the center of gravity of the power machine to provide an improved capability to compensate for vibration generated as the power machine moves over a support surface. In some aspects, a portion of a tensioning idler is positioned within a cylinder defined by one of the plurality of rollers.

Abstract: A movable electrical generation system includes a generator operable to produce a supply of electrical energy, a prime mover operable to drive the generator, and a first fuel supply selectively deliverable to the movable electrical generation system in a first pressure range. A second fuel, different from the first fuel is selectively deliverable to the prime mover in a second pressure range. A controller is operable to automatically deliver the second fuel to the prime mover in response to the first fuel having a pressure outside of the first pressure range.
