A self-propelled work vehicle is provided with work state estimation and associated control techniques. The work vehicle comprises ground engaging units, a work implement configured for controllably working terrain, and various onboard sensors. A controller is functionally linked to at least the one or more onboard sensors and configured to ascertain a first parameter or operation of the work vehicle, determine a work state of the work vehicle, based at least in part on respective input signals from one or more onboard sensors, and generate a control signal for controlling at least a second parameter or operation of the work vehicle, responsive to the ascertained first parameter or operation and the determined work state. The control signals may be provided for proactive adjustments to engine speed, movements of the work implement, movements of the work vehicle itself, etc.

The present invention is a slope work vehicle capable of traveling on a slope and performing work, the slope work vehicle configured by: a work vehicle main body that includes an operating seat; a traveling apparatus that is provided in the work vehicle main body and of which a control state changes depending on operations by a worker in the operating seat; a winch that is provided in the work vehicle main body; a traveling apparatus actuator that is connected to the traveling apparatus and drives the traveling apparatus; a winch actuator that is connected to the winch and drives the winch; a hydraulic pump that supplies oil to the traveling apparatus actuator and the winch actuator; a flow amount adjustment valve that is provided between the hydraulic pump and the traveling apparatus actuator; and a control means for controlling the flow amount adjustment valve, in which at least either of the control means and the flow amount adjustment valve is capable of adjusting the supply of oil so that the slope work vehicle does not fall from the slope when the slope work vehicle is positioned on the slope.

An object of the present invention is to provide a slope work vehicle that is capable of efficiently moving and working on a slope, and is highly safe.

A control system for a work vehicle, includes a controller. The controller includes a processor a memory device communicatively coupled to the processor, such that the memory device stores instructions that cause the processor to receive a first control signal indicative of performing relocation operations. Furthermore, the instructions cause the processor to instruct an actuator assembly to drive a chassis of the work vehicle in an upward direction relative to wheels of the work vehicle in response to receiving the first control signal, such that a front stabilizer and a rear stabilizer are disengaged from a ground.

A construction vehicle has a slewing ring on which a superstructure is rotatably mounted, and an undercarriage supporting the slewing ring. The undercarriage includes an upper chassis, having an upper propulsion device, that is rigidly connected to the slewing ring, and a lower chassis having a lower propulsion device that is mounted in a pivotable manner with respect to the upper chassis. Furthermore, a pivoting apparatus is provided in order to pivot the lower chassis relative to the upper chassis.

A track-type loader machine includes a main frame, laterally spaced track roller frames, an equalizer bar pivotally mounted to the main frame and attached to the roller frames, a work implement movably connected to the main frame by a plurality of linkages, and at least one cross-slope actuator which connects one of the roller frames to the main frame. The at least one cross-slope actuator is configured to tilt the work implement and the plurality of linkages in conjunction with the main frame relative to a pivoting axis of the equalizer bar.

Mobile apparatus comprising a main frame with displacing means; a sub-frame connected rotatably to the main frame; an operating arm connected to the sub-frame and comprising at least a first and a second articulation which are connected pivotally to each other, which operating arm can be transformed from an operating position to a transport position; drive members configured to move at least the first and second articulations of the operating arm; operating instruments controllable by a driver and provided close to a driver position on the sub-frame; measuring instruments configured to measure position data relating to a position of the first articulation and a position of the second articulation; and a control system configured to receive operational data from the operating means and position data from the measuring instruments; and configured to control the drive members in accordance with the received position data and the operational data.

The invention provides a trenching apparatus and a method of using a trenching apparatus. The trenching apparatus (100) may include a main body portion (10), trench cutting equipment (50) depending from the main body portion, at least two ground contacting units (16) arranged on opposed sides of the main body portion and on which the main body portion is supported, each of the ground contacting units being connected to the main body portion by a respective independently operable suspension assembly (20), the respective suspension assemblies being configured to compensate for unevenness of the ground thereby to maintain the trench cutting equipment in a desired angular orientation with respect to the vertical.

Construction equipment is provided that can include: a transport assembly operably supporting a platform, the platform having a leading edge opposing a rearward edge, the leading edge associated with a first direction of the transport assembly, and the rearward edge associated with a second direction of the transportation assembly; an operator cab above the platform and aligned closer to the leading edge than the rearward edge; an engine above the platform and aligned closer to the rearward edge than the leading edge; and a boom pivotably attached above the platform closer to the rearward edge than the leading edge, the boom being movable between a first position fully extended and a second position fully raised. Utility line pole placement and/or removal construction methods are provided that can include extending an extension assembly having a banana boom from a transport assembly to couple with a utility line pole.

Device and method for providing a vehicle surround view for a vehicle, which is located on a driving plane, comprising vehicle cameras, which provide camera images of a vehicle environment of the vehicle, a location-detection unit, which detects a change in location of at least one vehicle camera relative to the driving plane of the vehicle, and comprising an image data processing unit which projects the camera images provided by the vehicle cameras onto a projection surface to generate the vehicle surround view, which projection surface is adapted according to the detected change in location of the vehicle camera.

A loader work machine has a base frame including a cabin; a loader work apparatus attached to the base frame; and two traveling apparatuses supporting the base frame, and including: a track frame connected to the base frame; a drive wheel driving a traveling belt; front and rear idlers arranged in a front-back direction below the drive wheel and supported by the track frame; and one or more track rollers arranged between the front and rear idlers and supported by the track frame, the traveling belt stretched around the drive wheel, idlers, and track rollers.
