Disclosed embodiments include power machines or loaders, and systems used on loaders, configured to augment the control of the loader to accomplish repetitive tasks. Also disclosed are methods of learning a task for augmented control of a loader, and methods of controlling a loader to perform a learned task to provide augmented control of the loader.

A retrieval arrangement for a ripper of a machine includes a bollard that is disposed towards a rear portion of the machine. The bollard includes a base that is disposed along a mid-plane of the ripper and connected to the ripper via a ripper carriage. A method for retrieving the ripper includes positioning a sling around the bollard, and pulling the sling using another machine such that the bollard is biased in the direction away from the ripper carriage.

The work vehicle includes an engine, a radiator; a hydraulic pump; a cooling fan that blows a cooling air to the radiator; a hydraulic motor which is driven by a pressure oil delivered from the hydraulic pump, and rotates the cooling fan; a directional control valve that switches a flow direction of the pressure oil from the hydraulic pump to rotate the hydraulic motor in forward and reverse directions; and a controller that controls the directional control valve so as to cause the repetitive operation of the forward and reverse rotation of the cooling fan to be performed at predetermined time intervals, in which the controller reduces the time intervals more than a normal time initially set when a relationship between the outside air temperature detected by the outside air temperature sensor and the refrigerant temperature detected by the refrigerant temperature sensor satisfies a predetermined condition.

A heavy-duty interactive (HDi) system may include a heavy-duty vehicle; a work tool installed on the heavy-duty vehicle; a memory that stores a plurality of patterns representing operation events for the heavy-duty vehicle; a first sensor affixed to the heavy-duty vehicle that collects first sensor data as the heavy-duty vehicle is operated; a second sensor affixed to the work tool that collects second sensor data as the work tool is operated; and a controller operatively coupled to the first sensor, the second sensor, and the memory. The controller may be configured to identify a heavy-duty vehicle operation event by comparing at least one of the first sensor data and the second sensor data with the plurality of patterns in the memory, and associate the work tool with the heavy-duty vehicle based on a comparison of the first sensor data and the second sensor data.

The invention concerns a trailer unit for use with a towing vehicle for transporting tracked constructional machines, such as excavators, said trailer unit including: a pair of wheeled carriages, respectively a left and a right wheeled carriages, adapted to be detachably connected to a pair of track frames, respectively a left and a right track frames, of a tracked constructional machine through first connecting means; a drawbar having a first end adapted to be detachably connected to a rear frame of the towing vehicle and a second end adapted to be detachably connected to a bottom frame of the tracked constructional machine through second connecting means.

A hydraulic excavator (1) includes a wireless authentication device (52) performing wireless authentication with a portable key device (51) and a vehicle body controller (48) for starting an engine (15) based on authentication by the wireless authentication device (52) and an operation of a start switch (12). The wireless authentication device (52) transmits a request signal within an authenticable range and performs authentication when it receives an ID code for authentication replied from the portable key device (51) based on the transmitted request signal. The vehicle body controller (48) prohibits driving of a hydraulic actuator (5E, 5F, 5G, 5H, 2E, 2F, 3A) when the portable key device (51) is outside of the authenticable range even if a gate lock lever (13) has been switched to an unlock position.

Shaker assemblies for dewatering slurries are disclosed. The shaker assemblies may include a positioning device which limits movement of the vibratory frame of the shaker assembly relative to a subframe when the vibratory frame is moved from a raised operating position to a lowered position. The positioning device may guide the vibratory frame as it is lowered from the raised position to the lowered position. In some embodiments, the shaker assembly includes a locking device for locking the vibratory frame to the subframe when the vibratory frame is in the lowered position.

A work implement for a work vehicle includes a boom having a chassis attachment end and an arm attachment end, an arm including a boom attachment end and a tool attachment end, and a work tool coupled to the tool attachment end of the arm. The boom attachment end is pivotally coupled to the arm attachment end of the boom. At least one of the boom and the arm includes a first portion and a second portion movably coupled to the first portion between a first orientation with respect to the first portion and a second orientation with respect to the first portion. At least one fastener is coupled between the first and second portions to selectively secure the second portion in the first orientation and the second orientation with respect to the first portion.

A ditch cutting and excavation spoil removal apparatus creates ditches and land contours while simultaneously removing excavation spoil from the banks of newly created ditches. The apparatus includes an excavation spoil collection box and an adjustable plow saddle that supports a plowshare. The spoil collection box has a vertically adjustable rectangular frame with an open front and bottom. The pivotally mounted plow saddle may be tilted upward and downward through the bottom of the excavation box frame for adjustment of the plowshare and, correspondingly, the depth of the ditch being cut. Excavation spoil is collected in the spoil collection box as the apparatus is moved along the ground surface and is removed by raising the spoil collection box.

A method for slowing transfer of a heavy work machine on a sloping base using a separate transportation device equipped with wheels, the work machine including a set of booms having at least one operating cylinder, an auxiliary device, and a brake including a brake surface, the method including the steps of towing the work machine using a transfer vehicle and the transportation device, supporting the work machine at least partly on top of the transportation device such that the crawler chassis is raised off the sloping base, and supporting the auxiliary device on the brake, the brake surface of the brake contacting the sloping base, using the operating cylinder to press the brake surface against the sloping base to create friction to slow transfer speed of the transportation device, and adjusting pressing of the brake surface taking place through the auxiliary device using the operating cylinder.
