Compact tool carriers having a loader mounted to a low-profile mainframe are disclosed. In some embodiments, the pivot points of the mainframe about which the loader is pivoted are low relative to the mainframe to reduce the mainframe size and to lower the center of gravity to improve the stability of the compact tool carrier during use.

A method of extending a reach of a material mover may include uncoupling and removing a first linkage that couples a work implement to an actuator on the material mover; uncoupling the work implement from one or more lifter arms; securing one or more extensions to each of the one or more lifter arms by (a) fastening, with a first fastener, an extension to a corresponding lifter arm, though a lifter-arm retention aperture, and (b) further securing the extension to the corresponding lifter arm with one or more additional fasteners adjacent the lifter-arm retention aperture and a top edge or bottom edge of an end of the corresponding lifter arm; coupling the work implement to the one or more extensions; and coupling a second linkage, which is longer than the first linkage, to the work implement and to the actuator.

The application relates to a double acting demolition device according to one embodiment for demolishing structures. The device includes a first crushing jaw for crushing operation, a first cutting jaw for cutting operation, and a combination jaw. The first jaws are separate jaws. The combination jaw is attachable to the first cutting jaw for constructing a second crushing jaw and to the first crushing jaw for constructing a second cutting jaw. The second crushing jaw is used jointly with the first crushing jaw in crushing operation and the second cutting jaw is used jointly with the first cutting jaw in cutting operation. In crushing operation, the first crushing jaw rotates around a fulcrum other than that of the second cutting jaw in cutting operation.

Systems and methods for monitoring an attachment, such as a breaker head, for a mining machine. The system includes a breaker head, a wireless identification tag, a sensor, and an electronic processor. The wireless identification tag is coupled to the breaker head and includes a tag memory storing an identifier of the breaker head and an antenna. The sensor is configured to generate measurement data associated with the breaker head. The electronic processor is configured to receive measurement data from the sensor, generate a notification based on the measurement data, and transmit the notification to the wireless identification tag. Additionally, the wireless identification tag is configured to store the notification. The notification can then be later retrieved from the wireless identification tag by various devices, such as a further mining machine or a reader device of maintenance personnel.

A control system and method of controlling a utility vehicle. The system may include a controller, an energy mode input associated with a user input request to select one of at least two power modes, an implement control input associated with a user input request to select a movement of an implement, a drive control input associated with a user input request to select a movement of a drive system to propel the utility vehicle, and an attachment type input to further refine the allowed operating power states. The controller is adapted to determine a change between the plurality of operating power states in response to user input requests to automatically optimize machine performance and efficiency. Each of the plurality of operating power states includes a maximum electric current output and a maximum speed output of the electric motor.

A work vehicle comprising a frame supported by a ground engaging device. A boom assembly is coupled to the frame. A boom cylinder is coupled to the frame and the boom assembly. An attachment coupler is coupled to a distal portion of the boom assembly. At least one tilt cylinder is coupled to the boom assembly and the attachment coupler. A primary attachment is coupled to the attachment coupler. A secondary attachment is coupled to the primary attachment. The secondary attachment comprises a stand configured to move between a standing mode and a stored mode, wherein the stand automatically moves to the standing mode when it is decoupled from the primary attachment.

A system has a hydraulic circuit configured to control a position of an attachment of the system and a control system configured to perform operations that include receiving an input indicative of a center of gravity of the attachment and controlling a flow rate of fluid directed through the hydraulic circuit based on the center of gravity.

The present invention provides a chisel for a hydraulic breaker that is installed inside the hydraulic breaker and struck by a reciprocating piston, including a chisel body having a shaft structure provided with a horn-shaped crushing portion at a lower end; and a stress distribution portion that is provided with a concave-convex form in which a plurality of grooves and protrusions are alternately formed on an outer circumferential surface of the chisel body in a longitudinal direction, and disperses a stress wave transmitted from an upper side to a lower side of the chisel body by striking of the piston and a stress wave transmitted from the lower portion to the upper portion of the chisel body by striking of a crushing portion to a crushed object.

An article handler for attachment to a front end loader, the article handler comprising a support body and a jaw assembly, the support body comprising a proximal end adapted for attachment to the front end loader, and a distal end adapted for attachment of the jaw assembly. The article handler may be adapted to handle, install, and dismount ground engaging tools (GET), such as teeth for excavating buckets.

A compaction unit configured for use in the compaction of a surface in connection with construction, excavation and other earth-working or related activities. The compaction unit may be configured as an attachment that can be interchangeably attached to various types of construction machines, operating machines and equipment (such as, but not limited to excavators, backhoes and the like). The compaction unit may be configured as single compaction device capable of performing any combination of (i) vibratory compaction, (ii) roller compaction, (iii) and plate compaction. These capabilities enable the unit to function as a single attachment that can operate as a roller compaction wheel, a vibrating roller compaction wheel, and a vibratory compaction plate depending on the desired application and requirements of the operator.
