A frame with brackets on one side to couple to lift arms and tilt operators on a machine such as an earthmoving vehicle. Brackets on the other side of the frame to detachably couple to the implement. A locking mechanism on the frame with operative handles to engage locking pins on the adapter with the implement between a release and locked position.

The disclosed embodiments relates an arrangement for tilting or turning a tool, the arrangement including at least one actuator for tilting and turning the tool, the actuator including at least a frame part adapted to be closed by a cover, the frame part and the cover enclosing a chamber portion (8) where a blade part having one or more blade gaskets is provided to divide the chamber portion into separate chamber spaces, the blade part being connected, at its first end, to a shaft, the second end of the blade part being adapted move reciprocally in the chamber portion, rotating the shaft at the same time. The joint between the frame part and the cover is sealed by a gasket contacting the blade gaskets.

Systems and methods can include stretching a stud of a hammer assembly by tightening, according to a preset amount, a plurality of fasteners, which can extend from a first end surface and/or a second end surface of a first nut threadedly coupled to the stud, against an upper surface of a body of the hammer assembly. The fasteners and the first nut can provide a clamping load for the stud upon completion of the tightening. The systems and methods can also include, after the stretching, tightening a second nut, which can be threadedly connected to the stud, toward a seat formed in the body of the hammer assembly; and further tightening the second nut, against the seat. The systems and methods can further include transferring the clamping load from the fasteners and first nut to the second nut.

A working tool mounting mechanism for a tractor, includes: an extensible cylinder that is disposed on a tip of a boom of a front loader of the tractor, and comprises a cylinder body and a rod slidable with respect to the cylinder body; engaging parts that are respectively disposed on the cylinder body and the rod, and are each movable between an engagement position and a release position with extension and contraction of the extensible cylinder, the engaging parts each engaging with a working tool detachably attached to the boom at the engagement position, and not engaging with the working tool at the release position; a cover that covers the extensible cylinder from one direction; and a frame that is fixed to the cover and restricts at least one of: movement of the cylinder body and the rod in an extensible direction exceeding a predetermined position with the extension and contraction of the extensible cylinder, and rotation of the extensible cylinder around an axial direction.

A joint orientation system is provided for a work vehicle having a chassis and an implement coupled to the chassis at a joint. The joint orientation system includes a first IMU positioned on a first side of the work vehicle relative to the joint and configured to collect a first IMU acceleration and a first IMU angular velocity and a second IMU positioned on a second side relative to the joint and configured to collect a second acceleration and a second angular velocity of the implement. A controller is configured to receive the first and second IMU accelerations and the first and second IMU angular velocities; determine a joint orientation correction based on IMU accelerations and IMU angular velocities; modify an estimate of joint orientation with the joint orientation correction to generate a current joint orientation; and output the current joint orientation for actuation of the implement.

A pin grabber coupler for coupling an attachment with an excavator having a housing at least between the plates; a rear receiving arch and a forward receiving arch formed by the spaced-apart plates for receiving a pin of the attachment; a wedge lock extending between the spaced-apart plates; and a main actuator driving the wedge lock into the rear receiving arch and retracting the wedge lock from the rear receiving arch. A locking system for locking or unlocking the wedge lock has a latch having a latch end, a lever end, and a pivot therebetween; the latch end engaging the wedge lock once the wedge lock is fully extended into the rear receiving arch; a biasing member coupled to the lever end and biasing the latch end towards the wedge lock; and an unlock actuator opposing the biasing member to disengage the latch end from the wedge lock.

A quick coupler circuit includes a cylinder to attach and/or detach an attachment to and/or from a construction machine by expansion and/or contraction, a flow pump to supply fluid to the cylinder, a valve through which fluid for operating the cylinder passes, a spool valve which includes a spool, to move along an axial direction, and to form a pressure at a node of the flow pump according to movement of the spool, an electronic proportional pressure reducing valve to control the spool valve, a switch to perform an ON/OFF operation, and a controller to output a control current to the electronic proportional pressure reducing valve in response to the operation of the switch. The controller is maintains control current which it outputs during the switch's ON operation for a predetermined period of time after the switch's OFF operation.

A construction equipment includes a work machine including a boom rotatable with respect to an upper rotating body, a rotatable arm, a rotatable bucket, a tilt rotator including of a tilting actuator, and a rotating actuator; an operation lever for outputting an operation signal corresponding to an operation amount of a driver; a location information providing unit for providing location information and posture information of the work machine; a work setting unit for setting a work area of the work machine, and providing plane information of the work area; and an electronic control unit for controlling the work machine according to a signal inputted from at least one of the operation lever, the work setting unit and the location information providing unit, wherein the electronic control unit controls the posture of the bucket so that the tip of the bucket contacts the work area.
