Abstract:
Articulated operating arm (100) on which one or more implements are or can be mounted, comprising substantially three articulations (101,102,103) which are pivotally connected to each other, which substantially three articulations comprise a first articulation, a second articulation and a third articulation which is intended for connection to the one or more implements, which second articulation is pivotally connected at a first end to the first articulation an at a second end to the third articulation, wherein the substantially three articulations are rotatable adjacently of each other in order to form a shortened arm, this such that during the rotation a mechanical locking of the third articulation occurs between the second and the first articulations.
Abstract:
Articulated operating arm including at least a first articulation and a second articulation, which first articulation is connected for pivoting around a first axis to the second articulation. A control member is operative for the purpose of moving the second articulation relative to the first articulation, which control member has a first end coupled to a coupling structure which is configured to connect this first end for pivoting around a second axis to the second articulation, which second axis is parallel to the first axis. The second articulation includes an elongate structure and a wing; which elongate structure has a first end for connection to the first articulation, a second end and a side wall between the first and the second end; which wing is attached to the elongate structure. The coupling structure has a first end supported at the side wall and a second end supported by the wing.

Abstract:
A mining machine comprising a power monitor sensing power consumption of the mining machine during a select time period to generate power consumption data; a sensor sensing payload of the mining machine during the select time period to generate payload data; and a monitoring module. The monitoring module including computer readable media for comparing the power consumption data and the payload data to generate shovel efficiency data, and outputting the shovel efficiency data.
Abstract:
The present invention relates to a work machine, in particular to an excavator, having a boom, an extension element and a piece of working equipment, wherein the extension element is attached to a pivotal connection axle of the boom via a first gimbal mounting and bears the piece of working equipment, wherein the piece of working equipment is attached to a pivotal connection axle of the extension element via a second gimbal mounting.
Abstract:
A canopy installation member for installing a canopy is firmly fixed on a rotation table frame. A rotary working machine having a working machine installed at the front of a rotation table frame (5), an engine (8) mounted on the rotation table frame (5), and a canopy detachably installed at the rear of the rotation table frame (5), wherein the engine (8) is placed and fixed on the rotation table frame (5) with a horizontally placed frame-like engine support member (31a, 31b) interposed between the engine and the frame, and a canopy installation member (32a, 32c) is raised at one side of the engine support member (31a, 31b).
Abstract:
A swing type working vehicle, wherein a space at the foot portion of an operator can be increased when pedal operation is not required. A step is installed on the front part of a swing table frame, and pedals for operating hydraulic actuators are disposed on the step. The base parts of the pedals are supported so that these pedals can be swung forward and backward. When the pedals are swung backward, they are brought into contact with the operating members of the hydraulic actuators to disable the operation, and when the pedals are swung forward, they are held in the state of being brought into contact with the step.
Abstract:
Bosses extending in the boom width direction are provided in a front end part of a main boom body rotated upward, and hooks opening downward are provided in a base end part of a front boom body rotated downward. In a state that the bosses and the hooks are engaged with each other, a scooping action is performed so as to match pin holes thereof. The above hooks and the bosses are arranged so as to satisfy a condition that in a state that an angle between both boom bodies is a maximum angle at the time of work, the hooks and the bosses are moved away from each other and a distance between the hooks and the bosses is increased as the angle is reduced from the maximum angle.
Abstract:
Disclosed is a mobile apparatus for earth moving and other operations, such as lifting and displacing loads. A frame is displaceable on wheels. An articulated operating arm is supported by the frame for carrying an implement, for instance a container, a digger bucket or wrecking hammer. One or more motors drive the wheels and move the operating arm. The operating arm consists of at least three articulations connected to each other for mutual pivoting on a lying axis. A control member such as a hydraulic cylinder is arranged between each pair of articulations. The third articulation has a greater length than the second one, such that when the articulations are folded against each other, the implement can be freely used at the free end of the first articulation. Thus, the last articulation can be transformed from an articulated arm into a single lifting arm.
Abstract:
A parallel support member is constituted by a pair of links that are respectively arranged on the left and right sides of a second boom. These links are connected between a first boom and a third boom. Thus, the second boom is moved to the left or right side by an offset cylinder. In this case, when one of the links pulls the third boom the third boom, an arm, and a bucket can be moved toward the left or right side of a vehicle body to be parallel to the first boom. At this time, the links accept a force exerted in the pulling direction, but need not receive a force exerted in the compression direction, so that the cross sectional areas, the weights of these links can be reduced.
