A working machine includes a lower body, a turning body, a turning manipulating member which turns the turning body, a hydraulic motor which rotationally drives the turning body, a brake device which brakes the hydraulic motor, a main hydraulic source which supplies hydraulic oil to the hydraulic motor, and a direction control valve which controls a flow direction of the hydraulic oil according to the manipulated variable of the turning manipulating member, in which in a state where the hydraulic motor is braked by the brake device based on a manipulation of a brake manipulating member, when the turning manipulation is performed by the turning manipulating member, a brake applied to the hydraulic motor by the brake device is released with respect to turning in an indication direction indicated by the turning manipulation such that the turning body turns in the indication direction.

A mobile crane has an undercarriage, a superstructure arranged on the undercarriage, a slewing gear by which the superstructure may be rotated relative to the undercarriage, a slewing gear brake that acts on the slewing gear to brake a rotation of the superstructure, and a jib mounted on the superstructure as to be adjustable in luffing angle and/or in length. The mobile crane additionally contains a dolly coupling arranged on the jib and by which the jib is coupled to a mobile crane dolly during dolly travel with the superstructure in an extended position. The mobile crane further has a sensor interface for connecting a dolly coupling sensor, and a controller that is adapted to ascertain during dolly travel, in dependence on a signal received from the dolly coupling sensor, whether the jib rests on the mobile crane doll, and to activate the slewing gear brake if it does not.

A manufacturing device includes a first hinge defining a first axis of rotation and having an arm connected thereto. A parallel link mechanism includes a second hinge connected to the arm and first and second links pivotably connecting the second hinge to an attachment such that the attachment is vertically movable relative to the second hinge. A nut runner is configured to rotatably drive a fastening tool about a third axis of rotation and is connected to the attachment. A first motor is provided on the first hinge and is configured to horizontally rotate the arm about the first axis of rotation. A second motor is provided on the second hinge and is configured to horizontally rotate the parallel link mechanism about a second axis of rotation that is parallel to the first and third axes of rotation.

A lift device includes a base, a boom coupled to the base, and an actuator assembly having (i) a first end coupled to the base and (ii) an opposing second end coupled the boom. The actuator assembly includes a first actuator, a second actuator, and a coupler coupling the first actuator and the second actuator together at or proximate one of the first end or the opposing second end of the actuator assembly. The coupler is pivotally coupled to a pivot point of one of the boom or the base. The coupler pivots with the first actuator and the second actuator about the pivot point.

An adjustable length tensioning member that comprises a rope, a first connector on the rope, a second connector on the rope, and a plurality of connection points between the first connector and the second connector is disclosed. The plurality of connection points have a diameter greater than a diameter of the rope. The rope may be passed through a socket coupled to a first crane component and one of the connectors on the rope is coupled to a second crane component. One of the plurality of connection points engages a seat on the socket to tension the rope between the socket and the connection point.

A crane, in particular a mobile crane, having a closed hydraulic circuit in which a hydraulic pump is hydraulically connected to at least one hydraulic motor via a feed and a discharge, and in which the feed is hydraulically connected to the discharge via at least one bypass which bypasses the at least one hydraulic motor, wherein the at least one bypass includes a continuously adjustable valve for variably controlling the fluid flow bypassing the at least one hydraulic motor. In addition, a corresponding control device and a corresponding crane control program for actuating a closed hydraulic circuit of a crane are provided.

Hydraulic supply systems and cranes incorporating the same are disclosed. Hydraulic supply systems may include an auxiliary hydraulic circuit that includes a pump, a power source, and a plurality of plumbing elements. The hydraulic supply systems may further include a control system that controls operation of at least a portion of the plurality of plumbing elements and a control panel that is positioned remotely from the control system and is in communication with the control system, where the control panel provides selective input to the control system.

A tracked vehicle includes a pilot control module which enables the pilot to steer the tracked vehicle using an existing joystick of the tracked vehicle. The tracked vehicle also includes a dual track drive pedal which drives the tracks of the vehicle simultaneously. The joystick is used to make steering corrections when utilizing the dual track drive pedal.
