A slewing ring grease assembly for providing grease to internal gear teeth of a slewing ring. The slewing ring grease assembly includes a bulkhead fitting having a flange and a shaft, the shaft extends through a hole in the bulkhead attached to the slewing ring such that the shaft extends over the internal gear teeth of the slewing ring. The bulkhead fitting flange is secured to the bulkhead on a side opposite the internal gear teeth of the slewing ring. A passage through the bulkhead fitting is provided which is capable of delivering grease through the bulkhead fitting and onto the internal gear teeth of the slewing ring. The grease assembly may include a wall fitting extending through a wall of housing supporting the bulkhead and a connecting tube capable of delivering grease from the wall fitting to the passage of the bulkhead fitting.

A wheeled hose moving device that is movable over a support surface and that is operable to grasp, lift and move a concrete supply hose at the support surface. The device includes a wheeled support including a hose grasping device and at least one hose support element. The hose grasping device includes a pair of grasping arms configured to grasp and release a concrete supply hose. The hose grasping device is vertically movable between a raised position and a lowered position. The hose support element includes a pair of support arms that pivot relative to one another. The pair of grasping arms move from their opened state toward their closed state to engage and grasp the concrete supply hose. As the grasping device raises the grasped hose upward, the support arms pivot from their opened state toward their closed state to support the grasped and raised hose.

A system (100) comprising a boom tip attachment bracket (108) on a boom (102) of a working machine, the boom (102) having an actuator (104) attached thereto and one or more flexible lines (106), a processing head attachment bracket (110) for rigidly attaching a processing head (112) to the boom (102) of the working machine, the processing head attachment bracket (110) having a line connection point (114) for connecting the one or more flexible lines (106), and an internal line passage (116) for passage of the one or more flexible lines (106) from the boom (102) to the line connection point (114). The boom tip attachment bracket comprises (108) a first rigid frame (118) having at least two plates (120a, 120b) spaced from each other by a first spacing distance (122) so as to comprise at least a portion of the internal line passage (116), and a pair of first coupling points (124a, 124b) opposed across the first spacing distance (122), for rotatably coupling the rigid frame (118) to the processing head (112) along a first rotation axis (126a). The processing head attachment bracket comprises a second rigid frame (128) having at least two plates (130a, 130b) spaced from each other by a second spacing distance (132) so as to comprise at least a portion of the internal line passage (116); and a pair of second coupling points (134a, 134b), opposed across the second spacing distance (132), and rotatably coupled with the pair of first coupling points (124a, 124b) along the first rotation axis (126a). The processing head attachment bracket (110) is coupled to the actuator (104) by a torque assembly (136) for translating actuation of the actuator (104) into a rotation of the processing head attachment bracket (110) about the first rotation axis (126a), and the internal line passage (116) passes through at least the first rotation axis (126a).

A hydraulic control circuit operable to selectively hydraulically link first and second hydraulic actuators and to bypass that hydraulic link.

A tire gripping device includes a chuck mechanism having a pair of chuck portions adjacent in a width direction of a tire and contact members disposed on each of the chuck portions in a circumferential manner. The contact members are able to be brought into contact with an open end portion of a bead portion of the tire. The contact members are able to enter a state of allowing relative movement with a contact surface of an open end portion in a first contact stage and enter a state of non-relative movement with the contact surface in a second contact stage subsequent to the first contact stage. The tire gripping device further includes a first driving mechanism for moving the contact members in a radial direction of the tire and a second driving mechanism for moving the pair of chuck portions in the width direction of the tire.

A quick coupling system for changing attachments on a construction machine, which contains a quick coupler arranged on a support so as to be rotatable about a rotary axis by means of a rotary drive and/or pivotable about a swivelling axis by means of a swivel drive for coupling a tool or an attachment part. A gripping tong arrangement, which can be actuated by means of a gripper drive, is arranged on the quick coupler and has a plurality of gripper arms which can be moved against each another, and exchangeable gripper elements are arranged on the gripper arms.

An apparatus and method for handling portable traffic delineators includes a lifting arm assembly and a gripper assembly arranged to move portable traffic delineators between a cargo platform on a vehicle and a road surface. The gripper assembly has guide rails that define a V-shaped receiving structure with rollers to guide and center the portable traffic delineators within the V-shaped receiving structure. The gripper assembly also has suction cups arranged to pivot into and out of the V-shaped receiving structure for applying a suction force to the outer surface of the portable traffic delineators received in the V-shaped receiving structure. A programmable controller is used to perform a sequence of movements of the lifting arm assembly and the gripper assembly to either retrieve portable traffic delineators from a roadway or place portable traffic delineators on the roadway when the portable traffic delineators are detected within the V-shaped receiving structure.
