A self-trailering grain bagging machine on four wheels for storing grains and seeds inside a silo bag. The machine has a grain receiving hopper within which a compression auger encased in an auger tube. The auger is driven by mechanical means powered from a tractor's power take-off. The machine is mounted on a frame fitted with paired crossmembers at its left and right hand sides. Each crossmember is mounted upon a pair of wheel supports. The wheel supports are capable of gyrating relative to the crossmembers. The wheel supports carry one wheel that wheel rotates along with said wheel support. A work tongue is attached to the front side of the frame. The work tongue pivots relative to a horizontal axis. A transport tongue is attached to one crossmember wherein the wheels remain aligned in the direction intended for work and when turning said wheel supports by 90 degrees.

Disclosed is a system for the storage and traction of a cable, in particular a synthetic cable fitted to an offshore crane. The storage/traction system includes a frame that carries in particular a storage device including a support carrying a storage reel through an assembly defining an axis of rotation. Between the storage reel and the support, the assembly includes of a single slewing ring including two rings that are free to rotate with respect to each other: —a fixed ring that is fastened to the support; and —a moving ring that is, on the one hand, fastened to the storage reel and, on the other hand, rotated by a motorization.

A manoeuvring arrangement for a working equipment, includes a manoeuvring unit and control unit. The manoeuvring arrangement is configured to initiate a selection state in response of a first interaction by an operator with a first selection member. A control unit, when in a selection state, controls a second display section to display a navigation view including a list of a group of a plurality of predefined operation modes. A timer module monitors the time period since the last interaction by the operator with the first selection member and generates an exit selection state signal in response of the monitored time period being larger than a predefined selection time period. The manoeuvring arrangement leaves the operation mode selection state if an exit selection state signal has been generated and initiates the operation mode by applying the operation mode with a marking in the displayed list on the second display section.

A vehicle may be configured with an adjustable horizontal planar platform for receiving a load, such as a boom arm of a crane and transporting the load to a new location. In some cases, the platform is configured to swivel and tilt in order to maintain an alignment with a second vehicle during transport of a load.

A work vehicle includes: an operation tool that is operated by an operator; and a controller that determines a target flow rate for hydraulic oil fed to a hydraulic device on a basis of the amount of operation of the operation tool. The controller calculates a bleed-off target flow rate on a basis of the flow rate of hydraulic oil fed from a hydraulic oil pump and the target flow rate for hydraulic oil fed to the hydraulic device, calculates a bleed-off throttle differential pressure on a basis of a pressure of hydraulic oil fed from the hydraulic oil pump and a pressure of hydraulic oil in a hydraulic oil tank, calculates a bleed-off target opening area on a basis of the bleed-off target flow rate and the bleed-off throttle differential pressure, and controls a hydraulic oil control valve such that the bleed-off target opening area is achieved.

A crane, in particular a pick and carry crane, may have a front chassis with front wheels and a back chassis with back wheels, the front chassis being articulated relative to the back chassis so that the crane can travel whilst carrying a load suspended from a boom. The back and front wheels have independent suspensions which are capable of connection to one another so that movement of a left wheel influences movement of a right wheel, thereby improving the handing of the crane, particularly over rough terrain.

A hydraulic system for controlling bleed down and retraction of a boom within a safety envelope includes a backup battery power supply, and at least a first boom lift hydraulic cylinder configured to raise and lower the boom. The first boom lift hydraulic cylinder includes a solenoid bleed valve electrically connected to the backup battery power supply. The hydraulic system also includes an input device controllable by an operator of the boom. The input device may, for instance, be used by the operator to initiate bleed down and retraction of the boom from an elevated position. To accommodate independent failsafe features of the system, the input device is configured to selectively actuate the solenoid bleed valve using electrical power supplied from the backup battery power supply.

Provides is a crane in which the manipulation according to an operator's intention is more easily performed. The crane includes a manipulating member capable of performing at least one of an accelerator manipulation for increasing or decreasing a rotational speed of an engine and a turning manipulation of a turning body. A predetermined operation is stopped in a case where an operator is not touching the manipulating member and the predetermined operation (turning operation, traveling operation, or the like) of the crane is performed.

A telescopic side arm for a refuse vehicle has an inner and outer boom. A mounting assembly secures the outer boom with a refuse vehicle. A plurality of bearing pads is positioned between the inner and outer booms to provide smooth movement between the inner and outer booms. A plurality of shims is associated with the bearing pads to assure a tight fit between the inner and outer booms.

The present invention addresses the problem of providing: a crane control method whereby, during automatic transportation of a load along a preset transport route using a crane, it is possible to reliably transport the load along the route; and a crane that can be controlled by the crane control method. A control device (32) calculates target speed signals (VU), (VW), (VR) for designating the target hoisting speed and the target rotational speed of a boom (9) and the target winding/unwinding speed of main wire rope (14) or sub wire rope (16), calculates the maximum speeds (VUmax), (VWmax), (VRmax) of the hoisting and rotation of the boom (9) and winding/unwinding of the main wire rope (14) or the sub wire rope (16), and, if a target speed exceeds the corresponding maximum speed, controls the crane (1) by multiplying the target speed signal (VU), (VW), (VR) by a coefficient and restricting the target speed signal (VU), (VW), (VR) to be less than the corresponding maximum speed.
