A method for slowing transfer of a heavy work machine on a sloping base using a transportation device equipped with wheels, the work machine including a body, a crawler chassis fitted beneath the body, a set of booms having at least one operating cylinder, a first end and a second end, said set of booms being pivoted at the first end to the work machine and a selected auxiliary device is pivoted at the second end, and a brake surface connected to the auxiliary device, in which method includes the steps of transferring the work machine by supporting the work machine on the crawler chassis at least partly on top of the transportation device, towing the work machine using a transfer vehicle with the aid of the transportation device, using said operating cylinder of the set of booms to press the brake surface against the sloping base to create friction to slow transfer speed of the transportation device on the sloping base, and adjusting pressing of the brake surface taking place through the auxiliary device using the operating cylinder or one set of booms. An arrangement in connection with a heavy work machine for transferring the work machine on a sloping base is also described.

The system extracts water from lunar regolith and includes a regolith intake having a digging bucket that collects lunar regolith soil and a gravel separator that separates and discharges gravel and passes a mixture of ice-regolith powder having ice grains that are about 10-100 microns along the conveyor. A pneumatic separator receives the ice-regolith powder and pneumatically splits the ice-regolith powder into streams of different sized lithic fragments and ice particles per the ratio of inertial force and aerodynamic drag force of the lithic fragments and ice particles. Each split stream may include a magnetic separator that separates further the magnetic and paramagnetic lithic fragments from ice particles to discharge up to 80 percent of lithic fragments to slag.

Described is a bucket for an earth-working or materials-handling machine, having a top portion comprising a web section, a first and a second bucket side wall and a bucket floor extending from a front cutting edge of the bucket up to the top portion. The front cutting edge, the first and second side walls and the top portion form an opening of the bucket, seen from a front view of the bucket. The bucket has a first inner reinforcement beam element provided on an inside of the bucket adjacent the opening, connecting the first side wall to the web section and extending in a width direction (w) of the bucket from the first side wall towards the second side wall, wherein the first inner reinforcement beam element and the web section, as seen in a sectional plane taken perpendicularly to the width direction (w), form a first perimeter profile enclosing an area. The bucket further has a second inner reinforcement beam element provided on an inside of the bucket adjacent the opening, connecting the second side wall to the web section and extending in the width direction (w) of the bucket from the second side wall towards the first side wall, wherein the second inner reinforcement beam element and the web section, as seen in a sectional plane taken perpendicularly to the width direction (w), form a second perimeter profile enclosing an area. The first and the second inner reinforcement beam elements extend in the width direction (w) such that they abut each other at a region between the first and the second side walls, and the first and the second inner reinforcement beam elements further being formed such that a height of the first and second perimeter profile, respectively, decreases towards the region.

Embodiments of the invention relate generally to excavating equipment and, more particularly, to a damping element for excavator shovel buckets that improves the protection of its components.

The present invention relates generally to a dirt screening bucket attachment device for use with an existing bucket of a skid steer, or other similar type of earth-moving machinery. More specifically, the device can be readily attached/detached to the existing bucket of the skid steer to allow a user to quickly and efficiently screen dirt, topsoil and other materials for rocks, roots and other unwanted debris by moving and articulating the bucket of the skid steer with the attachment attached thereto and in an engaged position. In addition, the attachment device may be easily articulated from a position that covers said bucket to a position above said bucket (i.e., thereby leaving the bucket opening exposed) via a hydraulic system that allows a user to utilize the full functionality of the bucket without interference from the bucket attachment device.

An excavating system for use in ground-engaging applications. The excavating system may include a wear member having a top leg, a bottom leg, and a bearing face connecting the legs. The excavating system may also include a lip, which may include a top inset surface. The top inset surface may have an upper bearing surface shaped to bear against an inner surface of the top leg of the shroud. The top inset surface may also have a forward bearing surface extending between the upper bearing surface and a lower surface formed on the downwardly facing surface. The forward bearing surface may face upwardly and forwardly at a non-vertical angle.
