  • Patent number: 11873616
    Abstract: 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.

  • Patent number: 11633770
    Abstract: The present disclosure provides a method for air bending a plate of material such as steel which is characterised by having two bending steps, wherein the bending punch in the second bending step has a smaller radius and/or the die width used in the second bending step is smaller than the die width used in the first bending step. The method of the disclosure can achieve a significant improvement in the bendability of materials, particularly high strength steels. The disclosure also provides new bending apparatus that are specifically adapted to carrying out the method of the disclosure, including a nested double die having a second narrower die residing below and within the first die, and an adjustable die having a height adjustment means (either in the support, bending punch or both) capable of accommodating movement of the material during the adjustment to form the second die width.

  • Patent number: 11535909
    Abstract: A steel sheet product and a method for manufacturing the steel sheet product are described, the method includes the steps: providing at least two steel sheets extending in a longitudinal direction (A), cleaning longitudinal edges of the steel sheets by removing any surface oxide layers therefrom, joining the steel sheets along the cleaned longitudinal edges using butt welding without filler material to form a weld, wherein inert gas protection is applied on both a top side and a root side of the weld during welding, thereby obtaining a welded steel sheet product, removal of excess material from the weld, and hardening of the welded steel sheet product by means of heat treatment and subsequent quenching.

  • Patent number: 11440454
    Abstract: The present invention is in the form of a body (111) adapted to be fitted to a truck having at least two axles. The body is capable of tipping once fitted to the truck. The body comprises two side surfaces (13) interconnected by a longitudinal surface (21) to keep the side surfaces in spaced apart relation. The longitudinal surface and the side surface define a cavity (30) for receiving a payload. The longitudinal surface is configured such that the payload is self-centering as the body is loaded, such that in operation the distribution of load on each of the at least two axles remain substantially the same between a first payload having a first volume and a second payload having a second volume, neither payload resulting in the gross vehicle weight limit being exceeded.
