  • Patent number: 11859371
    Abstract: A wear part, a bucket, bucket system and a method for attaching the wear part to the bucket are provided. The wear part includes a forward edge for intruding into a material to be handled by the bucket, and an engagement portion for engaging with an engagement edge of the bucket. The engagement portion has a concave cross section. A lever element extends from a side of the engagement portion in a direction backwards from the forward edge, and a fastening unit is arranged in a distal end of the lever element. The bucket has a plate hole arranged behind a bucket threshold in relation to an engagement edge for receiving a fastening element for fastening the wear part to the bucket.

  • Patent number: 8281671
    Abstract: A load measuring device for measuring a load acting on an elastically deformable member, has a distance sensor for measuring a length change in response to a deformation of the deformable member under a load. The sensor has a sensing element and a reference element arranged such that a portion of the elastically deformable member is interposed between the sensing element and the reference element. For paper manufacturing or finishing, two members between which the load is measured are cooperating rolls, at least one of which is provided with an elastic cover. One of the rolls includes the sensing element and the other roll includes the reference element. Alternatively, the two members are a roll and a cooperating belt, one having an elastic cover. Also, the sensing element and the reference element may be formed in one and the same member.

  • Patent number: 7549370
    Abstract: A regulating unit for accomplishing a linear movement includes a cylindrical frame part (1) having a cylinder part (11) and cylinder head (12), which define a piston space (131, 132), and a piston unit (2) to be moved by a pressurized medium in the piston space. The height of a first space (131), in which a piston part (22) is moveable, is bigger than the height of a piston part, the cross section area is bigger than a cross section area of a piston rod. A cross section area of a second space (132) is smaller that the cross section area of the piston part. Pressurized medium may be fed into a cavity space (15), which is between the facing surfaces of the piston part and the piston space, for moving the piston unit towards the cylinder head (12) or vice versa.
