  • Patent number: 9056356
    Abstract: A device for machining workpieces, in which a surface plate (1) that can be driven about a rotational axis (W) can be moved in a linear fashion along the rotational axis (W) and the rotational axis (W) is constructed as a hollow axis (H), on the outside diameter of which the surface plate is rotatably mounted, and in which two cross slides (2, 3) which can be displaced radially to the outside and inside perpendicular to the rotational axis (W) are provided on the surface plate (1), and in which the surface plate (1) can be driven by a first drive and the cross slides (2, 3) can be driven by a common second drive.

  • Patent number: 6814188
    Abstract: The invention relates to a scissors-like lifting device having a pair of scissors that are arranged between a carrier or support unit and a base unit. Each pair of scissors is provided with two arms which can be pivoted about corresponding axles. The scissors-like lifting device is provided with a lifting truck that can be moved by means of a drive in order to open and close the scissors. The inventive configuration efficiently controls the lifting movement. The band-like traction mechanism can be wound-up on the drum by means of the drive in order to pull the lifting truck towards the scissors axle so that the scissors are opened. The band-like traction device can be unwound from the drum so that the truck is moved away from the scissors axle by the force of gravity on the support and arms thereby closing the scissors.

  • Patent number: 6705238
    Abstract: The disclosure relates to a scissors lifting device having a pair of scissors positioned between a carrier unit and a base unit. The scissors have inner arms and outer arms which can pivot in relation to each other about a scissors axle. The lifting device further includes a lifting truck that can be moved back and forth by means of a drive in order to open and close the scissors. According to the invention, a drive shaft that is oriented parallel to the scissors axle is coupled to the drive and enables at least one traction mechanism that is arranged around the drive shaft and is coupled to the lifting truck to be moved in both directions of rotation. This results in a construction having a reliable drive.
