  • Patent number: 10286536
    Abstract: A tool holder system with first and second spindles, a locking ring slideably mounted on the first spindle, a first biasing mechanism biasing the locking ring towards an indentation position where the locking ring surrounds an indentation on the first spindle, and a moveable locking element mounted on the second spindle, the locking element being engageable to the indentation. The first spindle can be unlocked from the second spindle by sliding the locking ring away from the indentation position against the biasing force of the biasing mechanism and towards the second spindle. Such action moves the locking element to disengage from the indentation.

  • Patent number: 9694996
    Abstract: An example dock leveler with safety supports including a deck having a deck plate, a plurality of support beams, a first side plate and a second side plate. The deck plate has an outer perimeter defined by a front edge, a rear edge, a first lateral edge and a second lateral edge. A first deck obstruction extends underneath the deck plate and is selectively configurable to at least one of a blocking position or a stored position. The first deck obstruction is elongate in a lateral direction and the first deck obstruction has a protruding end. The first side plate is closer to the protruding end when the first deck obstruction is in the stored position than when the first deck obstruction is in the blocking position. The first deck obstruction extends laterally beyond the deck width when the deck obstruction is in the blocking position. The first deck obstruction includes a pulling enhancement at the protruding end.
