  • Patent number: 6129195
    Abstract: A ball transfer deck facilitates movement of heavy loads across the deck over an array of ball transfer units while reducing attendant operating noise. An annular elastomeric sleeve isolates the upper flange of each individual ball transfer unit from direct contact with the deck, thereby reducing noise generated by the contact between the ball transfer unit and deck. An associated pin stop mechanism is also installed in the ball transfer deck and can be selectively engaged to prevent the movement of a particular load across the deck. To decrease the probability of damage to the deck and increase the stability and strength of the pin stop mechanism, the preferred pin stop mechanism includes a wide upper flange that allows the pin stop mechanism to be easily attached to an upper surface to the deck.
