  • Publication number: 20170253085
    Abstract: An aircraft tire having improved wear properties is provided. The tire includes a belt reinforcement structure (128) that provides a flatter crown and reduces localized tensions. The belt reinforcement structure includes at least two hybrid belt plies (130,132) having free ends that are positioned radially inward of at least one non-hybrid belt ply (134,136). The hybrid belt plies allow for reductions in the overall mass of the tire and improved thermal properties while still meeting requirements for burst pressure and size for aircraft tires.

  • Patent number: 6247887
    Abstract: The present invention discloses either an apparatus that is adapted for selective mounting to and demounting from a pallet jack for use therewith or a transport vehicle having an apparatus permanently mounted thereto, which can effectively and efficiently transport articles or stacks of objects, such as boxes, furniture, trays, or the like from one location to another. The apparatus comprises a housing and an article engaging and lifting member, which includes a base and a back support member for supporting the article or stacks of objects. The article engaging and lifting member is pivotally mounted to the housing, preferably adjacent the bottom of the back support member. In one embodiment, the apparatus further includes a first clamp member for maintaining the article adjacent the back support member.

  • Patent number: 5462136
    Abstract: The present invention features a method and an apparatus for preventing lift chains from becoming slack in a lift truck with a "man-up" feature installed. Lift trucks are generally those vehicles that feature hydraulically controlled lift masts with a chain supported fork carriage. Operators of these lift vehicles with the remote lift and lower feature are generally lifted and lowered by these masts, known in the trade as a "man-up" condition. It is quite desirable to prevent a slack chain condition in the man-up mast position. The invention features a pressure transducer for monitoring a drop in hydraulic fluid pressure established by the flow control valve that regulates the lowering speed of the mast during the remote mode, i.e., when the fork carriage is being lowered by the operator in the platform attached to the fork carriage.
