  • Publication number: 20220250879
    Abstract: Provided is a work vehicle that can be transported by being loaded onto a trailer without having the outriggers removed. The work vehicle (rough terrain crane) is transported by being loaded onto a low bed trailer including a low bed and a high portion (first high bed, second high bed) higher than the low bed in at least one of the front and the rear of the low bed, and includes: outrigger units (front outrigger unit, rear outrigger unit) that are mounted to the front and rear of a vehicle body; and a lift unit that lifts and lowers the outrigger units (front outrigger unit, rear outrigger unit with respect to the vehicle body.

  • Publication number: 20220228894
    Abstract: There are provided piezoelectric element, case having conductivity, first acoustic matching layer bonded on case, and second acoustic matching layer stacked on and bonded to first acoustic matching layer. A joining part between first acoustic matching layer and second acoustic matching layer is located inside an outer periphery of a joining surface of first acoustic matching layer that is joined to second acoustic matching layer. This configuration can prevent indirect wave generated in first acoustic matching layer from propagating to second acoustic matching layer, and can therefore reduce reverberation of an ultrasonic wave.

  • Patent number: 10246314
    Abstract: A boom-extending wire locking structure has a wire locking tool, provided at a base end side of a first boom member and/or a base end side of a third boom member, that locks an extending wire by winding a lock part of each wire member. The wire locking tool includes: a pair of fixing pieces provided on both sides in an orthogonal direction orthogonal to a boom-extending direction and fixed to the first boom member and/or the third boom member; and wire locking parts, provided between the pair of fixing pieces, including arch-shaped grooves for winding the respective lock parts of the wire members. The wire locking parts are arranged in a central axis direction of the arc shape between the pair of fixing pieces. Central axes of the wire locking parts are arranged at different positions in the orthogonal direction from respective adjacent wire locking parts.
