    摘要： 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.

    摘要： A handle assembly for a power tool is disclosed. The handle assembly has a handle (84), a metal strip (82) for releasably mounting the handle assembly to the housing of a power tool, and a fastening mechanism (80, 100, 104) for tightening and loosening the metal strip on the housing of the power tool. Vibration dampers (124, 126) are located between the handle and the fastening mechanism to damp vibrations transmitted from the fastening mechanism to the handle. Limited rotation of the handle relative to the metal strip is possibly, but rotation beyond predetermined limits causes the fastening mechanism to tighten and/or loosen the metal strip on the housing.

    摘要： An example wheel restraint includes a wheel chock that is manually movable between a retracted or release position clear of a wheel of a vehicle at a loading dock and an operative position to block the path of the wheel. In the release position, the chock can be manually moved freely along a track that is mounted to a driveway of the dock. When the chock is manually moved from its release position to its operative position, a locking feature automatically restricts the movement of the chock relative to the track. When the chock is manually moved back to its release position, the locking feature automatically disengages. Although the wheel chock is connected to a track, much of the force exerted by the wheel against the chock can be transmitted directly from the chock to the driveway.

    摘要翻译： 示例性轮毂限制器包括可在手动移动的轮轴承座之间，在缩回位置或释放位置之间，在装载基座处的车辆的车轮和用于阻挡车轮的路径的操作位置。 在释放位置，轴承座可以沿着安装到码头的车道的轨道自由地移动。 当将轴承座从其释放位置手动移动到其操作位置时，锁定特征自动地限制轴承座相对于履带的移动。 当轴承座手动移回到其释放位置时，锁定功能会自动脱开。 虽然车轮轴承座连接到轨道上，但车轮抵靠轴承座施加的大部分力量可以直接从轴承座传递到车道。

    摘要： A wheel restraint for restraining a vehicle at a loading dock includes a wheel chock suspended from a tether. The tether hangs from an overhead beam such that the wheel chock can be swung down and underneath the vehicle and placed directly in front of a wheel of the vehicle. A pin can be used to help hold the chock to an anchor that is fastened to a driveway of the loading dock. The orientation of the pin and the anchor holes in which the pin can be selectively inserted prevents the chock from tipping back and makes the restraint more tolerant of dirt, ice and other contaminants. In some examples, an offset between the beam and the wheel results in the tether urging the chock toward the anchor.
