摘要： A wheel restraint includes a wheel chock that is manually movable between a retracted 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 retracted 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 retracted 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 retracted position, the locking feature automatically disengages. Although the wheel chock is connected to a track, most of the force exerted by the wheel against the chock is transmitted directly from the chock to the driveway.
摘要翻译：轮限制器包括一个轮轴承座，该车轮轴承座可手动地在装载基座处的车辆的车轮的缩回位置和阻止车轮路径的操作位置之间移动。在缩回位置，轴承座可以沿着安装到码头的车道的轨道自由地移动。当将轴承座从其缩回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缩回位置时，锁定功能会自动脱开。虽然车轮轴承座连接到轨道，但车轮抵靠轴承座施加的大部分力量直接从轴承座传递到车道。

摘要： Example dock levelers installed at a vehicle loading dock include pivotal or otherwise vertically adjustable deck plates with special coatings on the deck's upper surface. In some examples, the coating improves traction and addresses various thermal issues, such as condensation and thermal strain between a polymeric coating and a steel deck plate. In some examples, when indoor and outdoor air create a temperature differential across opposite faces of the deck, the coating is designed such that a median temperature of the temperature differential occurs near an interface where the coating bonds to the steel plate's upper surface. In some examples, the coating includes particles of different sizes and colors embedded within and covered by a polymeric base material. As traffic abrades the coating, the different colored particles become exposed at different levels of wear, thereby providing a visual signal indicating when the coating needs to be touched up or replaced.

摘要： A hand held motor driven electrically powered tool, in particular a rotary hammer, comprising a spindle (40) for rotatingly driving a tool or bit (68), a spindle rotary drive train (14, 5, 10) for rotatingly driving the spindle (40) and an arrangement for detecting blocking events (16, 17). Blocking events occur when the tool or bit of the tool become rotationally fixed in the material being bored in which case the rotary drive on the spindle from the motor causes the tool housing to rotate in a user's grip. According to a first aspect of the invention an overload clutch (14) is provided in the spindle rotary drive train for transmitting rotary drive to the spindle below a predetermined torque and slipping above the predetermined torque arranged such that the overload clutch cuts off rotary drive to the spindle, for example by reducing the predetermined torque at which the overload clutch (14) slips when a blocking event is detected so as to cut off rotary drive to the spindle in response to a blocking event being detected. According to a second aspect of the invention there is provided a mode change mechanism (45, 47, 49, 43) for selectively disengaging a clutch (10, 7) so as to cut off the rotary drive to the spindle (40) and the clutch is disengaged when a blocking event is detected so as to cut off rotary drive to the spindle in response to a blocking event being detected.
摘要翻译：一种手持马达驱动的电动工具，特别是旋转锤，包括用于旋转地驱动工具或钻头（68）的主轴（40），用于旋转地驱动主轴的主轴旋转传动系（14,5,10） 40）和用于检测阻塞事件（16,17）的装置。当工具的工具或钻头被旋转地固定在钻孔材料中时，发生堵塞事件，在这种情况下，来自马达的主轴上的旋转驱动器使得工具壳体在使用者的把手中旋转。根据本发明的第一方面，一种过载离合器（14）设置在主轴旋转传动系中，用于将转动驱动传递到预定转矩以下的预定转矩，并且在预定扭矩以上滑动，使得过载离合器将旋转驱动器切断主轴，例如通过减小当检测到阻塞事件时过载离合器（14）滑动的预定扭矩，以便响应于检测到阻塞事件而切断到主轴的旋转驱动。根据本发明的第二方面，提供了一种用于选择性地分离离合器（10,7）以便切断到主轴（40）的旋转驱动器的模式改变机构（45,47,49,43），并且当检测到阻塞事件时，离合器分离，以便响应于检测到阻塞事件而切断到主轴的旋转驱动。
