    摘要： A screeding system for use with a screeding machine during screeding of an uncured concrete surface includes a base unit, a support arm extending from the base unit, and an elevation frame disposed at an outer end of the support arm. The elevation frame comprises elevation actuators at opposite ends thereof. A screed head includes a support frame that is pivotally mounted at lower ends of the elevation actuators. The support frame supports an auger, a plow and a vibrating member. A pair of actuators extend and retract to rotate the support frame about an axis parallel to an auger axis. The actuators adjust the support frame and screed head between a screeding orientation and a cleaning orientation. Responsive to a user input, the actuators rotate the support frame to the cleaning orientation, whereby the support frame rotates at least 60 degrees about the axis.

    摘要： Methods of and apparatus for controlling relative telescoping extension or retraction of multiple telescoping assemblies is provided. The telescoping assemblies connect the main frame of a slipform paver to a side member of the slipform paver. Each telescoping assembly has a telescopic lock associated with the telescoping assembly. A common telescoping force is applied across the telescoping assemblies to widen or narrow the frame width of the slipform paver. Extension of the telescoping assemblies is monitored, and activation of the telescopic locks is controlled so as to determine which of the telescoping assemblies is allowed to telescope under application of the common telescoping force.

    摘要： A screeding machine for screeding an uncured concrete surface includes a wheeled unit having a plurality of wheels for moving the wheeled unit over a support surface. A screed head assembly includes a grade setting device and a vibrating member and is movable over the concrete area via the wheeled unit. The grade setting device includes an at least partially cylindrical concrete engaging surface, such as a roller that is rotatably mounted at the screed head assembly and rotatably driven about its longitudinal axis. The screed head assembly may include a wiper element disposed along the roller and configured to wipe or remove excess concrete from the roller during rotation of the roller about its longitudinal axis. The grade setting device or roller plow assembly may be provided as an aftermarket kit for attachment at a screed head assembly of a screeding machine.

    摘要翻译： 用于熨平未固化的混凝土表面的刮板机包括具有多个轮子的轮式单元，用于将轮式单元移动到支撑表面上。 刮板头组件包括坡度设置装置和振动构件，并且可以经由轮式单元在混凝土区域上移动。 坡度设置装置包括至少部分圆柱形的混凝土接合表面，例如可旋转地安装在熨平板头组件上并围绕其纵向轴线可旋转地驱动的辊。 熨平头组件可以包括沿着辊设置的擦拭器元件，并且构造成在辊围绕其纵向轴线旋转期间从辊中擦拭或去除多余的混凝土。 坡度设置装置或辊犁组件可以作为售后工具包提供，用于在熨平机的熨平板头部组件上附接。
