摘要： Systems and methods of controlling a vibrating screed. One vibrating screed includes a screed member, a motor configured to vibrate the screed member, and a speed sensor configured to output speed signals indicative of a motor speed. A controller is connected to the speed sensor and the motor. The controller is configured to drive the motor according to a speed command, receive the speed signals from the speed sensor, determine whether the motor speed is less than or equal to a speed threshold, and terminate, in response to the motor speed being less than or equal to the speed threshold, operation of the motor.

摘要： A tool for the mechanical treatment of a concrete floor, such as for power trowel floating and finishing with blades, for conducting the treatment with a hand-operated, walk-behind or ride-on actuator, such as e.g. with a concrete power trowel, a floor treating apparatus, or the like. The actuator includes one or more operating heads, which include several, such as four, attachment arms perpendicular to each other, for treating a concrete floor with tools coupled in a removable manner into the engagement with each attachment arm. A tool is intended for use in engagement with a trowel floating blade coupled to an attachment arm of the actuator's operating head, whereby the tool with a substantially flat and elongated body includes first and second elements for its coupling and locking on a quick coupling principle for im-movable engagement with the trowel floating blade.

摘要： A device provides for an efficient, fast, and less labor-intensive way of laying dovetailed interlocking flooring material which have interlocking tabs to connect adjoining flooring material. The device comprises of a chassis offering structural support to which all other elements are connected to either directly or indirectly. The chassis has an upper portion which accepts additional weight and an undercarriage portion which is configured to connect to one or more front wheels and back wheels. The front wheels are configured to put pressure along each side of the interlocking tabs, while the one or more back wheels are configured to press on the interlocking tabs, and wherein the combined weight of the device interlocks the interlocking tabs in the flooring material.
