As the hose lifting device lifts the hose upward, the hose support element is automatically adjusted from the non-support state to the support state to support the lifted hose.

Abstract: A screeding machine for screeding an uncured concrete surface includes a screed head assembly movable over the concrete surface via the screeding machine. A pair of elevation sensors disposed at opposite ends of the screed head assembly sense an elevation of the respective end of the screed head assembly. An angle sensor disposed at the screed head assembly senses a pitch angle and/or a roll angle of the screed head assembly. A gyroscope sensor disposed at the screed head assembly senses rotational velocity of the screed head assembly about a lateral axis and/or a longitudinal axis of the screed head assembly. A control uses gyroscope sensor data and angle sensor data to determine pitch angle and/or roll angle of the screed head assembly. The control controls the screed head assembly based on the signals from one or both of the elevation sensors and the determined pitch and/or roll angles.

Abstract: A protective shield device is disposed at the joint between connected concrete hoses to protect the joint connecting one concrete hose to another from accidentally catching on an obstruction on the surface over which the concrete hose joint is moved during operation and disconnecting the two concrete hoses. The protective shield device is formed by two housing portions that are hinged on one side and connected by one or more retaining elements to surround and encapsulate the concrete hose joint. The closed protective shield device has a larger central portion to accommodate the joint structure, and narrower end portions to provide no protruding structure that will catch any underlying obstructions that could cause the enclosed joint latch to be exposed.

The pair of grasping arms move from their opened state toward their closed state to engage and grasp the concrete supply hose. As the grasping device raises the grasped hose upward, the support arms pivot from their opened state toward their closed state to support the grasped and raised hose.

Abstract: A protective shield device is mounted on the joint between connected concrete hoses to protect the joint connecting one concrete hose to another from accidentally catching on an obstruction on the surface over which the concrete hose joint is moved during operation and disconnecting the two concrete hoses. The protective shield device is formed by two hollow shells that are hinged on one side and connected by friction closure members to surround and encapsulate the concrete hose joint. The assembled protective shield device is preferably in the shape of an ovoid with a larger central portion to accommodate the joint structure, and narrower end portions to provide no protruding structure that will catch any underlying obstructions that could cause the enclosed joint latch to be exposed. The protective shield device can be opened by forcing the two shell members apart, or by using a mechanically disengagable latch.

Abstract: A method for screeding of an uncured concrete surface includes providing a screeding machine and a control. The uncured concrete surface is screeded and the control processes data captured by the sensors while the screeding machine is screeding the uncured concrete surface. While the screeding machine is screeding the uncured concrete surface, and responsive to data processing by the control of data captured by the sensors while the screeding machine is screeding the uncured concrete surface, the control estimates a flatness or levelness or quality of the surface of the concrete surface being screeded. The control may generate an output indicative of the estimated flatness or levelness or quality of the surface, and/or a display may display information associated with the estimated flatness or levelness or quality of the surface.
