摘要： A self-propelled, dual motor, variable width riding trowel (20) for finishing a concrete surface. The riding trowel (20) comprises a frame (25) mounting a seat (70) for an operator and controls accessible by the operator for steering and controlling the trowel (20). Adjustable subframe (69) blocks mount a pair of motors (32,35), each driving a bladed rotor (37,40) for frictionally contacting the concrete surface (47) and supporting the frame (25). Displaceable gearboxes, pivotally mounted to the subframe (69), transfer rotation from each motor (32,35) to its rotor (37,40). The motors (32,35) are interlinked by an extensible driveshaft extending between the gearboxes that synchronizes the rotors (37,40). Lever arms (165,170) disposed beneath the frame (25) tilt the gearboxes and rotors (37,40) in response to the controls for steering the trowel (20). An extensible guard cage (30), mounted to the frame (25), prevents inadvertent contact between the rotors (37,40) and foreign objects. The trowel (20) may be expanded to receive finishing pans on the blades (45) of the rotors (37,40). Expansion of the trowel (20) requires displacement of several components. Each motor (32,35) and gearbox is mounted to a sliding block (85) mated to frame rails (90) which slidably couple the blocks (85) to the frame (25). The controls comprise a replaceable torque shaft having a length dependent on the distance between the axes of the rotor-gearbox assemblies.

摘要： A battery-powered electric polisher for treating concrete has the operational form of a self-propelled riding trowel. A rigid frame mounts a pair of rotors that descend into contact with the concrete surface. Hydraulic tilting circuits for polisher steering control are activated with joysticks. An electrically driven hydraulic pump powers the tilting circuits. Each rotor drives a lower, circular drive ring comprising a plurality of spokes. Drive ring spokes are nested within rigid channels defined in a lower a support plate so that the latter is removable. A plurality of radially spaced-apart abrasion devices descend from the support plate into contact with the concrete surface.

摘要： An adaptor assembly for concrete finishing trowels that enables efficient polishing of concrete surfaces, and trowels equipped with said adaptors. A large, rigid, circular adaptor disk supports a plurality of spaced-apart polishing rotors that project into contact with the concrete surface being treated. Each polishing head is rotatably secured to the adaptor disk with a spindle assembly including suitable alignment bearings. The spindle assembly secures a rigid header beneath the adaptor disk that sandwiches a resilient, annular coupler between itself and a rigid driver plate beneath the coupler. Bosses on the coupler insure spacing and enable proper flexure. The driver plate removably mounts a resilient finishing ring, that supports a plurality of radially spaced apart, downwardly projecting, diamond-equipped pucks that frictionally bear against the concrete surface for abrading and polishing.

摘要： A roller tube concrete finishing machine includes retractable vibration gangs that can be selectively immersed within wet concrete and then retracted with parallelogram linkage. Spaced-apart, drive parallel rollers are journaled between frame ends for supporting and propelling the machine upon and between parallel form rails. A front roller provide a strike-off function. The vibration gangs are deployed by a retractable, parallelogram linkage that moves them forwardly and downwardly for operation, or which retracts the vibrators inwardly and upwardly relative to the frame. When the vibrators are retracted, the are withdrawn upwardly from the concrete and retracted rearwardly towards the machine front to reduce machine dimensions. Substantial retraction of the vibrators prevents subsequent interference with the rebar below. Vibrator retraction reduces overall machine dimensions for clearance and shipping purposes, with gang vibration arrays nested upwardly and inwardly proximate the front of the machine.

摘要： A steerable, self-propelled cart for safely delivering heavy loads, such as concrete, within job sites with unlevel, irregular, or sloped terrain. A cargo bucket is tiltable over front drive wheels for transporting and dumping cargo. Hydraulic drive motors driven by a hydraulic pump propel rear wheels at a selectable speed. Steering handlebars rotate a steering column that turns the rear wheels. A throttle cable extending from the handlebars controls the throttle setting by pivoting a throttle lever mounted on the hydraulic pump. Limiting linkages extend from flanges on an anchor bracket secured to the steering column to a bridge on the throttle lever. As the steering column rotates, the limit linkages are wound partially about it, pivoting the throttle lever by pulling on the bridge, reducing pump speed. Heavy steering displacements will retract the throttle lever to reduce cart speed notwithstanding the previous speed setting chosen by the operator via the cable.

摘要： A dual rotor, manually steered riding trowel comprises powered, downwardly projecting rotors driven by reduction gear boxes that are tilted by parallel levers beneath the machine. A pair of vertical hand steering levers actuate the parallel levers to tilt the rotors. Each rotor may be swiveled in an arc parallel with the biaxial plane to produce pivoted fore and aft trowel movement. At least one rotor responds to lateral movements of one or both steering levers by tilting in an arc perpendicular to the biaxial plane, moving the trowel left or right. To emulate prior Allen trowels, lateral movements of one of the hand levers is mechanically disabled with a transformation link anchored to the frame. The transformation link may be disconnected from the frame and instead connected to the foot of the companion hand steering lever, allowing both steering levers to pivot laterally, resulting in a different steering “feel.”

摘要： A power riding trowel for finishing concrete comprising rotors turned by gearboxes driven by gearbox driveshaft's linked to the moor output by CVT gear ratio control. The motor output shaft drives a first jackshaft driven at a higher speed than the motor RPM. A CVT pulley assembly comprising first and second CVT pulleys and a CVT belt entrained between them has a first CVT pulley driven by the first jackshaft. A second jackshaft splined to the second CVT pulley drives the gearbox driveshaft at a speed lower than said second jackshaft to operate the rotor means at a proper speed and torque.

摘要： An electrically powered, self-propelled cart for safely delivering heavy loads, such as concrete, within job sites with unlevel, irregular, or sloped terrain. A cargo bucket is tiltable over front drive wheels for transporting and dumping cargo. Electric drive motors associated with a transaxle propel wheels at a selectable speed in response to an electric control module. A steering column rotates in response to manually operated handle bars and activates a sensor to generate signals delivered to the control module for throttle adjustments. The sensor may be a linear potentiometer, a rotary differential transformer or a rotary encoder or shaft encoder measuring angular displacement. Extreme steering displacements will electrically reduce cart speed notwithstanding the previous speed setting chosen by the operator through the steering column.
