Control Apparatus for Soil Compacting Apparatus, with Handlebar and Rotational Speed Lever
A control apparatus for a soil compacting apparatus which can be driven by a drive motor is provided. The control apparatus includes a running-direction operating element, which is pivotable about a first axis, for predetermining a running direction of the soil compacting apparatus by an operator, and further includes a rotational-speed operating element, which is pivotable about a second axis, for setting a rotational speed of the drive motor. The first axis and the second axis are congruent and form a common pivot axis.
Control Apparatus for Soil Compacting Apparatus
A control apparatus for a soil compacting apparatus such as a vibratory plate has a movable operating element for specifying a running direction of the soil compacting apparatus by way of an operator, and having a hydraulic master device, with a master cylinder, in which a master piston can be moved to and fro in a linear manner, in order to generate a hydraulic signal. A hydraulic connector serves for coupling hydraulic components of the soil compacting apparatus and for transmitting the hydraulic signal from the master device. A transmission device is provided for converting the movement of the operating element into a linear movement of the master piston, it being possible for the operating element to be moved between a first position (V) and a second position (R). The first position corresponds to a maximum forward movement of the soil compacting apparatus, and the second position corresponds to a maximum reverse movement of the soil compacting apparatus. A latching device is provided for releasably holding the operating element in a predefined position, for example the first position.
Drive for Apparatus for Screeding Concrete
An apparatus for steering and driving a concrete screed having a frame and a screed head secured thereto includes a plurality of spaced drive wheels rotatably and pivotably secured to the frame at a plurality of points, and a steering member coupled to one or more of the drive wheels for controlling the directional orientation thereof.
BATTERY-POWERED STAND-ALONE MOTOR UNIT
A stand-alone motor unit for use with a piece of power equipment includes a housing and a flange coupled to the housing on a first side thereof. A plurality of apertures through the flange defines a first bolt pattern that matches an identical, second bolt pattern defined in the piece of power equipment. An electric motor has a power output of at least about 2760 W. The motor includes a stator having a nominal outer diameter of up to about 80 mm and a rotor supported for rotation within the stator. A power take-off shaft receives torque from the rotor and protrudes from one of the flange or a second side of the housing. A controller is positioned within the housing and electrically connected to the motor. A battery pack for powering the motor has battery cells having a nominal voltage of up to about 80 V.
Drive system for screeding concrete
An apparatus for steering and driving a concrete screed having a frame and a screed head secured thereto includes a plurality of spaced drive wheels rotatably and pivotably secured to the frame at a plurality of points, and a steering member coupled to one or more of the drive wheels for controlling the directional orientation thereof.
COMPACTING POWER TOOL
A compacting power tool comprising: a housing; a motor; a reciprocating drive mechanism coupled to the motor; and a compacting foot coupled to the reciprocating drive mechanism and configured to engage a surface to be compacted; and a controller configured to receive at least one motor signal and to determine a change in the operational load of the motor based on the received at least one motor signal when the compacting foot is not engaging the surface to be compacted.
PLATE COMPACTOR
A plate compactor includes a base, a vibration mechanism coupled to the base, a compacting plate coupled to the base and configured to be vibrated in a vertical direction by the vibration mechanism, and a non-stick coating on a surface of the compacting plate. The compacting plate is configured to compact a work surface. The non-stick coating is configured to prevent a buildup of material on the compacting plate.
CONSTRUCTION EQUIPMENT TRANSPORTATION DEVICE AND METHOD
A vehicle-mounted transportation lift for transporting wheelless or trackless, powered, construction equipment and a method of using same; wherein the transportation lift comprises a cradle comprising a horizontally oriented plate, the plate removably secures to and supports a base of the powered walk-behind equipment; a lifting device that supports a motorized screw jack, the lifting device further being attached to an automotive vehicle; wherein the motorized linear screw actuator moves the cradle between a loading position proximate to the ground and a carrying position distal from the ground.
Motor apparatus, electric power unit, and working machine
The present invention provides a motor apparatus having a motor, comprising: a fan that is rotatably supported by a shaft member of the motor, and sends, in a centrifugal direction by rotation, gas taken from an axial direction of the shaft member; and a cover member that covers the fan so as to allow the gas sent in the centrifugal direction from the fan to flow along an outer surface of the motor, wherein the cover member has a blowout port that blows out some of the gas sent in the centrifugal direction from the fan in the centrifugal direction to cool an external mechanism of the motor apparatus.
