A material collection system is provided. The system can include a vehicle, a conduit, a vacuum generator mounted to the vehicle to develop an airflow and to draw material into the conduit, and a moveable boom mounted to the vehicle to support the conduit. The system can include a control system to control a speed of the vacuum generator.

A system for detecting and locating sand accumulation in an enclosure and for removing the detected and located sand accumulation, having a sand accumulation locator assembly adapted to detect and locate one or more accumulations of sand in the enclosure; a sand removal mechanism adapted to remove the detected one or more accumulations of sand; and a controller communicatively coupled to the sand accumulation locator assembly and the sand removal mechanism, said controller being adapted to: control the sand accumulation locator assembly to detect and locate the one or more accumulations of sand in the enclosure; and control the sand removal mechanism to remove the one or more detected accumulations of sand based on corresponding one or more locations of accumulated sand detected by the sand accumulation locator assembly.

A material collection system is provided. The system can include a vacuum generator having a fan to develop an airflow and draw material into a conduit. The system can also include a transmission, a power source to selectively power at least one of the vacuum generator and the transmission, a variable power divider to divide a power output from the power source to the transmission and the vacuum generator, and a control system to control the variable power divider in a first mode and a second mode.

A material collection system is provided. The system can include a vehicle, a conduit, a vacuum generator mounted to the vehicle to develop an airflow and to draw material into the conduit, and a moveable boom mounted to the vehicle to support the conduit. The system can include a control system to control a speed of the vacuum generator.

A boom hose apparatus for a material collection vehicle includes a telescoping boom assembly and a hose assembly supported by the boom assembly. The boom assembly includes a plurality of telescoping conduits. A flexible hose is received through the telescoping conduits and can slidably extend from, or retract into, the conduits independently from the telescoping of the conduits.

Disclosed is self-propelled equipment for street sweeping and/or weeding, where modifications were made to the cleaning system of the filters, the battery for driving the motors with electric start, front fairing assembly over the turbine, combustion or electric motor, debris suction pipe, hydraulic components, headlights, motor protection and brooms and motors for each front wheel and telescopic brooms that will act at a 180 angle by sweeping away debris from the sidewalk or even from the street ahead of the main brooms.

A handheld work apparatus has a blower wheel. The blower wheel is held via a nut on the shaft in a manner locked against rotation by frictional force. A thread moment of friction is transmittable between the nut and the shaft via a thread section. A first moment of friction is transmittable between the nut and the blower wheel via a first friction contact surface. The first friction contact surface is configured such that, at a minimum tightening torque of the nut, the first moment of friction is greater than the thread moment of friction. As a result, during the operation of the work apparatus when there is a relative movement between the blower wheel and the shaft, the blower wheel moves the nut along therewith. The nut retensions the blower wheel against the shaft. The second friction contact surface runs conically with respect to the rotational axis.

A debris deflecting system for a milling machine includes at least one deflecting element disposed proximate to a component of the milling machine. The deflecting element is configured to deflect debris away from a front end of the component. The component includes at least one side plate of the milling machine and/or at least one sensor of the milling machine. The debris deflecting system also includes at least one actuating element coupled to the deflecting element. The actuating element is configured to actuate the deflecting element to deflect the debris away from the front end of the component.

A material collection system is provided. The system can include a vehicle, a conduit, a vacuum generator mounted to the vehicle to develop an airflow and to draw material into the conduit, and a moveable boom mounted to the vehicle to support the conduit. The system can include a control system to control a speed of the vacuum generator.

A debris management vehicle is disclosed that has a vehicle frame and a fan assembly coupled to the vehicle frame. The fan assembly has a rotor axis oriented obliquely to a horizontal plane. A nozzle defines a nozzle inlet and a nozzle outlet. The nozzle inlet is in fluid communication with an outlet of the fan assembly. The nozzle outlet is rotatable about a nozzle axis that is orthogonal to the horizontal plane.
