Provided is a utility vehicle that can efficiently take the traveling wind into a vehicle and discharge muddy water and earth and sand that enter a passage for taking in the traveling wind to the outside of the vehicle. The utility vehicle includes an opening formed on the vehicle body, the opening through which a traveling wind can be taken into the vehicle body when the vehicle body travels, a radiator capable of cooling a coolant for cooling a driving source by exchanging heat with the traveling wind taken in from the opening, a passage that is provided between the opening and the radiator and guides the traveling wind taken in from the opening to the radiator, and a discharge mechanism that performs discharge operation to discharge foreign matter to outside when the foreign matter enters inside of the passage together with the traveling wind.

A system is used to implement a method of heating an undercarriage of a vehicle. The system includes a vehicle with a controller, at least one heater, at least one positioning mechanism, and an undercarriage. The controller receives and processes each command and reading. The at least one heater applies heat for a desired area of a vehicle in order to melt snow and ice. The at least one positioning mechanism physically extends and retracts the heater. The undercarriage is the frame of vehicle that upholds and supports the rest of the vehicle. The method begins generating an activation command for the heater with the controller. The heater is moved from the retracted position to a deployed position in an accordance to the activation command with the positioning mechanism. A quantity of thermal energy is emitted in accordance to the activation command with the heater.

A rock knocker bracket holds a rock ejector such as a chain or bar that is used to clear debris from the gap between two tires of a mining vehicle. The rock ejector is pivotally mounted on a horizontal, lateral pin that is held at both ends by side plates of the bracket. The pin has a series of holes formed along its length. Bar retainers and washers mounted on the pin allow the rock ejector to be moved laterally along the pin and thereby provide for different laterally spacing configurations of the tires. Fasteners pass through holes in the bar retainers and the holes in the pin to hold the rock ejector at a predetermined lateral location along the pin. Alternative designs for the pin and the bracket include other systems for laterally moving the rock ejector and mounting it in the predetermined lateral position.

A wheelchair wheel cleaning assembly includes a clamp that has a space integrated therein to insertably receive a frame of a wheelchair. A pair of fasteners is each extendable through the clamp to attach the clamp to the wheelchair. A lever is pivotally coupled to the clamp and the lever is positionable between an engaging position and a disengaging position. An arm is coupled to and extends laterally away from the lever and a leg is in communication with the lever. An arm scrubber is disposed on the arm to scrub the rear wheel of the wheelchair when the lever is in the engaging position. A leg scrubber is disposed on the leg to scrub the front wheel of the wheelchair when the lever is in the engaging position.

A wheel brush for a wheelchair has a brush assembly that is slidably disposed within a main housing and biased therein via a spring. A brush head is held within one end of the brush assembly so that a portion of the bristles of the assembly extend beyond an open end of the main housing. The device is attached to a brake arm of the wheelchair via a mount member that has a channel such that the brake arm is received within the channel. The wheellock assembly pushes the device toward a rear wheel of the wheelchair such that the bristles engage the wheel and brush dirt off the wheel as the wheelchair rolls being biased thereonto by the spring. The mount member acts as the brake arm for the wheelchair.
