The invention relates to an apparatus and method for utilization of a proximity sensor to control the height adjustment of vehicle-mounted devices for use in clearing snow or debris from a road or runway. One end of a shaft is connected to the broom, while the other end is mounted on top of the broom assembly. A threaded collar on the shaft moves axially in response to change in the height of the broom assembly. A proximity sensor produces and monitors a magnetic field near the central portion of the shaft. Height adjustment of the broom causes the collar to move past the proximity sensor, thereby distorting the magnetic field. The proximity sensor stops the electrical signal which controls the downward movement of the broom assembly. The height selection for the broom assembly is adjusted by turning a nut or ratchet assembly on the end of the shaft.

The control apparatus and vehicle of the invention for controlling a broom and blower system attached to the vehicle typically includes several modules (which may be software, hardware, or a combination of these) which interact to process command inputs. Thus, broom state, broom height, and broom direction command modules are all logically connected to a command input module. Similarly, blower state (blower on/off) and direction (blower left/right) modules are also logically connected to the command input module. The method of the invention for operating a broom and a blower includes the steps of receiving a command input, measuring the duration of the command input, and determining whether the command input is a broom state command, a broom height command, a broom direction command, a blower state command, or a blower direction command. If the command is one which requires selection of an intermediate position, then the command is followed as long as the command is entered. If the command is of a relatively short duration, then the command input is latched and held for the length of time required to reach a full-stop position.

The invention relates to an apparatus and method for reducing the wobble tendency in an axle-mounted caster wheel assembly on a vehicle-mounted broom system. The caster wheel is mounted on an axle which is connected to a yoke. The yoke is attached to an upwardly extending column member. Movement of the column member is controlled by an adjustable braking mechanism located at the top of the column member. A rigidly-mounted tubular housing surrounds the column member and a threaded rod is mounted in the top of the column member. Tightening of a jam nut located on the top of the threaded rod exerts compressive force on an expandable bushing located between the column member and the tubular housing. Such force provides frictional contact with the column member, thus reducing the movement of the column member and yoke, thereby reducing the wobble of the caster wheel assembly.

The invention relates to a system and method for constructing a vehicle-mounted single core broom system for use in clearing snow or debris from airport runways. The rotatable broom system utilizes a single piece hollow tubular core which is attached to the front of the vehicle. A low speed/high torque radial piston hydraulic motor is mounted inside one end of the broom core. The motor case rotates as the motor operates. Because the motor case is directly connected to the broom core, this rotation causes the broom core to rotate. A rotatable mounting is attached to the opposite end of the broom core. The broom core is 46 inches in diameter and dynamically balanced. These features enable higher broom tip speed and improved sweeping efficiency. Linear bristle cassettes are slid horizontally into the broom core sections, facilitating easy removal and replacement of the bristles as they become worn.
