COLD AIR BLOWER WITH SELF-SUPPORTED BOOM

摘要

A cold air blower for removing debris from a ground surface that includes a boom rotatable between multiple operating positions and a stowed position. The boom is mounted to a power unit mounted to the vehicle chassis such that the boom is rotatable between at least a front-facing, operating position and a rear-facing stowed position. The boom includes a top tube and a discharge tube that includes a discharge nozzle. The combination of the top tube and the discharge tube are rotatable about the power unit such that the discharge tube is positioned behind the midpoint of the vehicle chassis in the stowed position. The nozzle on the discharge tube can be operated to automatically and continuously rotate between a first pan position and a second pan position. The boom can be rotated between opposite first and second side positions that extend perpendicular to the vehicle axis in opposite directions.

主权项

1. A cold air blower for removing debris from a ground surface, comprising:
a vehicle chassis having a front end and a rear end and extending along a vehicle axis between the front end and the rear end; a power unit mounted to the vehicle chassis, the power unit including a blower operable to generate an air flow; and a boom positioned to receive the air flow from the blower and direct the air flow through a nozzle onto the ground surface, wherein the boom is movable between a front position in which the boom is parallel to the vehicle axis and the nozzle is forward of the front end of the vehicle chassis and a stowed position in which the boom is positioned at an angle relative to the vehicle axis and the nozzle is positioned behind a midpoint of the vehicle chassis between the front end and the rear end.
