Elgin Sweeper Introduces Crosswind Specialty Track Sweeper for Racetrack Sweeping
The modified Crosswind® Specialty Track Sweeper from Elgin Sweeper debuts at NASCAR racetracks around the country, beginning with the Daytona 500 on Feb. 24. The sweeper plays a supporting role in a new initiative to dry rain-soaked racetracks.

The regenerative air Track Sweeper adapts features from Elgin Sweeper’s highly successful Crosswind GRS (glycol recovery sweeper), a special-purpose sweeper used to vacuum liquid glycol from airport runways. This specialty sweeper includes unique features developed for racetrack sweeping and maintenance applications, such as a side air-blast nozzle, a reverse sweep system, a 20,000 CFM-rated blower and a hydraulically-
During track testing conducted in conjunction with NASCAR last November in Daytona, this same vacuum technology proved to efficiently vacuum water from the pores of the racetrack, and worked even better with the new track-drying technology designed by the NASCAR Research and Development Center. Working together to remove moisture from the track surface, both technologies dramatically accelerated the drying time.
Developed as a more effective alternative to the current track-drying method, the system, featuring the Crosswind Track Sweeper, is expected to expedite the process.

“Elgin Sweeper’s Crosswind Track Sweeper has the potential to dramatically reduce the number of NASCAR races postponed or shortened due to wet weather conditions,”
The Crosswind Track Sweeper can clean a wide, 117-inch path with its side broom and pickup head, using a 20,000 CFM-rated blower to provide a high-volume air knife to blast air while picking up debris, oil-dry and standing water. With its side air-blast nozzle, debris can be blown off the track for distances up to 50 feet. The sweeper has a generous 8-cubic-yard hopper to contain ample track debris and water. The Freightliner M2 chassis features dual controls for operation from either the right- or left-side of the cab. The sweeper features dual engines, a 115 hp turbocharged diesel for the sweeper and a 200 hp diesel for the chassis. For enhanced visibility, the sweeper and its chassis are equipped with a multiple array of amber safety lights. For remote cleaning of the bigger jobs, such as an impact to a sand barrel attenuator, the unit also features a soft wall cleaning attachment and a large jib boom-mounted 8-inch rear vacuum hose.
The specialty sweeper was modified with input from racetrack officials in the NASCAR circuit. Elgin Sweeper representatives – along with Jeff Miles from Key Equipment & Supply Company (http://www.keyequipment.com/
A lifelong racing enthusiast, Miles is also a lead driver for the Richard Petty Driving Experience and has logged more than 350,000 miles in NASCAR-style stock cars. Traveling to tracks across the country has given Miles an added appreciation for clean track conditions.
In 2001, Miles had the opportunity to sweep the second layer of race surface at the new Kansas Speedway to help prevent airborne dust during a locally televised test session. “My racing experience gave me the chance to see first-hand the different tracks and their sweeping programs and challenges. It also led to several design ideas for a sweeper that not only excelled on a racetrack surface but also worked efficiently around a racetrack complex,” Miles said. “We wanted the Crosswind Track Sweeper to be a multi-purpose sweeper that could vacuum water, blow oil-dry off the track and sweep. The Track Sweeper is definitely not a smaller parking lot sweeper.”
For more than a year, Elgin Sweeper conducted testing to develop a new side-air blast nozzle on the Crosswind Track Sweeper, collaborating with the California Motor Speedway. To verify that the sweeper will operate effectively on the steep banks and inclines associated with various racetracks around the country, Elgin Sweeper conducted additional testing for maximum tilt angle at the Caterpillar, Inc., research facility in Peoria, Ill. An in-cab angle measurement system on the Track Sweeper audibly and visually alerts the operator when steep incline conditions approach the maximum tilt angle.
Side air nozzle
The new air blast nozzle on the Crosswind Track Sweeper was designed using computer-aided design (CAD) modeling, computational fluid dynamics (CFD) analysis and internal testing which streamlined the process for validation of maximum potential air velocity to move more debris to further distances. The new design incorporates linkage that allows the operator to adjust nozzle tilt and includes in-cab control to further maximize productivity and safety, eliminating the need for the operator to exit the cab during a ServiceMaster Clean Caution period. The side air nozzle delivers more airflow at higher velocities.
The powerful, 20,000 CFM-rated blower is ideally suited for locations where jet dryers can’t be used, such as grass on the inside field, pit areas and weepers (cracks on a racetrack where water seeps through). The blower volume, nozzle height and angle can all be controlled, making the sweeper even more maneuverable and responsive.
To improve visibility from the sweeper cab when operating in reverse, Elgin Sweeper has standardized back-up cameras on all sweepers. For improved productivity and safety on the racetrack, Elgin Sweeper integrated this feature on the Crosswind Track Sweeper with the reverse sweep system, allowing the operator to safely use sweeper functions while moving in reverse. This system includes additional safety lighting, an increased decibel rated back-up alarm and a rear object-detection sensor that can see through dust, rain, daylight and darkness to detect any objects or pedestrians behind the sweeper.
“This system greatly improves the operator’s awareness of the surroundings while sweeping on the racetrack and in the heavily populated pit areas,” Crockett said.
In addition to sweeping the racetracks, the Elgin Sweeper Crosswind Specialty Track Sweeper can also quickly and efficiently remove standing water, rubber and debris in and around the pit area, which contributes to the overall safety of the racers, their crews and spectators.
According to Crockett, the speed and maneuverability of the Crosswind Track Sweeper ensures prompt response on and off the track. “This sweeper can get from job to job and make quick work of any sweeping challenges that come up before, during and after a race,” he said.
