Model DST-6® Street Sweeper

The TYMCO Model DST-6, the industry’s first full-sized dustless sweeper. The DST-6 removes dirt, dust and debris from the sweeping surface, and uses filters that have a Minimum Efficiency Reporting Value (MERV) 16 Rating, meaning they are able to capture a minimum of 95% of 0.30 micron and larger size particles, far exceeding PM10 requirements.

TYMCO's patented filtration system enables the DST-6 to be equally efficient in wet or dry conditions, so you don't have to avoid puddles and leave debris behind. Our DST System when coupled with our Regenerative Air System produces the most technologically advanced street sweeper available today.

The DST-6 sets the performance standards for particulate matter removal in the U.S. and Canada. Mounted on a highly maneuverable cabover "standard truck chassis," the DST-6 can travel to the job site at legal speed limits and then perform the dustless cleaning required in industrial and municipal applications.


The dustless features are engineered to allow the sweeper to perform in all types of weather conditions with no operator adjustments required.

TYMCO Sweeper Design


TYMCO Sweepers are designed in way that truly reflects the culture at TYMCO.  When our engineers approach a challenge or a need on the sweeper, they work to develop straightforward solutions.  For example, all TYMCO Sweepers use True Regenerative Air.  This design delivers the simplest approach as well as the highest performance with the lowest downtime as compared to other sweeper technologies.

  • True Regenerative Air
  • Smart Gutter Broom
  • Operator Friendly Design
  • Easy Access to Components
  • High Productivity
  • Low Maintenance

More About TYMCO Sweeper Design

Features


Broom Assist Pick-Up Head

The TYMCO Model DST-6 pick-up head has a width of 87 inches and is equipped with a broom in the pick-up head for applications where a broom is desired. The fast rotation of the broom loosens packed-on debris and projects it into the Regenerative Air stream for effective cleaning.

With in-cab controls that allow broom-assisted sweeping only when needed, the operator can lift the broom out of service for regular use of the powerful Regenerative Air system.

Hopper

The Model DST-6 hopper is over 7.3 cubic yards in size with a useable capacity of over 6 cubic yards. Stationary hopper dumping system designed for safe, simple dumping and low maintenance.

This eliminates dumping cylinders and hoist, hydraulic controlled door latch assemblies, additional hydraulic door opening cylinders, grease zerks, and safety concerns such as pinch points and overhead clearance issues.

Gutter Broom

Gets debris out of the curb/gutter with large 43" diameter gutter brooms with in-cab control. Tilt gutter broom allows you to reach down into the deepest gutters.

TYMCO's large 43" gutter broom design has a pressure-sensing sequence valve to automatically determine the digging pressure needed for different debris; therefore, customers get maximum broom bristle life and cleaning performance.

From inside the cab, the operator can control the speed of the gutter brooms. This allows the operator to match the speed of the truck while sweeping to lessen the least amount of dust being kicked up.

Dust Control

TYMCO incorporates a high efficiency multi-pass cylindrical centrifugal dust separator for maximum particulate separation and sweeping performance. Designed for easy clean out and maintenance.

On board 220 gallons of water for dust control around the gutter brooms and inside the hopper. For below freezing conditions, the sweeper will continue sweeping dustless without using water.

DST System

The small amount of air that is diverted from the system to achieve the dustless effect is filtered through TYMCO’s patented DST system. The DST System will filter the diverted air through a pre-cleaner and cartridge filters. These filters have been determined through independent laboratory testing using the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 52.2 testing standards to have a Minimum Efficiency Reporting Value (MERV) 16 Rating, meaning they are able to capture a minimum of 95% of 0.30 micron and larger size particles. That is 1/200 of the diameter of a human hair! The best part is that both the pre-cleaner and cartridge filters are washable, ensuring long service life.

Power Unit

The Model DST-6 sweeper is powered by a 99 horsepower John Deere auxiliary engine. This engine powers all hydraulic functions through a gear driven pump and directly belt drives the blower wheel.

Blower Wheel

We use a natural rubber coated aluminum blower wheel which we have found ti be abrasion resistant as well as reduces fuel consumption because of its lightweight design.

Options


Camera/Monitor System

Cities, streets, and roads are full of cars, maintenance equipment, signs, light poles, trees and many other objects that need to be seen when backing up. The rear view back-up camera with in-cab display allows the operator to view the area behind the Model DST-6 while backing up providing additional safety and peace-of-mind to both Model DST-6 operators and owners. Additional cameras are also available to view the pick-up head and gutter brooms.

Drop Down Gutter Brooms

Allows for the gutter brooms to "drop down" in front of the pick-up head so the metal bristles can scrub up extremely packed on material. Also allows very tight sweeping of curb lines to minimize amount of dust being kicked up before it is swept by the pick-up head.

Stainless Steel Hopper and Dust Box

For maximum corrosion and salt spray resistance all interior hopper body sheet surfaces to be fabricated with low carbon, high chrome stainless steel.

The hopper weldment, hopper door, skimmer hood, hopper screen and dust box assemblies are included in these options. Dust separator inlet scroll and door are not stainless steel. Stainless steel bolt-on blower housing, and dust separator are also available

Pick-Up Head Curtain Lifter

Hydraulic actuated and retractable roller assembly that provides the pick-up head with the ability to sweep large volume of light debris. Electronically controlled in cab.
