17" & 20" - High Torque Low RPM

1. Direct Drive Gears ( vs. planetary belt-drive):

   • Direct connection from the motor to the grinding head:

     • maximizes energy and efficiency

     • reduces amp draw by avoiding friction loss, wear and ongoing maintenance vs. planetary belt-drive grinders

   • Maintenance is minimal if any vs. constant maintenance and expensive repair cost with a planetary grinder

   • Direct drive connection from the motor to the drive plate eliminates belts and pulleys from breaking (i.e. used in a planetary grinder)

   • Direct- gear drive design optimizes the grinder's weight and rotational speed

   • APPLICATIONS:  HD, High Torque Concrete Grinding, Coating Removal, Scarify Concrete, Polishing, Maintenance.

2. Wheels-Down Machine ( vs. Wheels-Up "Swing Machine"):

   • With a wheels-down machine, it takes minutes to master

   • A wheels-up or swing machine, they're harder to control, requires a long learning curve, often taking days to master.

Overview - both sizes:

• 11:1 Gear Ratio with Triple Extra HD, Helical-Cut Industrial Gears - provides the high torque to drive scrapers & metal diamonds with minimal amp draw
• Wheels-Down Machine - productivity improves 100% vs. using a wheels-up or so-called swing machine.  With a wheels-up (swing machine) you are constantly fighting against its swing movement especially during high torque grinding and coating removal projects;  additionally, there’s a long learning curve to master how to use or control a swing machine
• Powered by a TEFC (Totally Enclosed Fan Cooled) Motor - motor is protected from dust, debris, slurry
• Floating head - ensures the tooling grinds and scrapes flat and fast, follows the floor’s contour, prevents dig and ring marks
• 360° Internal Dust Pick-Up - collects airborne dust and debris in the brush cover and directs it upwards to the 2" vacuum port.

Features

• Dual Voltage:  120 or 240 volt, easy to switch - 7.9 maximum amp draw @ 120 volt

• Foot Operated Tilt Back for Easy Transporting

• Dual steel operating triggers with negative pressure on/off switch

• Disassembles for easy handling down stairs

• 2" x 8" non-marking load bearing, ball bearing wheels

• Thumb-operated safety switch with comfort cushion grips

• Includes removal weights with (4) 20 lb plates and locking pins
• WHEELS-DOWN vs. WHEELS-UP (i.e. swing machine, photo right)
  • Swing machines are used in the janitorial profession to buff and wax floors, it takes time to learn how to control a Wheels-Up machine, the learning curve is long.
  • For concrete grinding and coating removal - high torque is required and a Wheels-Down machine eliminates the learning cuff and a worker's muscle to control the machine.  With a Wheels-Down machine, unskilled workers can become experts within minutes and worker fatigue is reduced 120%.
• PORTABLE - EASY TO TRANSPORT:  One man handling through doorways, down stairs, across rough terrain
• OPTIONAL DIAMOND DRIVER PLATE - Accepts all the diamonds to grind, scarify, remove coatings, polish concrete and stone floors.
