DIRECT DRIVE vs. PLANETARY MACHINE

DIRECT DRIVE - energy and efficiency is maximized while amp draw and friction loss is minimized vs. a planetary gearbox which spreads to 2, 3 and more heads.

Maintenance is simple and minimal.

PLANETARY DRIVE - design is used to increase RPM for polishing.  With the increase in RPM, Torque decreases.

 

Hawk GP26 Grinder - made in USA.USA Engineered Design

  • Dual Voltage:  120 or 240 Volt, easy to switch from 120 to 240 volt, 14.9 maximum amp draw @ 120 volt

  • Control Center is front & center to the operator

  • Floating head - ensures the tooling grinds and scrapes flat and fast, follows the floor’s contour, prevents dig and ring marks
  • Powered by a TEFC (Totally Enclosed Fan Cooled) Motor - motor is protected from dust, debris, slurry
  • 11:1 Gear Ratio - high torque to drive scrapers & metal diamonds
  • 3-position handle adjustment for transport, operation and storage

  • Detachable handle-carriage for transport

  • Dual AC-TEFC Motors with 11:1 XHD gears

  • Removable collar weights

  • Built in dust control with 2" exhaust port.

Know Your Market  The type of equipment needed starts with understanding the project size and your target market [i.e. concrete polishing vs. coating removal and grinding.]

Concrete Grinders  Can be characterized as planetary or rotary.  Understanding the difference between the two technologies will enable you to choose the right grinder to smooth, prep, level or polish a concrete floor.

Planetary Gearbox
  • Gear design allows the grinder to move in a straight line across the floor with relative ease, which means greater flexibility and less struggle for operators

  • Best used on less aggressive jobs such as smoothing out a concrete floor or preparing smaller floors for an epoxy coating

  • Gearbox is spread to 2, 3, 4 and more heads, the design typically provides more torque during starting and then transferred to increased RPM speeds for polishing.

Summary:  Best for polishing.

Rotary - Direct Drive
Wheels-Down
  • Gear design is a direct connection from the motor to the grinding head which maximizes energy and efficiency while reducing amp draw and avoids friction loss and wear that occurs with an offset planetary gearbox

  • Maintenance is minimal and the purchase price is less because the planetary gearbox is eliminated.

  • Direct connection from the motor eliminates belts and pulleys that are in planetary grinders

  • Design optimizes the grinder's weight and rotational speed while maintaining high torque which a planetary grinder does not

  • Skilled and unskilled users can take advantage of the direct drive / wheels-down design to perform more intensive tasks such as removing heavy mastic or thick layers of paint from a concrete surface.

Summary:  Best for grinding, coating removal & polishing.

 

 

 

Diamond Driver Plates, 13" (2)Diamond Driver Plate
--- Two (2) 13" diamond driver plates (right) are included with the GP26.  Plates accept a complete assortment of tooling (shown below) to grind, remove coatings, polish and scarify concrete, granite and marble floors.

PLATE FEATURES:

  • Hawk GP26 Grinder - driver plate assembly.3/8" steel plate, powder-coated for corrosion resistance and easy cleaning

  • Damping isolators built-in to reduce vibrations and provide flex over high points and lippage

  • 3" round diamonds and standard size trapezoid tools are held securely in place by milled recesses and industrial magnets - tools are easy to change

  • Plate includes steel blanks, round and trapezoid, that fit in the unused recesses to prevent the unused openings from filling with debris

  • Equipped with metal 3-keyway clutch plate, the industry standard for rotary grinders and buffers - prevents bodily injury and damage to the plate and grinder
