Polishing Concrete, Concrete Polishers, HTC

The new HTC 800 HDX has four heads, instead of three. Its hydraulic-assisted integrated weight system replaces stackable horseshoe weights that had to be placed by hand. The weights are shifted on or off the heads via a three-position slide switch that also includes a setting for actively weighting the heads away from the surface, a handy feature for use on polishing resins.

The improved model also features a heavier grinder that adds 336 pounds to the machine for a total weight of 1,150 pounds. Its sleeker design incorporates integrated hoses; its 20-horsepower motor is 5 hp stronger than its predecessor; and its hub-type heads last three times longer than the bearing-type heads on the 800 HD and other planetary grinders. Two of the four heads spin clockwise and two counterclockwise, canceling out the force that is otherwise placed on the operator's arms.
