Abstract
A scarifier comprises skis that allow a drum assembly to contour with the concrete. Alternatively, the scarifier comprises at least two segments that are torsionally coupled to each other. Alternatively, the scarifier comprises the torsionally-coupled segments and the skis.
Claims18
A walk-behind scarifier, comprising:
- (a) a proximal segment, comprising:
- (a1) a rear assembly weldment;
- (a2) a handlebar mechanically coupled to the rear assembly weldment;
- (a3) an electrical enclosure secured to the rear assembly weldment;
- (a4) a battery tray mechanically coupled to the rear assembly weldment;
- and
- (a5) drive wheels for propelling the walk-behind scarifer;
- (b) a middle segment torsionally coupled to the proximal segment, the middle segment comprising:
- (b1) an engine;
- (b2) an engine mounting plate to hold the engine;
- and
- (b3) a drum assembly driven by the engine, the drum assembly to texturize a surface when the drum assembly contacts the surface;
- and
- (b4) a ski mechanically secured to the middle segment, the ski having an angle, the angle providing a contact point between the ski and the surface, the ski for to maintain a controlled elevation of the drum assembly with reference to the surface;
- and
- (c) a distal segment mechanically coupled to the middle segment, the distal segment comprising:
- (c1) a front bumper weldment;
- and
- (c2) casters on the front bumper weldment.
16 more elements
A scarifier, comprising:
- a first segment comprising drive wheels for propelling the scarifier, the first segment further comprising a fuel tank;
- and
- a second segment torsionally coupled to the first segment, the second segment comprising a drum assembly for texturizing a surface, the second segment further comprising an engine.
A scarifier, comprising:
- a drum assembly for texturizing a surface;
- a first ski located on a left side of the drum assembly;
- a second ski located on a right side of the drum assembly, the second ski and the first ski to maintain a controlled elevation of the drum assembly with reference to the surface.
