Description
Structural ASTM gray iron castings provide the massive dampening weight required to eliminate blade chatter during deep masonry passes. The Crown Construction Equipment Block Brick Saw slices jumbo cinder blocks and hard stone pavers. A 13 HP Honda engine spins twenty-inch blades down to eight-inch depths. The heavy four-hundred-pound frame requires dedicated mechanical hoist rigging to load into trucks.
Heavy welded structural steel plate forms the main chassis tub, while cast iron forms the rigid pivot head and arbor bearing carriers. The 13 HP Honda GX390 gas engine produces 11.7 net HP at 3,600 RPM, driving the arbor through triple V-belts. Bare tool weight hits 420 lbs, requiring a 58 by 30 by 62 inch shop footprint for safe operation.
Key Features of Crown BBS20-GH13
Masonry supply yards and commercial block layers deploy this stationary saw to trim structural CMU blocks, split-face veneers, and landscape retaining wall units. Contact commercial distributors for current pricing to buy Crown BBS20-GH13 saws for tough masonry fabrication.
- Honda GX390 thirteen horsepower engine powers twenty-inch diamond blades without bogging down.
- Eight-inch maximum cut depth accommodates standard eight-inch concrete blocks in single passes.
- Triple V-belt drivetrain transfers engine torque down to the cutting spindle without slip.
- Heavy conveyor cart rolls along machined steel tracks on sealed dual-flanged ball bearings.
- Mechanical foot pedal control permits hands-free plunge cutting through thick stone blocks.
- High-volume submersible water pump floods diamond cutting rims to wash away slurry grit.
- Rigid cast iron pivot block holds cutting head alignment under aggressive plunge downforce.
- Forklift access channels welded under the lower chassis tub make yard transport fast.
Arbor Runout Carriage Travel Tolerances
Arbor runout measures 0.0008 inches TIR across the 1-inch blade mounting collar. Under heavy plunge passes through hard granite stone, the Honda GX390 drops from 3,600 RPM to 3,410 RPM without engine stumble. Table carriage deflection stays under 0.003 inches when carrying a 110-pound architectural concrete block across its twenty-four-inch travel stroke. Triple drive belts exhibit zero slip when tensioned to manufacturer deflection specifications. Water delivery output measures 10 GPM at four feet of total dynamic head.
Masonry Yard Ergonomics Maintenance Realities
The foot-pedal plunge mechanism allows operators to use full leg leverage when chopping through dense structural block, keeping back and arm strain low. The cart table glides along machined tracks with light hand push pressure. Do not buy this saw for hand-held field work or shallow four-inch residential tile cuts. Masonry supply yards, block plants, and large commercial masons extract outstanding production efficiency here.
- Grease arbor shaft pillow block bearings every twenty hours using lithium grease.
- Shovel accumulated mortar and stone sludge from the lower tub every week.
- Check triple V-belt tension and belt wear after fifty operating hours.
