E-Z Drill’s Multi-Gang Slab-Rider Drills Offer Accuracy and Versatility
E-Z Drill offers a line of multi-gang slab-rider drills for accurate concrete drilling from an easily maneuverable machine. The compact frame design allows each drill to operate in a 4-foot patch while drilling to within 6 inches of a corner. The bits drill to a standard 18-inch depth, and each unit can be adjusted easily to drill into the center of a 24-inch slab. Contractors can adjust the gang spacing between 12 and 36 inches, with greater width settings available through custom orders.
The pneumatic drills, which are powerful enough to tow the air compressor with an optional tow-bar assembly, feature an internal regulator to prevent breakage caused by high-pressure spikes. When used with the tow bar kit, the SRA models eliminate the need for an additional vehicle. This enables one person to drill, move the machine and tow the compressor, saving labor and fuel costs. Additionally, a patented tri-steering feature simplifies maneuverability as the machine can rotate within its own radius without needing to be disconnected from the air compressor.
An auto-alignment feature allows operators to quickly reposition the drills after each hole set, resulting in the ability to drill more holes in a single day than competitive units. E-Z Drill's patented roller bearing feed system provides friction-free drilling. Each model also features an individual regulator that allows the operator to set the optimum drilling speed for each drill.
Like all E-Z Drill units, the multi-gang slab rider drills feature quick-release bit guides for fast changes with any bit style. Quick-coupler air fittings and easily replaceable carriages lessen downtime for repairs.
Slab-rider drills reference from the top of the concrete slab, which provides optimum accuracy and eliminates disturbance of the subgrade — a key requirement in many state contracts. An optional on-grade conversion kit makes the slab rider models more versatile for varying applications since it can reference from the subgrade when the top of a slab is not available. For additional versatility, the slab-rider models can drill vertically after just a few adjustments. This makes the machine useful for mud jacking and under-sealing applications.
A number of features built into the slab rider models contribute to durability and long service life. Multi-point oil injection lubricates each drill individually from a single reservoir to ensure they always have the proper amount of oil. This helps the drill motor last longer than with a central oiling system, which doesn't offer individual lubrication adjustments. An automatic drill shutoff further extends each drill's life by preventing "dry-firing." Foam-filled tires with heavy-duty spindles eliminate flat tires and prevent breakage.
For operator safety, E-Z Drill features carriage locks to keep the drills and bits in place when the air supply is off or disconnected. Additionally, auto-locking air couplers keep the air supply hose on the drill coupling without the connection being manually pinned. A lifting point built onto each unit ensures the drill is balanced when being loaded and unloaded.
As one of the latest models in the R2-Series excavator lineup, the Bobcat® E88 delivers durability, performance and quality for more productivity. Technically speaking, it's a compact machine, but it brings big performance with its redesigned engine and optimized lift performance, plus undercarriage and counterweight improvements. All these enhancements make this excavator one of the highest-performing models in its size class. With impressive over-the-side lift capacity, you can dig with greater confidence over the side of the machine. Put it to the test against similar models from other manufacturers. You'll see that the E88 can outwork the competition.
