Atlas Copco SMART pokers give contractors an efficient and convenient method to eliminate air voids in concrete. The pokers have a radius of action that is 12 times the diameter of the poker heads rather than the standard 10, so they work faster to remove air. And, because they are electric, they are a convenient option on construction jobsites powered by electricity or generators.
The SMART pokers are available with 1-7/8 inch and 2-3/16 inch poker heads. Their radii of action allow contractors to work in areas as large as 22 inches in diameter, which minimizes the number of dips. The pokers also operate with high centrifugal force and amplitude to provide as many as 12,000 vibrations per minute. This combination of forces allows contractors to achieve optimal concrete density in nearly half the time as traditional pokers for maximum productivity on any job.
The SMART pokers use a convenient plug and poke system, which means users can simply plug them into to a 120-volt outlet and get to work. The 230-volt pokers feature a built-in frequency converter that eliminates the need for an additional converter to adjust the frequency. And, because the pokers operate with electricity, no gas fumes are emitted, which makes them ideal for work on indoor projects or in confined spaces.
For easy maneuverability on the jobsite, the SMART pokers come with 32.8 feet of electrical cable and 16.4 feet of hose, with longer hose options available. Thanks to aluminum housing, the pokers weigh just 35 pounds — 30 percent lighter than traditional units with steel housing.
Atlas Copco designed the SMART pokers with a motor-in-head design. This helps keep vibrations in the poker head, which allows contractors to work more comfortably. The SMART pokers also feature an “E” pistol design for an easy, comfortable grip.
Sealed stators on the SMART pokers prevent accidental shock, which occurs if excess moisture gets in the motor. This thermal protection also prevents electrical overload and overheating, which damages the motor and built-in frequency converter. Additionally, thermal switches detect electrical issues and automatically shut off the poker to prevent damage. The thermal switches also prevent the pokers from automatically starting after a power outage, which can cause concrete to segregate.
To minimize the need for routine maintenance, Atlas Copco constructs the pokers without a shaft. Each poker also comes with a complete service kit. The kits include components such as O-rings and ball bearings for fast and easy onsite maintenance with minimal downtime.
