Wet screeds were prone to high maintenance, especially in connection to drive mechanisms between the engine and exciter. The ScreeDemon has no metallic shaft connection. A simple, durable, low cost rubber isolator drives the eccentric.
Most screed and screed bar combinations produce irregular vibration along the length of the screed bar. Not only is the concrete exposed to highly variable levels of vibration but cream levels vary from spot to spot along the screed bar. The back-to-back triangular construction of the ScreeDemon bar is extremely rigid and minimizes variability in the transmission of vibration.
Most screeds bolt to their screed bars. Hardware threads are compromised by the concrete and assembling or removing the screed becomes such a problem that crews often don't disassemble for cleaning or transport. The ScreeDemon simply clamps to the specially designed bar. The sceed deamon is powered by a small honda 4 stroke engine . In ideal conditions this machine operates in concrete of 80 plus of slump where concrete is self levelling ?
