Screedemon #WS500 w/ Honda GX35 Motor (MBW)
Special Instructions:


WS500 ScreeDemon Power Unit Honda GX35 Motor

  • Lightweight, extra rigid, double triangular magnesium bar construction minimizes variability in vibration.
  • Sealed exciter requires no maintenance.
  • Hand/arm vibration is 70 to 90% less than the competition, without compromising control of the unit.

When MBW develops a new product, we look for deficiencies in products already in the marketplace. Portable wet screeds suffered 4 serious shortcomings:

Wet screeds were prone to high maintenance, especially in drive mechanisms between the engine and exciter. The ScreeDemon employs a simple, durable, low cost rubber isolator to drive 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. No holes to weaken the screed bar. No threads to complicate assembly/disassembly. The ScreeDemon goes together and comes apart in seconds.
