Wet screeds have historically been notoriously temperamental and susceptible to mechanical failure, primarily because of their extended drive connection between their engine and exciter. The ScreeDemon™ design ingeniously eliminates this renowned vulnerability by connecting its engine to the eccentric drive via a durable, low-cost rubber isolator, rather than by the longer, wire-wound metal shaft favoured by others, which is also regular maintenance and is prone to accidental damage too.

Unlike some other competitor walk behind screeds which favour a 2-Stroke engine, the WS501H ScreeDemon™ is powered by the more powerful and more reliable Honda GX35 4-Stroke petrol engine. Some competitor models also use bolts to attach their beams/blades to their screed drive unit. The ScreeDemon™ is designed to assemble and disassemble in seconds and has a different beam design and mounting arrangement which facilitates this.

The bolt arrangement used on many other competitor screeds to mount their beams/blades is often prone to the associated hardware threads becoming compromised through contact with wet concrete, making assembly, dismantling and interchanging beam lengths and blades more time consuming and problematic. The ScreeDemon™ clamping system is designed to eradicate this and furthermore means that beams which are free from holes and/or cut-outs which also can weaken their structural integrity. It also enables ScreeDemon™ beams to be mounted offset to the drive unit, thereby making it easier to navigate around obstacles and under protrusions. ScreeDemon™ beams because of their unique design can also often be shortened and reused as they wear (which invariably at their ends caused by the constant friction caused with being in contact with formwork). This is in contradiction to most other competitor blades and beams which are simply discarded and worn away due to wear.

The WS501-H is equipped with a sealed exciter with oversized bearings which requires no maintenance. Its’ walk-in design allows easy access to lifting points, whilst its cast aluminium frame is not only strong, but greatly lowers its operating weight, increasing its portability to and around site. Its main handle can be folded for easy transportation and storage too. It is also equipped with a folding kickstand for added operator convenience. It additionally features a patented mount retention method which enables use of low durometer isolators without loss of operator control, whilst significantly lowering operator exposed vibration levels.
