EQUIPMENT FEATURE CONTINUED Vibrations from a motor attached to the truss carry throughout the screed as contractors guide it on concrete forms, flattening and settling the concrete to remove trapped air, increase concrete strength and provide a
Born with a long reach and a wide pass, the Ligchine SCREEDSAVER ULTRA PLUS was built to screed more and screed faster.

smooth finish. However, due to the vibration, it is generally not recommended to utilize a truss screed on a slope. The aggregate in concrete
tends to settle with vibration and unevenly dispersed aggregate can create spots of varying strengths that can result in structural flaws and damage over time. Truss screeds can be powered by an engine or air, with the latter preferred for indoor jobs or tunnels when a combustible engine would be prohibitive. Giving contractors the ability to expand the truss and screed blade needed for the project, it’s common for truss screeds to come in sections of various lengths. Additional sections can be added to achieve a maximum width and some models may have limits. Best practices suggest selecting a screed width that allows a minimum of a 6-in. overhang past your concrete form.
