Ligchine ScreedSaver Boss 240

The worlds largest boom operated screed

Ligchine re-invented the mega sized screed machine in 2016 when it introduced the feature loaded ScreedSaver BOSS 240 machine.  Not only is this the BOSS 240 the world’s largest boom operated screed it includes a Zero turn drive system.

We attach our standard 13.5’ (4.12m) screed head to a boom that reaches 18’ (5.5m) which means you cover 240 sq. ft./pass (22.3m2)  resulting in screed rates up to 10,000 sq. ft./hour (929m2) or more depending upon site variables. Screed accuracy (FF/FL) is world class!

· Our automated concrete additive spray bar system integrated into the screed head
