Laser Screeds are self-propelled four wheel drive, four wheel steer units with a telescoping boom for creating flatter and more level floors. The machine uses automatic laser control systems to ensure accurate level finishes through the use of electro-hydraulic controls.
Concrete is discharged in strips to match the size of the machine and the Laser Screed moves into position and the telescopic boom extended over the discharged concrete. The screeding head is then lowered to the grade established by the laser-level transmitter. Retraction of the boom causes the screed head to be drawn across the fresh concrete which is leveled and compacted in a single pass.
Once a pass is completed, the machine is repositioned to the right with some overlap on the previously screeded concrete. The operation is repeated, ensuring optimum finished level tolerances are attained across the whole floor area.
