laser screed
Product Description
A Laser Screed is a high-precision concrete leveling machine designed to achieve flat and level concrete surfaces with superior accuracy and efficiency. By integrating laser control technology, hydraulic power, and mechanical leveling systems, it ensures precise elevation control and uniform surface finish across large floor areas.
This equipment is widely used in industrial floors, warehouses, parking lots, airports, and other large-scale concrete projects where surface flatness and smoothness are critical.
The laser screed automatically adjusts the leveling head height through laser receivers and a control system, significantly reducing manual labor and improving productivity. Compared to traditional methods, it shortens construction time, reduces material waste, and enhances concrete surface quality and overall flatness.
Working Principle
The Laser Screed operates based on a laser-guided leveling system that ensures precise concrete surface flatness. A laser transmitter emits a continuous reference plane across the working area, which is detected by laser receivers mounted on the leveling head. The control system interprets these signals and automatically adjusts the height of the screed head through a hydraulic servo mechanism.
During operation, the machine spreads, vibrates, and levels freshly poured concrete simultaneously. The vibrating beam compacts the concrete while the screed head cuts and levels the surface to the desired elevation. Real-time laser feedback guarantees that every section of the floor remains within tight tolerance limits, regardless of ground irregularities.
By combining automatic laser control, mechanical leveling, and hydraulic actuation, the Laser Screed achieves faster construction speed, higher flatness (FF/FL), and superior surface finish compared to manual or traditional methods.
