1.Intelligent operation by the handle and easy to control; one person can operate the laser screed machine. It can freely move and turn with agility, allowing a running system controlled by hand. The wheels can go forwards, backwards and around with manually controlled speed.

2.Laser gun is installed separately, making it possible to do large area one-time construction while ensuring consistent ground level. The ground level will not be affected by the pattern plates, inducing no random error. Large area one-time construction will reduce the joint place, thus lower the follow-up ground maintenance cost.
3.Integrated Leveling Head comprises scraper blade, vibrator, vibrating plate, screw conveyor and other parts, combining working procedures of mixing, levelling, vibrating, etc., to complete the job in a row, to increase efficiency and reduce cost. It can keep the working surface level even when the ground base is uneven with bumps and slope. Square end vibrating plate of 4000 times/min high vibration frequency will ensure concrete floors with great intensity and dispersed deformation strength, thus effectively preventing floor bubble, shell, cracking and unevenness.
4.The elevation is measured automatically by the laser measurement and control system, and the laser machine’s computer automatically controls the ground’s high point height. The floor can be more even by precision levelling directly on the concrete layer, and the pattern plates will not influence the ground flatness. Without being the formwork, the cost for material and labour as the working period will all get reduced. This machine can finish a construction area of more than 300 sq. meters per hour. which means 3000-5000㎡ per day.
