1. Laser gun is installed separately,which makes 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 joint place,thus lower the follow-up ground maintenance cost.

2. Integrated leveling head comprises scraper blade,vibrator,vibrating plate,screw conveyor and other parts,combining working procedures of mixing,leveling,vibrating and etc. To complete the job in a row,so as to increase efficiency and reduce cost.It can keep level of the working surface even when the ground base is uneven with bumps and slope.Square and vibrating plate of 4000 times/min high vibration frequency will ensure concrete floors with great intensity and dispersed deformation strength ,thus effectively prevent the occurrence of floor bubble,shell,cracking and unevenness.

3. The elevation is measured automatically by the laser measurement and conctrol system;and the ground is high point height is automatically controlled by the laser machines" computer. Based on that, the ground can be more even by precision leveling directly on the concrete layer and the ground flatness will not be infuenced by the pattern plates. Without having to do the formwork,the cost for material and labor as well as the working period will all get reduced. This machine can finish construction areas of more than 300 sq.meteistic centers,conference and exhibition centers ,etc.
