(1) the leveling principle of laser leveling machine, using precision laser technology, the closed loop control technology and high precision of the hydraulic system, under the automatic control of the computer, this is it different from other floor construction technology of the most prominent characteristics.

(2) the precision leveling principle of laser leveling machine is, rely on hydraulic drive the whole flat, together with the laser system and computer control system in the automatic leveling leveling work done at the same time. Equipped with integrated design on the whole flat scraper, vibrator, and the whole plate, put all the leveling, leveling, vibrating compaction working set at a suit, and one-time finish. Computer control system for real-time automatic adjustment of elevation 10 times per second, balanced design vibrator vibration frequency up to 3000 times/min.

(3) is used to control the ground elevation of laser transmitter is independent of, so, floor elevation is not controlled by the template, and won't produce cumulative error.

(4) laser leveling machine to control the longitudinal and transverse slope can be automatically, also is by a laser system, computer system, hydraulic system and mechanical system complete unity. Demanding complex shapes such as drainage of the ground, also optional 3 d alien ground processing system.
