CN Automatic lifting partitions is a new type of automatic partition product developed by CN company on summing up the advantages of similar products at home and abroad and integrating the characteristics of our own products. Use high efficient and energy saving SEW motor from Germany with high torque as the main equipment, the partition running smoothly without any dithering and halt. Our automatic lifting partition have beautiful appearance, fashion color and reliable performance. Adopt advanced intelligent control system and vector control frequency converting technology, can control the speed and output torque precisely, make the partition wall run smoothly and steady. We choose the key parts imported from Europe and use the high strength aluminum alloy framework to ensure the best running status. Use the unique electrostatic balance technology to form a closed tight, dust-proof, excellent anti static brush closed system. 

3. Quality control of iron parts

All specification and dimension and quality of hot galvanizing steel must meet the design requirements. Sampling inspection must be carried on to report to the quality inspection department.

4. Quality control of hardware accessories

Hardware accessories including a variety of stainless steel bolts, nuts, door handle, springs, locks and so on. Approved product standard and quality certificate must be provided by the supplier. The professional quality inspector approve whether the accessories meet the technical requirements and report to the quality control department. The chemical composition and mechanical properties of stainless steel bolt must be sampled.

5. Quality control of structural adhesives and weather proofing silicone sealant

The compatibility test report must be provided when structural adhesives and weather proofing silicone sealant be used and reported to quality control department after acceptance. The following points must be noted:

Parts list of automatic lifting partition wall

Safety system

Adopt slow down system from Germany ensure the maximum safety when the system is in use. When the falling speed is too fast, slow down system will be started automatically to prevent the partition wall from falling rapidly. The system adopts an optimized intelligent anti-collision design. The door panel can be equipped with an electric eye or a collision switch to realize anti-collision protection (for customers to choose). When there is an obstacle under the lifting partition detected, the lifting partition will automatically stop and brake lock, after clearing the obstacle will run automatically. Equipped with key switch to prevent non-management personnel to operate the system. 

The control system can also be linked with the fire control system and the intelligent building system. When receiving the fire signal, it can be automatically raised and cut off, allowing people to evacuate.
