We introduce a full set of the latest German control technology and apply new modern materials and the latest processing craft& technique to produce GRO20 serial observation lift products. This kind of products have the most perfect performance in lots of aspects such as the travel quality,safety functions, car model design,energy-saving and loss reduction etc.

We strive to bring an advanced super view aesthetics to the serial goods.Our products will be the most glaring flowing scene which up and down in the buildings.When the nigh falls,the lift deducts the dazzling light of aristocracy in the constructions.
These serial products are applicable for the high grade business hotel,office building,airport,bus station and other public transport places which require the sightseeing purposes.
More security in heart
We utilize the advanced and fully computerized modular variable voltage and variable frequency (VVVF) control system and handle the top control technology in the world.We comprehensively enhance the travel efficiency of the system through overall safety considerations and elaborately humanized design. Serial communication network results in the more concise and effective lift running.SMT (surface mount technology) reduces the print-board area and greatly strengthens the reliability of the electronic circuit.
VVVF door operator system
We apply the advanced VVVF variable volage and variable frequency control technology on door operation system as as to keep door running smoothly and switch quietly,automatically adjust the most appropriate open/shut speed in every floor so as to guarantee the fine security and reliability.Wheat is more, the self-tuning door load detector increases the sensitivity of the lift door switch.It monitors the variation of lift door load in every floor.When it encounters any abnormal resistance, the lift door load in every floor.When it encounters any abnormal resistance, the lift door will be automatically re-opened. The passengers enjoy wonderfully in the lift door open and shut.
Group control managing system
Group control managing system is that multi same model lift groups are controlled in use, the lift groups can automatically choose the most appropriate response. It avoids the repeated lift parking, reduces the passengers' waiting time and increased the travel efficiency.
