Newly introduced Locking Unit, FLAT&LOCK AEZF series




The parking space ground with our old model of locking device has not been flat because of its locking flap board and big cover, which has been some annoyance for drivers when cars go in and out of the spaces. Moreover, these devices caused the parking spaces to be smaller.


However, our newly introducing FLAT&LOCK AEZF series has no locking flap board and big cover, which enabled the parking spaces to be bigger. This new FLAT&LOCK AEZF provides drivers with easier and safer parking.


As this device is universally designed, we have received positive feedbacks such as “very helpful for wheelchair users or users wearing high heels”. Openings of unmanned parking lots with AEZF series are now increasing.

1. This FLAT&LOCK is suitable for parking lots of universal-design because it has no level difference and big covers.

2. The risks of damaging car parts by thrusting locking devices are reduced because the lifting power of locking unit can be arbitrary adjusted.

3. Lowered locking device is designed to become flat to the ground so that drivers and other users’ feet do not get caught in the device.

4. The Device Locking System, the function to prevent the lifted device from being pushed down manually, prevents cars from leaving without paying fee.

5. Emergency Unlock Function allows parking lots owners and servicemen to lower the locking device in case of troubles such as blackout.
