At Perodua’s Bumper Shop, we had to change 4 shutter doors for two sets of lifter system. Before this upgrade, production was using manual shutter door system which raised few safety counter measurements. GTG upgrades this system by changing the manual steel door to automatic PVC Cloth door which is way convenient and ergonomically safe for human interaction. In addition, a new control panel were also installed which also enhances the safety measurements which enables not to open the shutter when there is no lift detected on that specific floors. In a nutshell, this upgrade has a anti-bypass system which controlled by the servo motor encoder switch thus, making it more safer while interacting with the lift.
