1. The guardrail is pre-installed with the host mechanical system. The compact design of the handrail drive system reduces the escalator size and more effectively utilizes the building space. 2. The utilization of the new drive technology and the intellectual control system makes the running of Canny escalator more energy-saving and environment-friendly. The optional automatic stopping and running mode is more energy-saving because of the reduction of the running period. The optional intellectual variable frequency technology (VVVF) and ECO usually saves 60% of the energy on occasion of scarce flow of people. 3. Its superior design and integrated spare parts can more flexibly conform with the needs from both the commercial and public traffic and transportation. 4. The design of the guardrail with the handrail fixes the whole operation in the guardrail. It controls the move and avoids the friction amid the step, skirt panel and the comb. It brings the greater convenience to the installation, debugging, repair and maintenance. It lifts up the running effects.
