Overview
JSTY5070KTE is a pure-electric mobile passenger boarding stair designed for airport ground operations. Based on the Qingling EV100 electric class II chassis (QL1070BEVECHA2Y), the unit provides a wide lifting range and capacity for up to 88 passengers. Main components use established-brand parts (VCU02 vehicle controller, YTD060W23 drive motor, KTZ50X35S motor controller), delivering compatibility with domestic aircraft types and compliance with current ground handling requirements.
