Passenger boarding ladder (heightened) is a new type of pure electric airport ground equipment designed and manufactured by Tianyi Joint Stock Company for passengers to board and disembark from aircraft, with the external dimensions of 2340mm x 3600mm and the platform height of 2200-5800mm, which mainly consists of QINGZHUO electric drive chassis, fixed ladder and sliding ladder, docking platform, hydraulic system, electric system and so on, and the whole vehicle adopts the mature and reliable power system. With strong climbing ability and good low-speed stability, it can meet the current domestic ARJ21, ERJ190, B737CL, 737NG, 737MAX, A320 series, A320NEO and other aircraft models.
The chassis adopts Qingling commercial chassis, the cab is equipped with heating and cooling air-conditioning system, all kinds of instruments and switches are complete, frequency conversion stepless speed regulation, equipped with Shanghai Automotive Electric Drive Co. R16 14PR tyres.
Adopting Ningde Times lithium iron phosphate battery with the first domestic market share, mainly composed of battery module, battery management system, thermal management system, cooling system and other parts.
With explosion-proof fire extinguishing system and BMS power management system, the normal charging and discharging times of the power battery are not less than 4000 times under normal temperature (ambient temperature 25℃), and the normal charging and discharging times of the power battery are not less than 4000 times under normal temperature.
4000 times, and in the normal charging and discharging 4000 times, its storage energy is not less than 80% of the designed storage energy, using 90kw charging pile from the low battery warning level to full charging time is not more than 1.5 hours, and the charging time is not more than 1.5 hours.
The charging time from the low battery warning level to full charging of 90kw charging pile is not more than 1.5 hours, equipped with national standard charging interface, meeting the all-weather charging requirements of civil airport apron conditions.
