"The highest escalator" of Badaling Great Wall Station of Beijing Zhangjiakou high speed railway made in Zhejiang

Zhejiang Online Beijing December 31 (Zhejiang Online reporter Tang Jun Maasai Jie) "made in Zhejiang" is on again - on December 30, when the Beijing Zhangjiakou high speed railway officially opened for operation, three ultra-high escalators with a vertical height of 42 meters and a length of 100 meters appeared at the Badaling Great Wall High Speed Railway station along the railway, which has set a new record of escalator height in the field of high-speed railway in China. It is understood that this group of super high escalators is independently designed, developed, manufactured and installed by Zhejiang enterprise Hangzhou Xiao Elevator Co., Ltd. (hereinafter referred to as "Xiao elevator"), which is another demonstration of the hard strength of "made in Zhejiang". On the same day of

, the reporter came to Badaling Great Wall high speed railway station for field visit. The station is one of the important transportation facilities for the 2022 Beijing Winter Olympic Games, with a maximum buried depth of more than 100 meters, known as the "deepest high-speed railway station in the world". The super high escalator is located at the exit, which can carry more than 400 people at the same time, with a transportation capacity of about 6000 people per hour. From the 42m underground, the reporter took the escalator for timing experience, and the escalator slowly reached the ground, sharing 3 minutes. According to the calculation of 2.9m storey height of conventional residence, 42m is equivalent to nearly 15 storey height. "The whole project is a major innovation." Shao Weifeng, director of elevator and escalator R & D Department of Xi'ao, said that the superhigh escalator has 12 independent innovation patent technologies, creating the number one in many domestic industries. For example, this group of escalators is the first to apply "breaking capacity of more than 30 kn" in the domestic industry, which means that the 15 kg first-class escalator "step" can withstand more than 3 tons of instantaneous impact force. The safety and reliability of

comes from ingenuity. "Because it's a means of transportation for people, we think most about the safety and reliability of elevators in the design, manufacturing, construction and other links." Wang Weiming, general manager of Beijing Branch of Xi'ao elevator, said that before the escalator was transported to Beijing Badaling Great Wall high speed railway station for installation, the company carried out 480 hours continuous trouble free operation test on all escalators in Hangzhou plant area to verify the reliability of the products. Moreover, more than 40 types of safety devices and 140 monitoring points are set on the escalator with a vertical height of 42 meters.
