Recently, reporters from the government procurement information newspaper/network interviewed Shen Jiangyuan, deputy manager of Lincoln Elevator (China) Co, LTD. According to his introduction, the core competitiveness and advantages of products of Lincoln elevator are mainly reflected in three core components – main engine, door operator and control cabinet, and four safety components, namely, safety tongs, speed governor, bumper and upward speed protection which are original brands and have intellectual property rights and patent technology. Next, Lincoln elevator will further enhance development force of the government procurement market, speed up shanty transformation projects, projects of affordable houses, and projects of hospitals and schools, reform old elevators and safeguard markets, and strive to enter into markets of installation of elevators in old buildings, public transportation and equipment with parking systems.

What are main advantages of products of Lincoln elevator? Shen Jiangyuan: seven core components 

Differences are mainly in high-end technology and brand influence

The government procurement information newspaper/network: what do you think are differences and advantages of domestic brand elevators when compared with elevators of foreign-funded or Sino-foreign joint brands?

Shen Jiangyuan: the advantage of domestic brands is high cost performance. At present, elevator parts have been in leading position in the world wide in technology and quality, especially for the medium and low speed elevators and escalators with a hoisting height of less than 10 meter, parts have basically realized domestication. And for medium and slow speed elevators and escalators with a smaller hoisting height, differences between domestic brand elevators and foreign-funded and Sino-foreign venture brand elevators are very small.

At present, the main demands of the Chinese elevator market are from common residence, affordable houses and infrastructure. And the demands are mainly on medium and slow speed elevators. Depending on high cost performance, domestic elevator brands have bigger market shares in the market, and moreover, domestic brands can provide more delicate after-sales services with their advantageous geographic position.

Compared with foreign-funded and joint brands, the biggest differences of domestic brands are mainly in high-end technology and brand influence. For example, core technologies such as tractors and computer group control devices of super high speed elevators and escalators with a high height are obtained by the few foreign-funded brand enterprises. In addition, to improve property values, some developers and purchasing units select international famous brand elevators. Since domestic brand elevator enterprises started later, have weak economic strength and management level, do not have sufficient input in research and development of new products, breakthrough of high-end technology and brand popularization, they have differences with foreign-funded and Sino-foreign joint enterprises, but the differences will become smaller with time passing by.

Innovate and develop ten safety systems

The government procurement information newspaper/network: what efforts Lincoln elevator have made in safe operation of elevators which is concerned by the society?

Shen Jiangyuan: at present, few safety accidents are reported by the media. Generally speaking, elevator accidents mainly have reasons in three aspects: the first is product quality and hidden risks in installation; the second is improper usage of users; and the third is improper maintenance in usage.

Lincoln elevator innovates and develops ten safety systems, namely, multi-plate safety brake, safety tongs, speed governor, screen door protection device, door protection, anti-pinch safety system, tractor star sealing technology, bumper, cabin accident mobile protection and upward speed protection, so as to make passengers feel stable and relax when taking elevators. Once there are failures, the safety system will guarantee safety of passengers.

In the aspect of security, we have more than practical new patents. The new control system used by Lincoln elevator has advanced elevator self-protection and self-investigation function so as to avoid hidden risks. When there are emergencies, the safety mode will be launched automatically. For example, the power cut emergency function and fire control function can guarantee safety of passengers and inform maintenance personnel of reasons in a direct and understandable way.

Lincoln elevator is equipped with remote monitoring system, and the control system is directly connected with main board of internet of things without adding external sensors and cables, and moreover, data will be more accurate and detailed. In addition, Lincoln elevator developed an APP for maintenance so as to provide convenience to parameter changes in site with a Bluetooth module which is in the same size with a USB. Our company has 28 detailed standards for installation of the products, including standard installation of core components and safety components, spatial space of cabin top, pit and machine room, and cleanness, power and circuit standard connection. Later, the company will assign personnel to adjust elevators to make them operate normally.

The three core components are main advantages of the products

The government procurement information newspaper/network: by taking products of Lincoln elevator as an example, what do you think are core competitiveness and advantages of them, and how will you further explore the government procurement market next?

Shen Jiangyuan: Lincoln elevator opens markets with high quality products and consolidates markets with high quality services.

In terms of products, the three core components of the Lincoln Elevator: “host”, “door machine” and “control cabinet”, four security components: “safety gear”, “speed limiter”, “buffer” and ” Speed ​​protection “are the original original brand, and has independent intellectual property rights and patented technology.

Meanwhile, we can realize the maximum speed of 10m/s and the maximum load of 5,000kg. Moreover, our main engine (tractor) adopts the independently developed disc brake and imported SKF bearing. Control cabin adopts the latest motor control technology and electronic technology; adopts elevator control and drive integration design to simplify internal design of control cabin, reduce connection lines and improve operational reliability; adopts direct current contractor; installs “energy feedback system” to make 98% renewable energy sources can be reused and make effective recovery rate reach to above 30%; and installs direct stop function to improve operational efficiency of elevators. In addition, elevators are equipped with remote monitoring system and height of door is 2,400mm when conditions permit. All elevators and equipment produced by Lincoln has bought “responsibility insurance of special equipment”

In the aspect of service, Lincoln elevator carries out point maintenance system to provide 24h all-round services.

At the next stage, Lincoln elevator will further enhance the development force in the government procurement market, speed up shanty transformation projects, projects of affordable houses, and projects of hospitals and schools, strive to reform old elevators and maintain markets, and enter into markets of installation of elevators in old buildings, public transportation and equipment of parking systems.
