Aolida has over 20 years of experience in the development of freight elevators, and has developed a multi gantry anti large eccentric load bearing car structure and a matching 4:1 traction method. It adopts a mature CS5000 variable frequency drive control system,
Comprehensively improve the performance of elevator operation. Successfully developed a traction type heavy-duty freight elevator with a load capacity of 40000 kg, becoming the first domestic elevator enterprise with the qualification to manufacture a 40 ton heavy-duty freight elevator.

This type of elevator has a rated load capacity of 3000Kg and a running speed of 1.0m/s. It adopts a permanent magnet synchronous gearless traction machine with a compact structure, efficient transportation, improved high-altitude utilization, reduced energy consumption, and meets the aesthetic and design requirements of various buildings.

The ultra high speed elevator is the direction of technological development in the elevator industry. The main indicator parameters independently designed and manufactured by Aolida are a speed of 8m/s and a load capacity of 2000kg. The ultra high speed elevator with a large load capacity has been installed and successfully operated in the test tower. All operating indicators have been strictly tested by the National Elevator Quality Supervision and Inspection Center, fully reaching the industry's advanced level.

DI is the abbreviation of the German Institute of Engineers (responsible for standard development and distribution within Germany), and VDI4707 Part 1 is a standard specifically designed for elevator energy efficiency. According to the different energy requirements for elevator operation and standby in different situations, the energy consumption standards are divided into seven levels, A-G. Aolida has obtained A-level certification for elevator energy consumption.

Energy feedback is the trend and direction of elevator energy-saving technology development. By fully utilizing the IGBT power module, the characteristic of bidirectional energy flow can be achieved. The frequency converter with PWM control rectifier has the function of four quadrant operation, which can meet the speed regulation requirements of various potential loads and the energy conversion requirements of various working conditions. It is a true "green" frequency converter.

This type of elevator adopts mature elevator technology, combined with equipment cleaning treatment technology. The elevator car has a certain level of air cleanliness and has sterilization function; Mainly used in highly precise dust-free (sterile) environments such as hospitals, pharmaceutical factories, computer chip workshops, instrument laboratories, spray painting workshops, and semiconductor electronics, biochemical and pharmaceutical industries.
