○ The upper and lower holding devices are adopted to prevent the door from leaving its guide device and avoid the danger of falling into the well for human reasons.
○ Integrated car door lock, prevent falling into the well, to ensure the safety of passengers.

Comparison between traditional machine room-less and RICH-MRL top landing

○ Top floor civil engineering need no host beam reserved holes, also do not need to care about the hole position and support force;
○ Drive structure is installed on the top of the guide rail, transfer the system force to solid ground of the pit
○ The structure is more compact, the top landing work space is larger;
○ The quality of the drive system is greatly reduced, the installation time is reduced by 30%, and the installation is more convenient.

Small machine room elevator
Innovatively Designed Machine-Roomless Elevator
Exquisite and small drive layout scheme

○ Excellent brake misoperation monitoring system ensure passenger safety.
The unique intelligent thermal monitoring and feedback system of the driving machine ensures the reliable operation of the traction system.

Wireless Network-based Remote System Management and monitoring Platform (Elevator Internet of Things)

○ The Internet of Things system monitors the elevator operation 24 hours a day.
○ Early warning and active notice can effectively prevent elevator accidents.

Energy Feedback Technology (optional)

Energy feedback: green, environmental protection, health
With the growing scale of the city, there are more and more high-rise buildings in the city. While bringing people convenient and comfortable life, the elevator consumes a lot of energy. In order to meet the new trend of environmental protection, the revolutionary energy-saving technology of elevator - elevator energy feedback technology came into being.

The principle

Energy feedback unit, by automatically detecting dc bus voltage of the inverter, the DC voltage of the DC link of the inverter is inverted into the AC voltage with the same frequency and phase as the power grid voltage , after multiple noise filter is connected to ac power grid, so as to achieve the purpose of energy feedback power grid, feedback to the electricity grid reached more than 97% of the electricity energy, effectively saving the electricity.

Energy feedback benefits

○ Energy saving, green environmental protection
The energy feedback system converts the electric energy generated under the state of power generation operation into clean and pollution-free electric energy to feed back to the power grid, which can further save up to 30% energy compared with the elevator without energy feedback function.

○ Prolong the service life of components
Due to the cancellation of the regenerative resistance of the elevator, the temperature in the machine room decreases, thus effectively extending the service life of equipment components.

○ Save the input of heat dissipation equipment in the machine room
As the temperature of the machine room decreases, the capacity of the equipment for heat dissipation in the machine room decreases significantly, saving the customer a lot of equipment investment and electricity costs.

○ Renewable energy is filtered by high-performance EMI
The renewable energy of the energy regeneration module is filtered by special high-performance EMI filter to eliminate harmonic interference and avoid interference to other equipment in the power grid.

○ A truly comprehensive energy feedback system
The module can not only save energy in the regenerative state, but also play a role in the motor energy consumption state, it can greatly reduce noise and vibration, and thus improve the comfort of the ride ladder.
