It can carry up to 2000kg and can accommodate various beds. With advanced technology and intimate design, power outage emergency rescue device, Internet of Things and other configurations are optional, perfect for transporting doctors and patients, beds, medical equipment, etc., suitable for hospitals, sanatoriums, emergency rescue centers, medical institutions and other places. Using the latest generation of permanent magnet synchronous technology, with high energy saving, high environmental protection and high efficiency and low noise characteristics, Effectively achieve the goal of energy saving, electricity saving and installation cost saving, and set off a storm of energy conservation and environmental protection for the energy-saving era of the 21st century. Using the world's most advanced energy regeneration theory, energy feedback principle based on dual PWM control, The potential energy in the elevator operation is converted into electric energy and returned to the power system of the building, which reduces the harmonic pollution of the power supply and realizes the renewable utilization of energy.
