Used Car lifts for sale

United Elevator

     Carry on the US innovation spirit,Possessing the German superior quality

     Two into one,which forges UNITED,Innovation,Change,Elaborate,Quality

     Only for your safe reach

Take safety and quality as mission

1.Stable and reliable protection device

(1)New generation landing door device

    United elevator firstly apply the new generation landing door device in the indurstry.Which prevent safety lock from slippery,landing door  bump,landing door unusual opening.The three new safety standards redefine the safety.

(2)Three dimensional infraed protector

    Form curtain at the door of elevator,194 infrared beams protection

    Make sensible response to any person or thing entering into detection scope with high level of safety performance.

(3)Emergent parking device

    When passengers are trapped in elevator due to power off,the device will automatically switch to emergent operation

    Make elevator leveling and open automatically through battery and release trapped passengers.

(4)Safety supervision system in elevator

    Each maintenance service network station of United Elevator makes real-time supervision over elevator in operation through reserved intelligent system interface(remote supervision interface);exclude malfunction before occurrence to guarantee 24-hour and 365-day safe and reliable operation of elevator.

2.Highly efficient control system

(1)New generation of advanced control system

    32-bit industrial ARM controller with high level of performance;precise speed signal with outstanding comfort;Combine all digital vectors inverter,make self-diagnosis and record through feedback to ensure efficiecy and safety of elevator;Perfect safety protection measures,be able to find emergencies and make corresponding protective measures when there is emergency arising to ensure safe and reliable operation;Strong anti-electromagnetic interference ability,strong antistatic electricity ability.

(2)Digital converter technology

    Make adjustment over current and phase according to practical load and speed of lift car,Make real-time and precise control over driving force of main machine to ensure safe and stable elevator operation.

           Long service                                          Rapid staring speed                                     Precise and stable operation

3.Intelligent passenger experience

(1)Intelligent management system

    IC card intelligent identification system;function to set authority management;realize perfect combination between elevator control technology and computer communication technology,reinforcing greatly safety and intelligence of building management.

(2)Group control intelligent dispatching system

    Adopt annular netword topology structure,make each system as independent main control cabinet to make signal deployment;make rapid calculation about optimal elevator operation pattern added with gene algorithm,relieving effectively heavy load in peak time of office building.

4.Energy saving environmental protection

(1)Permanent magnetic synchronous gearless machine system

    Low heat loss,low operation cost,working efficiency reaches as high as 95%,save 40% energy compared with general traditional technology,at the lve thoroughly environmental pollution resulted from oil leak of traditional tractor,reaching free of maintenance and environmental protection of electric machine.

(2)Energy feedback device

    Collect and store electric energy of no-load operation of elevator and then make feedback to elevator(electric mode)for use,saving more than 60% energy for elevator.

(2)LED automatic illumination system

    Adopt LED lamp,saving more than 85% energy compared with traditional incandescent light bulb and flourescent lamp;at the meantime,after certain period with no call and waiting command,the illumination inside lift car will be automatically turned off,reaching the purpose of energy conservation

5.Lightening speed to arrive

(1)The idea of speed

    Networks serial communication control system realizes detailed data exchange control,disperse processing with pertinence,improving response speed of elevator,guaranteeing highly-efficiency operation of elevator.

    New generation of control system of microcomputer with greatly increasing coputing speed of CPU,ensuring high efficiency and precision of system control.

(2)The idea of stability

    New lift car structure;add design of up and down fairing to reduce windage and improve comfort;

    Novel cushion technique,floating connection of lift car to reduce vibration of building and improve stability and comfort greatly of operation.
