1. elevator, comprising:

  • The not elevator cage with counterweight;

    Be positioned at multiple the first deflection sheavies on described elevator cage;

    Be positioned at multiple the second deflection sheavies on described elevator cage;

    The ropes being formed by single rope or some parallel ropes;

    Be arranged on the traction sheave of the primary importance fixing with respect to the lift well of described elevator;

    Comprise the charging system of Part I and Part II;

    Wherein said elevator cage is suspended in described ropes by multiple the first and second deflection sheavies,Wherein said traction sheave utilizes described ropes to move described elevator cage,The first end of wherein said ropes and the second end are operably connected to described charging system,Wherein said ropes has the rope part up from described the first deflection sheave,Wherein said ropes has the rope part descending from described the second deflection sheave,Wherein be subject to the first rope pull from the up rope part of described the first deflection sheave,Wherein be subject to the second rope pull from the descending rope part of described the second deflection sheave,The Part I of wherein said charging system is arranged on the second place fixing with respect to the lift well of described elevator,Wherein, in the time that described elevator cage moves up or down, the Part II of described charging system moves with respect to the Part I of described charging system;

    Wherein said charging system acts in described ropes, thereby in described ropes, apply one or more balance pulling force, compensate the pulling force in described ropes, the elongation of ropes described in balance, compensate the elongation of described ropes, and keep the ratio substantial constant of described the first rope pull and described the second rope pullWherein said charging system further comprises damping, locking or damping and locks the equipment of described charging system;

    Wherein in the situation that occurring to accelerate, the speed of charging system, or more than acceleration/accel and speed is elevated to predetermined limit value, described equipment obstruction or stop the operation of described charging system;

    Wherein in described charging system, arrange the application force except the first rope pull and the second rope pull, andDescribed application force acts on and the first rope pull (T substantially 1) in identical direction.
