    • A balanced actuator device for lifting and transporting apparatus comprises a bearing frame (3), means (4) for supporting an external load (L), substantially vertical guide means (5) associated with said frame (3) to guide said support means (4), drive means (6) operating on said support means (4) to move them along said guide means (5) by a predetermined stroke (c) between a lower end position (A) and a upper end position (B). The drive means (6) include at least one preloaded elastic actuator element (7) which is designed to exert a sufficient balancing force (F) on said support means (4) to at least partially balance the load (L) thereby allowing minimization of the size of the drive means (6).
    • 一种用于提升和运输设备的平衡致动器装置,包括一个支承框架(3),用于支承外部负荷(L)的装置(4),与所述框架(3)相关联的基本垂直的导向装置(5) 在所述支撑装置(4)上操作的驱动装置(6)沿着所述导向装置(5)在下端位置(A)和上端位置(B)之间移动预定行程(c)。 驱动装置(6)包括至少一个预加载的弹性致动器元件(7),其被设计为在所述支撑装置(4)上施加足够的平衡力(F)以至少部分平衡负载(L),从而允许最小化 驱动装置(6)的尺寸。
