An elevator car (2, 2 ') comprising: a first safety brake (8, 8') comprising a first electronic safety actuator (512, 612) wherein the first safety brake (8, 8 ') is positioned on a first side of the elevator car (2, 2') at a first height (20, 20 '); and a second safety brake (10, 10 ') comprising a second electronic safety actuator (512, 612) wherein the second safety brake (10, 10') is positioned on a second side of the elevator car (2, 2 ') at a second height (22, 22'); wherein the first height is different from the second height. By providing two safety brakes each comprising an electronic safety actuator, it is possible for the brakes to actuate together (i.e., synchronize) without the need for any mechanical linkage between the two safety brakes. Because no mechanical linkage is required, the safety brake does not need to be positioned at the top or bottom of the elevator car (i.e., above or below the cabin). This allows the safety devices to be positioned at a greater range of heights on the elevator car as they are not limited to be positioned only at the top or bottom of the elevator car. Further, positioning each of the safety brakes at a different (i.e., asymmetric) height gives greater versatility and convenience to other design factors.
一种电梯轿厢(2、2'),包括:第一安全制动器(8、8'),包括第一电子安全促动器(512、612),其中,第一安全制动器(8、8')定位在电梯轿厢(2、2')的第一侧上在第一高度(20、20')处;以及第二安全制动器(10、10'),包括第二电子安全促动器(512、612),其中,第二安全制动器(10、10')定位在电梯轿厢(2、2')的第二侧上在第二高度(22、22')处;其中,第一高度不同于第二高度。通过提供均包括电子安全促动器的两个安全制动器,对于制动器来说可能一起促动(即,同步),而不需要两个安全制动器之间的任何机械联动装置。因为不需要机械联动装置,安全制动器不再需要定位在电梯轿厢的顶部或底部处(即,在舱室上方或下方)。这允许安全装置定位在电梯轿厢上更大范围的高度处,因为它们不限于仅定位在电梯轿厢的顶部或底部处。此外,使安全制动器中的每个定位在不同的(即,非对称的)高度处为其它设计因素给予更大的通用性和便利性。
