沿前后方向延展且经过上轿底1的上端面中心同时垂直于上轿底1的上端面中心的面为中心面，电梯轿底关于中心面对称。The plane extending in the front-rear direction and passing through the center of the upper end surface of the upper car bottom 1 while being perpendicular to the center of the upper end surface of the upper car bottom 1 is the center plane, and the elevator car bottom is symmetrical about the center plane.

综上：1.上轿底采用超薄设计，用矩形管做筋保证轿底强度并且充分压缩底坑空间；2.轿门地坎托板采用对称设计，实现旁开门时通用；3.采用优质减震橡胶，乘坐更加舒适；4.托架采用厚板C型折弯嵌装焊接，结构牢固可靠；5.轿底防倾支架与F型橡胶夹有效的防止轿底倾覆；6.非门区侧用可调式配重块调节轿厢的静平衡，使电梯运行更加平稳。7.配以下行超速保护机构，保证了电梯乘客的安全。To sum up: 1. The upper car bottom adopts an ultra-thin design, and rectangular tubes are used as ribs to ensure the strength of the car bottom and fully compress the pit space; 2. The car door sill support plate adopts a symmetrical design to achieve universal use when the side door is opened; 3. The use of High-quality shock-absorbing rubber, more comfortable to ride; 4. The bracket is welded by thick plate C-shaped bending, and the structure is firm and reliable; An adjustable counterweight is used on the side of the door area to adjust the static balance of the car, so that the elevator runs more smoothly. 7. Equipped with downlink overspeed protection mechanism to ensure the safety of elevator passengers.
