重慶升降機發動機磨損尺寸在前后兩缸的上部，應重點測量這兩缸。氣缸套的磨損情況通常用量缸表測量，量缸表就是普通的內徑百分表。

1、根據貨梯磨損前的缸徑尺寸選擇合適的接桿，在接桿上擰上固定螺母，將其擰入量缸表下端，將量缸表的測桿插入氣缸套上部進行測量。
According to Hangzhou freight bore size selection before abrasion suitable extension rods, screw on the connection rod retaining nut, which is screwed into the cylinder form the lower amount, the amount of the cylinder rod inserted into the cylinder sleeve section table of measurements.

2、為了保證貨梯測量的準確性，需在缸套內孔壁的上、中、下三個位置進行測量。上部位置是活塞在上止點時，第一道活塞環與缸壁接觸部位；中部位置是在缸套的中部；下部位置是活塞處于下止點時，下面一道油環所對應的缸壁位置。
In order to ensure the accuracy of Hangzhou freight measurement need to be measured on the cylinder liner bore wall, the next three positions. The upper position is at the top dead center, the first piston ring and cylinder wall contact area of the piston; the central location is in the middle of the cylinder liner; the lower position of the piston is at bottom dead center, following a oil ring position corresponding to the cylinder wall .

3、將重慶升降機量缸表在磨損最大部位的橫斷面上轉動90°測量，此時表針所指數值，即為圓度誤差值，將內徑百分表上下移動到一定位置測量，可測得氣缸的圓柱度。
Hangzhou freight volume will rotate 90 ° cylinder table wear measurements on the largest part of the cross section, then hands the value referred to, is the circularity error value, will move to a certain position up and down the inside diameter dial indicator measuring cylinder can be measured cylindrical degrees.
