1、新的或長期停用的的電機，使用前應檢查繞組間和繞組對地絕緣電阻，并應在電機冷卻狀態下測量。
Should be checked before new or long-term disabled motor Hangzhou lifting platform, using inter-winding and winding insulation resistance, and should be measured at the motor cooling state.

2、檢查廠房升降平臺的電機的外表有無裂紋，各緊固螺釘及零件是否齊全，電機的固定情況是否良好及電機傳動機構的工作是否可靠。
Check the appearance of the motor plant in Hangzhou lifting platform for cracks, the fastening screws and parts are complete, fixed the motor is good and the motor drive mechanism work is reliable.

3、根據銘牌所示數據，如電壓、功率、頻率、聯結、轉速等與電源、負載比較是否相符，升降平臺電機的通風情況及軸承潤滑情況是否正常。
According to the data shown in the nameplate, such as voltage, power, frequency, link, speed and power, such as the load is relatively consistent, ventilation and bearing lubrication Hangzhou lifting platform motor is normal.

4、扳動廠房升降平臺電機轉軸，檢查轉子能否自由轉動，舉刷機構是否靈活，舉刷手柄的位置是否正確及電機接地裝置是否可靠。
Hangzhou plant lifting platform pulled the motor shaft and check the rotor can rotate freely, move the brush mechanism is flexible, move the brush handle is correctly positioned and electrical grounding device is reliable.
