谁能帮我把下面的这段英语翻译了啊 拜托!要能读的通顺啊 不是百度翻译就行了啊
Due to the converter weight, postures used, and difficulty in installing the converter, a lifting aid was evaluated in a user trial conducted as part of the 1990 study. The aid was a ceiling-mounted balancing hoist that utilized a vacuum cup to hold the converters. In the user trial, the worker aligned the vacuum cup with the center of the torque converter, actuated the vacuum, and lifted the converter from the rack. The worker stepped back to clear the rack, turned the arm 1803, and aligned the converter with the transmission housing (Fig. 1). At this point, the balance arm was pushed forward until the converter contacted the splines on the output shaft, and was then rotated about the longitudinal axis and pushed simultaneously to engage the converter on the splines.
