3.4.1 Motor Lifting Provisions
The EC Titanium motors provided in 180 and 210 frames are provided with lifting provisions. Always lift the motor by the
lifting bolt eye or lugs provided. 140 Frame Motors do not require lifting provisions and can be set in place manually. (2)
Lifting Lugs are provided on Top Drive Units that are offset to balance the motor weight as shown below in Figure 3-1.
Caution: Do not lift the motor and its driven load by the motor lifting hardware. The motor lifting hardware is
adequate for lifting only the motor. Disconnect the driven load from the motor shaft before lifting the
motor.
Caution: Do not lift the motor by the shaft. The motor is designed to drive a load but it is not intended to have
lifting forces and stresses applied to the motor shaft. Damage to the motor may result
Caution: If eye bolts are used for lifting a motor, be sure they are securely tightened. The lifting direction should
not exceed a 20° angle from the shank of the eye bolt or lifting lug. Excessive lifting angles can cause
damage.
