Kinetix MMA Asynchronous Main Motors Installation Instructions
Instructions to Lift
Read these precautions before you lift the motor.
Eye hooks and lifting holes are installed for the handling and installation of the motor.
depicts the location of the attachment points. It is permissible to use the
flange or foot mounting holes to attach lifting lugs.
Figure 5 - Lift Attachment Locations
Before lifting, verify that the lifting lugs are secure, that the load is balanced, and that the cables and the lifting system are rated for the motor weight. Different lifting
scenarios are needed based on the orientation of the shaft and the weight of the motor.
The lifting holes are sized for the motor weight. Do not use these lifting holes to lift other components or machine parts (for example: gearboxes or platforms) that are
connected to the motor. Adjust the rigging lengths to compensate for any unequal weight distribution of the load. A hoist or crane, spreader bar, straps, and J-hooks with a
lockable clasp capable of supporting the maximum motor weight are recommended.
ATTENTION:
All equipment and hardware that is used to lift the motor must be properly sized and rated to lift and
safely hold the weight of the motor. To guard against possible personal injury or equipment damage:
• Inspect all hardware for proper attachment and use all eye hooks or lifting lugs.
• Eye hooks can unscrew during a lift. Before the lift, check the eye hooks to verify that they are tight. Attach the lift
equipment to restrict movement during the lift, alternatively, lift the unit on a platform or with a sling.
• Eye hooks or lift lugs are intended to lift only the factory-produced motor and accessories.
• Do not mount additional equipment before the lift or before the motor is secured.
• Do not let any part of the motor or lift equipment contact electrically charged conductors or components.
• Do not subject the motor to high rates of acceleration, deceleration, or shock forces caused by abrupt raising,
lowering, swinging, or twisting of a suspended motor during a lift.
• Help prevent personnel and their limbs from being in contact with the motor during a lift.
To attach lifting lugs to the rear mounting feet, remove the rear access panels.

ATTENTION:
When lifting and handling, follow all applicable local, national, and international codes, standards,
regulations, or industry guidelines for safe practices. When using the factory installed eye hooks, use both eye
hooks to lift. When using mounting holes, keep the load balanced and/or use all mounting holes. It is
recommended that an experienced rigger is employed.
