2 General Handling Procedures for Medium Voltage Controllers
MV-QS050B-EN-P – November 2006
Using a Fork Lift
A fork lift is the most common and versatile method for moving a
single controller.
1. Insert forks into openings located at the front of the skid.
2. Carefully balance the controller on the forks. Depending upon the
options installed, the center of gravity may be offset.
3. Use safety strap(s) to ensure the controller remains steady.
Overhead Lifting
When two or more controllers are shipped as an assembly, overhead
lifting is the recommended method for safely moving it in your facility.
1. Attach rigging to the lifting apparatus.
A T T E N T I O N A T T E N T I O N Ensure that the load ratings of the lifting device,
slings, hooks and shackles have a lifting capacity
rated equal to or greater than the load. Failure to
do so may result in personal injury and/or
equipment damage. For your controller’s
specific weight, refer to shipping weights on the
packing slip.
2. Do not pass slings or cables through the support holes in the
lifting angle brackets. Use slings with safety hooks or shackles.
3. Select or adjust the rigging lengths to compensate for the unequal
length and weight distribution of the load. Maintain the controller
in an upright position.
4. To reduce the tension of the rigging and the compressive load on
the lifting device, do not allow the angle between the lifting cables
to exceed 45 degrees from the vertical plane. (See Figure 1)
