Lifting
!
CAUTION
The operator’s built-in lifting lugs/eyes are designed with the capacity to lift the GVO
operator and the pedestal. Additional lifting support is required to lift the operator
with a valve attached. Always use an appropriately rated crane/hoist and appropriate
straps/chains when raising and lowering the operator.
Vertical Lifting:
Before lifting the operator, make sure that the valve has been disconnected from the
operator. When handling and installing the operator, care must be taken, especially during
rigging and lifting the operator. The operator should only be lifted from the lifting lugs
located on the end cap, shown in Figure 5.
NOTE:
Operators should be lifted with force acting as vertically as possible. Spreader bars or other
lifting aids may be required to maintain a vertical lift on the lugs or eyebolts. Always lift the
operator with a 60° or greater lifting angle measured from the horizontal plane.
