From
time to time cement and lime plants have the need for special devices
to accomplish one-time or abnormal maintenance functions. The Satellite
Cooler Scaffolding pictured above is an example of one of those situations.
Problem:
The Satellite Cooler at Ash Grove Cement in Seattle, Washington was
being converted from castable lining to a brick lining. This required
the removal of castable anchors by burning off the fasteners from the
outside diameter of the cooler. Ash Grove needed a safe and efficient
way for workers to work on the cooler vessel while in place some three
stories above ground.
Solution:
In three days Bricking Solutions designed and delivered the scaffolding
pictured above to the plant. The scaffolding consisted of a semicircle
aluminum fixture with traveling ladders on either side of the cooler
tube. The fixture was hoisted by a mobile crane to the top of a cooler
tube and temporarily welded to the cooler tube. The workmen are then
tied off to the fixture and used the movable ladders to access the circumference
of the tube. This provided for a safe and efficient way to burn off
the fasteners holding the castable anchors.
Justification:
-
The use of the scaffolding increased the speed of the repair decreasing
outage time
-
Decreased the charge for the mobile crane because the work proceeded
faster
-
Reduced the labor cost for man hours needed to complete the job
