13.11
Do not neglect the delivery pipeline, clamps, or hoses. Check
them often for wear, dents, and frays. Never send a unit to a job with a worn or
damaged delivery system. For single-wall pipes, ultrasonic thickness testers are
more accurate than the tap method (see Figure 69). Double-wall pipe are not
inspected in this way.
14. Safety Rules Regarding Scheduled Maintenance
14.1
Proper and timely maintenance is important to the safe opera-
tion of a concrete pump and placing boom. The proper procedures are outlined in
the operation manual supplied with the pump. Do not put it off. Do not treat it
lightly. Do not “fudge” results. The lives of the operator, oiler, and workers on the
job are depending on it.
14.2
Keep the machine clean! Oil spills, grease, loose tools, and dis-
placed accessories are hazards.
14.3
Pins should be used on all delivery system clamps. Clamps that
will hang over workers, and clamps used on system that will be dragged shall be
pinned (Figure 70).
14.4
Be sure that you are installing the correct clamps for the types
of pipe ends used. Never try to mate dissimilar pipe ends unless using a clamp
specifically made for this purpose. See the comparison regarding weld-on ends on
page 74 in the Appendix
of this Safety Manual .
