Preparing for the Job
Personal Protection
Concrete is made from lime, which is very alkaline. If
it stays on your skin long enough, it will cause severe
burns, and in extreme cases the a󰀨ected skin will simply
fall o󰀨. Because of this, always wear water proof gloves
and steel toed work boots. There are boots made espe-
cially for concrete work that will protect your feet from
lime and accidental impact.
Wear a hard hat at all times to protect yourself from
falling objects on the job site.
Safety goggles protect you from getting splashed con-
crete in your eyes. Anytime that there is danger of rico-
cheted rocks or sand (when shotcreting, for example),
wear a full face shield.
Snug tting work clothes will help prevent accidents in-
volving moving parts.
Concrete pumps may generate higher sound pressure
levels than O.S.H.A. allows for constant exposure.
You can protect yourself by wearing hearing protection
when on or near the concrete pump.
When mixing grout, or anytime that there will be air-
borne cement or other ne powder nearby, wear breath-
ing protection.

Pipeline and Clamps
Find out what kind of concrete you will be pumping. You
should use a pipe and/or hose system that is three to
four times bigger than the largest rock in the mix. You
can use the chart below to select the correct pipe diam-
eter for the job.
Largest stone size
Minimum pipe/hose diameter
3/8” (peagravel) 1 - 1/2”
2”1/2”
3”3/4”
4”
1”
5”
1 - 1/4”
5”
1 - 1/2”
Will you need extra pipe sections to make the pour?
Use the following checklist for pipeline needs:
• Pipe sections
• Adapter pipes
• End hoses
• Reducers
• Clamps for all pipe end styles and sizes
• Clamp Pins
Have all pipe and pipe accessories inspected for condi-
tion, loaded, and secured for travel before moving the
unit. Keep in mind the pressure rating of your unit when
you inspect the condition of pipe accessories - see the
chart regarding pipe-wall thickness versus pressure in
the Appendix section of this manual.
