Procedure
PMCS procedures in the table are intended to insure that
the crane is ready to be operated safely and with
minimum crane wear and tear.
The PMCS table lists the checks and services that need
to be performed at various intervals. The intervals were
determined by crane design and expected
use.
1.
"Before" or (B) PMCS shall be performed by the
operator prior to starting the engine and attempting
to operate the crane.
2.
"During" or (D) PMCS shall be performed while
operating the crane both while sitting in the cab
manipulating the controls and when outside the cab
doing other tasks associated with operations.
3.
"After" or (A) PMCS shall be performed after crane
operation and when it is being shut down for a period
of time.
4.
"Weekly’" or (W) PMCS need not be done every day
or every time the crane is operated, but must be
done relatively frequently, and not delayed or
forgotten. A weekly routine must be established to
check and service these items.
5.
"Monthly" or (M) PMCS provides checks and
services that need not be done weekly but cannot be
ignored more than a month. A monthly service
routine must be established.
6.
There are checks and services that must be done on
the basis of the number of hours of engine operation,
or based on special environmental conditions. These
more frequent checks are marked with an asterisk.
An appropriate footnote explains the special service
interval.
Additional Special Checks and Services
Perform weekly (W) as well as before (B) operations
PMCS if:
1.
You are the assigned operator and have not
operated the crane since the last weekly.
2.
You are operating the crane for the first time.

classified as follows:
Class I

discoloration) not great enough to form drops.
Class II

but not enough to cause drops to drip from
