Holding Valve Inspection Procedure
The cylinders are equipped with holding
valves that prevent sudden movement of
the cylinder rods in the event of a hydraulic
hose or hydraulic component failure. The
valve is checked in the following manner:
1. Identify the cylinder in question.
2. Identify the holding valves and the
cylinder direction in question.
a. Cylinder Extend.
b. Cylinder Retract.
3. Place the machine so that the cylinder
will be located in the appropriate testing
position.
4. Pick the load (Do not exceed capacity,
rated or stability).
5. Disengage hydraulics.
6. Operate crane functions.
A. If the cylinder creeps (lowering the
load), replace the holding valve.
B. If the cylinder does not creep (load
stays suspended), the valve is
operational.
Gear-Bearing Bolt Maintenance
Anytime a gear-bearing bolt is removed, it
must be replaced with a new bolt of the
identical grade and size. Once a bolt has
been torqued to 75% of its proof load and
then removed, the torque coefficient may
no longer be the same as when the bolt was
new thus giving indeterminate damp loads
after torquing.
Warning!
Failure to replace gear-bearing
bolts may result in bolt failure due
to metal fatigue causing serious
injury or even death.
Torque Data Chart
Note: For Crane Tie Down Rods, see
Chapter 6: Installation Overview.
When using the torque data in the charts
above, the following rules should be
observed.
1. Bolt manufacturer’s particular
specifications should be consulted when
provided.
2. Flat washers of equal strength must be
used.
3. All torque measurements are given in
foot-pounds. To convert to inch-pounds,
multiply by 12.
4. Torque values specified are for bolts with
residual oils or no special lubricants
applied. If special lubricants of high stress
ability, such as Never-Seez compound
graphite and oil, molybdenum disulphite,
colloidal copper or white lead are
applied, multiply the torque values in the
charts by the factor .90. The use of Loctite
does not affect the torque values listed
above.
5. Torque values for socket-head capscrews
are the same as for rade 8 capscrews.

Type of Inspection Information
Daily and monthly inspections are to be performed by a “designated” person, who has
been selected by the employer or the employer’s representative as being competent to
perform specific duties.
Quarterly and annual inspections are to be performed by a “qualified” person who, by
possession of a recognized degree in an applicable field or certificate of professional
standing, or who, by extensive knowledge, training and experience has successfully
demonstrated the ability to solve or resolve problems related to the subject matter and
work.
One hour of normal crane operation assumes 20 complete cycles per hour. If operation
exceeds 20 cycles per hour, inspection frequency should be increased accordingly.
Consult the Stellar Owner’s Manual for additional inspection items.
Before inspecting and operating the crane, make certain that t he crane is set up away
from power lines and leveled with outriggers fully extended.
Daily (D): Before each day of operation, those items with a (D) must be inspected. This
inspection need not be recorded unless a deficiency is found.
