23. CONTROL VALVE AND JACK
The spool slides to different positions in the housing, and
intersecting grooves and channels route the fluid based on
the spool's position.
24. HOW THE WORK CONTROL VALVE
The spool has a central (neutral)
position maintained with springs;
in this position the supply fluid is
blocked, or returned to tank.
Sliding the spool to one side
routes the hydraulic fluid to an
actuator and provides a return
path from the actuator to tank.
When the spool is moved to the
opposite direction the supply and
return paths are switched. When
the spool is allowed to return to
neutral (center) position the
actuator fluid paths are blocked,
locking it in position
26. QUALITY INSPECTION
INCOMING INSPECTION:-
Garbage in, garbage out‖: a factory usually cannot turn defective inputs
(components, or raw materials) into good products. And the problems are much
harder to detect once the materials are embedded in the final product.
ON LINE INSPECTION:-
Typically, in an in-line inspection, the first products that got out of the line are
inspected for conformity. If issues are raised at this stage, the factory can
immediately take some corrective actions and avoid delays.
TESTING:-
An inspection performed on the cranes in which they have to go through
various load and road test, as per the specifications to ensure their effective
working on the fields.
27. QUALITY INSPECTION
REWORK:-
A stage which comes after testing, where every minute parts of the crane are
observed carefully to check whether there is any defect that has been raised
after testing the crane at its full capacity. It also includes observing any leakage
and re-torqueing all the hardware components to ensure safety.
PDI (PRE-DISPATCH INSPECTION):-
This is the most popular type of QC inspection for importers. It takes place
once all the products are finished and ready for shipment.
AUDIT:-
The final stage after dispatch where from ‗N‘ no of cranes randomly few
cranes are selected and then these machines are inspected as per the pre-
defined check points.
