This service is perhaps the most important aspect of any
equipment purchase. This is the time when actual performance is measured and
evaluated against specified requirements and unspecified industry standards.
We do not direct the OEM’s erectors and vendors but we are
available as advisors when a solution to a perplexing problem can benefit from
our past experience and expertise. As with construction inspection, the
appropriate level of our efforts depends on the buyer’s judgment and
authorization.
This is a specialty service where CP&A’s multi‑discipline
expertise is particularly valuable. Major equipment such as a container crane
is a complex system where electrical, computer science, mechanical, and
structural engineering have to function together as a complete system. When
there is a problem with one specialty it is important to be aware of how that
problem can create secondary problems with any or all of the other specialties.
One common example has been an overly flexible gantry frame that leads to
malfunction of the mechanical anti‑sway system that is electrically controlled
by custom PLC software. Or a resonant mechanical vibration problem that will
induce premature structural fatigue and risk of brittle fracture in a structural
member.
