CHANGING THE PARADIGM
Truth vs. Fiction
For years the manufacturers have pushed
new versus repair to crane owners Dont confuse manufacturer policy with
Federal law
Manitowoc & Tadanoare taking the
lead as they understand the importance of
taking care of the customer

CAN A REPAIR BE
BETTER THAN NEW?
Yes!
Manufacturing is process driven and
processes can be faulty and variationsoccur
We know this because we see it in
product that comes to us for repair
We know this because we see it in new
product we purchase for replacement

OSHA
The new OSHA Standard addresses
repaired/adjusted equipment in the 1900.1412
under the title Inspections,specifically
1900.1412 (b)(1) Essentially, regular inspections to cranes are
required by federal law. So if a repair or
adjustment has been made to a crane it
needs to be inspected by a qualified
person prior to being put back into service.

OSHA
1926.1412 (b)(1) specifically provides for
the qualified person to use the OEM
criteria or an RPE (registered professional
engineer) to develop criteria for the repair
or adjustment.

OSHA
The manufacturers are very quick to say that
if they do not perform the repair that it then
becomes a modification, which then under
OSHA regulations they say requires the
approval of the manufacturer.

OSHA
OSHA does say that, however they also
have a provision if the manufacturer
refuses to review the request or declines to
review the technical merits of the proposal
then a qualified person is allowed. OSHA
regulations are also there to protect the
interests of the crane owners as well asthe insurance companies.
-

OSHA
Where manufacturer equipment criteria are
unavailable or inapplicable, the qualified
person can determine if a registered
professional engineer (RPE) is needed to
develop criteria for the repair/adjustment. If
an RPE is not needed, the employer must
ensure that the criteria are developed by thequalified person. If an RPE is needed, the
employer must ensure that they are
developed by an RPE.
