Iowa Code r. 875-72.11 - Wind tower lifts
Wind tower lifts authorized by this rule shall not be installed in grain elevators, high-rise buildings, water towers, television towers or any facility other than a wind tower built for the production of electricity. This rule applies to all wind tower lifts, whether installed before or after May 28, 2008; however, this exception does not apply to a wind tower lift if the contract for its installation is executed after an AECO is accredited.
(1) Wind tower lifts that meet the
requirements of subrules 72.11(2) through 72.11(9) are exempt from the
requirements of ASME A17.1. This temporary exemption terminates for a wind
tower lift upon the occurrence of at least one of the following events:
a. Three weeks have passed since the
accreditation of at least one AECO, and the manufacturer of the wind tower lift
has not filed with the director an affidavit attesting that a request for
Certificate of Conformance as described by ASME A17.7 (2007) was submitted to
an AECO.
b. The AECO has reviewed a
request pursuant to ASME A17.7 and refused to issue a Certificate of
Conformance for the model or series of lifts.
c. The AECO has determined that modifications
to the wind tower lift are necessary, and the modifications have not been made
with reasonable diligence.
d. The
AECO has determined that modifications to the wind tower lift are necessary,
and the director determines the wind tower lift is not safe to operate prior to
completion of the modifications.
e.
The AECO has reviewed an application pursuant to ASME A17.7 and issued a
Certificate of Conformance for the model or series of lifts.
(2) A wind tower lift placed in
operation on or before May 28, 2008, shall be registered by the owner with the
director no later than July 1, 2008, and shall pass an installation inspection
by inspectors employed by the director according to the schedule set by the
director. The wind tower lift shall receive a periodic inspection by the
director annually thereafter.
(3)
The owner of a wind tower lift installed after May 28, 2008, shall register the
wind tower lift with the director prior to its installation. A wind tower lift
installed after May 28, 2008, shall pass an installation inspection by the
director prior to its being placed into operation. The wind tower lift will
receive a periodic inspection annually thereafter.
(4) Registration pursuant to this rule
requires submission of the following information to the director:
a. The unique identifier of the wind
tower.
b. The name of the wind
tower owner and contact information for the owner's representative.
c. The name of the wind tower lift
manufacturer and contact information for the manufacturer's
representative.
d. The location of
the wind farm.
e. Three copies of
the prints and design documents that are certified by a professional engineer
duly licensed in the state of Iowa and that bear the professional engineer's
P.E. stamp for the lifts.
f. The
manufacturer's complete test procedures, inspection checklists, operating
manual, service manual, and related documents as determined necessary by the
director.
(5) The owner
shall notify the director within 30 days of any change in the information
provided pursuant to paragraphs 72.11(4)"b" and
"c."
(6) The
manufacturer of a lift must notify the director in writing within one week if
one of its wind tower lifts anywhere in the world is involved in a personal
injury accident requiring the service of a physician, a personal injury
accident causing disability exceeding one day or death, or an incident causing
property damage exceeding $2,000. The notification shall specifically identify
the model number, serial number, and owner of the lift, and a description of
the incident or accident. The director shall determine and require necessary
inspections, tests, changes or enhancements to prevent a similar incident or
accident in this state.
(7) The
manufacturer shall notify the director within seven days of notification to the
manufacturer that an AECO has:
a. Issued a
Certificate of Conformance for the model or series of wind tower
lifts,
b. Refused to issue a
Certificate of Conformance for the model or series of wind tower lifts,
or
c. Determined that modifications
to the wind tower lifts are necessary.
(8) Wind tower lifts shall pass an inspection
covering the following criteria:
a. Ascending
speed, descending speed, and emergency descending speed will not exceed the
manufacturer's recommendations.
b.
Stop switch, interior lighting, cage entry door, door contact, operating

o.
Maintenance logs, tags, and other necessary documentation will be available in
sufficient detail to establish that maintenance is occurring pursuant to the
