20-1.3.1
Inspection Classification
|
 |
A. |
Initial Inspection |
1. |
New
and reinstalled lifters shall be inspected by a
designated person prior to initial use to verify
compliance with applicable provisions of this
volume. Lifters manufactured by TANDEMLOC,
Inc. are proof tested prior to delivery of the
lifter, the user must confirm this by reviewing
the test date plate on the lifter and the proof
test certificate. |
2. |
Altered, repaired, or modified lifters shall be
inspected by a designated person. The
inspection may be limited to the provisions
affected by the alteration, repair, or
modification, as determined by a qualified
person. |
 |
B. |
Inspection Intervals
Inspection procedure for lifters in regular service is
divided into two general classifications based upon
the intervals at which inspection should be
performed. The intervals, in turn, are dependent upon
the critical components of the lifters and the degree
of their exposure to wear, deterioration, or
malfunction. The two general classifications are
herein designated as frequent and periodic,
with respective intervals between inspections as
defined below. |
1. |
Every
Lift Inspection: Visual examination by the
operator before and during each lift made by the
lifter. |
2. |
Frequent Inspection: Visual examinations by the
operator or other designated persons with records are
not required.
| a. |
Normal
service - monthly. |
| b. |
Heavy
Service - weekly to monthly. |
| c. |
Sever
service - daily to weekly. |
| d. |
Special or
infrequent service - as recommended by a
qualified person before and after each
occurrence. |
|
3. |
Periodic Inspection. Visual inspection by a qualified
person making records of apparent external conditions
to provide the basis for a continuing evaluation. An
external code mark on the lifter is an acceptable
identification in lieu of records.
| a. |
Normal
service for equipment in place - yearly. |
| b. |
Heavy
service [as in (a) above, unless external
conditions indicate that disassembly should
be done to permit detailed inspection] -
semiannually. |
| c. |
Severe service [as in (b) above] - quarterly. |
| d. |
Special or infrequent service - as recommended by a
qualified person before the first such occurrence and
as directed by the qualified person for any subsequent
occurrences. |
|
 |
20-1.3.2 Every Lift Inspection
Items such as the following shall be inspected by the
operator before and/or during every lift for any
indication of damage a specifically indicated,
including observations during operation for any
damage that might occur during the lift: |
 |
A. |
Surface of the load for debris. |
 |
B. |
Condition and operation of the controls. |
 |
C. |
Condition and operation of the indicators and meters
when installed. |
 |
20-1.3.3 Frequent Inspection (See Also Table 1)
Items such as the following shall be inspected for damage at
intervals as defined in paragraph
20-1.3.1(B)(2), including observations during
operation for any indications of damage that
might appear between inspections. A
qualified person shall determine whether any
indications of damage constitute a hazard or
will require more frequent inspection. For
all lifters, inspect: |
 |
A. |
Structural members for deformation, cracks, or
excessive wear on any part of the lifter. |
 |
B. |
Loose
or missing guards, fasteners, covers, stops, or
nameplates. |
 |
C. |
All
functional operating mechanisms and automatic
hold-and-release mechanisms for maladjustments
interfering with operation. |
 |
20-1.3.4 Periodic Inspection (See Also Table 1)
Complete inspection of the lifter shall be performed at
intervals as defined in paragraph
20-1.3.1(B)(3). Any deficiencies, such as
listed below, shall be examined and
determination made as to whether they constitute
a hazard. These inspections shall include
the requirement of paragraph 20-1.3.3 and, in
addition, items such as the following: |
 |
A. |
Loose
bolts or fasteners. |
 |
B. |
Cracked or worn gears, pulleys, sheaves, sprockets,
bearings, chains, and belts. |
 |
C. |
Excessive wear of friction pads, linkages, and other
mechanical parts; and |
 |
D. |
Excessive wear at hoist hooking points and load
support clevises or pins. |
| |
 |
20-1.3.5 Lifting Devices Not In Regular Use
A lifter that has been idle for a period of 1 month or more
is to be given an inspection in accordance with
paragraph 20-1.3.3 before being placed in service. |
| |
| |
20-1.3.6 Inspection Records
Dated inspection reports shall be made on critical items such
as those listed in paragraph 20-1.3.4. Records should
be available to appointed personnel for each periodic
inspection and when the lifter is either modified or
repaired. |
| |
| |
20-1.3.7 Repairs
Any indications of damage disclosed by the inspection
requirements of Section 20-1.3 shall be corrected
according to the procedures outlined in paragraph
20-1.3.9 before operation of the lifter is resumed. |
20-1.3.8 Testing |
20-1.3.8.1 Operational Tests |
 |
A. |

20-1.3.8.2 Load Test |
 |
A. |
Prior
to initial use, all new, altered, modified, or
repaired lifting devices should be tested and
inspected by, or under the direction of, a
qualified person and a written report be
furnished by such a person, confirming the load
rating of the lifter. The load rating
should not be more than 80% of the maximum load
sustained during the test. Test loads

unless otherwise recommended by the
manufacturer. Test reports should be
available. |
 |
B. |
The
load test, if made, shall consist of the following
operations as a minimum requirement. |
1. |
Hoist
the test load a sufficient distance to ensure the load
is supported by the lifter, or apply the required if
the test is made using a testing machine.
|
2. |
After
the test load is released, visually inspect the
lifter for deformation, cracks, or other
defects. |
 |
C. |
Altered, repaired, or modified lifters shall be tested
by a qualified person, or a designated person under
the direction of a qualified person. This test may be
limited to the provisions affected by the alteration,
repair, or modification, as determined by a qualified
person with guidance from the manufacturer. |
