Requirements.

NOTE

A test load, when required by paragraph 4, may exceed

the manufacturer's rated load as much as the applicable

percentage in Table 1.

NOTE

The requirements of Title 29, Code of Federal Regulations,

Parts 1915, 1917, 1918, and 1919 take precedence over this

bulletin for lifting devices used in maritime application.

a. Testing.

(1) Prior to initial use, all new, extensively repaired, or altered lifting devices shall be given a

rated load test. Manufacturers and repair activities should perform this test and provide written

certification of load testing to the using activity. If load test certification is not obtained or available,

using activities shall arrange for testing (refer to paragraph 4a(4)), through General Support (GS) or

Direct Support (DS) maintenance activities. Manufacturer's certification or other records of rated load

testing shall be maintained by the using activity.

(2) Prior to initial use, all new, extensively repaired, or altered lifting devices shall be given a

functional test to determine operability of the equipment. Functional testing requirements are

indicated in the applicable appendix of this bulletin. Before performing the functional test, the proper

operation of brakes and limit, locking, and other safety devices shall be tested under no-load

conditions.

(3) Lifting devices which have been idle for one year or more shall be functionally tested at

100 percent of the rated load prior to use.

(4) To determine the test load, refer to Table 1 unless other parameters are specified by the

manufacturer. The load rating may be less than or equal to, but shall not exceed the Manufacturer's

Rated Load. For fixtures, the smallest Manufacturer's Rated Load component shall equal the fixture's

rated load.

(a) Test loads for all types of cranes and hoists may take the form of a calibrated load

indicator, a calibrated dynamometer, weights that may be locally fabricated, or any available item of

proper weight. All load testing devices, i.e., load indicator and dynamometer, shall have a valid

calibration label affixed in a conspicuous place. All locally fabricated weights and available items used

for load testing must be verified for proper weight by the use of a calibrated scale.

(b) Test loads for forklift trucks should be made from pallet loads with load center

locations corresponding to Manufacturer's Rated Load data.

(5) Upon successful completion of the load test, the lifting device will be assigned the load

rating chosen in (4) above. The load rating shall be clearly marked on the device. In addition, the

load rating shall become a part of the maintenance records of the equipment in accordance with

(6) Preventive maintenance intervals and additional load testing may be established locally

based on the type of materials handled, equipment utilization, local requirements or conditions,

manufacturer's recommendations, and special requirements.
