Content:
the proper assembly of electrical and structural com- ponents should be verified. The integrity of all control, operating, and safety systems should be verified as to satisfaction of installation and design requirements, The crane designer and crane manufacturer should provide a manual of information and procedures for uise in checking, testing, and operating the crane. The manual should also describe a preventive maintenance program based on the approved test results and informa- tion obtained during the testing; it should include such items as servicing, repair and replacement requirements. visual examinations, inspections, checking, measure- ments, problem diagnosis, nondestructive examination, crane performance testing, and special instructions. Information concerning proof testing on components and subsystems as required and performed at the manufacturer's plant to verify the ability of components or subsystems to perform should be avail- able for the checking and testing performed at the place of installation of the crane system. b. The crane system should be prepared for the static test of 125% of the design rated load. The tests should include all positions of hoisting, lowering, and trolley and bridge travel with the 125% rated load and other positions as recommended by the designer and manufacturer. After satisfactory completion of the 125% static test and adjustments required as a result of the test, the crane handling system should be given full performance tests with 100% of the design rated load for all speeds and motions for which the system is designed. This should include verifying all limiting and safety con- trol devices. The crane handling system with the design rated load should demonstrate its ability to lower and move the load by manual operation and with the use of emergency operating controls and devices that have been designed into the handling system. The complete hoisting machinery should be allowed to "two block" during the hoisting
