Scope

Scope: This standard specifies the stress testing methods for the main structural components of general bridge cranes. This standard applies to general bridge cranes in workshops, and other similar bridge cranes may refer to it for use. Main technical content: 5. Structural stress testing 5.1 Test conditions and loads The test conditions and loads for general bridge cranes shall comply with the requirements of Table 1. Table 1: Stress testing conditions and loads **Serial number** **Test condition** **Test purpose** **Test items** 1 The trolley is located at the center of the span, and the rated load is lifted by 1.25 times, with the trolley being approximately 300 mm above the ground and kept stationary. **Verify the strength and rigidity of the main beam** **Main beam** - Static stress at the center of the main beam cover plate; - Static stress at the center of the main beam end cover plate. 2 The trolley is located at the center of the span, and the rated load is lifted by 1.1 times, with the trolley being approximately 1.5 meters above the ground. The load is lowered at the rated speed, and the trolley is stopped during the descent. **Verify the strength and rigidity of the main beam** **Main beam** - Dynamic stress at the center of the main beam cover plate; - Dynamic stress at the center of the main beam end cover plate. 3 The trolley is located at the center of the span, and the rated load is lifted by 1.1 times, with the trolley being approximately 300 mm above the ground. The trolley is moved at the rated speed, and the trolley is stopped during the movement. **Verify the strength and rigidity of the main beam** **Main beam** - Dynamic stress at the center of the main beam cover plate; - Dynamic stress at the center of the main beam end cover plate. 4 The trolley is located at the center of the span, and the rated load is lifted by 1.1 times, with the trolley being approximately 300 mm above the g
