Bolt fastening degree, rope clip spacing and safety bend (rope head) setting do not meet the requirements, and each item will be deducted 2 points. 3. Threading pulley block 3. 1, tester 1, pulley block 2, 4 m long hemp rope (or chemical fiber rope) 2, timer 1; 2 personal safety protection articles. 3.2 The examination method is that the examinee passes a pulley block by straight penetration and flower penetration respectively. 3.3 Evaluation time: 5min. 3.4 The full score of the evaluation criteria is 10. Within the specified time, if the threads are correct and standardized, each pair will get 5 points; If the threading is basically correct, but not standardized, 2 points will be deducted for each pair. 4. Weave several sections of hemp rope (or chemical fiber rope) with the length of 1 m by knotting 4. 1 tester1; 2 Other electrical appliances: 1 timer. 4.2 Examination Method Candidates weave two kinds of knots and explain their applicable occasions. 4.3 Evaluation time: 5 minutes. 4.4 The full mark of the evaluation standard is 10. 5 points for each type, if it is edited correctly within the specified time, and its application is correctly explained; If the editor typed correctly, but could not explain the application correctly, 3 points will be deducted for each type; If there is an error in editing and typing, but it can correctly explain its application situation, add 2 points for each type. 5. Identification and judgment of lifting slings, rigging and machines. 5. 1 evaluation instrument 1 several wire ropes with different specifications; 2. Physical objects, graphics and image data of crane, rigging and equipment such as discharge port, rope clamp, jack, chain block, grinder, chain block and electric hoist; 3 Other electrical appliances: 1 timer. 5.2 Examination method 1 Randomly select 2 steel ropes with different specifications, and the candidates will judge the specifications of the steel ropes; 2 Five kinds of heavy lifting, rigging and equipment are randomly selected from physical objects or graphics and image data, and the candidates will identify and explain their names. 5.3 Examination time: l0min. 5.4 The full score of the evaluation criteria is 10. Correctly judge a wire rope of a specification within the specified time, and get 2.5 points; If you correctly identify a lifting sling, rigging and machine within the specified time, you will get 1 point. 6. Reject the wire rope, shackle, rope clamp, hook 6. 1 inspection instrument 1 wire rope, shackle, rope clamp, hook and other physical or graphic image materials (including those that meet the scrapping standards and are defective) 2 Other instruments: 1 timer. 6.2 Evaluation Method 4 pieces (sheets) are randomly selected from wire rope, shackle, hook, rope clamp or graphic image data, and the examinee will judge whether it meets the scrapping standard or has defects, and explain the reasons. 6.3 Inspection time: 8 minutes. 6.4 The full score of the evaluation criteria is 10. If you correctly judge and explain the reasons within the specified time, each item will get 2.5 points; If the judgment is correct but the reason cannot be accurately explained, each item will get 1 point. 7. Weight estimation 7. 1 Evaluation instrument 1 Several steel ropes and hemp ropes of various specifications; 2. Steel members (simple members composed of pipes, wires, plates and profiles) are physical objects or graphic and image materials; 3 Other electrical appliances: 1 timer; 4 personal safety protection articles. 7.2 assessment method 1 randomly select one of various specifications of steel wire rope and hemp rope, and the examinee calculates the breaking tension and allowable tension of steel wire rope and hemp rope respectively; 2 Two kinds of steel members or graphic and video materials are randomly selected, and the examinee estimates their weight and judges their center of gravity. 7.3 Evaluation time: l0min.
