Mobile crane operation certificates are uniformly issued by the Quality and Technical Supervision Bureau. The following are precautions for crane operators: 1. Crane Operators: Crane operators must undergo specialized training and pass assessments conducted by relevant authorities to obtain a qualification certificate before being allowed to operate. Unauthorized personnel are strictly prohibited from operating lifting equipment. Before performing lifting operations, crane operators must check whether all devices are functioning normally, whether steel cables meet safety regulations, and whether brakes, hydraulic devices, and safety equipment are complete, reliable, and responsive. Operating any part of the crane with faults is strictly prohibited. Crane operators must work closely with signalers and follow their instructions. A horn must be sounded before operation. If the signal is unclear or incorrect, the operator has the right to refuse execution. During operation, the operator must immediately comply with any emergency stop signal from anyone and can only resume work after eliminating unsafe factors. 2. Signalers: Signalers must clearly communicate instructions to crane operators beforehand. If signals are unclear during operation, an intermediary assistant should be appointed to accurately relay signals. Hand signals should be clear and unambiguous, and signaling with gloves is prohibited. Before lifting an object, check whether the binding is secure. Padding should be placed where ropes pass over edges or sharp corners. The lifting point's center of gravity must be accurate, and the object must not twist, bend, sink, or tilt under force. Before the lifted object is secured in place, the crane operator must not leave the workstation or interrupt work while the sling is under tension or the object is suspended. If the crane operator refuses to lift due to overweight, the signaler should take measures to reduce the overload. Forcing the crane to operate under overload is strictly prohibited.

Can You Get a Driver's License with Poor Eyesight?

Yes, you can get a driver's license with poor eyesight. If your corrected vision (with glasses) reaches 4.9 or above on the logarithmic visual acuity chart, you can apply for a Class C license. However, if you have amblyopia in one or both eyes, with uncorrected vision below 4.9 and no possibility of correction, you do not meet the requirements for a driver's license and cannot take the test. For large buses, medium buses, tractors, city buses, large trucks, trolleybuses, or trams, the uncorrected or corrected vision must reach 5.0 or above on the logarithmic visual acuity chart. The "Regulations on the Application and Use of Motor Vehicle Driving Licenses" stipulate in Article 12 that applicants for a motor vehicle driving license must meet the following vision requirements: For large buses, tractors, city buses, medium buses, large trucks, trolleybuses, or trams, the uncorrected or corrected vision must reach 5.0 or above on the logarithmic visual acuity chart. For other vehicle types, the uncorrected or corrected vision must reach 4.9 or above on the logarithmic visual acuity chart. Therefore, if your uncorrected vision does not meet the standard, you can still qualify for a driver's license by wearing glasses or other corrective measures to achieve 4.9 or above on the logarithmic visual acuity chart. Driver's license test requirements for physical examination: Height: For large buses, tractors, city buses, large trucks, or trolleybuses, the height must be at least 155 cm. For medium buses, the height must be at least 150 cm. Vision requirements: For large buses, medium buses, tractors, city buses, large trucks, trolleybuses, or trams, the uncorrected or corrected vision (with glasses) must reach 5.0 or above on the logarithmic visual acuity chart. For other vehicle types, the uncorrected or corrected vision must reach 4.9 or above. Color vision: No red-green color blindness. Hearing: Must be able to distinguish the direction of sound at a distance of 50 cm from a tuning fork in each ear. Upper limbs: Both thumbs must be intact, and each hand must have at least three other fingers intact, with normal movement and function. Lower limbs: Normal movement function. For manual transmission vehicles, the difference in leg length must not exceed 5 cm. For automatic transmission vehicles, the right lower limb must be intact. Torso and neck: No movement dysfunction. Driver's license test content: Subject 1: After registration, applicants must attend a face-to-face lecture before scheduling the Subject 1 test. Subject 1 is a written test consisting of 100 multiple-choice and true/false questions, with one point per question. A score of 90 or above is required to pass. Subject 2: Subject 2 consists of five mandatory tests: reverse parking, parallel parking, hill start, curve driving, and right-angle turns. The test is scored out of 100, with a passing score of 80 or above. Subject 3: Subject 3 is a road test that includes preparation before driving, starting, straight-line driving, gear shifting, lane changing, parking, passing through intersections, left and right turns, crossing pedestrian crossings, passing school zones, passing bus stops, meeting vehicles, overtaking, U-turns, and simulated lighting operations. Subject 4: Subject 4 can be taken the day after passing Subject 3. It consists of 50 questions, including multiple-choice and single-choice questions, with a full score of 100. A score of 90 or above is required to pass.

What to Do When a Nail is Stuck in the Tire Without Air Leakage?

If a nail is stuck in the tire while driving without causing air leakage, it is recommended not to pull out the nail by yourself. Here are some relevant introductions about a nail stuck in the tire: 1. Solution: Drive the car to a professional tire shop and let the staff pull out the nail and check the puncture. Since the tire is in a rolling state while driving, the nail may not be vertically stuck into the tire. If it is pulled out without timely repair, it may damage the tire sidewall, which may make it impossible to repair. 2. Situations where a nail-stuck tire cannot be repaired: (1) Damage to the tire sidewall cannot be repaired. (2) A puncture hole in the tire crown with a diameter exceeding 6 mm cannot be repaired. (3) Other situations include damaged or deformed bead, deformed tread, rubber corroded by chemicals, or damage caused by running the tire flat.

What Are the Reasons for No Response When Turning the Vehicle Key?

There are many potential reasons why a car key fails to start the engine. It could be due to a dead battery, wiring issues, insufficient fuel, or problems with components in the fuel system, ignition system, or exhaust system. Below are more relevant details: 1. Car Gear Position: An incorrect gear position can also prevent the car from starting. Generally, the P (Park) or N (Neutral) gear is the correct position for starting an automatic transmission vehicle. If the driver accidentally leaves the gear in R (Reverse) or another position, it may not only fail to start but also pose a safety hazard. 2. Car Electrical Circuit: If the issue is related to the electrical circuit, the failure to start may occur suddenly. Common faults that cause no response when turning the key include blown fuses, open circuits in the high-voltage coil or low-voltage circuit, detached central ignition wire, leaking distributor rotor, or damaged spark plugs.

Do modern cars still have a water tank?

Yes, cars do have a water tank. Here is some relevant information about car water tanks: 1. The liquids added to the water tank: The water tank near the front of the car is for adding windshield washer fluid, while the one near the car's windshield is for adding antifreeze. Neither windshield washer fluid nor antifreeze can be replaced with tap water. 2. The difference between antifreeze and water: Antifreeze has a boiling point above 120 degrees Celsius, whereas water boils at only 100 degrees Celsius. Using antifreeze in cars can prevent "boiling over" in the summer. Using water instead of antifreeze can easily lead to scale buildup and requires frequent replacement, whereas antifreeze does not have these issues. Water can also be somewhat corrosive to the cooling system, while antifreeze includes anti-corrosion and anti-rust properties.

Can the car cigarette lighter be used for charging?

Car cigarette lighters cannot be used for charging, for the following reasons: 1. Different voltage: Unlike household sockets, the cigarette lighter operates at 12V, while mobile phone charging requires around 5V. 2. Impact on electronics: Since the cigarette lighter is directly connected to the car battery, when the car starts, the current will suddenly increase. The cigarette lighter itself has no protection. However, electronic devices require a constant power supply for charging. Sudden current fluctuations can cause damage, and prolonged use under such conditions will reduce the lifespan of electronic products.

What are the solutions for CR-V's low-speed jerking?

The solutions for CR-V's low-speed jerking involve paying more attention to the shifting RPM. The upshift RPM is usually between 2000 and 2500, while the downshift RPM is typically around 1500. During low-speed driving, frequent switching between first and second gears causes the clutch to continuously engage and disengage, which can lead to incomplete power transmission in a short time, resulting in common low-speed jerking. If jerking occurs, the following steps should be taken: 1. Determine if the jerking is normal: Generally, if the jerking sensation is consistent, it is normal, but if it suddenly feels different one day, there might be an issue. 2. Check the transmission temperature: Ensure the transmission temperature is normal; if not, inspect the transmission cooling system. 3. Reprogram the settings: Reset the transmission control module system. 4. Replace the transmission fluid: Transmission fluid should be replaced every 2 years or 40,000 kilometers. 5. Inspect the internal valve body of the transmission: Check if the internal valve body of the transmission is damaged.
