What types of certificates are currently available for cranes?

Automobile crane operators are required to possess three certificates (Class B driver's license, crane operation certificate, and professional qualification certificate). The driver's license is commonly referred to as the 'off-crane certificate,' while the operation certificate is known as the 'on-crane certificate.' For those working for individual crane rental owners, possessing the latter two certificates is sufficient to meet job requirements, although having all three is preferable. Additional information: Issuance: The crane operation certificate falls under the 'Special Equipment Operation Certificate,' issued by the Quality Supervision Bureau. Previously, the 'Special Equipment Operation Certificate' was issued by local Safety Supervision Bureaus, but now it is issued by local Quality Supervision Bureaus. Training: Special equipment operators must undergo specialized safety technical training, including both theoretical and practical training, and can only start working after passing the assessments.

What are the reasons why a tricycle charger cannot charge?

Electric tricycles may fail to charge primarily due to aging batteries, damaged fuses between the electrical switches, or poor contact in the charger's wiring harness. Below are specific classifications of automotive batteries (also known as storage batteries): Conventional Lead-Acid Battery: The plates of conventional lead-acid batteries are made of lead and lead oxide, with the electrolyte being an aqueous solution of sulfuric acid. Their main advantages are stable voltage and low cost; disadvantages include low specific energy (i.e., the amount of electrical energy stored per kilogram of battery), short service life, and frequent maintenance. Dry-Charged Battery: Its full name is dry-charged lead-acid battery. The main feature is that the negative plate has a high capacity for storing electricity. In a completely dry state, it can retain the stored charge for up to two years. When in use, simply add the electrolyte and wait 20-30 minutes before it can be used. Maintenance-Free Battery: Due to structural advantages, maintenance-free batteries consume very little electrolyte and generally do not require the addition of distilled water during their service life. They also feature shock resistance, high-temperature resistance, compact size, and minimal self-discharge. Their service life is typically twice that of conventional batteries.

What are the effects of converting a gasoline car to natural gas?

When the conversion is performed properly, converting a gasoline car to natural gas will not affect the engine's lifespan. Here is relevant information: Definition: A car engine is the device that provides power to the vehicle, serving as the heart of the car, determining its power, fuel efficiency, stability, and environmental friendliness. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid systems, among others. Maintenance: Car engines require regular maintenance. When driving through particularly humid or dusty areas, it is also necessary to inspect and maintain relevant engine components.

What lights to use when parking on the roadside?

Temporary parking requires turning on the turn signal in the direction of parking, usually the right turn signal. The roadside parking light is a parking warning function set by the car. When the car is parked on the roadside, the left parking light keeps flashing. This function is mainly used to remind passing vehicles at night to avoid collisions. In case of fog, rain, snow, or when parking at night or under special circumstances, such as parking on the emergency lane of a highway, the hazard warning lights need to be turned on. After turning on the hazard warning lights, all four turn signals (front and rear) will light up simultaneously, which can alert other vehicles in poor visibility at night and help avoid accidents. Here is a related introduction about adjusting car lights: Adjustment of low beam: Vehicle light adjustment usually involves the left-right and up-down alignment of the low beam, which can be adjusted via the knobs behind the headlight assembly. Owners can adjust the lights themselves using tools. Headlight adjustment: Lift the engine hood and locate the adjustment knobs behind the headlight assembly. Use the appropriate tools to adjust them. Before adjusting, determine whether the knob adjusts left-right or up-down. Park the vehicle facing a wall at a distance of about 10 meters, observe the height of the left and right lights, and use tape or other markers for measurement and comparison if necessary, then proceed with adjustment.

Small vehicle Subject 2 test items: Include five mandatory tests—reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-turns) (some areas include a sixth item: high-speed card collection). Large vehicle Subject 2 test items: Include stake test, stopping and starting on a slope, parallel parking, passing a single-plank bridge, curve driving, right-angle turns, passing a width-restricted gate, passing continuous obstacles, driving on undulating roads, narrow road U-turns, as well as simulated highways, continuous sharp turns on mountain roads, tunnels, rain (fog) conditions, slippery roads, and emergency handling.

Why does the electric tricycle not move when the throttle is twisted with no response?

Reasons why the electric tricycle throttle cannot be twisted are as follows: Check the electric vehicle battery: If the output is too low, it indicates the battery is faulty and needs immediate replacement. Check the throttle handle: Use a wire to short-circuit the positive terminal and signal wire of the throttle handle. If the vehicle moves, it means the throttle handle is faulty and needs immediate replacement or repair. Check the controller: You can short-circuit the positive 5V of the throttle handle wire. If the throttle handle twists, it indicates the controller is functioning properly. The simplest method is to smell the controller for any burnt odor, which would indicate controller damage. Check the motor condition: Poor contact of the motor carbon brushes can also cause the electric vehicle to not move.
