  • Development history of truck crane in China

          China's truck crane was born in the 1970s, after nearly 30 years of development, there have been three major technical improvements, respectively, the introduction of Soviet technology in the 1970s, the introduction of Japanese technology in the 1980s, the introduction of German technology in the 1990s. But in general, China's truck crane industry has always been on the road of independent innovation, with its own clear development context, especially in recent years, China's truck crane industry has made considerable development, although there is a certain gap compared with foreign countries, but the gap is gradually narrowing. Moreover, the performance of small and medium tonnage truck cranes in China is in good condition, which can meet the requirements of actual production       China's truck crane industry has gone through the development process from imitation to independent research and development, from small load to large load. In the early stage of development, foreign advanced technology was mainly introduced, and there were three important technology introductions, including Soviet technology in the 1970s, Japanese technology in the early 1980s and German technology in the early 1990s. Restricted by the level of science and technology at that time, the lifting capacity of truck cranes before the 1990s was relatively small, between 8 tons and 25 tons, and the technology was not mature. Brand model, the original Taian QY series truck crane by the user's praise.       After China's entry into WTO in 2001, the demand for domestic truck cranes is increasing, and the market also stimulates manufacturers to produce products with higher quality, stronger performance, better safety and more able to meet the needs of work. After entering the 21st century, many domestic truck crane manufacturers have carried out mergers and acquisitions, and the domestic truck crane industry with Zoomlion Zhongke, Sany Heavy Industry, XCMG and Liugong as the new main forces has entered the stage of independent research and development. With the joint venture of Taian Dongyue and Manitowoc, and the joint venture of Changjiang Qigong and Terex, foreign manufacturers have also joined in the competition of domestic truck cranes.       With the development of the crane industry, the improvement of the technical level makes it possible to improve the lifting capacity of the crane. The potential of the truck crane in flexibility, lifting capacity and effective working space is gradually exploited to meet the needs of different work. After entering the 21st century, the lifting capacity of the new generation of truck crane is higher and higher, and the technology is more and more mature.       From 2005 to 2010, there was a general boom in the whole construction machinery industry, and the sales volume of truck crane also reached a new high. After years of rapid development, truck crane has reached the world leading level. In November 2010, Xugong's large tonnage truck crane qy160k appeared in Shanghai BMW exhibition. Qy160k is the world's largest truck crane at present.       Since 2011, the truck crane industry and the whole construction machinery industry have been in a downturn. However, the infrastructure construction is still not stopped, the future demand of truck crane is still strong, manufacturers and users are looking forward to the return of peak season. After the adjustment of the truck crane market, will be more standardized and more orderly, we are also looking forward to the emergence of more and better truck crane products.

  • Precautions of crane in use

          Crane belongs to heavy machinery, when we encounter crane construction, we should pay attention to the whole, if necessary, take the initiative to avoid danger, today we will talk about the precautions of crane use!       1. Set all control handles to zero position and ring the alarm before driving.       2. Test run each mechanism with empty vehicle first, and judge whether each mechanism is normal or not. If the brake on the crane fails or is not adjusted properly, the crane is forbidden to work.       3. When lifting heavy objects for the first time in each shift, or when lifting heavy loads at other times, the heavy objects should be put down 0.2m above the ground to check the brake effect, and then put into normal operation after meeting the requirements.       4. When the crane is close to other cranes on the same span or upper layer, it must keep 1_ Distance above 5m: when two cranes lift the same object, the minimum distance between cranes shall be kept above 0.3m, and the load on each crane shall not exceed 80% of the rated load       5. The driver must strictly abide by the command signal on the crane. Do not drive until the signal is not clear or the crane has left the dangerous area.       6. In case of improper hoisting method or possible danger during hoisting, the driver shall refuse hoisting and put forward improvement suggestions.       7. For cranes with main and auxiliary hooks, it is not allowed to use two hook heads to lift two heavy objects at the same time. The hook head that cannot be made shall be lifted to the limit position, and the hook head is not allowed to hang other auxiliary lifting tools.       8. When lifting heavy objects, they must be lifted in the vertical direction, and dragging and inclined lifting are prohibited. Lifting is not allowed when the hook head rotates.       9. When approaching the end of the track, the cart and trolley of the crane shall slow down and approach at a slow speed to avoid frequent collision with the rack       10. The crane shall not collide with another crane. Only when one crane breaks down and the surrounding conditions are known, it is allowed to use a crane without load to slowly push another crane without load.       11. The lifted heavy objects shall not stay in the air for a long time. In case of sudden power failure or sharp line voltage drop, the controller handle shall be returned to zero position as soon as possible, the main switch (or main switch) in the distribution protection cabinet shall be cut off, and the crane operator shall be informed. If the heavy object is suspended in mid air due to sudden reasons, the driver and the crane worker shall not leave the post, and other personnel on the site shall be warned not to pass through the dangerous area.       12. When the brake of the lifting mechanism suddenly fails in operation, it is necessary to deal with it calmly. If necessary, turn the controller to the low gear to make slow and repeated lifting action. At the same time, drive the cart and trolley, and select the safe area to put down the heavy objects.       13. For continuous working cranes, each shift shall have 15-20 minutes for cleaning and inspection.       14. When lifting liquid metal, harmful liquid or important goods, no matter how heavy they are, they must be lifted 200 ~ 300 mm above the ground first, and then formally lifted after verifying that the brake works reliably.       15. It is forbidden to lift heavy objects buried underground or frozen on other objects. It is forbidden to use spreaders to tow vehicles.       16. It is forbidden to load and unload materials in the same carriage or cabin with spreader (lifting electromagnet) and manpower at the same time.       18. When two cranes transport the same object, the weight shall not exceed 85% of the total lifting capacity of the two cranes, and each crane shall not be overloaded.       20. When the crane is working, no one is allowed to stay on the crane, trolley and crane track.       21. The hoisted heavy objects run on the safe passage.       22. When running on the line without obstacles, the bottom of the spreader or heavy object must be lifted more than 2m away from the working face.       23. When it is necessary to cross the obstacle on the running line, the bottom surface of the spreader or heavy object shall be lifted more than 0.5m higher than the obstacle.       24. When the crane is running without load, the hook must be raised above the height of more than one person.       25. It is forbidden to lift heavy objects over the head, and no one is allowed to work under the heavy objects.       26. It is forbidden to transport or lift personnel with crane spreaders.       27. It is forbidden to store inflammable (such as kerosene, gasoline, etc.) and explosive materials on the crane.       28. It is forbidden to throw anything from the crane to the ground.       29. Under normal circumstances, limit switches are not allowed to be used for parking.       30. Do not open the switch and junction box before cutting off. It is strictly forbidden to use the emergency stop device to interrupt the normal operation.

  • How to check the safety of vehicles?

          Shenghang Special Purpose Vehicle Manufacturing Co., Ltd. specializes in the production of series cranes such as crane shs3604, crane shs2004 and crane shs3004. Today, I'd like to remind you that the safety of the vehicle must be checked before departure.       1、 The key points of the round the car inspection method       1. Starting from the front of the vehicle, check whether the license plate is defaced and detached. Now, we will strictly investigate the license plate related problems. If we do not install and use the license plate according to the regulations or deliberately deface and block the license plate due to our carelessness, we will be charged 12 points and lead to direct degradation. That is a serious loss is not worth the gain. Trailer license plate and magnification number also need to be checked to see if they are complete and clear.       2. Check the lights to see if a series of lamps and lanterns, such as the high and low beam of the headlamp, the turn signal lamp, the emergency lamp, the front and rear anti fog lamps, are in good condition. If there is any stain, you need to clean them.       3. Check the tire to see if the tire and spare tire are short of air and if the screw of the tire is loose; If there are stones and other debris stuck in the tire texture, it also needs to be cleaned up.       4. Check the wiper to see if the wiper blade works normally and if there is water in the windshield spout.       5. Check the oil-water separator for moisture and impurities; Pull the water discharge switch of the air reservoir to discharge the accumulated water; By the way, check if all the oil filled caps are loose.       6. Take a look at the front of the car and the whole chassis to see if they fall off and all kinds of connecting pipes fall off, and check whether there is oil leakage in the hydraulic cylinder of the rear axle transmission.       7. The saddle of the tractor is a must for the semi-trailer driver to check whether the traction pin is in place and whether the locking mechanism is reliable.       If the vehicle is engaged in logistics industry, it is necessary to check whether the container is closed firmly and whether the seal or lock is complete; Whether the tarpaulin is bound firmly, whether there is any excess thread exposed, and if there is any, the binding thread needs to be collected; Check all kinds of emergency equipment, whether there are fire extinguishers, triangle warning signs, triangle wood and other emergency supplies on the car. It would be better to bring an orange reflective vest.       Instrument inspection before departure       Enter the cab after the walk around inspection under the vehicle. Before starting the vehicle, we also need to pay attention to:       1. Observe whether the rearview mirror is clean and adjust the mirror angle.       2. Observe the instrument display to see if the oil, fuel, voltage, air pressure and other instruments are normal, especially pay attention to whether there is a fault light alarm. If there is a red fault light alarm, you need to manually remove the fault, do not take the car sick.       3. Shake the steering wheel, feel whether the clearance and rotation are normal, and press the horn to see whether it works normally.       4. It is particularly important to check the brake system. In routine inspection, you can turn on the brake air pressure enough first, and then listen to it to see if there is any air leakage after flameout; You can also step on and hold the brake pedal, listen to the whole brake pipeline in the braking state leakage.
