This is just a starting point; more participation will make things more lively. Haichuan becomes even better with you all; we welcome everyone to engage more in discussions on this forum. Happy May Day! A safe and secure Red May ********************************************* In today’s construction projects, it is necessary to compact the soil in the foundation layers, which means that ramming is essential. For smaller construction projects, small electric rammers are sufficient for compacting the foundations. However, larger construction projects often have strict requirements regarding the condition of the foundations; they must be compacted to a certain degree before they can be considered satisfactory. This leads to specific requirements for the rammers used, and as a result, many different types of rammers have been developed. Today, there are various types of rammers, including frog-type, vibration-type, jumping-type, and hammer-swinging type; moreover, some heavy-duty rammers are extremely powerful. On October 31, 2020, Bobang Heavy Industry in Ningxiang High-Tech Zone, Hunan, produced a truly massive crawler-type dynamic compactor – its ram alone weighed 90 tons, and its boom was 35 meters tall; it was capable of lowering the ram from a height of 20 meters, so one can imagine the force exerted on the ground. This dynamic compactor of the BTM1800 model has been named “War Tiger.” It is reported that Bobang Heavy Industry utilized nearly a hundred patented technologies in the development of this compactor, including its own \"hydraulic and mechanical dual-drive winch system\" technology, which allows it to operate with engines of relatively low displacement while still meeting high-displacement requirements in order to achieve energy savings and emission reduction. Through integrated control of liquid, electrical, and pneumatic systems, it enables functions such as smooth lifting of the hammer, accurate positioning, safe and reliable suspension in mid-air, and secure lowering of the heavy hammer from above. Under high-intensity construction conditions, the enhanced winch and transmission system of the \"Zhanhu\" dynamic compactor enables a single-rope tension more than three times that of compactors of the same class. The machine’s buffering system can eliminate the backward tilting force that occurs during operation, thanks to the combined action of the anti-backward-tilting component and the recoil force buffering component; this also reduces the impact forces generated during operation, thereby extending the service life of the dynamic compactor.
