A limiter for a Tower Crane is a safety device that is installed to prevent the crane from operating beyond its maximum load capacity or from moving beyond its designated working area. It typically consists of sensors, control systems, and alarms to ensure safe operation.

According to the reporter's understanding, the total investment of the project is about 3 billion yuan, and construction of air separation, coal gasification, gas compression, sewage treatment, ammonia synthesis and other technological units. After the project is implemented, it will not only stabilize production, but also greatly increase the output of synthetic ammonia. It will also create conditions for further lengthening the product chain and strengthening the company's strength. At the same time, the company will use the existing coal chemical plant syngas, grafted construction of ethylene glycol project, to achieve "a two-tailed", vigorously develop the coal chemical industry, and cultivate new economic growth points.
The ammonia and urea plant of Zhongyuan Dahua is the 18th set of energy-saving large-scale fertilizer production equipment imported from China. With natural gas as the main raw material, the annual natural gas demand is approximately 400 million cubic meters. Since the middle and late 1990s, the amount of annual gas supply in the Central Plains Dahua has been decreasing year by year. By 2008, the natural gas supply in the Central Plains Dahua was only 210 million cubic meters, and the average installation can only maintain a 50% load operation. Insufficiency has become a bottleneck problem that restricts the development of the Central Plains.
Since 2008, in order to change the shortage of natural gas supply, the company has opened up multiple new sources of gas, from a single supply of gas in the Zhongyuan Oilfield to a joint supply of gas by the Sinopec North China Bureau, PetroChina, and Zhongyuan Oilfields. The multi-channel gas supply pattern has taken shape. Accumulated annual gas supply of 298 million cubic meters.
Although the amount of gas has increased, the cadres and workers in Central Plains Dahua are not happy. In 2009, the gas price of natural gas purchased by Zhongyuan Dahua from the external market was close to the market price, coupled with high pipeline transportation costs, the company spent more than 200 million yuan for the entire year. Moreover, the price of natural gas may still rise further. Therefore, from the second half of 2009, Zhongyuan Dahua began to plan the transformation of raw gas routes into coal projects.
As Zhongyuan Dahua has already joined Henan Coal Chemical Group, the Yongco Company, Jiaozuo Coal Company and Hebi Coal Company under the Group can all provide sufficient raw coal for Zhongyuan Dahua.
According to the person in charge of Henan Zhonghua Dahua Chemical Co., Ltd., with the warming of the weather, the shortage of natural gas has eased, and 80% of the company's gas consumption can already be satisfied. However, judging from the situation in recent years, the shortage of natural gas will be a long-term trend. Therefore, the company is still stepping up the demonstration and trying to implement the raw material route reconstruction project as soon as possible.
The load limiter is designed to monitor the load being lifted by the crane and automatically stop the crane's movement if the load exceeds the specified limit. It helps prevent overloading, which can lead to structural failure or accidents.
The radius limiter is used to restrict the crane's movement within a specific working area. It ensures that the crane does not extend beyond its designated radius, preventing it from colliding with nearby structures or obstacles.
Both types of limiters are essential safety features in tower cranes to protect workers, equipment, and the surrounding environment. They help ensure that the tower crane operates within its safe working limits and minimize the risk of accidents or damage.
Central Plains Dahua wants to change coal to break the bottleneck
The reporter learned from Henan Zhonghua Dahua Chemical Co., Ltd. on February 26th that the preliminary design plan for the raw material route transformation of the Dahua Chemical Fertilizer Plant in Zhongyuan is undergoing exchange demonstration. If the plan is implemented, the Zhongyuan Dahua Fertilizer Plant will use coal as raw material.
