The world's largest hydraulic duplex crane was born

On July 12, the dynamic test of a 6400-ton hydraulic compound crane jointly developed by Sinochem Second Construction Group, Zhongke Synthetic Oil Technology Co., Ltd. and Taiyuan Heavy Industry Co., Ltd. was successfully completed in Sinochem II Construction Machinery Construction Co., Ltd. . This marks the birth of the world's largest hydraulic duplex crane.

According to reports, the crane is a new type of super-excess lifting equipment with a lifting capacity of up to 6,400 tons, a maximum lifting height of 120 meters and a lifting speed of 6 meters per hour. The crane can be divided into two single masts, each of which can weigh up to 3,200 tons and has a maximum lifting height of 120 meters. It can also be attached to existing building frame lifting equipment. The crane lifting frame, sliding and lifting equipment are controlled by full hydraulic automation system, and the localization rate reaches 100%. The crane is easy to assemble on site and flexible in transition. Compared with the large crawler cranes that have been used in the past, it has many advantages such as good lifting performance, low cost, good interchangeability and multi-working conditions, which can greatly shorten the coal chemical industry. Construction period.

In recent years, with the continuous expansion of the scale of China's petrochemical and coal chemical plants, the quality, diameter and height of single equipment have been continuously updated. The quality of single-piece containers has reached 3,000 tons, and it has a larger scale. The development trend, lifting and hoisting of equipment has become a major problem in engineering construction. After analyzing the status quo of large-scale hoisting cranes at home and abroad, Sinochem II decided to develop a 6400-ton hydraulic duplex crane. On July 24, 2011, Sinochem Erjian took the lead in launching a 6400-ton hydraulic duplex crane R&D project with Zhongke Synthetic Oil and Taiyuan Heavy Industry.

Bulk Blending Fertilizer (BB Fertilizer/Mixture of Fertilizer) is a kind of compound granular fertilizer mixed by several single fertilizers or compound fertilizers according to certain proportion. It has characters of granule uniformity, less water, moderate  granule intensity, no agglomeration, easy to use and low cost.

The formulation (N,P,K content) of BB Fertilizer can be flexibly changed according to the crop`s nutrition requirement, local soil fertility, crops growing levels and other conditions, therefore BB Fertilizer is more scientific and targeted especially for balance fertilization.

High-phosphorus fertilizers refer to fertilizers in which phosphorus is higher than nitrogen and potassium.
