On July 11, a reporter learned from the Ningxia Hui Autonomous Region Economic and Information Committee that Dalian Jinzhou Heavy Machinery Co., Ltd. successfully manufactured the world's first super-large Fischer-Tropsch synthesis reactor for Shenhua Ningmei Group at the Ningdong Energy Chemical Base. This milestone marks a significant breakthrough in China's coal chemical industry, filling a long-standing gap in the production of large-scale coal chemical equipment and ending the country's reliance on imported super-large coal chemical reactors.
The "Fischer-Tropsch Synthesis Reactor" is one of 15 key demonstration projects under the National Development and Reform Commission’s "Twelfth Five-Year Plan." It serves as the core component of Shenhua Ningmei Group’s 4 million tons/year indirect coal-to-oil facility. The reactor weighs 2,200 tons, has a diameter of 9.6 meters, and is 61.5 meters in length, with an annual production capacity of 4 million tons.
In August 2012, Dalian Jinzhou secured a 640 million yuan order from Shenhua Group, which included four Fischer-Tropsch reactors. Each unit significantly reduced costs compared to previous foreign imports by over 100 million yuan. Due to its massive size—being extremely heavy, tall, and long—it could not be transported via conventional roadways. To address this challenge, Dalian Jinzhou set up a large-scale manufacturing plant within Shenhua Group’s facility at the Ningdong Energy and Chemical Industry Base, investing 85 million yuan to equip nearly 500 sets of specialized machinery.
This project not only showcases China's growing technological capabilities but also highlights the country's increasing self-reliance in advanced industrial equipment. The successful local production of such critical infrastructure underscores the importance of domestic innovation in energy and chemical sectors, paving the way for future advancements in large-scale industrial manufacturing.
In the automotive and off - road sectors, heavy duty winches are crucial for large vehicles like full - size trucks. Models from WARN Industries, such as their heavyweight series, can pull over 16,000 lbs. They feature heavy - duty carrier plates to manage the significant gear train stress during the recovery of large loads. This makes them perfect for extracting vehicles stuck in deep mud, snow, or on challenging terrains.
Industrial settings also rely on heavy duty winches. For instance, in construction, they are used to move large building materials or machinery. In mining, these winches can haul heavy carts or equipment. They typically have high - torque motors, whether electric or hydraulic, to generate the necessary power. Electric heavy duty winches might have powerful motors that can draw substantial current from a suitable power source, while hydraulic ones use pressurized fluid for operation, often providing even greater pulling capacities.
The cables or ropes used in heavy duty winches are also of high - quality. Steel cables are common due to their durability and ability to withstand abrasion in harsh environments. However, synthetic ropes are becoming increasingly popular. They offer high strength - to - weight ratios, are lighter to handle, and are safer in case of breakage as they have less stored energy compared to steel cables.
Safety features are integral to heavy duty winches. Many are equipped with automatic braking systems to prevent the load from slipping when the winch stops operating. Overload protection mechanisms are also frequently included. If the load exceeds the winch's rated capacity, these systems can either cut off power to the motor or engage additional braking to safeguard the winch and prevent accidents.
A heavy duty winch is engineered to handle the most demanding tasks, designed for applications where substantial pulling force is required. These winches are built tough, often with robust steel frames that can endure extreme stress.
