Storage warehouse stacker cranes are cranes that operate in the narrow aisles of high level racks, which can greatly improve the area and space utilization of the warehouse and are the main equipment for automated warehouses. At present in much large storage warehouse, we can see the storage warehouse stacker crane figure. In order to deepen your knowledge of the automated storage warehouse stacker crane, this article will introduce you to the characteristics of the automated storage warehouse stacker crane.
The stacker crane is the core equipment of the logistics system integration project and is the main lifting and transport equipment in the automated storage warehouse. It is a special lifting machine equipment developed with automated storage warehouse. This equipment is used in warehouses up to 40 m. Most of them are between 10 and 25 m. The main use of the stacker crane is to shuttle back and forth between the aisles of the automated warehouse. The goods located at the entrance of the aisles are deposited into the pallets. Or the goods are taken out of the compartment and transported to the aisle entrance. This equipment can only be operated within the warehouse. Additional equipment is required to get the goods in and out of the warehouse.
The early stacker crane was a gantry (column) suspended from the lifting trolley of the overhead crane, using the up and down movement of the forks on the column and the rotational movement of the column to move the goods, usually called bridge stacker crane. In 1960 or so in the United States appeared the aisle type stacker crane. This type of stacker uses ground rails to prevent tipping. Subsequently, with the development of computer control technology and automated automated warehouse, stacker cranes have become more and more widely used, with better technical performance and higher heights. Today, stacker cranes can reach heights of up to 40 meters. In fact, the height of stacker cranes can be even higher, if not limited by the construction and cost of the warehouse.
The stacker cranes reduce the workload of the workers. It increases the utilization and turnover of the warehouse. It has the following characteristics.
1. The stacker crane is special equipment for the automated warehouse, with high handling access speed, which can be completed in a short time in and out of the warehouse operation.
2. The stacker crane is small in size and can be operated in aisles of small width, and is also suitable for high level racking operations.
3. The stacker crane can be controlled remotely and the operation process does not require manual intervention, which is highly automated and easy to manage.
4. Stacker cranes have high reliability and good stability when working.
5. Stacker cranes have special pick-up devices, such as forks. Manipulator, etc.
6. The electric control system of the stacker crane is fast, stable and accurate. The electrical control system of the stacker crane has the characteristics of being fast, stable and accurate to ensure that it can quickly; accurately; safe remove and deposit goods.
7. The stacker crane has a series of chain protection measures, as the workplace is narrow. A little inaccuracy will destroy the warehouse, so the stacker crane is equipped with a series of mechanical and electrical protection measures.
The impact of stacker cranes on the automated storage warehouse is mainly as follows.
1. High operational efficiency
Stacking cranes are special equipment for automated warehouses, with high handling speed and goods access speed, can be completed in a short period of time in and out of the warehouse operations, the highest operating speed of stacking cranes can reach 500m / min.
2. Improving warehouse utilization
Stacking cranes are small in size and can run in aisles with small widths, and are also suitable for high level racking operations, which can improve the utilization rate of the warehouse.
3. High degree of automation
The stacking crane can be controlled remotely and the operation process does not require manual intervention, so it is highly automated and easy to manage.
4. Good stability
Stacking cranes have high reliability and good stability when working.
Development status of stacker cranes in automated warehouse
Stacker crane is the core equipment in the automated warehouse racking system, the current market demand for mainstream stacker crane products has basically achieved localization, manufacturers in the stacker crane products widely used infrared, laser, wireless, servo drive, contactless power supply and even RFID technology, stacker crane using the basic technology, key components and supporting parts and internationally renowned manufacturers have been very close to the general series of technical specifications and The technical specifications and technical parameters of the universal series are not very different from those of foreign products.
Most china manufacturers are basically capable of manufacturing stacker cranes with a height of up to 24 meters, a load capacity of up to 1000 kg and a walking speed of up to 180 m/min, and a single unit can meet the demand for 45-50 pallets/hour access capacity. High-speed stacker cranes with a speed of more than 300 m/min have only a few manufacturers in China who have completed their technical research.
At present, the development of China’s logistics industry is still lagging behind, the small scale of third party logistics services, the lack of logistics infrastructure capacity and other bottlenecks make China’s logistics costs much higher than those of the United States. Through the international common measure of logistics costs (logistics costs as a proportion of GDP) comparison found that the proportion of logistics costs in the United States to GDP is about 8%, while China reached 18%. As the logistics automation equipment to promote the logistics intermediate link, its equipment market transformation and upgrading, including automated warehouse stacker crane equipment products. Equipment manufacturing enterprises to increase market development efforts, research and development of high-end products, upgrade the service model, the development of emerging markets.
With the rapid development of retail chains, e-commerce, medicine, tobacco, express and other industries, the number of logistics distribution centers has increased significantly, the demand for automated warehouses, automatic sorting systems, automatic identification systems, handheld terminals and equipment system integration is strong, logistics equipment systematization, automation, intelligence, green energy saving, technology specialization, product industrialization trend is obvious.
In terms of the current state of China’s logistics industry, it has yet to produce a market-based giant like UPS. But for China’s small, scattered and disorganized logistics companies, it may be possible to create a “bottom system”. In the future, the intelligent logistics network will exist as such a “bottom system”, on which other logistics companies can use system data to optimize their networks, improve efficiency or adjust their business models.
The country’s economy continues to improve and the high demand for automated storage warehouses for tobacco, pharmaceuticals, machinery and other industries continue to grow rapidly, the future of automated storage warehouse is facing a large market demand. In the pharmaceutical industry, for example, according to the National Bureau of Statistics data show that, as of 2012, China’s industrial output value of more than 20 million enterprises in the number of 6075, calculated at 10% of the demand, the pharmaceutical industry demand for automated storage warehouse has 607 sets, and the current retention of fewer than 200 sets, the market prospects are considerable. Automatic warehouse market value has exceeded 17 billion yuan, according to the China Logistics Technology Association Information Center research, the next few years of automated warehousing market demand will have an annual growth of 17%, is expected to 2025, the market size of automated storage warehouse will exceed 65 billion yuan.
In summary, we can easily see that the current China automated warehouse stacker has made great progress, but compared to foreign countries there is still a gap, but in the broad prospects of the market and government support, the future development prospects of the China automated warehouse stacker is still bright and good.
