Industrial businesses and warehouses have various reasons to consider buying either an automatic or a manual stacker crane. These machines are meant to be used for many years and under heavy conditions, which is why proper selection is important. When used correctly, they can greatly increase productivity.
Here is a rundown of some of the most common ones:
Horizontal stacker cranes
These are also called narrow-aisle stacker cranes. They can efficiently place several pallets in narrow spaces. Therefore, they are commonly used in high-density pallet storage systems. They can operate several racks either manually or automatically.
High rack stacker cranes
These stacker cranes are used for vertical storage in tall warehouse facilities. They are made to work with an automatic storage and retrieval system. Their operations are computer-controlled, ensuring accuracy and safety. This makes them effective in increasing warehouse storage capacity.
Double deep stacker cranes
These stacker cranes can handle two pallets simultaneously, one behind the other. This system doubles the pallet storage density in a particular aisle. It also improves the efficiency of pallet handling. These cranes are commonly used in facilities where the stacking of multiple loads is required.
Reach stacker cranes
They are highly flexible container handling equipment because they are able to operate in a stack or transport container trains. Their reach enables them to work with different container sizes. This makes them efficient in marine and intermodal yard operations.
Mobile stacker cranes
As their name states, these stacker cranes are mobile, providing flexibility when stacking. They move from one area of operation to another. These cranes save time when used in multiple or changing tasks. They are smaller cranes mainly used in construction and yard operations.
Stacker cranes in warehousing
Stacker cranes are important for efficient storage in warehouses. They are automated systems responsible for moving materials to and from storage locations. Their accuracy, speed, and ability to work in narrow aisles make them suitable for high-capacity operations. These cranes reduce the cost of labor and increase the efficiency of inventory management in modern warehouses.
Stacker cranes for logistics
In logistics centers, stacker cranes help to speed up the processes of loading and unloading pallets and containers. Their task of optimizing the handling of materials increases the turnaround time. Many distribution centers use them to streamline their operations, as they handle different types of pallets and materials commonly used in transportation.
Stacker cranes for manufacturing
Stackers are used for material handling in manufacturing facilities. They store raw materials and parts in rack systems used for production. Automated stackers improve the just-in-time supply of these elements, which reduces disruptions and increases efficiency. Common sources of stacker crane system demand are industries such as automotive and electronics with high demand for manufacturing.
Stacker cranes in cold storage
Cold storage facilities use stacker cranes for palletized frozen foods, dairy products, and other perishables. These materials need a special rack handling system. Commonly used types are high-bay stacker cranes, as they maximize storage capacity and maintain required low-temperature profiles.
Stacker cranes in retail
Stacker cranes are used in retail operations that handle warehousing of products before distribution to stores. They help to move inventory quickly, leading to lower costs and better management of stock levels. They are particularly valued in large retail chains that have to deal with large volumes of palletized goods.
Stacker cranes for yard operations
Stacker cranes are common in container yards, intermodal facilities, and maritime operations. They handle containers efficiently and provide the necessary mobility for different container sizes.
The durability of stacker cranes is very important because these cranes are constantly used in demanding material handling operations. Key factors that contribute to the durability of these factors include:
One of the most important aspects of durable products is the materials used to make them. Similarly, stacker cranes use high-strength steel to manufacture the major components of the crane. Other materials with a high resistance to wear and fatigue are employed. They include:
The engineering design of stacker cranes keeps durability in mind. The components of the crane are designed to deal with the stresses and loads exerted upon them. Durability is also increased through reinforcement in critical areas that undergo constant movements such as the base, mast, and forks. Advanced simulation technologies are also applied in the design process to identify potential weaknesses before they occur.
The durability of stacker cranes can be attributed to their robust drive systems. Cranes that operate for long hours need drive systems that can bear continuous operation. Both electric and hydraulic drives are used to manufacture these cranes. One of the reasons electric drives are durable is because of their low maintenance requirements. Hydraulic drives are powerful and extremely resistant to the conditions of use.
Frequent maintenance is largely responsible for the durability recorded in stacker cranes. Closed lubrication systems and easy access to components for repairs and checks are some features that reduce maintenance requirements. These reduce wear and tear on critical parts such as mast tracks and forks, which increases the overall durability of the crane.
Continuous testing and adherence to international standards have a role in stacker crane durability. Before releasing a stacker crane into the market, various tests are done to evaluate its endurance. This includes stress tests, fatigue tests, and load tests. The stacker crane is redesigned to improve any durability issues identified in the tests. These standard requirements ensure that the cranes meet minimum requirements for durability in demanding environments.
A stacker crane is a significant investment for a business. There are several factors to look at when purchasing these options. Here are some of them:
Different types of stacker cranes have varying load capacity. A manual stacker, for instance, has a lower load capacity than a high rack automatic stacker crane. Businesses should take into account the average load and maximum load that will be handled. This is to ensure they select an option that will not become overloaded during operation.
Another important consideration is the height and reach of the stacker crane. Different options are available to help increase storage space. The reach of the crane is also important because it will determine how far the stacks can be made. Both parameters must work properly for effective operation.
However, not all businesses require high capacity and extensive reach. Some businesses might need a compact option that can work in small spaces. These options are also ideal for niches where operating in narrow aisles is required. This is because there are high-density pallet storage systems that need narrow aisles.
The fuel type will determine the aspects of the stacker that will be affected the most and, therefore, the maintenance needed. There are electric ones that are cheaper to run and more environmentally friendly. There are also internal combustion fuel cranes that provide higher power but with increased fuel costs and emissions.
There are manual stackers that operate with human power, while others are automatic. The automatic ones are more efficient but also costly. This is the main reason why one must consider the type of operation required in their business before deciding on a type.
The cost of investing in a stacker crane is also an important factor to consider. The kind of features desired will determine how much the stacker will cost. One can find affordable options for basic functions. However, advanced features come with a high price. Although they might be costly, they offer one better efficiency and higher handling capacity.
A. The main advantage of high rack stacker cranes is that they maximize storage density. They do this by combining the height of the storage bay with the proper bay. They improve efficiency by reducing the area of the floor required for storage. Their automated system also makes them efficient because they reduce labor costs while improving accuracy.
A. Yes, there are. Stacker cranes with an internal electric combustion drive are preferred in outdoor applications. They are suitable for heavy loads and offer strong power and performance on inclined surfaces. This makes them ideal for mining industries and endeavors that require high power and tough conditions.
A. Yes, they are suitable. Manual stacker cranes, for instance, are quite popular in this arena. They can be easily operated to move loads with a short spatial duration. These are especially efficient when working on small tasks or in very confined areas.
A. Major maintenance work is done on the mechanical components of the stacker crane. This includes things like lubrication. Regular checks on hydraulic systems, electrical components, and drives are also advised. Other maintenance practices include checking for wear and tear on the stacker crane parts and ensuring that the drives and wheels are clean and well maintained.
