1. Structural Features - Straddle Legs：
The most distinctive feature is the straddle legs, which provide stability and support for the load. The distance between the legs can usually be adjusted to accommodate different pallet widths, making it versatile for various pallet sizes.
- Mast Assembly：Similar to other pallet stackers, it is equipped with a mast that enables the lifting and lowering of the forks. The mast can be single-stage, double-stage, or multi-stage, depending on the required lifting height.
- Forks：The forks are attached to the mast carriage and are used to pick up and hold the pallet. They are available in different lengths and widths to suit different load requirements.
- Operator Platform/Controls：Some straddle stackers have a standing platform for the operator, while others are walk-behind models where the operator walks alongside the machine. The control panel is typically located within easy reach of the operator, allowing for convenient operation of lifting, lowering, and traveling functions.
2. Application Scenarios - Narrow Aisles：Due to its compact design and straddle legs, it is well-suited for operation in narrow aisles of warehouses and storage facilities. The straddle legs allow it to navigate through tight spaces while still being able to handle pallets.
- Low-Level Stacking：It is commonly used for low to medium height stacking operations, typically up to around 5-6 meters. It is ideal for warehouses with medium ceiling heights where high-rise stackers are not necessary.
- Light to Medium Loads：Straddle stackers are generally designed for light to medium load capacities, ranging from around 1 ton to 3 tons. They are suitable for handling a wide range of palletized goods such as boxes, cartons, and small containers.
- Retail and Small Warehouses：Their compact size, maneuverability, and ease of operation make them a popular choice in retail stores, small warehouses, and distribution centers where space is limited and the volume of goods handled is not extremely large.
3. Advantages
- Good Maneuverability：The straddle design and compact body make it easy to maneuver in tight spaces, improving operational efficiency in narrow aisles.
- Versatility：Adjustable straddle legs allow it to handle different pallet sizes, increasing its applicability in various working environments.
- Easy Operation：The control system is simple and intuitive, making it easy for operators to learn and master, reducing training time and costs.
- Cost-Effective：Compared to high-rise stackers and forklifts, straddle stackers are generally more affordable, making them a cost-effective solution for small and medium-sized enterprises with limited budgets.
