What is the difference between a fork over stacker and a straddle stacker?

When it comes to materials handling equipment, forklifts are an essential part of many industries. However, not all forklifts are created equal. There are various types and configurations available, each with its own set of advantages and specific applications. Two common types are the fork over stacker and the straddle stacker. But what exactly sets them apart? Let's delve into the details and explore the differences between these two types of forklifts.

Fork over stackers, as the name suggests, are designed with forks that extend beyond the front of the vehicle's body. On the other hand, straddle stackers have legs or outriggers that straddle the load, hence the name. Now, let's break down the key differences between these two types of stackers:

1. Load Placement:

- Fork over stackers are primarily used for the transportation of pallets and skids from one place to another. Their design allows the forks to slide under the load, providing stability during transport. It is important to note that fork over stackers can only handle open-bottomed pallets or loads as the forks cannot slide under a closed-bottom pallet. On the other hand, straddle stackers are suitable for handling both open and closed-bottom pallets. The legs or outriggers of the straddle stacker straddle the pallet, providing stability during lifting and transportation.

2. Lifting Capacity:

- Fork over stackers typically have a lower lifting capacity compared to straddle stackers. This is because the weight of the load is concentrated on the forks, which may limit the overall lifting capacity. Straddle stackers, with their wider base and the support of outriggers, offer higher lifting capacities, making them better suited for heavier loads.

3. Clear Width:

- The clear width, or the width between the legs or outriggers, is an important consideration when selecting a stacker. Fork over stackers generally have a fixed clear width, which is determined by the width of the forks. On the other hand, straddle stackers offer adjustable clear widths, allowing them to accommodate different load sizes. This adjustability makes straddle stackers more versatile in handling varying load widths.

4. Turning Radius:

- Another crucial factor to consider is the turning radius of the stacker. Fork over stackers have a larger turning radius compared to straddle stackers. This is mainly due to the protruding forks that limit the maneuverability of the vehicle. Straddle stackers, with their outriggers positioned on the sides, offer a tighter turning radius, making them more agile in narrow aisles and confined spaces.

When choosing between a fork over stacker and a straddle stacker, it is essential to evaluate the specific needs and requirements of your material handling operations. Both types have their own advantages and are suitable for different applications.

In conclusion, the key differences between a fork over stacker and a straddle stacker lie in load placement, lifting capacity, clear width, and turning radius. Fork over stackers are ideal for handling open-bottomed pallets with lower lifting capacities, while straddle stackers offer more versatility, accommodating both open and closed-bottom pallets with higher lifting capacities. The clear width of straddle stackers is adjustable, allowing for different load sizes, and they also provide a tighter turning radius for enhanced maneuverability. Understanding these differences will enable you to make an informed decision and select the right type of stacker for your materials handling needs.
