Double-deep stacking is quickly becoming a standard choice for high-throughput operations. It can increase the warehouse capacity by 30% when compared to the single-deep operations. Also, the double-deep stacking maximizes the space usage, improves the storage density and reduces the operating costs. There are two types of forklifts which are used for double-deep stacking: telescopic and pantograph forklift. These two models are capable to reach almost twice as the normal forklifts, which means the racking can be doubled. A telescopic or pantograph forklift can access very narrow double-deep storage areas, such as an aisle.
Pantograph Forklift
The double-deep stacking is ideal for both dry and cold store facilities for storing multiple pallets quickly and efficiently. The entire procedure can be performed either with a telescopic or pantograph forklift with hydraulic forks. The telescopic forklift is preferred in Europe, while the pantograph forklift is used all around the world. However, the telescopic forklift offers more advantages than the pantograph forklift. Some unique advantages of the telescopic forklifts are the following ones:
- Simpler design and less weight;
- Lower up-front cost;
- Higher load capacity;
- Improved workplace safety and faster operation;
- Lower maintenance costs;
- Simple set-up and removal;
- More flexibility and versatility;
The main advantage of the pantograph forklift is its capability to operate in tight and narrow areas. Most forklifts used for double-deep stacking use thin forks for increased versatility on the job site. They are designed to be capable to handle all types of pallets with low profile side openings. And with the introduction of single-range telescopic forks, the telescopic forklifts are almost equivalent to the pantograph forklift models.
Telescopic Forklift
Telescopic forks can be mounted on any forklift truck. The lift truck mast doesn’t need to be changed when adding the telescopic forks, only if the force-distance moment remains the same. The telescopic forks boost the versatility of any forklift. By converting the conventional forklift trucks into double-deep forklifts, the telescopic forks allow trucks and trailers to be loaded and unloaded from one side only.
As a short conclusion, the operators can reduce the costs significantly by using either telescopic or pantograph forklift. Which model to choose will depend on their needs.
