The fork of the stacker is the part that directly carries the cargo. Its type, specifications, and adaptability to the accessories directly determine the handling capacity and safety of the equipment for different forms of cargo, especially pallets of different specifications.Standard forks are usually two parallel steel wishbones, and their key parameters include length, width, thickness, and outer distance (fork width).The length of the fork needs to be ensured to fully support the pallet, which is usually more than 100-150 mm longer than the length of the pallet; the width of the fork needs to match the spacing of the fork inlet of the pallet. Common ones are fixed-width designs suitable for European standard pallets (800mm x 1200mm) or American standard pallets (1000mm x 1200mm), and some models are equipped with forks that can adjust the width manually or electrically to adapt to a variety of pallets.The front end of the fork is usually designed with an upward angle to facilitate insertion into the bottom of the tray.

For standard wooden or plastic pallets, use a matching standard fork.However, when facing special goods such as non-standard pallets, flexible packaging pallets, paper rolls, bins, etc., it is necessary to use various accessories to expand the function of the stacker.Common accessories include: side shifters, which allow the fork to move laterally from left to right as a whole, which facilitates fine-tuning and alignment when the cargo position is not in time, greatly improving the stacking accuracy and efficiency.Clamp arm, used to carry goods without pallets or flexible packaging (such as carton piles).Push-pull device, used to carry goods with sliders at the bottom, without inserting pallets.Rotator, which can rotate the fork and its load, is suitable for stacking or dumping operations at a specific angle.Each accessory is connected to the gantry of the stacker through a mounting frame, and its function may be realized through additional hydraulic pipelines or electrical interfaces.

Choosing suitable forks and attachments for pallets and goods of different specifications is the core of formulating effective handling solutions.When selecting models, enterprises must first analyze in detail the mainstream unit specifications (pallet size, type, and cargo form) of their own goods, and determine the basic fork requirements.If the cargo specifications are single, a standard fork can be used.If the specifications are diverse, priority should be given to models with adjustable fork width or models with standard side shifters to enhance versatility.For special forms of cargo, it is necessary to evaluate the necessity of special accessories. At the same time, it should be noted that the installation of accessories usually reduces the rated lifting weight of the stacker (due to the weight of the accessories and the change of the load center), and may affect the passing height of the vehicle (the height of the door frame is increased).Therefore, this is a project that requires a comprehensive trade-off. The goal is to cover the most important handling needs safely and efficiently with the most reasonable configuration, thereby improving the smoothness and safety of the overall logistics link.
