Attachments and Instruments: How to Adapt Your HELI Forklift for Special Loads Without Losing Safety

In the universe of industrial logistics, not all goods are transported on standardized pallets. Industries such as paper, recycling, agrochemicals, food, and steel daily handle materials with complex geometries: paper rolls, cotton bales, chemical drums, or sheet metal coils.

Attempting to move this type of load using improvised methods or adapting standard forks without the proper instruments poses a critical risk of material dropping and equipment rollover. To solve these challenges without losing efficiency, the technical solution lies in the integration of hydraulic attachments for forklifts. Below, we analyze the main accessories on the market and the most important technical variable to operate safely: calculating residual capacity.

1. Main Attachments and Their Applications in the Industry

An attachment is a hydraulic mechanism mounted on the forklift's carriage, transforming a conventional machine into a precision tool for specific tasks:

• Side Shifters: They allow the carriage with the forks to move left or right without needing to maneuver the entire machine. It facilitates the perfect alignment of the pallet within the rack, reducing tire wear and accelerating stacking times.

• Fork Positioners: They allow adjusting the opening and closing between the forks hydraulically from the cabin. It is indispensable for plants handling multi-size pallets without the operator having to step down to manually adjust the forks.

• Hydraulic Clamps: Designed with curved or flat arms to hold the load directly through regulated pressure. There are specific clamps for paper rolls, cellulose or recyclable bales, and drum handlers.

• Multi-pallet Handlers (Double pallet): Allows picking up two or four pallets simultaneously, doubling the dispatch volume per cycle in high-intensity terminals.

2. The Key Concept: Residual Capacity and Load Center

Adding an attachment to a forklift directly alters the physics of the machine. The dead weight of the accessory and the additional distance separating the load from the front of the carriage generate what is known in engineering as a loss of residual capacity.

If a forklift has a nominal capacity of 2,500 kg at a 500 mm load center, installing a paper roll clamp that weighs 400 kg and shifts the center of gravity forward means the machine will no longer be able to safely lift the original 2,500 kg.

⚠️ Operational Safety Principle: Ignoring the recalculation of the residual capacity can cause the equipment to tip forward due to the loss of natural counterweight. Every modification must be backed by an updated load capacity plate in the cabin indicating to the driver the actual maximum weight allowed at different heights.

3. Factory Integration and HELI Hydraulic Compatibility

To avoid pressure losses in the system or overheating of the hydraulic oil, installing attachments requires having the additional control valves (3rd and 4th hydraulic valves) properly integrated from the main distributor.

The HELI forklift fleet offers factory preparation for adding complex instrumentation. By featuring high-fidelity hydraulic components and reinforced chassis, HELI equipment maintains an excellent residual capacity index, ensuring that mounting a side shifter or clamp does not drastically penalize the equipment's lifting capacity.

Conclusion

Customizing your forklift with the correct attachment not only multiplies the plant's versatility but also eradicates dangerous maneuvers and protects the integrity of high-value special loads. Pairing technology with the corresponding engineering calculation is the only way to guarantee 100% safe operations.
