A forklift truck attachment is any device or add-on fitted to a truck's forks or carriage designed to modify or enhance the machine's functionality, making it suitable for more than just moving standard pallets. With the right attachments, a standard forklift can be transformed into a versatile tool capable of handling specialized tasks across a wide range of industries, from warehousing and construction to agriculture and recycling.
Most Common Forklift Attachments
Side Shifters
A side shifter allows an operator to move the forks 4 to 6 inches left or right without repositioning the entire truck. It uses two-way hydraulic cylinders to provide off-center movement that adds precision to stacking operations and reduces the need for precise truck positioning. Side shifters are particularly beneficial in narrow aisle environments and are now one of the most common attachments found on forklifts.
Fork Positioners
Fork positioners allow operators to quickly and accurately adjust fork spacing to fit different pallet sizes without leaving their seats. This hydraulically-powered alternative to manual fork repositioning is especially useful when load widths change frequently, increasing productivity and reducing pallet damage.
Fork Extensions
Fork extensions slide over existing forks to enable operators to lift and move larger, longer items. They prevent the need to unload pallet contents to smaller vessels, reducing double handling and saving time. However, special care must be taken to not extend the overall load center too far, or tip-over risk increases.
Clamps
Clamps are among the most popular forklift attachments and are available in numerous configurations. Common types include:
Carton Clamps: Use large, flat side-plates to securely grip uniform, square loads, eliminating the need for pallets and saving up to 10% of usable storage space
Paper Roll Clamps: Feature curved arms designed specifically for handling rolled or round loads like paper rolls or drums
Drum Clamps: Designed to lift and transport drums safely
Bale Clamps: Handle non-palletized bales of paper, cotton, textiles, and other materials
Rotators
Rotators add 360° revolving motion to truck forks in both directions. This hydraulically-driven mechanism is capable of rotating loads a full 360 degrees for dumping or inversion. Rotators are commonly used in waste management, recycling, food processing, and agriculture.
Push/Pull Attachments
Push/pull attachments are designed to move goods that are not placed on pallets. The concept is to enable the truck to handle slip-sheet-stacked loads; the device slips under the load and pushes it off, making it useful for car or van loading. The slip-sheet retainer option allows the sheets of paper, carton, or plastic placed below the load to be reused.
Booms and Jibs
Forklift booms and jibs extend the forklift's reach for lifting suspended loads, effectively converting a forklift into a mobile crane. Carpet poles or rug poles are slim, forward-facing arms that fit through the center of rolls and coiled goods. Adjustable jib booms can extend from approximately 6'9" to 12' with multiple lock-in positions.
Specialty Forks
Beyond standard forks, several specialty options exist:
Weigh forks: Allow operators to lift and move objects while weighing them, often equipped with technology for data tracking
Folding forks: Fold up to help operators navigate tight or awkward spaces like corners, freight elevators, or entryways
Inverted forks: Also called upside-down forks, help lift objects to greater heights
Selecting the Right Attachment
When choosing a forklift attachment, consider these questions:
How do you want to handle the load?
What is the weight of the load?
How high do you need to lift the load?
How many hydraulic functions will be required?
Will the attachment be required only part time?
How many operators will need to be trained?
Attachments can be standard off-the-shelf models or custom-made designs for specific applications.
Safety and Compliance Requirements
Manufacturer Approval is Mandatory
OSHA regulation 29 CFR 1910.178(a)(4) requires that any modification affecting capacity and safe operation must have the manufacturer's written approval. Modifications such as drilling into the overhead guard, switching tire types, using different forks, or swapping counterweights all require written permission. If the manufacturer is out of business or does not respond, written approval from a Qualified Registered Professional Engineer is acceptable.
Updated Capacity Plate Required
Forklifts with aftermarket attachments must be marked to reflect the combined weight at maximum elevation. Nameplates and other markings must remain legible at all times. OSHA has cited employers for failing to update capacity plates after adding attachments, exposing employees to rollover hazards.
Load Capacity Reduction
Attachments almost always affect the rated capacity of the truck. Adding an attachment shifts the center of gravity forward, reducing overall capacity and increasing tip-over risk if not properly accounted for. The weight of the attachment also reduces the forklift's net lifting capacity.
The bottom line: Forklift attachments dramatically expand the capabilities of standard lift trucks, allowing them to handle specialized loads ranging from paper rolls and appliances to bulk materials and long timber. Side shifters, fork positioners, clamps, rotators, push/pull systems, booms, and specialty forks all transform a standard forklift into a versatile tool. However, every attachment changes the forklift's center of gravity and lifting capacity. Manufacturer approval is required for modifications, capacity plates must be updated, and operators must be properly trained. When properly selected and used, forklift attachments can significantly improve productivity, reduce product damage, and eliminate the need for specialized equipment.
