The IAH converts a forklift into a mobile crane for occasional lifting, and its advantage over a fixed hook is that it sits anywhere along the fork blade — so you position the hook to suit the load rather than the other way round. Seven capacities from 1000kg to 5000kg and a light 16 to 29kg body make it practical to fit and remove between pallet duties.
Key Features
- Fully adjustable positioning — slides along the fork blade (except taper) to achieve multiple lifting positions
- Complete lifting kit — supplied with single swivel hook and bow shackle as standard
- Wide capacity range — seven models from 1000kg to 5000kg to suit any application
- Secure attachment — zinc plated twist screws lock the hook safely onto the fork blade
- High-visibility finish — painted bright orange for on-site safety compliance

More About This Product
The Invicta Adjustable Fork Mounted Hook (Model IAH) provides a quick and economical method of lifting and positioning unpalletised loads using your existing forklift truck. Multiple lifting positions can be achieved by correctly positioning the attachment along the fork blade, effectively converting your forklift into a mobile crane for occasional lifting duties. Available in seven capacities from 1000kg to 5000kg, the IAH is the standard-duty version suited to a wide range of industrial and construction applications. Maximum fork section 150 x 50mm at 355mm centres. Manufactured in Leeds by Invicta Forks & Attachments, the UK's largest mechanical forklift attachment manufacturer.
Suitable Applications
The IAH is suited to construction sites, warehouses, manufacturing plants, engineering workshops and distribution centres where occasional lifting of unpalletised loads is required. Common uses include lifting motors, pumps, steel fabrications, machinery, precast concrete elements and other items that cannot be moved on a standard pallet.
A hook suspends the load, making the work a lifting operation. For more reach see jibs; for loads that can be carried on the tines, fork extensions.
How to Use the Adjustable Fork Mounted Hook
- Drive forks into fork pockets ensuring thumb screws are suitably retracted.
- Locate the attachment to the required position along the blade of the fork.
- Tighten thumb screws at the desired position ensuring they are adequately tightened.
- Attach your load to the swivel hook and shackle.
- The attachment is now ready for use.
Warning:
Always make sure only vertical lifts are made — do not make diagonal lifts. The mast must remain vertical at all times. Do not exceed the safe working load.
Safety Information
- Ensure the operator is fully conversant with the attachment before use.
- Ensure both the truck and attachment are capable of handling the intended load.
- Ensure the shackle pin is adequately tightened before each use.
- Do not tighten the thumb screws onto the taper of the blade.
- Do not shock load the attachment under any circumstances.
Inspection and Maintenance
Inspect weekly with particular attention to all weld points, wear and distortion of fork pockets and thumb screws, and condition of the swivel hook, safety latch and shackle. Certified for six months from manufacture — re-test or competent person inspection required thereafter.
Frequently Asked Questions
Q: What fork size does the IAH fit?
The IAH is designed to slide onto standard fork blades. Check the maximum fork section stated for your model before ordering, and ensure the heel pin can be fitted directly behind the fork heel.
Q: Is the IAH LOLER compliant?
Yes. It is manufactured in the UK by Invicta Forks & Attachments and supplied with a test certificate and EC Declaration of Conformity where applicable. Thorough examination by a competent person is required every six months after initial certification.
Q: How is the lifting position adjusted?
The attachment is slid along the fork blade to the required position and secured before lifting. This lets you set the hook to suit the load rather than working to a fixed centre.
Q: Does moving the hook change the rated capacity?
The attachment's rated capacity is stated per model, but moving the load further from the carriage reduces what the truck itself can lift. Always confirm the forklift's rated capacity at the resulting load centre.
Q: Which model do I need?
Models run IAH-1.0 through IAH-5.0, rated 1000kg to 5000kg, weighing 16kg to 29kg with a 125mm centre of gravity throughout. Select on the heaviest load you intend to lift, allowing margin for the lifting accessories.
Q: Should I choose the IAH or the IAH-E?
The IAH covers seven capacities to 5000kg. The IAH-E is a compact economy version rated to 2000kg for sites where storage and transport space are limited. Choose the IAH where capacity or range matters.
Q: Can it be left fitted to the forks?
It can remain fitted between lifts, but it should be removed for normal pallet handling and inspected before each lifting use. Check pin engagement and the hook safety latch every time.
