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

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.

How to Use the Adjustable Fork Mounted Hook

1. Drive forks into fork pockets ensuring thumb screws are suitably retracted.
2. Locate the attachment to the required position along the blade of the fork.
3. Tighten thumb screws at the desired position ensuring they are adequately tightened.
4. Attach your load to the swivel hook and shackle.
5. 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.
