Attachment
A device fitted to a forklift to extend its handling functions, such as side shift, fork positioning, clamping or rotation, with effects on residual capacity.
Definition
Forklift attachments adapt handling to particular goods. Side shifters improve alignment, fork positioners suit different pallets, clamps handle goods directly, rotators support tipping and push-pull units use slip sheets. Attachment mass and forward thickness change load moments and stability, so the truck-and-attachment combination needs its own verified capacity.
Common Types
Side shift reduces chassis repositioning, while hydraulic fork spacing avoids manual adjustment. Clamps can remove the need for pallets for suitable rolls, drums or appliances. Rotators turn loads; push-pull units handle slip sheets. Begin with material and process requirements rather than selecting features first.
Residual Capacity
Attachment weight is additional front-end load, and thickness pushes the load centre forward. Both reduce allowable payload, sometimes substantially. Use the approved capacity chart and identification for the installed combination, rather than the original bare-truck rating.
Hydraulics and Controls
Many attachments need extra hydraulic circuits, suitable flow and pressure and properly integrated controls. Hoses must accommodate full mast movement without pinching or abrasion. Qualified installation and clear controls reduce leaks, damage and unintended actions.
Safety
Clamps depend on correct force and load retention, including the designed response to pressure loss. Rotation moves the centre of gravity; side shifting changes lateral balance. Check mounting and locks before use. Changed front dimensions and visibility require operator familiarization.
Selection and Records
Assess the goods, choose the handling method and verify remaining capacity together with the manufacturer. Record each vehicle's approved configuration and maintain mounts, seals and moving parts. Provide attachment-specific training because the hazards differ substantially between types.
Frequently Asked Questions
Can I keep using the original forklift capacity?
No. Use the verified residual capacity and chart for the installed attachment, accounting for its mass and load-centre displacement.
What must be checked during installation?
Vehicle compatibility, approved capacity, hydraulic flow and pressure, hose routing, controls, secure mounting and specific operator training.
