Forklift attachments can transform a standard forklift into a highly specialised material handling machine. However, for those new to the industry, the terminology can feel overwhelming. From sideshifts to load centres, understanding the language used around forklift attachments is the first step to choosing the right solution for your operation. This beginner’s guide breaks down the most common terms you’ll encounter and explains what they really mean.

Forklift Attachment

A forklift attachment is any device mounted onto the forklift carriage that extends its functionality beyond standard forks. Attachments allow forklifts to handle different types of loads such as pallets, drums, bales, cartons or long products. Common attachments include fork positioners, sideshifts, clamps, rotators and telescopic forks.

Carriage

The carriage is the plate at the front of the forklift mast to which forks or attachments are mounted. Attachments must be compatible with the forklift’s carriage class (such as Class 2, 3 or 4), which is based on forklift capacity and fork dimensions. Ensuring carriage compatibility is critical for safe operation.

Sideshift

A sideshift allows the attachment (and load) to move left and right without repositioning the entire forklift. This improves accuracy when placing loads into racking or tight spaces and is one of the most common and widely used forklift attachments.

Fork Positioner

A fork positioner enables the operator to hydraulically adjust the distance between forks from the cab. This eliminates the need for manual fork adjustment, saving time, improving safety, and increasing productivity, especially in operations handling varying pallet sizes.

Load Centre

The load centre refers to the horizontal distance from the face of the forks or attachment to the centre of gravity of the load. Attachments often increase the load centre, which can reduce the forklift’s rated capacity. Understanding load centre is essential when selecting an attachment to ensure the forklift can safely lift the intended loads.

Rated Capacity and Data Plate

The rated capacity is the maximum weight a forklift can safely lift at a specified load centre and height. When an attachment is fitted, the forklift’s capacity usually changes. Under UK regulations, forklifts must have an updated data plate showing the revised capacity with the attachment fitted.

Clamp Attachments

Clamp attachments are used to handle loads without the need for pallets. Examples include carton clamps, bale clamps and paper roll clamps. These attachments grip loads from the sides using hydraulic pressure and are commonly used in manufacturing, recycling, food and distribution sectors.

Rotator

A rotator allows loads to be rotated, typically 180 or 360 degrees. Rotators are widely used in recycling, waste handling and food production, where loads need to be tipped or inverted safely and efficiently.

Telescopic Forks

Telescopic forks, also known as extendable forks, can slide forward to reach double-deep pallets or long loads. They are ideal for high-density storage environments and help maximise warehouse space.

Hydraulic Functions

Most forklift attachments rely on hydraulic functions to operate. Some attachments require additional hydraulic valves or pipework, which should always be specified and installed correctly.

Why Terminology Matters

Understanding forklift attachment terminology enables UK businesses to make informed decisions, enhance safety, and remain compliant with regulations. With the right knowledge, choosing the correct attachment becomes far simpler and far more effective.
