Why do owners and operators need to re rating the truck after modification?

1. The attachment reduces the lifting capacity
When a forklift is manufactured to its specifications, the lifting capacity needs to be carefully calculated and specified by the manufacturer (eg 2T).

The main reason for the reduced load capacity of the forklift is when installing the accessories.

Simply put, the total weight of the attachment is subtracted from the overall lifting capacity of the unit (for example, if the 2T forklift is fitted with a 200kg accessory, the derating capacity is reduced to only about 1.8T, as long as the load center of the unit and the accessories are the same) .

When installing any new accessories, the forklift must be re-rated by the manufacturer according to its specific formulation, depending on the new specifications of the equipment.



Once the equipment is properly re-rated, the manufacturer must issue a new nameplate with updated lifting capabilities and accessory specifications.

All forklifts need to be re-rated after the manufacturer has installed the accessories



2. Properties that affect the load
Since there are a variety of forklifts on the market, each unit has its own capacity, lift height and load center specifications.

Lifting height and load center are two factors that can greatly affect unit lifting capacity, as well as stability and safety.

Usually, when the load is correctly positioned in the center, the load center of the forklift is about 600mm; the weight is evenly distributed on the Tyne and the carriage.

This provides maximum stability during the lifting movement.

In addition to properly positioning the load at the load center, the lift height plays a crucial role in safety and stability.

The higher the load is lifted, the more unstable it becomes. Typically, each forklift has a reduced lift capacity when it is raised to its maximum height.

When lifting to maximum height, the operator must only raise the correct positioning and rated load to ensure load stability and reduce the risk of operator/pedestal injury or infrastructure, forklift or cargo being lifted.

Forklift load center and lifting height are important considerations when lifting loads


3. Mobile large load
When lifting, you should not only carefully consider the weight of the load, but also the size. If the load is too large, it will affect its balance.

The operator should carefully calculate the load balance point as this may not always be central.

When lifting an excessive load, it is usually recommended to reduce the total load weight, so do not exceed the unit lifting capacity.

If the load is not properly installed on the par, you may need to lift the attachment (such as the spreader bar) to properly support the load.

It may be necessary to install an attachment such as a spreader lever to handle large loads of movement

In summary, it is essential to re-evaluate all future modifications of the truck so the operator is fully aware of the new lift capacity available on the equipment.
