Avoid exposing forklift operators to potential danger
Calculate the effect of your
on fork truck capacity
The capacity factor is important to
safety (truck stability and avoiding damage to your truck). You should
also ensure that the truck can do the work you need done.
Morse drum handling forklift attachments tend to move the center
of gravity of the combined truck and load forward. The farther forward
the center of gravity moves on the forklift, the smaller the load weight
must be, and the more likely the fork truck is to tip forward.
With a drum handling forklift attachment in place, fork
truck capacity can be substantially lower than the original rated
- Refer to the correct Operator's Manual for dimensions of
your Morse drum handling forklift attachment. This information is used
to calculate the lost load on your equipment.
- Contact your fork truck dealer or manufacturer for determination of capacity with drum
- If forklift manufacturer is unhelpful or out of
business, OSHA provides the option of hiring a registered professional
engineer to test and approve the addition of a forklift attachment.
Applicable OSHA Regulations:
Modifications and additions which affect capacity and safe operation
shall not be performed by the customer or user without manufacturers
prior written approval. Capacity, operation, and maintenance instruction
plates, tags, or decals shall be changed accordingly.
If the truck is equipped with front-end attachments other than factory
installed attachments, the user shall request that the truck be marked
to identify the attachments and show the approximate weight of the truck
and attachment combination at maximum elevation with load laterally
The user shall see that all nameplates and markings are in place and are
maintained in a legible condition.
OSHA inspector stated that if an employer (truck owner) can't get the
lift truck manufacturer to cooperate, there is an alternative. He said
there is an OSHA letter of interpretation that says "...if the employer
has ... written approval from a qualified Registered Professional
Engineer..." He said the employer should keep such a written approval in
For the complete info, see
letter of interpretation
1910.178(a)(4). The relevant wording in that letter is:
"...written approval from the manufacturer of a powered industrial truck
is required for modifications and/or additions if the modifications
and/or additions affect the capacity and safe operation of the truck.
However, please be aware that OSHA would consider the lack of
manufacturer's approval to be a de minimis violation if the employer has
obtained written approval from a qualified Registered Professional
Engineer after receiving no response or a negative response from the
powered industrial truck manufacturer. If the manufacturer's response
was negative, then the engineer, prior to granting approval for the
modification or addition, would need to perform a safety analysis and
address all safety and/or structural issues contained in the
