Calculate Lost Load of Fork Truck
with Morse Drum Handling Attachment
Information is provided in the Operator's Manual of each Morse forklift drum handler to enable
the fork truck manufacturer, or representative to modify the fork truck nameplate information
to reflect the capacity of the fork truck with the Morse attachment.
Morse does NOT calculate the capacity of the fork truck.
Avoid exposing forklift operators to potential danger Limit company liability
Calculate the effect of each Morse drum handling attachment on your fork truck capacityThe 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 capacity.
- Refer to Operator's Manual for dimensions of each 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 handling attachment.
- 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.
IMPORTANT: See Operator's Manual for each Morse forklift drum handler for Center of Gravity Dimensions to Calculate Lost Load on Your Fork Truck
Applicable OSHA Regulations1910.178(a)(4)
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 centered.
The user shall see that all nameplates and markings are in place and are maintained in a legible condition.

An 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 their files.
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 manufacturer's disapproval...."
