A forklift compliance plate—also known as a data plate, nameplate, or capacity plate—is a permanent, durable label affixed to the forklift by the manufacturer. It is the authoritative source of truth for a forklift‘s technical specifications and operational limits, containing essential information such as weight, fuel type, and load capacity. This plate is not a guideline; it is a certified limit based on engineering design, stability testing, and regulatory requirements.
Regulatory Requirements – OSHA and ANSI Standards
OSHA mandates that all forklifts bear a durable, corrosion-resistant nameplate that is legibly inscribed with specific information. The core regulation is found in 29 CFR 1910.178, which requires that all nameplates and markings be maintained in a legible condition. OSHA has cited employers for operating forklifts without a present and legible nameplate.
Key regulatory points include:
Approved trucks must bear a label or marking indicating approval by a nationally recognized testing laboratory.
The user must ensure that all nameplates and markings are in place and legible.
Modifications and attachments that affect capacity require manufacturer approval and an updated data plate.
Operating a forklift with an illegible or missing nameplate is prohibited.
ANSI/ITSDF B56.1, the safety standard for low and high lift trucks, provides additional requirements for nameplates and markings.
Information Found on a Forklift Compliance Plate
While layouts vary by manufacturer, a standard forklift data plate includes the following core information:
Information Category Details
Identification Manufacturer name, model number, and serial number
Capacity Rated lifting capacity at defined load-center distances
Load Center Horizontal distance from the fork face to the load‘s center of gravity
Lift Height Maximum lift height (mast height)
Truck Weight Overall weight of the truck (without battery for electric models)
Fuel Type Electric (E), liquid propane (LP), diesel (DS), gasoline (G), or CNG
Voltage For electric forklifts, the battery voltage
Mast Type 2-stage, 3-stage, or 4-stage mast configuration
Tire Size and Type Solid, pneumatic, or cushion tires
Attachments Any attachments fitted (e.g., side-shifter) and their impact on capacity
Compliance Designation ASME B56.1 compliance and testing laboratory approval marks
Front Tread Overall width of the forklift‘s footprint
Capacity Chart: Many plates include a load capacity chart listing safe lifting capacities at specific load-center distances and mast heights.
Location of the Compliance Plate
The compliance plate is typically located in a visible and permanent location. Common placements include:
Inside the operator compartment – on the dashboard, near the steering column, or on the overhead guard leg
Near the operator‘s seat – on the instrument panel or cowl
On the mast or frame – near the mast base or engine hood
Reach trucks and pallet stackers – near the operator console
Electric forklifts – sometimes in the battery compartment
Behind the forklift – on the right side of the driver‘s view or in front of the steering column
If the data plate is missing, damaged, or unreadable, the forklift must not be operated until it is replaced.
Attachments, Modifications, and Plate Updates
Any modification or attachment that affects the forklift‘s capacity or safe operation requires manufacturer‘s written approval and an updated data plate.
Key requirements:
Attachments generally lower the forklift‘s capacity.
The updated data plate must reflect the new reduced capacity.
Operating with incorrect or outdated capacity documentation is a violation.
Front-end attachments not installed by the factory must be identified on the truck markings.
Why the Compliance Plate Matters
Safety: Exceeding the capacity or operating outside the plate‘s limits can cause tip-overs.
Legal Compliance: Operating without a readable data plate is a safety and compliance issue.
Operator Awareness: Operators must read and understand the plate to know the forklift‘s capabilities and limitations.
Maintenance and Parts: The model and serial numbers are essential for ordering correct parts.
Summary
The forklift compliance plate (data plate, nameplate, or capacity plate) is a permanent label affixed to every forklift by the manufacturer, containing critical information including rated capacity, load center, lift height, truck weight, fuel type, and attachment allowances. OSHA regulations under 29 CFR 1910.178 require that all nameplates be maintained in a legible condition, and operating a forklift with a missing or unreadable plate is prohibited. Any attachment or modification affecting capacity requires manufacturer approval and an updated plate. Operators must read and understand the data plate before each use to ensure safe operation within the forklift‘s certified limits.
