Attachment load chart compatibility requires the chart for the exact machine model, attachment type and support configuration at your placement height and forward reach. Request separate documentation for forks, buckets and other tools. Verify coupler system match and hydraulic specifications before work begins.
Shown as a configuration reference. Availability and the equipment offered for your project are confirmed separately.
Why each attachment needs its own load chart
A telescopic handler’s capacity changes with every attachment because geometry, weight distribution and boom loading differ between forks, buckets, jibs and platforms. Manufacturers publish distinct charts for each approved combination rather than one universal rating. Using a fork chart for a bucket placement can exceed safe limits even when load mass appears within the fork capacity range.
The JCB 540-140 HI-VIZ demonstrates configuration dependency with its low boom pivot point [S1]. That pivot arrangement affects stability and reach differently depending on the fitted attachment. Obtain the chart explicitly showing your attachment model on your machine model at the required height and outreach.
Required information for chart comparison
Build a compatibility assessment using the fields below. Each determines whether a proposed attachment can safely perform your placement task.
| Buyer input | Why it matters | Evidence to request |
|---|---|---|
| Load mass, dimensions and center of gravity | Chart capacity depends on weight distribution, not only total mass | Manufacturer load chart showing capacity at your load dimensions |
| Placement height and forward reach | Capacity reduces as boom extends and lifts | Chart covering your full working envelope with capacity at height and reach increments |
| Attachment type and model | Fork carriage, bucket, jib and platform configurations have different structural effects | Attachment identification plate, weight specification and approved chart reference |
| Coupler system | Quick-attach systems are often proprietary; physical fit does not prove chart validity | Written confirmation that attachment coupler matches machine system and that chart accounts for coupler weight |
| Hydraulic requirements | Powered attachments need flow, pressure and control compatibility beyond mechanical connection | Attachment hydraulic specification and machine capability statement with flow, pressure, valve type and any return or case-drain requirements |
| Support configuration | Stabilizer use, tire type, ground conditions and slope affect permissible loads | Chart section defining support conditions under which stated capacities apply |
Rejection conditions indicating incompatibility
Do not proceed if any of these conditions appear:
- Proposed attachment does not appear on machine manufacturer’s approved list or compatible chart index
- Supplier cannot provide a chart explicitly showing attachment model at your required height and reach
- Chart’s support assumptions do not match your site conditions
- Hydraulic requirements exceed machine’s published capability or require modifications not approved in writing by machine manufacturer
- Coupler system requires an adapter and no chart accounts for adapter’s added weight and geometry change
- Attachment manufacturer claims compatibility with a machine class but cannot provide specific machine maker’s approval documentation
How to compare charts for different attachment types
Obtain a separate chart for each attachment. Do not assume that a bucket rated for the same headline capacity as a fork carriage will perform identically at height and reach. Request these documents for every attachment:
- Load chart showing attachment model, machine model, and capacity at height and reach increments covering your placement envelope
- Attachment weight and center-of-gravity location
- Coupler compatibility statement confirming mechanical and load-chart approval
- Hydraulic connection diagram and specification if attachment is powered
- Operating restrictions such as prohibitions on load travel, speed limits or support requirements
Compare these documents against your placement task. If your required reach or height falls between chart increments, use the next most conservative value. Charts sometimes include footnotes restricting capacity under specific support or environmental conditions; read the complete document.
Coupler and hydraulic compatibility verification
A quick-attach coupler may allow an attachment to latch while remaining incompatible for load-chart purposes. Request written confirmation that:
- Attachment’s coupler matches machine’s system without modification or adapter
- Machine manufacturer’s chart accounts for coupler and attachment combination
- If an adapter is unavoidable, a revised chart or engineering approval covers adapted configuration
For hydraulically powered attachments, confirm flow rate, pressure, control signal type and any return-line or case-drain requirements. Machine’s hydraulic auxiliary output must meet these specifications under load. Do not assume that connecting hoses and achieving motion proves full compatibility.
Configuration-specific acceptance
Acceptance should verify that delivered machine, each attachment and all charts match approved specification. Qualified personnel must confirm:
- Machine and attachment serial numbers and model designations
- Presence and legibility of load-chart decals or plates on machine for each attachment
- Coupler engagement and release function
- Hydraulic connection security and absence of leaks if applicable
- Representative lift at required height and reach under site’s actual support conditions, observed by competent person familiar with approved operating plan
Keep all charts, attachment identification records and hydraulic specifications with the machine. When adding a new attachment later, repeat compatibility assessment.
Requesting comparable quotations for multi-attachment projects
If your project requires several attachments, list each in the request for quotation and ask for:
- Complete load-chart set covering every proposed attachment
- Confirmation that all attachments use common coupler system or that required adapters are included with revised charts
- Hydraulic auxiliary specifications if any attachment requires power
- Changeover procedure and any tools or training needed
- Storage or transport provisions if attachments will remain on site
Clarify whether quoted price includes all listed attachments or only base machine with fork carriage. State your placement geometry, support conditions and access constraints so suppliers can confirm that proposed configuration suits the site.

Frequently asked questions
Can I use a fork load chart for a bucket attachment?
No. Each attachment requires its own chart because geometry, weight distribution and structural loading differ. Obtain the chart explicitly showing the bucket model on your machine at required height and reach.
Does physical coupler fit prove load-chart compatibility?
No. Request written confirmation that the machine manufacturer's chart covers the attachment and coupler combination. An adapter or third-party coupler may void the original chart and require separate engineering approval.
What hydraulic information is needed for powered attachments?
Obtain the attachment's flow rate, pressure, control signal type and any return-line or case-drain requirements. Confirm that the machine's auxiliary hydraulic output meets these specifications under load.
How should I compare attachment charts from different suppliers?
Request a chart for each attachment showing your exact machine model, placement height, forward reach and support configuration. Compare capacity at the same chart points rather than headline ratings.
What documents should remain with the machine after attachment delivery?
Keep all load charts, attachment serial numbers, coupler compatibility statements, hydraulic specifications and operating restrictions with the machine. Repeat the compatibility assessment when adding a new attachment.
