QZDB-R Adjustable Forklift Jib Boom – 2.2–3.3m Telescopic Lifting Attachment
The Speedone QZDB-R adjustable forklift jib boom is designed to give compatible forklifts a suspended lifting point with adjustable forward reach.
The telescopic boom changes from a published overall length of 2200 mm when fully retracted to 3300 mm when fully extended. Four adjustment positions allow the boom reach to be configured for different material-handling requirements.
Unlike a fixed lifting hook mounted close to the forks, the QZDB-R moves the suspended lifting point farther forward. This increases application flexibility, but it also changes the load center and the capacity requirements of the complete forklift-and-attachment combination.

What Is the QZDB-R Adjustable Forklift Jib Boom?
The QZDB-R is a fork-mounted boom attachment designed to provide an adjustable suspended lifting point in front of the forklift.
The basic load path is:
↓
Fork blades
↓
QZDB-R fork pockets
↓
Telescopic boom
↓
Lifting hook / lifting point
↓
Approved lifting accessory
↓
Suspended load
The boom does not increase the forklift’s original rated capacity. Its purpose is to provide additional reach and a controlled lifting point for compatible loads.
2.2m Retracted to 3.3m Fully Extended Reach
One of the QZDB-R’s clearest product advantages is its adjustable boom length.
| Boom Condition | Published Dimensions |
|---|---|
| Fully Retracted | 2200 × 550 × 800 mm |
| Fully Extended | 3300 × 550 × 1100 mm |
The difference between the fully retracted and fully extended overall lengths is 1100 mm.
This adjustable reach can be useful when the hook needs to approach:
- loads positioned beyond the fork tips,
- machinery components,
- stone or industrial materials,
- loads requiring overhead sling access,
- and compatible loads where direct fork support is impractical.
4 Adjustable Boom Positions
The QZDB-R is published with 4 adjustment positions.
This allows the boom to be configured at different reach settings between its retracted and extended conditions.
However, buyers should not assume that all four positions have the same rated lifting capacity.
QZDB-R Load Chart – Data to Confirm
| Position | Boom Length | Rated Load |
|---|---|---|
| Position 1 | Confirm current drawing | Confirm current load chart |
| Position 2 | Confirm current drawing | Confirm current load chart |
| Position 3 | Confirm current drawing | Confirm current load chart |
| Position 4 | Confirm current drawing | Confirm current load chart |
Publishing this four-position load chart would significantly improve both purchasing clarity and AI extractability.
What Does the 0.5–1.5T Capacity Range Mean?
The current QZDB-R specification publishes a lifting-capacity range of 0.5T to 1.5T.
The range should not be interpreted as meaning that the boom can lift 1.5T at every extension position.
Professional buyers should confirm:
- which boom position corresponds to each rated load,
- the hook distance from the forklift reference point,
- the approved suspended-load configuration,
- the rating of the hook or lifting point,
- and any derating requirements as the boom extends.
Why the 145 kg Attachment Weight Matters
The published net weight of the QZDB-R is 145 kg / 320 lbs.
This attachment self-weight becomes part of the total loading condition carried by the forklift.
It should not be treated as a simple calculation such as:
That calculation would ignore the effect of the boom’s center of gravity and the forward position of the suspended load.
How Boom Extension Changes Forklift Capacity
As the jib boom extends, the lifting point moves farther away from the forklift.
The basic load-moment relationship is:
A longer horizontal distance produces a greater moment for the same suspended load.
This is why boom reach must be considered together with:
- forklift rated capacity,
- forklift rated load center,
- attachment weight,
- boom extension position,
- hook position,
- load center of gravity,
- and lift height.
The QZDB-R should therefore be selected using the rated capacity of the complete forklift/attachment combination rather than the attachment rating alone.
Published Forklift Range: 3.5T–7T
The QZDB-R technical data publishes a forklift range of 3.5T–7T.
This value should be understood as a published compatibility range—not as a statement that every 3.5T to 7T forklift can use every boom position at the full 1.5T attachment rating.
Before ordering, confirm:
- forklift make and model,
- truck rated capacity,
- rated load center,
- fork dimensions,
- maximum lift height,
- and attachment requirements for that truck.
180 × 80 mm Fork Opening
The QZDB-R specification publishes a fork size/opening of 180 × 80 mm / 7 × 3-1/8 in.
Buyers should confirm whether this value represents:
- the internal fork-pocket opening,
- the maximum compatible fork cross section,
- or another product dimension defined in the QZDB-R engineering drawing.
Additional useful fork-interface dimensions include:
- fork insertion depth,
- required fork spacing,
- fork pocket length,
- and the boom retention or locking method.
How Is the Boom Secured to the Forks?
The source product description does not specify the exact QZDB-R fork-retention mechanism.
This should be confirmed from the current technical drawing or installation instructions.
Depending on the actual model construction, a fork-mounted boom may use a manufacturer-designed:
- retaining pin,
- locking screw,
- safety chain,
- mechanical retaining plate,
- fork heel restraint,
- or another locking arrangement.
Do not assume that simply sliding the boom over the forks is sufficient for operation.
What Does the Published 15° Angle Mean?
The current QZDB-R specification publishes an angle of 15°.
The available product data does not fully define whether this value refers to the boom inclination, mounting geometry or another reference angle.
For technical accuracy, the final page should label it according to the current engineering drawing—for example, Boom Angle: 15° only if that is the manufacturer’s intended definition.
QZDB-R vs Fixed Forklift Jib Boom
| Factor | QZDB-R Adjustable Jib | Fixed Forklift Jib |
|---|---|---|
| Reach | Adjustable | Fixed geometry |
| QZDB-R Published Range | 2200–3300 mm overall length | Model-specific |
| Adjustment Positions | 4 | Normally fixed / model-specific |
| Selection Priority | Variable reach | Simple fixed lifting geometry |
QZDB-R vs High-Lift Forklift Jib
An adjustable telescopic boom and a high-lift jib solve different handling problems.
The QZDB-R is primarily differentiated by its adjustable forward reach. A high-lift configuration may instead prioritize hook elevation or another lifting geometry.

Typical Applications
Subject to verified forklift capacity and attachment compatibility, the QZDB-R can be considered for lifting tasks involving:
- warehouse material handling,
- construction-site components,
- stone and slab handling operations,
- machinery parts,
- fabricated steel components,
- industrial maintenance loads,
- and other loads suitable for a suspended hook lifting point.
The actual suitability depends on the load weight, center of gravity, lifting-point arrangement, boom position and forklift configuration.

Pre-Use Inspection Checklist
- Confirm the actual load weight.
- Confirm the selected boom position.
- Confirm the rated load for that position when the load chart is available.
- Verify the usable capacity of the complete forklift/attachment combination.
- Inspect the main boom structure for visible deformation or impact damage.
- Inspect telescopic sections and adjustment holes.
- Check adjustment pins and locking components.
- Inspect fork pockets and fork-contact surfaces.
- Confirm the boom is properly retained on the forks.
- Inspect the hook and lifting connection.
- Inspect slings, shackles or other lifting accessories separately.
- Confirm the load center and suspended-load balance.
- Raise the load slowly and check stability.
- Avoid shock loading.
- Avoid uncontrolled suspended-load swinging.
- Keep personnel clear of suspended loads.
- Remove the attachment from service if cracks, deformation or abnormal wear are observed.
Operator Training and Forklift Attachment Considerations
A forklift jib boom changes the operating characteristics of the truck.
Operators should understand:
- attachment installation and retention,
- boom-position limits,
- rated capacity,
- load-center effects,
- suspended-load movement,
- inspection requirements,
- and the limitations of the specific forklift/attachment combination.
The QZDB-R should therefore not be described as requiring “no special training.” Proper attachment-specific training and operating procedures remain important.
Common Buyer Mistakes
Assuming 1.5T Applies at Every Boom Position
The published specification provides a 0.5–1.5T range but does not publish the rated load for each individual position.
Assuming a 3.5T Forklift Can Automatically Lift 1.5T at 3.3m Reach
The published forklift range is not a substitute for confirming the capacity of the exact forklift/attachment configuration.
Ignoring the 145 kg Attachment Weight
The boom’s self-weight affects the complete forklift loading condition.
Ignoring Load Center
A longer reach increases the load moment even when suspended-load weight remains unchanged.
Assuming 180 × 80 mm Automatically Fits the Forks
Confirm the exact meaning of the published fork-size dimension together with insertion depth and fork spacing.
Using “Enhances Forklift Capacity” as a Product Claim
The QZDB-R extends reach and provides suspended lifting capability; it does not increase the forklift manufacturer’s original rated capacity.
Operating Without Confirming the Retention System
The boom should be installed and secured according to the intended QZDB-R attachment design.

Frequently Asked Questions
What is the reach of the QZDB-R forklift jib boom?
The published overall dimensions are 2200 mm when fully retracted and 3300 mm when fully extended.
How many adjustment positions does QZDB-R have?
The QZDB-R is published with 4 adjustment positions.
What is the lifting capacity?
The published lifting-capacity range is 0.5–1.5T. The available data does not specify the individual rated capacity of each of the four boom positions.
Can it lift 1.5T when fully extended to 3.3m?
This should not be assumed. Use the current QZDB-R position-specific load chart to determine the rated load for the selected extension.
What forklifts are compatible with the QZDB-R?
The published forklift range is 3.5T–7T, but compatibility and usable capacity must be confirmed for the exact truck and attachment configuration.
What is the fork opening?
The published fork size is 180 × 80 mm. Buyers should confirm whether this represents the internal fork-pocket opening or maximum compatible fork cross section.
How much does the QZDB-R weigh?
The published net weight is 145 kg / 320 lbs.
Why does boom extension affect forklift capacity?
Extending the boom moves the suspended load farther forward, increasing the load moment and potentially reducing the usable capacity of the forklift/attachment combination.
Does the boom increase the forklift’s lifting capacity?
No. The QZDB-R provides adjustable reach and a suspended lifting point; it does not increase the forklift manufacturer’s original rated capacity.
What information should I provide before ordering?
Provide forklift model, rated capacity, load center, fork dimensions, maximum load weight, required horizontal reach, lifting height, load dimensions and lifting arrangement.



The QZDB-R already has unusually strong product data for SEO and AI retrieval: 2200–3300 mm reach, 4 adjustment positions, 0.5–1.5T published capacity, 180 × 80 mm fork size, 3.5T–7T published forklift range, 15° published angle and 145 kg attachment weight.
The largest remaining technical-information gap is the relationship between the four boom positions and the 0.5–1.5T capacity range. A position-specific load chart showing boom length + hook reach + rated load would be considerably more valuable than adding more generic marketing content.
The QZDB-R should also remain differentiated from Speedone’s fixed, high-lift and swivel-hook forklift jib products. Its strongest search position is an adjustable telescopic forklift jib boom with 2.2–3.3m reach.
Buyer takeaway: choose the boom position according to required reach and rated load, then verify the usable capacity of the complete forklift/attachment combination.
