Short answer: Hanger capacity is determined by three data sets: the total load hung at once (part plus fixture), whether the part fits and rotates inside the basket without striking, and how many parts must be processed per shift. The right answer comes from evaluating all three together.
For anyone choosing a hanger shot blasting machine, this guide explains which data to collect, how the fixture affects capacity and the step-by-step process, with notes for buyers in Poland, Romania and Austria. For a model comparison, see our AK series guide.
Quick Summary: Which Data Determine Hanger Capacity?
- Load data: Heaviest part group plus fixture weight
- Geometry data: Largest diameter, height and rotation envelope
- Production data: Parts per shift and target cycle
- Surface target: Cleanliness grade required before coating
What Data Should Be Collected to Determine Hanger Capacity?
| Data | Why It Is Needed | Who Provides It |
|---|---|---|
| Part weight (kg) | To calculate total load | Production / quality |
| Part drawing | To check fit and rotation | Design |
| Material and surface condition | To estimate blasting time | Quality |
| Parts per day / shift | To set parts per hanger | Planning |
| Coating specification | To define the surface target | Customer / paint supplier |
How Does the Fixture Affect a Hanger Shot Blasting Machine’s Capacity?
The fixture is the hook, frame or basket that holds parts on the hanger. Its weight counts against hanger capacity, so a heavy fixture reduces the part load that can be carried.
Single Part or Multi-Part Hanger?
Large castings are usually hung one at a time. Mid-size parts can share a multi-arm fixture to raise parts per hanger, as long as they do not shadow each other from the blast stream.
What Does Unbalanced Loading Do?
If the centre of gravity shifts off the hanger axis, the load swings while rotating. This stresses the rotation motor and monorail and can leave uneven cleaning.
Does the Fixture Wear Too?
Yes. The fixture is blasted with the part every cycle and thins over time, so periodic inspection is essential for safe handling.
Is Hanger Capacity About Weight or Part Count?
| Approach | Weight-Based | Count-Based |
|---|---|---|
| Question | Can the hanger carry the heaviest load? | How many parts per shift? |
| Pros | Safe handling, long service life | Matches production targets |
| Cons | Throughput not visible alone | Limit may be exceeded on heavy parts |
| Right use | Sets the lower limit | Sets the model and hook count |
Example: Sizing Hanger Capacity
Assume 150 kg per part and a 100 kg fixture. Hanging 6 parts gives a 1,000 kg load, which stays below the 1.5-tonne AK-1 hanger capacity with margin. For 42 parts per shift, 7 hanger cycles are needed; once cycle time is confirmed by a sample blast, it becomes clear whether a single- or double-hook hanger shot blasting machine is required.
How Does Strong Makine Determine Capacity for a Hanger Shot Blasting Machine?
- Collect the part list, weights and drawings.
- Identify the heaviest and largest part group.
- Design the fixture and add its weight.
- Set parts per hanger from the shift volume.
- Propose a model from the AK series (0.5–7.5 t hanger capacity).
- Where possible, evaluate with a sample part, then commission.
What Should Buyers in Poland, Romania and Austria Prepare?
- Drawings and weights: Send 3D or 2D drawings and weights in kg for the heaviest parts.
- Coating specification: Share the surface cleanliness grade required by your paint system.
- Compliance: Machinery for the EU needs CE marking; Regulation (EU) 2023/1230 replaces Directive 2006/42/EC from 20 January 2027.
- Site data: Confirm power supply, floor space and dust collection rules.
Buyers in Poland, Romania and Austria who share this data at the start get a faster, more accurate hanger capacity proposal.
| Expert NoteChoosing hanger capacity from the catalogue value alone is a common mistake. When fixture weight and balanced loading are ignored, a hanger shot blasting machine that looks sufficient on paper ends up running at its limit on site. |
Who Is Strong Makine?

Frequently Asked Questions – FAQ
How is hanger capacity determined?
By evaluating total load, part dimensions and parts per shift together.
Does fixture weight count toward hanger capacity?
Yes. The hook, frame or basket weight is added to the total load.
Can several parts hang on one hanger?
Yes, with a suitable fixture, as long as the parts do not shadow each other.
Which documents are needed to size hanger capacity?
A part list, weights, technical drawings and the coating specification.
Why is a sample blast useful?
A trial with the real part shows cycle time and surface result more accurately than a paper calculation.
People Also Ask – PAA
Why are parts rotated in a hanger blasting machine?
Rotation lets the shot thrown by the turbines reach every face of the part.
What is the largest hanger capacity in the AK series?
The Strong Makine AK-5 has a 7.5-tonne hanger capacity.
How often should fixtures be inspected?
At regular intervals based on usage, checking for wear and cracks.
Which industries use hanger-type shot blasting?
Foundries, automotive, agricultural machinery, steel construction and defence.
