Executive summary A box dumper tips a full bin so its load pours out without anyone lifting or shovelling it. Our fixed hydraulic dumper in this test tips an orange chip bin on a blue A-frame and brings it back, driven by two yellow cylinders. The load it must lift follows from the bin volume and the bulk density of the chips. Both are set per project.

What the video shows
Our dumper stands in the workshop for its run test. The orange bin sits on a blue A-frame, with two yellow hydraulic cylinders between frame and bin. A blue hydraulic power unit and a white control box stand at the side. The on-screen caption calls it a fixed tipping and discharge unit for metal chip carts.
The bin starts tilted at its low point. The cylinders extend and the bin rotates up and over to its tipping position, then it rotates back down to rest. The test is run empty.
How the box dumper works
| Step | What happens |
|---|---|
| Load | The bin rests at its low point, ready to be filled or set in place |
| Tip | The cylinders extend and the bin rotates over the pivot |
| Discharge | The load pours out over the bin lip |
| Return | The cylinders retract and the bin comes back down |
Two cylinders lift the bin evenly, so it does not twist on the pivot. The power unit beside the frame supplies the oil, and the control box starts and stops each move.
Sizing the bin load
Illustrative example for a bin 1.0 m long, 0.8 m wide and 0.6 m deep:
| Item | Value |
|---|---|
| Bin volume, 1.0 × 0.8 × 0.6 | 0.48 m³ |
| Bulk density of chips (illustrative) | 1,000 kg/m³ |
| Chip load, 0.48 × 1,000 | about 480 kg |
Chip bulk density changes a lot with the chip shape and the oil on it, so weigh a full bin of your own chips. Add the bin’s own weight to get the load the dumper must tip.
What the run test checks
| Check | What we look for |
|---|---|
| Full stroke | The bin reaches its tipping position and returns |
| Smooth motion | No jerks or stalls through the cycle |
| Even lift | Both cylinders move together |
| Controls | Start and stop respond at once |
| Leaks | No oil at the cylinders, hoses or power unit |
The test is run before shipping, first empty and then with a load where the project calls for it.
Controls and safety
The control box carries a power switch, a green start button and a red stop button. Keep people clear of the bin and the area it tips into while it moves.
The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets general requirements for packaging machines.
Selection checklist for a box dumper
- Bin size and its empty weight.
- Material and its bulk density.
- Height the load must pour into.
- Bins per hour.
- Fixed or mobile unit.
- Power supply on site.
Engineering FAQ
Q: What does this dumper tip? A: Bins of metal chips from machining, as in our test. Other bulk solids in bins can be tipped the same way.
Q: How does it lift the bin? A: Two hydraulic cylinders rotate the bin over its pivot, fed from the power unit beside the frame.
Q: How heavy is a full bin? A: Bin volume times bulk density, plus the bin. Our 0.48 m³ example holds about 480 kg of chips.
Q: Is it fixed in place? A: Yes. This unit stands fixed, and the chip cart is brought to it.
Q: How is it stopped? A: The red stop button on the control box stops it.
Next step
We plan your box dumper in three steps:
- Submit your layout drawing with bin size and material to info@fhopepack.com.
- Receive a proposal within 48 hours, with the tipping height and load.
- Book a site survey to check the site layout and power.
