Application

Emptying a mesh pallet holding 300 kilograms of bulk material into the hopper – controlled, not all at once

A mesh pallet filled with bulk material weighs up to 800 kilograms. Lifting it is a question of payload – emptying it is not. Tip it too fast and the hopper overflows, dust fills the hall and half the load lands beside it. Tip it too slowly and you stand there twice as long.

Component
Mesh pallet, small load carrier, drum, special container
Weight
50 to 800 kg
Tipping angle
up to 135 degrees
Movement
lift, guide, tip under damping
Frequency
20 to 200 emptyings a shift
Environment
hopper, machine feed, decanting station
01 — The task

The container is not hard to lift. It is hard to meter.

Pick the container up, guide it over the hopper, machine or target container, tip it under control, empty it, swing it back and set it down. Tipping is the actual process: it has to start slowly until the material flows, and must not snap through at the end when the container becomes light and the centre of gravity shifts. With small load carriers the parts must not drop – visible parts take any fall badly. And in food processing, complete emptying is not a convenience but a hygiene requirement.

02 — The solution

How we solve it

The tipping movement is the process, not a side effect

A tipping unit that knows only two end positions does not solve this task. We design the tipping drive damped and infinitely variable, holding in any intermediate position. That lets the operator meter the flow: tilt slowly at first until the material breaks, then tip on evenly. At the end, defined end-position damping holds the light container – exactly where an undamped unit snaps through and throws the remainder out.

Positive location instead of friction

While tipping, the centre of gravity travels far beyond the mount. A mount relying on clamping force alone is the wrong choice here. We work with positively locating mounts that take the container at its design points – a mesh pallet at the feet or the frame, a small load carrier at the rim, a drum at the bead or clamping ring. Locking is mechanical, not pneumatic: what holds must hold without compressed air too.

Drop height determines overall height

How tall the unit has to be follows from the hopper rim – but also from what the material tolerates. Bulk material falling one and a half metres raises dust and breaks. We therefore plan the emptying position as low as possible and let the container travel with the tipping motion rather than raising it above. For sensitive material a chute or a swivelling bottom is added; that is not an accessory but part of the task.

03 — What changes

At the workstation afterwards

  • Emptying becomes metered instead of sudden – no overflow, nothing beside the target.
  • The container is positively located; slipping out while tipping is ruled out.
  • Dust and breakage decrease because drop height is planned rather than accepted.
  • One person operates the station without lifting, tipping or supporting.
  • Complete emptying and cleaning are designed in, not improvised.
Frequently asked questions

Frequently asked questions

Up to what weight does hand-guided operation make sense?

For tipping itself weight hardly matters, because the drive takes it – 800 kilograms and more are common. Guiding sets the limit: if the container also has to be moved freely across an area, around 500 kilograms is the threshold above which a guided rail system beats a free-standing unit.

How do you prevent dust while emptying?

Through three things: low drop height, damped tipping speed and an emptying position close to the hopper rim. Only when those are exhausted does extraction help. Reverse the order and you pay to extract what need never have been raised.

Does this work in food processing too?

Yes, with the appropriate design: stainless steel in the product area, smooth surfaces, no open sections where residues collect, and a mount that can be removed and cleaned without tools. The tipping kinematics stay the same – the difference is in material and finish.
