Shell style, capacity, permitted load, opening and grab mass should be reviewed together rather than choosing from volume alone.

Maximum load is a catalogue grab value, not a statement that a particular crane or carrier can safely handle that load.

Selection guidance

Closed or open sides? Start with the material

Closed-side variants retain finer bulk material, while open-side variants can suit duties where material needs to pass through the shell structure. The exact selection still depends on the material and operating geometry.

  • Material type, density and particle size
  • Required volume and permitted load
  • Closed- or open-side shell requirement
  • Opening and working geometry
  • Carrier or crane, hydraulics and rotator

Rotator and system

Specify the attachment and rotator together

The catalogue recommendation is a starting point. Rotator load ratings, flow, connections and the complete suspension arrangement must be checked against the selected grab and duty.

Send us the material, machine and duty

We can narrow the range and recommend the configuration around what you need to handle and what the grab is going onto.
