"TRS" Skeleton (Sorting) Buckets are designed especially for handling stone, debris, and coarse aggregate. In GRAXX portfolio their designation is "TRS". The Skeleton (Sorting) Buckets can have a blade with an angle blade or teeth at their end.

There are two types of boom fixtures for skeleton (sorting) buckets:

The main assemblies of skeleton (sorting) buckets are:

  • coupling assembly
  • steel scoop
  • blade
  • additional replaceable blade, a so-called angle blade
  • tooth - alternatively with an angle blade

The whole skeleton (sorting) bucket structure is made using welding technology with mounted coupling components (the brackets). The jacket (ribs) of the scoop is made of HARDOX 450HB steel and reinforced with an additional flat bar. Steel sides of the scoop are reinforced at the front with HARDOX 450HB components. The blade is made of steel with a hardness of about 500 HB (standard 470 540 HB).

Depending on the type and size of the skeleton (sorting) bucket, the manufacturer equips it with Combiparts or CAT-type teeth.
