The RDBF is a flat-top skeleton bucket on rods for excavators from 10 to 50 t, built on the DBF bucket. Interlocking steel rods sift soil from rocks while you dig, so the material is sorted in the trench.
About this family
RDBF skeleton bucket: interlocking rods separate the material as you dig, for trenching, drainage and pipe bedding.
The RDBF skeleton bucket is for trenching with a large excavator. Interlocking steel rods sift soil and stones apart while you dig. It is used for utility trenches, drainage systems and pipe bedding.
Seven sizes, RDBF-120 to RDBF-500, come in widths from 1000 to 2000 mm with 5 or 6 teeth. Capacity runs from 536 to 2999 l (SAE) and weight from 271 to 1755 kg. Tip radius is 818 mm on the RDBF-120 and 1377 mm on the RDBF-500.
Rods are C45 steel as standard. Hardox® rods, special Hardox® rods and several rod spacings are options. Teeth are CAT J, BYG Futura or ESCO UltraLok, from J250 to J460. Brackets per size run from S45 to S90, MS10 to MS25, OQ45 to OQ90, M18 and M26, S1 to S3 and SW33 to SW66.

Which coupler is on your machine?
Pick the system on your machine and we put it in your enquiry. We check the bracket before we send the quote.
How to measure your coupler
Not sure which system it is? Three measurements tell us which bracket you need.
- Measure the diameter of both pins.
- Measure the distance between the pin centres.
- Measure the width between the inside faces of the ears.
If the coupler has a make or type printed on it, send that too.
