Excavator Sieve Bucket Application and Operating Guide

An excavator sieve bucket, also known as a skeleton bucket, riddle bucket or screening bucket, is a versatile attachment used for excavation and demolition work. It gets its name from its open framework design which looks like a skeleton.

Sieve Bucket Application:

Topsoil screening - Great for removing rocks, roots and debris from excavated topsoil for landscaping uses.

Pipe bedding preparation - Sifts boulders and stones from sand/gravel to create properly sized pipe bedding.

Garden soil blending - Mixes and blends soil, compost and amendments into a loose friable blend by sifting.

Land clearing - Removes stumps, roots and embedded debris when clearing land for construction or farming.

Gravel washing - Sifts and washes gravel and crushed stone to remove fines and dust.


Sieve Bucket Sifting Performance Factors:

Bucket fill level - Overfilling reduces sifting efficiency as materials do not have enough agitation and retention time. Operators should not exceed 2/3 capacity.

Digging angle - A flatter digging angle increases agitation for better sifting. Steeper angles result in materials discharging too quickly.

Swing speed - Faster swing motion while sifting creates more agitation and material turnover for improved screening.

Grid condition - Worn or clogged grids reduce sifting performance. Regular inspection and maintenance is key. 

Sieve Bucket Operating Tips:

● Take small bites when excavating packed, hard or frozen ground. Don't overload the bucket.

● Curl in towards the excavator when penetrating tough material to avoid excessive side loads.

● Use the bucket's curved edge to peel back layers when grading or digging trenches.

● Carry the load low for better stability. Avoid lifting the boom too high.

● Adjust the bucket curl and tilt angle to retain material when traveling.

● Use the bucket's teeth to rake and sift through debris piles.

● Shake the bucket with quick curl motions to dislodge sticky material. Always check behind and around the excavator when swinging the bucket. 

Following safe operating practices will lead to efficient, productive use of the excavator sieve bucket. Pay close attention to your surroundings and watch for potential hazards when digging. Stop work immediately if any safety issues arise. With experience, you'll find the sieve bucket capable of tackling a wide variety of excavation and demolition challenges.
