A NEW

MULTI-FUNCTION TOOL:

THE CUTTER-BUCKET-COMBINATION

MAIN AREAS OF APPLICATION

One Tool - Four Functions

Excavating, cutting, crushing and mixing in one

operation - all this is possible with the Cutter-Bucket

Combination. The Cutter-Bucket was developed by

TEREX | Schaeff in cooperation with U.T.S. Umwelt-

und Technologie-Service GmbH, Stuttgart.

Typical areas of application

• In the trench as cutter, bucket and ground

stabilizer

• On fl at terrain as cutter and ground stabilizer

• On the heap as recycling unit

Cutter-Bucket - proven in road work and trenching

Combining the proven and tested with the innova-

tive - the Cutter-Bucket is a further development of

the Hydraulic Cutting Unit by TEREX | Schaeff. The

Cutting Unit has been equipped with an additional

U.T.S. Bucket System. The special strength of the

Cutter-Bucket Combination has been demonstrated

so far especially in road and pipeline construction.

The combination allows excavating the softer mate-

rial with the Cutter-Bucket; more solid rocks can be

cut the same time with the integrated cutter. Another

advantage: The grinding action of the cutter prevents the bucket

from becoming jammed - even in deep trenches. In a third step,

the material picked up with the bucket can be crushed directly in

the trench. The bucket thereby acts as a chute for the excavated

material. The cutter serves as a breaker or coarse grinding tool. Af-

ter crushing, the prepared material is ready for immediate reuse on

site. Excess material requiring removal can easily be loaded with the

Cutter-Bucket.

Many variations - Including level terrain applications

Cutting on level terrain is also possible with the Cutter-Bucket. The

bucket assumes the guide function and sets the depth for the cut-

ting operation. Cutting vibration is thereby largely reduced and the

carrier device is exposed to less strain.The cut, fi ne-grain material

can be picked up with the bucket and reused on site or loaded

for transport. With the help of the integrated grinding unit, the cut

material can also be mixed with additional excavated material and

reused as needed.

Cutter-Bucket - There is not better way to handling mounds

The Cutter-Bucket-Combination can also be used at recycling lo-

cations to prepare and crush concrete, asphalt and stony ground

material. The Mixing-Cutter-Bucket was also developed as a de-

vice especially for ground preparation and ground conditioning. The

Mixing-Cutter-Bucket WS60-MFL1000 is equipped with a feeding

MAIN ADVANTAGES OF THE

CUTTER-BUCKET

• No tool change necessary

• Smooth and gentle machine operation

• Accurate guidance of the cutter through

the bucket, thereby reducing vibration

• Direct crushing of the excavated material

on site for further use at the construction

site (e.g. backfi lling)

• Mixing of cut material with absorbent

ground material

• Cost reduction for tools, material hauling

and landfi ll site costs

• Cutter can also be used conventionally

without bucket attachment

• Cutter-Bucket system can be retrofi tted

on all TEREX | Schaeff Cutters

PATENTED SOLUTIONS

The Cutter-Bucket-Combination is an innovative solution, developed

from practical experience and patent-protected in many countries

worldwide, for example:

• European Patent No. EP1 147 265

• U.S. Patent No. US6 626 499.

The sophisticated modular system makes our patented system also

available as retrofi t-kit for the already existing rock cutter.Material size limiter bar

Breaking-Mixing Chamber

Breaker bar

Cutting drum

• Mixing of the layered

or excavated material

• Mixing in trenches

and level ground

• Mixing in the bucket

system on the Cutter-Bucket allowing absorbent materials such as

lime or additives to be measured into the mixing chamber. The mate-

rial picked up by the bucket is crushed by the grinding unit. The addi-

tives are mixed in at the same time and processed into a homogenous

ground material. A switchable hydraulic motor with two cutting speeds

ensures optimal operation of the Mixing-Cutter-Bucket. Especially ef-

fective: Powerful cutting and crushing at a low speed and high torque.

Mixing, by comparison, is performed at a high speed of the cutting

drum and reduced torque.

It pays off - Saving time and money

Not only the performance but also the economic advantages of the

Cutter-Bucket are convincing: There is no need to change devices

or tools; intermediate storage is not necessary, material supply and

dumping are reduced, transport distances are avoided.

SAMPLE COST CALCULATION

Increasing the productivity and capital ROI of its customers has always highest priority at TEREX.

The economic benefi ts of the Cutter-Bucket are especially convincing. There is no need to change devices or tools; intermedi-

ate storage is not necessary, material supply and dumping are reduced, transport distances are avoided.

Sample calculation with WS60-FL800:

Cutter-Bucket-Combination in use without required change of tool or carrier device

3. Cost savings compared to conventional modes of operation per ton when using the Cutter-Bucket-Combination:

Customary costs:

a) Landfi ll site fees: approx. 4.00 €/to

b) Hauling and transport costs: approx. 3.00 €/to

c) Supply and fi lling material: approx. 3.00 €/to

1. Cutter-Bucket operation (60 kW):

Cutting power x yield per running meter = Added value (Turnover per hour)

approx. 60 m/h x 5.00 €/running meter = 300.00 €/h

2. Crushing/Recycling operation (breaker) (60 kW):

Breaking power x yield per ton = Added value (Turnover per hour)

approx. 80 t/h x 3.00 €/t = 240.00 €/h

Savings approx. 10.00 €/t or 20.00 €/cbm
