GeoDrop

Bucket soil adhesion prevention material

GeoDrop is registered as an official new technology by the Japanese government.

Presented at the 79th Annual Academic Lecture Meeting of the Japan Society of Civil Engineers (JSCE) National Convention in FY2024

Development of environmentally friendly materials to prevent soil adhesion to hydraulic excavator buckets

The effectiveness of Geodrop was presented at the 79th Annual Academic Conference of the Japan Society of Civil Engineers in 2024 under the title, “The effectiveness of Geodrop.”

Work time and CO2 emissions reduced by approximately 10%

By reducing bucket swinging and impact work by approximately 90%,

It is estimated that the operating hours of heavy machinery can be reduced by approximately 10%.

The clay will not adhere easily.

At an earthwork site, a hydraulic excavator with GeoDrop attached and one without the treatment were operated for the same period of time (digging approximately 100 m3), and it was confirmed that the weight of residual soil was reduced by approximately 70%.

Noise suppression and reduced impact on the surrounding environment

It has been confirmed that the reduction in vibration and impact work reduces noise by approximately 12 dB, and is also effective as a vibration countermeasure. Since clayey soil is less likely to adhere, bucket vibration and impact work is almost unnecessary.

The effect remains even after wear

Direct shear test results for abraded fluororesin

It has been confirmed that the coefficient of friction is reduced even when the fluororesin is worn down in a wheel tracking test.

We have also confirmed that the effect lasts not only on organic soil (kuroboku) and Osaka Kaisei clay, but also on Kasama clay and bentonite mixed soil.

Specification

Example of bucket size

We can also accommodate sizes other than those listed above. Please contact us.

In addition, since it is more effective to attach them as far back as possible in the bucket, we recommend eliminating the installation of one panel in the front row of the bucket and shifting the entire panel back.

Use of GeoDrop in embankment construction

The soil adhesion prevention effect will last if you wash the bucket.

Applicable soil type

clay soil
Silt
sandy soil

Development Background

When using a hydraulic excavator to excavate clayey soil or load it onto a dump truck in earthworks, ground improvement work, piling work, etc., the following issues were encountered:

Clay soil is particularly prone to sticking to the bucket, reducing work efficiency. In the case of automatic and autonomous hydraulic excavators, which have been increasingly put to practical use in recent years, work efficiency decreases even further when clay soil adheres to the bucket.
When a large amount of clayey soil adheres to the bucket, it is shaken off by shaking it or slamming it down, but this generates noise and vibration and makes the bucket more susceptible to fatigue and damage.
In cases where bucket swinging is not possible due to the presence of residential houses nearby, workers must remove the soil by hand or by washing it with water, which is time-consuming and hard work.

Geodrop is expected to solve these issues and also reduce work time and reduce CO2 emissions.

Notes and Disclaimers

Regarding the installation, Obayashi Corporation, Obayashi Road, Hirotec, or the distributor shall not be liable under any circumstances, except in the case of willful intent or gross negligence.

We are not responsible for any peeling or curling.

Do not install the product in any manner other than as described in this product catalogue.
Do not resell purchased products.
Do not engage in any acts that infringe on the intellectual property rights (patent rights, etc.) related to this product, such as manufacturing or selling counterfeit products.
Do not apply force to the product before it is installed in the bucket.
When using a bucket to work with concrete blocks, metal pieces, asphalt rubble, rock chunks, etc., keep in mind that the product may be scratched or peeled off.
After installing the product, visually inspect it for peeling or curling depending on the frequency of use.
After the product is installed, if it appears as if it is about to come off, take measures such as servicing the bucket and spot welding it again.
Spot welding should be performed so as to avoid the weld defects described in JIS Z3001-4 "Welding terminology - Part 4: Weld imperfections" (We are not responsible for peeling or curling caused by welding defects, regardless of the procedures given in the manual).
We are not responsible for any peeling or curling that occurs at the points where purchased products are cut, processed, and spot welded, regardless of the procedures specified in the manual.
