A pipeline construction company in a certain location in Russia was working on a remote gas pipeline project stretching across hundreds of kilometers of untouched terrain. The contractors needed to excavate trenches and then backfill them with sifted, rock‑free soil to protect the pipeline coating. However, the native soil contained abundant stones and frozen clumps. Manually removing debris was impossible at that scale. Mechanical screening with static equipment was too slow and lacked mobility.
The project manager needed a mobile, efficient solution. After researching online, he found YG’s mini excavator screening bucket. He wanted an excavator soil screener that could be mounted on his 12‑ton excavator and process frozen soil efficiently. YG recommended the YG012 model.
Technical Parameters Of The Mini Excavator Screening Bucket
YG offers six models of mini-excavator screening buckets. Based on the customer’s 12‑ton excavator and soil type, YG selected the YG012. Below are key specifications:
| Model Number | Applicable Tonnage of Excavator(T) | Operating Flow(L/min) | Working Pressure(Mpa) | Self Weight(Kg) | Number of Revolutions Per Minute(RPM) |
| YG01 | 1.5-3 | 20 | 10-12 | 158 | 35 |
| YG02 | 3.5-5.5 | 30 | 10-12 | 245 | 60 |
| YG08 | 6-10 | 45 | 12-15 | 530 | 65 |
| YG012 | 11-18 | 65 | 15-18 | 1020 | 65 |
| YG016 | 19-28 | 80 | 18-22 | 1920 | 65 |
| YG018 | 29-38 | 150 | 18-22 | 2430 | 65 |
The YG012 mini excavator screening bucket weighs 1020kg and operates at 65 RPM. This machine requires 65 L/min of oil flow and handles working pressures up to 18 MPa, making it robust enough for frozen soil conditions.
How This Excavator Soil Screener Performed On The Pipeline Route
The Russian contractor mounted the machine onto their 12‑ton excavator. The first test was on a section of frozen clay mixed with gravel and tree roots. Results were impressive:
- Screening speed: The mini excavator screening bucket processed 15‑18 tons of material per hour, separating stones larger than 50mm from fine soil. The screening drum’s 65 RPM rotation kept material flowing without clogging.
- Mobility advantage: The machine traveled with the excavator along the pipeline route. No separate screening plant or material transport was needed.
- All‑weather operation: The machine handled frozen clumps effectively. The steel drum and hardened teeth broke through icy material without damage.
The excavator soil screener also proved useful for backfilling. The operator screened soil directly into the trench, eliminating extra handling steps.
Customization For Russian Winter Conditions
YG engineers considered Russia’s harsh winters and the abrasive nature of frozen, rocky soil. Customizations included:
Low‑temperature hydraulic motor with specially formulated oil seals rated for ‑40°C.
Reinforced drum teeth made of wear‑resistant steel to withstand ice and rock impacts.
Heated hydraulic hoses to prevent oil thickening and maintain consistent flow in extreme cold.
Heavy‑duty bearings with cold‑weather grease to ensure smooth rotation at start‑up.
For the mini excavator screening bucket, YG also provided Russian‑language decals and a translated manual. The excavator soil screener was shipped with a spare set of drum teeth and bearing seals for field maintenance.
Tangible Results After Using The Mini Excavator Screening Bucket
After two months of continuous operation (10 hours/day, 6 days/week) through the Russian winter, the contractor recorded measurable gains:
Backfilling speed increased by 200% compared to manual debris removal.
Material transport cost was nearly eliminated, as the mini excavator screening bucket processed soil on‑site.
Pipeline coating protection improved significantly because screened soil contained no sharp stones.
Machine downtime remained minimal – only routine tooth replacements every 150 hours.
The machine paid for itself in just four months. The contractor has since ordered YG016 models for their larger 25‑ton excavators used on other sections of the pipeline.
Smooth Cooperation And Final Conversion
YG provided oil flow compatibility charts and operation videos. Sea freight was arranged from China to St. Petersburg port, then by rail to the project site. Remote video support via WhatsApp guided the first drum rotation test and hydraulic connection setup. The mini excavator screening bucket came with a one‑year warranty and a comprehensive spare parts kit.
