Made for the full range of pipeline & utility work
Wherever fine, clean padding protects the pipe and keeps the job moving.
Fine, clean padding to protect coating on large-diameter and mainline pipe.
Screening backfill for water, sewer, gas, and telecom trenching.

screening
Separating oversize rock and debris from native spoil so it can be reused.
tight ROW
The P3-120X keeps producing where access and swing room are limited.
mainline
P3-180X moves more material per pass to pad miles of pipe per day.
Wide screening area keeps saturated, sticky material from bridging in swampy ground.
Engineered for every American soil type
The United States features some of the most diverse and demanding geology in the world. Whether you are cutting trenches in the Northeast or the Southwest, Cobra padding buckets are constructed to conquer local soil challenges.
Dense Kern County clay-diatomite, seismic-grade cobble, and abrasive coastal sands, worked under strict dust and environmental limits. Precise screening keeps fine padding sand flowing while cleanly rejecting oversize cobble, and low-dust agitation helps operators stay inside California's tight air-quality and pipeline-bedding specs.
Ultra-dry, highly abrasive desert sands, gravels, and sandstone deposits that wear down metal fast. Built for superior longevity, the Cobra's wear-resistant materials hold up to the sandpaper-like abrasion of desert soils. You get fine, safe padding sand without constantly replacing bucket components.
The robust construction of the P3-180X handles the violent shaking needed to separate fine sands from the rigid caliche chunks. The Smart Valve prevents hydraulic blowouts when hitting sudden, dense rock pockets.
High-altitude freeze-thaw ground, hard Niobrara shale ledges, and rocky decomposed-granite soils across the DJ Basin. Heavy-duty framing and the Smart Valve handle cold-weather hydraulic stress and sudden rock ledges, separating shale and granite chunks from the fine bedding dirt that protects the line.
Hard caliche, dense rocky clay, and abrasive limestone that wreaks havoc on standard attachments. The robust construction of the P3-180X handles the violent shaking needed to separate fine sands from the rigid caliche chunks. The Smart Valve prevents hydraulic blowouts when hitting sudden, dense rock pockets.
Deep, rich agricultural topsoils mixed with heavy, dense glacial clay bases. The high 1.8-3.0 yrd³ capacities of the Cobra buckets allow operators to process massive volumes of this relatively cooperative soil extremely fast, ensuring miles of pipe are padded per day.
Saturated, sandy loam and sticky gumbo muds that cause bridging and clogging - the wide screening areas (up to 2.0 yrd²) keep material moving. The aggressive agitation prevents wet gumbo from bridging across the rotors, maintaining high-volume padding even in swampy ROWs.
Saturated sandy coastal-plain loam, sticky red clay, and limestone/karst rock over a high water table. Wide screening area and aggressive agitation keep wet sand and gummy clay from bridging, maintaining high-volume padding through swampy, water-logged ROWs.
Heavy, wet soils mixed with sharp Marcellus and Utica shale. High moisture content often clogs inferior screening buckets. The optimal 50-60 gpm hydraulic flow powers the aggressive screening shafts to chop through wet, clumping clay and cleanly reject sharp shale, protecting the pipeline coating flawlessly.
Boulder-strewn glacial till, hard bedrock outcrops, and rocky forest soils common to utility and water-infrastructure work. Robust construction absorbs the violent shaking needed to break out glacial boulders, while the Smart Valve prevents hydraulic blowouts when the bucket hits sudden buried bedrock.
