Product Description

Model RB-30 · 28–38 t carrier — finished 30-ton class shells, tagged and waiting for dispatch.

Model RB-20 · 18–26 t — 20-ton class units tagged for dispatch: chisel teeth and lip wear strips.	Model RB-30 · 28–38 t — full-width 30-ton class shell: bolt-on lip strips and reversible side cutters.
Models RB-20 / RB-30 — 20 and 30-ton class bodies built to different hitch drawings.	Models RB-30 / RB-45 — finished shells on final inspection, hitch bores machined.
Batch build · 20–30 t — after paint, before packing: teeth and adapters dressed, weld and dimension checked.	Model RB-20 · detail — lip, wing and hitch: wear strips, pinned adapters, machined pin boss with its grease point.
Export packing · RB-20–RB-45 — units wrapped, tagged and braced for container loading.	Export packing · RB-20–RB-45 — blocked against the container wall, teeth and pin bosses protected.

Application

• Quarry and shot-rock loading — load blasted limestone, granite and basalt from the muck pile into crusher feed. The deep bowl, wide opening and rock teeth keep the cycle short and the fines inside the bucket.
• Demolition and concrete removal — slabs, footings, columns and reinforced concrete. The teeth pry, the bolt-on edge takes the abrasion, and the bucket is not retired at the end of a single project.
• Rock trenching and hardpan — utility and drainage trenches through rock, caliche and compacted hardpan, including narrow widths built to the trench line rather than the catalogue.
• Road building and site preparation — cut and fill, rock clearance, verge work and the last pass before pavement. The same shell also dresses stockpiles and loads out spoil.
• Riprap and boulder handling — placing armour stone on embankments, river banks and coastal defences, where a controlled dump matters as much as breakout force.
• Slag, scrap and abrasive bulk — foundry slag, mill scale, scrap and other hot or abrasive material, handled with a wear package that can be renewed instead of replaced.
  

Features

• Wear package as a consumable — teeth, lip strips and side cutters are the parts that wear; all three are replaceable with hand tools, so the shell survives several wear cycles.
• Q345B shell, wear plate where it rubs — structural plate for the body, high-performance wear plate on the lip, the wings and the side cutters, because that is where the metal actually goes.
• Reinforced wings and corners — extra plate and gussets on the wall that scrapes the trench side, with a reversible side cutter at each corner.
• Deep, radiused bowl — a large open area and stowing surface with a smooth bowl, so wet clay and blasted rock release cleanly on the dump instead of packing.
• Machined pin joints — bores are machined after the shell is welded and every pin carries its own grease point, so the bucket stays tight rather than developing play.
• Bolt-on rock teeth — chisel or pick pattern on pinned adapters. A broken or dulled tooth is swapped on site; the adapter stays on the lip, with no cutting or re-welding.
• OEM hitch or quick coupler — pin-on to OEM pin diameter, arm width and centre-to-centre, or S-type, HS-type and grab-type quick coupler interfaces.
• Made to your capacity and width — 0.1–12 m³, shell widths and wing heights to drawing, matched to the machine you actually run.
• Paint and marking to your fleet — black, yellow, green, red or matched to your colour, with your branding and part-number marking.

FAQ

Q1: Which machines will this rock bucket fit, and how do I specify the hitch?
A: It is built for 3–125 t excavators and wheel loaders, pin-on to OEM dimensions or fitted with a quick coupler. Send us the machine brand and model, or the pin diameter, arm width and centre-to-centre distance, and we will confirm the hitch before quoting. If you already run a coupler, tell us the type (S-type, HS-type or grab-type) and we will match the interface.

Q2: What capacity and width can you build, and can it be customised?
A: Capacities from 0.1 to 12 m³ and shell widths to drawing, wider or narrower than standard. Custom work covers shell width, wing height, tooth pattern and adapters, wear plate layout, hitch dimensions and paint colour — production is against your sample, drawing or OEM part number.

Q3: What happens when the teeth or the edge wear out?
A: The teeth sit on pinned adapters and are replaced one at a time; the lip wear strips and side cutters are bolt-on and reversible, so they come off with hand tools rather than being cut and re-welded. The shell is not scrapped when the front wears. Teeth, adapters, wear strips and pins are kept in stock so a replacement set can ship with the next order.

Q4: Will the same bucket work on a wheel loader?
A: Yes. The same wear package is built for wheel loader linkage with a loader-style hitch and a wider, flatter shell for aggregate, riprap and rehandling work. Send the loader model and linkage dimensions and we adjust the geometry accordingly.

Q5: What is the lead time, packing, payment and warranty?
A: Standard lead time is 10–20 days after the sales contract, packed in fumigated seaworthy crates to export standard and braced in the container, with loading photos sent before the container is sealed. Payment by T/T, L/C, PayPal, Western Union or D/P. The quality guarantee is six months, and production is ISO9001 certified with TS and CE documentation available for the shipment.
