A hammer crusher from Changyu Machinery uses your excavator's hydraulic power to drive a heavy steel plate at high frequency. The plate presses into soil, gravel, or concrete and packs it tightly. The result is a firm, even base for pipes, slabs, and roads.
Compared with a walk-behind rammer, the attachment reaches deep trenches and steep slopes. The operator stays in the cab, away from the work face. The excavator supplies the power, so you do not need a separate engine on site.
Good compaction matters because loose fill settles over time. Settlement can crack slabs, damage buried pipes, and force costly repairs. A reliable excavator hammer crusher helps you build a dense, stable base before the next stage of work begins.
Drive oil pressure ranges from 100 to 200 kg/cm², and oil flow ranges from 45 to 170 L/min, depending on the model. Before you order, check that your excavator's auxiliary hydraulic circuit can deliver the flow and pressure your chosen model needs. If you are not sure, send us your excavator model and we will help you match it.
• Flat surfaces, such as yards and building pads
• Slopes and embankments
• Steps and stepped bases
• Trenches, including narrow and deep ones
• Complex foundation shapes
This range makes the excavator hammer crusher a practical choice for contractors who work on mixed sites.
Fixture requirements depend on pile type and size. Tell us what you plan to drive, and our team will advise on the setup. Before piling work, check ground conditions and pile positions with your site engineer, and follow local safety rules for machine operation.
Larger models have a heavier body and a bigger plate, so they deliver higher compaction tonnage. The ST-08 and ST-10 share the same plate size, but the ST-10 weighs slightly more.
Buyers should read the table in this order:
• Start with the excavator column to find the models that fit your machine.
• Compare oil flow and pressure with your excavator's auxiliary circuit.
• Check plate size against your typical trench width or work area.
• Review compaction tonnage to match your soil or fill type.
• ST-04: excavators of 4–9 tons
• ST-06: excavators of 11–16 tons
• ST-08: excavators of 17–23 tons
• ST-10: excavators of 23–30 tons
Excavators of about 9 to 11 tons fall between two models. Machines of about 23 tons can use the ST-08 or the ST-10. In both cases, send us your excavator brand, model, and hydraulic data, and we will confirm the best fit.
Changyu Machinery was founded in 2012 in Jiangyin, China. The company works in two areas: mining machinery and construction machinery. Its range includes crawler mobile impact crushers, jaw crushers, cone crushers, hydraulic breakers, and excavator attachments. Related tools in our range include grab buckets, digging buckets, hydraulic shears, and drum cutters, so you can source several attachments from one supplier.
You can learn more about Changyu Machinery on our company page. Buying from the manufacturer lets you ask technical questions directly and get clear answers before you order.
When you compare suppliers, ask for these items in writing:
• Model, plate size, plate thickness, and weight
• Required hydraulic flow and pressure
• Steel grade of the plate and body
• Mounting bracket or pin size for your excavator
• Packing method and delivery time
• Documents your market requires
Send us your list and we will confirm what we can provide. A clear written specification also protects both sides. It avoids confusion about fitment, hydraulic requirements, and delivery when the goods arrive at your port.
Ask us for the steel grade used on your chosen model. During use, check bolts, hoses, and fittings every day. A loose connection can cause oil leaks and power loss. Keep the plate clean of packed soil after each shift, and inspect it for cracks or heavy wear before each new project.
• Utility trenches: compact backfill around pipes and cables in narrow trenches
• Site preparation: prepare building pads and platforms before you pour slabs
Contractors who switch between buckets, breakers, and the compactor can add a Hydraulic Quick Hitch Coupler to speed up attachment changes. Ask us to include a coupler in your quotation.
• Power: the attachment uses excavator hydraulics, so you do not need to maintain a separate engine.
• Reach: the boom and arm place the plate in deep trenches and on slopes. Hand-guided machines need the operator to enter the area.
• Operator position: the operator works from the cab.
• Limits: for very small patches, a hand-guided rammer can be faster, because you do not need to bring in an excavator.
Your fleet may also include a hydraulic breaker. For that tool, read our guide on how to choose a hydraulic breaker bit.
• Excavator weight: match it to the model range.
• Hydraulic flow and pressure: confirm your auxiliary circuit meets the oil demand.
• Work area: check plate size against trench width and slope shape.
• Material: tell us your soil or fill type so we can advise on the size.
A model that is too small slows the job. A model that is too large can overload the excavator's hydraulic system.
For example, a contractor with a 15-ton excavator would start by looking at the ST-06. The contractor would then confirm that the machine's auxiliary circuit delivers 85–105 L/min at 100–130 kg/cm². If it does, the ST-06 is a suitable match.
We also welcome inquiries from importers, distributors, and contractors in Asia-Pacific, Europe, South America, and North America. If you are a distributor or OEM buyer, tell us your requirements and target market. We will review them and confirm what we can offer.
Site conditions differ by region, so include them in your inquiry. Useful details are the typical ambient temperature, the soil type, and the excavator brands in your fleet. This information helps our team check hydraulic fitment and mounting details before we quote.
If you want product details, a quotation, or technical support, contact our team. You can also message us on WhatsApp at +86 180 6828 1557 or email Annie@changyumech.com. Send your excavator model and application, and we will recommend the right excavator hammer crusher for your project.
Hammer Crusher Excavator Attachment | Changyu Machinery
Contractors and equipment buyers often search for a hammer crusher when they need faster, more even compaction on site. This guide explains the hammer crusher excavator attachment from Changyu Machinery: what it does, which models we offer, and what to check before you place an order.
This unit is a hydraulic compactor that mounts on an excavator. It compacts soil and concrete and can also drive piles. It is not a stationary hammer mill for crushing rock. If you need a rock-crushing plant, please see our crushing station range instead.
Jiangyin Changyu Machinery Co., Ltd. builds this excavator hammer crusher for importers, distributors, and project contractors. The sections below give you the technical data and buying tips you need to prepare a clear inquiry.
Hydraulic Hammer Crusher for Soil and Concrete Compaction
A hammer crusher from Changyu Machinery uses your excavator's hydraulic power to drive a heavy steel plate at high frequency. The plate presses into soil, gravel, or concrete and packs it tightly. The result is a firm, even base for pipes, slabs, and roads.
Compared with a walk-behind rammer, the attachment reaches deep trenches and steep slopes. The operator stays in the cab, away from the work face. The excavator supplies the power, so you do not need a separate engine on site.
Good compaction matters because loose fill settles over time. Settlement can crack slabs, damage buried pipes, and force costly repairs. A reliable excavator hammer crusher helps you build a dense, stable base before the next stage of work begins.
High-Frequency Compaction at 2000 cpm for 4–30T Excavators
All four models run at 2000 cpm (cycles per minute). This high frequency helps the plate transfer energy into the ground quickly.Drive oil pressure ranges from 100 to 200 kg/cm², and oil flow ranges from 45 to 170 L/min, depending on the model. Before you order, check that your excavator's auxiliary hydraulic circuit can deliver the flow and pressure your chosen model needs. If you are not sure, send us your excavator model and we will help you match it.
Compact Slopes, Trenches, Steps and Foundations with One Attachment
The excavator's boom and arm let you place the plate where hand tools cannot reach. One hammer crusher attachment can cover these jobs:• Flat surfaces, such as yards and building pads
• Slopes and embankments
• Steps and stepped bases
• Trenches, including narrow and deep ones
• Complex foundation shapes
This range makes the excavator hammer crusher a practical choice for contractors who work on mixed sites.
Hammer Crusher Attachment for Pile Driving and Extraction
Besides compaction, the unit can drive piles directly. With a suitable fixture, it can also drive and extract piles and handle crushing work. Contractors who need both compaction and piling can use one hammer crusher attachment for both tasks.Fixture requirements depend on pile type and size. Tell us what you plan to drive, and our team will advise on the setup. Before piling work, check ground conditions and pile positions with your site engineer, and follow local safety rules for machine operation.
Four Models: ST-04, ST-06, ST-08 and ST-10
Changyu Machinery offers four models. The table below lists the key technical data for each one.| Model | Compaction tonnage (t) | Frequency (cpm) | Oil pressure (kg/cm²) | Oil flow (L/min) | Plate size (mm) | Weight (kg) | Excavator (t) |
| ST-04 | 6–8 | 2000 | 100–130 | 45–75 | 900×550×25 | 300 | 4–9 |
| ST-06 | 10–16 | 2000 | 100–130 | 85–105 | 1160×700×28 | 500 | 11–16 |
| ST-08 | 18–22 | 2000 | 150–200 | 120–170 | 1350×900×30 | 900 | 17–23 |
| ST-10 | 24–30 | 2000 | 150–200 | 120–170 | 1350×900×30 | 950 | 23–30 |
Larger models have a heavier body and a bigger plate, so they deliver higher compaction tonnage. The ST-08 and ST-10 share the same plate size, but the ST-10 weighs slightly more.
Buyers should read the table in this order:
• Start with the excavator column to find the models that fit your machine.
• Compare oil flow and pressure with your excavator's auxiliary circuit.
• Check plate size against your typical trench width or work area.
• Review compaction tonnage to match your soil or fill type.
Fits Excavators from 4 to 30 Tons
Match the model to your excavator weight first:• ST-04: excavators of 4–9 tons
• ST-06: excavators of 11–16 tons
• ST-08: excavators of 17–23 tons
• ST-10: excavators of 23–30 tons
Excavators of about 9 to 11 tons fall between two models. Machines of about 23 tons can use the ST-08 or the ST-10. In both cases, send us your excavator brand, model, and hydraulic data, and we will confirm the best fit.
Built for Trench Backfilling and Foundation Compaction
Trench backfilling
Backfill in thin layers and compact each layer before you add the next. Choose a plate that fits the trench width so it can work close to the walls. Plate sizes range from 900 × 550 mm to 1350 × 900 mm.Foundation compaction
In foundation pits and stepped bases, the boom lets you reach corners and different levels without moving fill by hand. Proper compaction at this stage helps limit settlement later.Practical compaction tips
Keep fill moisture close to the level your project specification requires. Overlap each pass so no strip is missed. On open areas, work from the edges toward the center. Follow your site engineer's density requirements and test the result.Hammer Crusher Manufacturer in Jiangyin, China

Send us your list and we will confirm what we can provide. A clear written specification also protects both sides. It avoids confusion about fitment, hydraulic requirements, and delivery when the goods arrive at your port.
Hydraulic-Driven Hammer Crusher with Durable Steel Plates
The plate takes the impact and the wear, so its thickness matters. Plate thickness is 25 mm on the ST-04, 28 mm on the ST-06, and 30 mm on the ST-08 and ST-10. Body weight also affects compaction. The four models weigh 300 kg, 500 kg, 900 kg, and 950 kg.Ask us for the steel grade used on your chosen model. During use, check bolts, hoses, and fittings every day. A loose connection can cause oil leaks and power loss. Keep the plate clean of packed soil after each shift, and inspect it for cracks or heavy wear before each new project.
Ideal for Road Construction, Utility Trenches and Site Preparation
• Road construction: compact base layers and fill along road edges and slopes• Utility trenches: compact backfill around pipes and cables in narrow trenches
• Site preparation: prepare building pads and platforms before you pour slabs
Contractors who switch between buckets, breakers, and the compactor can add a Hydraulic Quick Hitch Coupler to speed up attachment changes. Ask us to include a coupler in your quotation.
Replace Plate Compactors and Rammers with an Excavator Attachment
If you already own an excavator, this hammer crusher turns it into a compaction machine. Here is how the two approaches compare:• Power: the attachment uses excavator hydraulics, so you do not need to maintain a separate engine.
• Reach: the boom and arm place the plate in deep trenches and on slopes. Hand-guided machines need the operator to enter the area.
• Operator position: the operator works from the cab.
• Limits: for very small patches, a hand-guided rammer can be faster, because you do not need to bring in an excavator.
Your fleet may also include a hydraulic breaker. For that tool, read our guide on how to choose a hydraulic breaker bit.
Compaction Force from 6 to 30 Tons, Chosen by Excavator Size
Compaction tonnage rises with each model: 6–8 t for the ST-04, 10–16 t for the ST-06, 18–22 t for the ST-08, and 24–30 t for the ST-10. Use these four checks to choose:• Excavator weight: match it to the model range.
• Hydraulic flow and pressure: confirm your auxiliary circuit meets the oil demand.
• Work area: check plate size against trench width and slope shape.
• Material: tell us your soil or fill type so we can advise on the size.
A model that is too small slows the job. A model that is too large can overload the excavator's hydraulic system.
For example, a contractor with a 15-ton excavator would start by looking at the ST-06. The contractor would then confirm that the machine's auxiliary circuit delivers 85–105 L/min at 100–130 kg/cm². If it does, the ST-06 is a suitable match.
