HT260 Crawler Excavator — Kawasaki Hydraulics, Built for Attachment Work
The HT260 is a 25.4-ton crawler excavator powered by a Cummins 6BTA5.9 engine with a full Kawasaki hydraulic system. Its 240 L/min × 2 main pump flow and 217 kN traction force make it a productive platform for hydraulic breakers, augers, grapples and other attachments in quarry, road and trenching work.

- Higher hydraulic flow — 240 L/min × 2 supports larger breaker classes and higher-torque augers
- Greater digging force — 169 kN bucket force vs. 144 kN in the 22-ton class
- Longer reach — 10,202 mm maximum digging reach for attachment work at distance
- Heavier carrier — better recoil absorption for breaker work and more stability for grapple handling
- Breaker and auger dealers in most regions are already familiar with Cummins service points
- Parts availability does not depend on a single regional distributor
- Downtime planning is predictable across markets
- Primary attachment(s) to be used
- Existing attachment pin dimensions (if quick coupler sizing needed)
- Bucket capacity requirement
- Hydraulic flow requirement of your attachments
- Destination port and transport constraints (25.4-ton machine)
When Attachment Performance Becomes the Buying Decision
At 25 tons, most buyers have already moved past the question of whether an excavator can dig. The question becomes: what else can it run productively?
The HT260 is configured for exactly that buyer. Behind its 1.4 m³ bucket and 169 kN digging force sits a hydraulic system specified to drive attachments that smaller machines cannot run at production rate.
The Hydraulic Numbers That Matter for Attachments
| Hydraulic Parameter | Value | Attachment Relevance |
|---|---|---|
| Main Pump | Kawasaki K7V125 | Proven flow stability under sustained attachment load |
| Maximum Main Pump Flow | 240 L/min × 2 | Supports large breakers, high-torque augers and grapples |
| Control Valve | Kawasaki | Consistent attachment response and metering |
| Swing Motor | Kawasaki | Stable material handling with grapple or thumb |
| Travel Motor | Doosan | 217 kN traction force for repositioning on uneven ground |
For attachment buyers, Kawasaki hydraulics are not a marketing detail. They are the reason cycle times hold up when a breaker runs continuously or an auger meets dense soil.
Application-to-Attachment Mapping
| Job Type | Recommended Attachment | HT260 Advantage |
|---|---|---|
| Rock excavation / quarry face | Hydraulic breaker | 152 kW Cummins + 240 L/min × 2 flow sustains breaker output without stalling |
| Foundation piers / post holes | Auger | 25.4-ton carrier provides downforce for dense or compacted soil |
| Pipe laying / trenching | 1.4 m³ bucket (standard) | 6838 mm depth; 10202 mm reach |
| Demolition / debris handling | Grapple / thumb | 11.1 rpm swing speed; 217 kN traction for uneven sites |
| Road construction loading | Bucket + breaker | 9673 mm digging height for truck loading; quick coupler switching |
| Land clearing | Grapple / rake | 16.7° gradeability; 600 mm track shoes for stability |
Why 25 Tons Is Different from 22 Tons for Attachments
If you are upgrading from a 22-ton machine, the HT260 delivers concrete attachment advantages:
Quick Coupler — Configure at Order
Hightop can supply the HT260 with a quick coupler matched to your existing attachment inventory (pin diameter, hydraulic requirements) or new attachments ordered alongside the machine. Coupler type, pin dimensions and hydraulic flow requirements are specified before production — not assumed.
Engine and Attachment Service Alignment
The Cummins 6BTA5.9 engine is one of the most widely serviced diesel platforms in export markets. For attachment users, this means:

HT260 Attachment & Tool Compatibility FAQ
Can the HT260 run a hydraulic breaker productively?
Yes. The HT260's Cummins 152 kW engine and Kawasaki K7V125 main pump deliver 240 L/min × 2 flow — sufficient for large breaker classes in the 25-ton range. Confirm the breaker model and oil flow requirement during quotation so Hightop can verify hydraulic compatibility.
What quick coupler options are available for the HT260?
Hightop can supply the HT260 with a quick coupler sized to your existing attachment inventory or new tools ordered with the machine. Provide pin diameter, attachment weight and hydraulic requirements during inquiry.
Can I use attachments from my 22-ton excavator on the HT260?
Compatibility depends on pin diameter, mounting width and hydraulic flow. The HT260 has higher flow (240 L/min × 2) than 22-ton class machines, so some attachments may need flow regulation. Share your attachment specifications with Hightop, and the team will confirm whether a direct fit or adapter coupler is required.
Does the HT260 come with a standard bucket or can I choose?
The standard configuration is a 1.4 m³ bucket. Alternative bucket capacities can be discussed based on material density and job type. Trenching buckets, grading buckets and other variants are available on request.
How long does it take to switch between bucket and attachment?
With a quick coupler installed, attachment changes typically take minutes rather than hours. The exact time depends on coupler type and hydraulic connection method. Hightop can advise on the most efficient setup for your workflow.
Can Hightop supply attachments together with the HT260?
Yes. Hightop can supply breakers, augers, grapples, thumbs and other attachments alongside the HT260, configured for compatibility before shipment. This avoids separate sourcing and ensures the hydraulic setup is correct from day one.
Is the Cummins engine compatible with attachments that require high hydraulic demand?
Yes. The Cummins 6BTA5.9 produces 152 kW at 2200 rpm with 655 Nm maximum torque — sufficient to drive the Kawasaki K7V125 pump at 240 L/min × 2 under continuous attachment load. Confirm the specific attachment's flow and pressure requirements during quotation.
