HT18-3 Mini Excavator – 1.8T, 2.06m Dig Depth

  • 1,800 kg operating weight
  • Kubota D722 or Koop 292 diesel options
  • 2,060 mm digging depth
  • 790 mm tail swing radius

When Your Job Site Measures in Centimetres, Not Metres

You are trenching behind a commercial building where the alley leaves you barely any room to manoeuvre. Or digging footings between two existing walls on a tight renovation. Or clearing a slope where the machine needs to stay stable while the arm reaches out at an awkward angle. The full-size excavator cannot get in. The shovel means losing the day. You need a machine that slides through tight access and still delivers real digging power. That is exactly what the HT18-3 was built to do.

What 1,800 kg Means for Your Daily Operations

At just under two tonnes, this excavator sits comfortably on a standard tandem-axle trailer behind a 1-ton pickup. No special hauling permits. No waiting for a lowboy delivery. You load it in the morning, work a residential job by 8 AM, and move to the next site by afternoon. For small to medium contractors running multiple jobs per week, that mobility is what keeps overhead low and schedules tight. The compact footprint also means less ground disturbance – a detail landscapers and property owners notice immediately.

Two Engine Options That Match Your Market

The HT18-3 comes with your choice of power. The Kubota D722 is the industry benchmark – a 3-cylinder, 10.2 kW diesel that starts reliably in cold weather and sips fuel through long days. For markets where parts availability favours domestic brands, the Koop 292 delivers 14 kW of equivalent performance with the same mounting configuration. Both options deliver consistent, fuel-efficient power across a full day of trenching, grading, and loading. No complex aftertreatment systems that add maintenance headaches. Just turn the key and work.

The Boom Swing That Changes How You Approach Obstacles

Standard equipment on this machine includes a boom that swings 75° to the left and 45° to the right. That means you can dig parallel to a foundation, trench along a fence line, or excavate against a retaining wall without constantly repositioning the entire machine. For operators working in tight urban lots, narrow alleys, or between existing structures, this feature alone can cut cycle times by 20 to 30 percent. You spend less time manoeuvring and more time moving material.

The 790 mm Tail Swing That Keeps You Out of Trouble

With a tail swing radius of just 790 mm, the HT18-3 lets you work against walls, foundations, and obstacles without worrying about the counterweight smashing into finished surfaces. This is not a feature you appreciate until you have spent a day manoeuvring around existing structures on a renovation site. For operators working in tight urban lots, narrow alleys, or indoor demolition sites, this compact tail swing alone can cut cycle times by eliminating constant repositioning.

Hydraulics That Deliver When You Need Them

The HT18-3 is equipped with a hydraulic system featuring a BEIFANG main valve that ensures smooth, responsive control. Bucket digging force and arm force are balanced for consistent performance through compacted soil, clay, and root-bound ground. The swing motor rotates at 12 RPM, giving you quick cycle times when you are loading a trailer or stacking spoils. The controls are responsive and precise – whether you are feathering the bucket for a precision trench alongside a foundation or applying full breakout force to break through tough material.

Working Range That Surprises First-Time Owners

This machine reaches out to 3,160 mm from the swing centre and digs down to 2,060 mm – enough for trenching utility lines, footings, and drainage systems. Maximum dumping height is 1,637 mm, which clears the side of most standard dump trailers. Maximum digging height reaches 2,580 mm. With a minimum turning radius of 1,711 mm, you can work in tight corners without wasting time on multi-point turns. The 30° gradeability handles sloped driveways, ramp loading, and uneven terrain without losing traction.

Where This Excavator Actually Belongs

We see HT18-3 units working everywhere from backyard landscaping and greenhouse maintenance to indoor demolition inside warehouses and light commercial construction. The compact 1,100 mm overall width and 790 mm tail swing radius let it navigate through standard doorways, alleys, and pallet racking aisles with ease. The 200 mm rubber tracks with a 1,050 mm ground contact length deliver low ground pressure for steady operation on uneven or soft surfaces. For rental fleets and owner-operators alike, this machine adapts to the job – not the other way around.

Maintenance That Keeps You Working, Not Waiting

Service points are designed for accessibility. The engine oil drain, fuel filter, and air cleaner are grouped for quick daily checks. Daily greasing of the boom, arm, and bucket pins takes minutes with a standard hand pump. The 119 mm minimum ground clearance handles uneven terrain and job site debris without dragging the undercarriage. For overseas customers, we stock common wear parts – tracks, pins, bushings, filters – in regional warehouses, so you are not waiting weeks for a simple replacement.

Does the HT18-3 meet EPA and CE certification for the US and European markets?
Yes. The Kubota D722 engine option is available with EPA Tier 4 / Stage V compliance for North American and European markets. The Koop 292 option can be configured for other regions. We provide the necessary certificates for customs clearance in the US, EU, Australia, and most other major markets. If your country has specific local requirements, we can adjust the documentation package accordingly.
Will this excavator fit through a standard residential gate or commercial doorway?
With an overall width of 1,100 mm (approximately 43.3 inches), the HT18-3 is designed for standard double gates, commercial doorways, greenhouse entrances, and pallet racking aisles. For tighter residential access – such as standard 36-inch garden gates – we recommend checking the exact opening width, as this machine is slightly wider than that dimension. The 790 mm tail swing radius makes it especially effective for tight maneuvering once inside.
What attachments can I run on this excavator?
The HT18-3 accepts standard pin-on attachments including buckets, augers, hydraulic breakers, and grading beams. Common configurations include a trenching bucket for utility work, a post-hole auger for fencing, and a breaker for light demolition. All attachments are available as optional extras and can be bundled with your initial order.
What jobs is this machine NOT suitable for?
The HT18-3 is not designed for heavy rock excavation, deep basement digging beyond 2 metres, or continuous production loading in mining applications. It excels at trenching, landscaping, site cleanup, utility work, light demolition, greenhouse maintenance, and confined-area construction. For heavy-duty applications with larger bucket capacities and higher breakout forces, we recommend stepping up to the HT20 or HT25 series.
