HT18-2 Mini Excavator – Retractable Tracks for Narrow Access

When the Job Site Gives You Barely a Metre to Work With

You are trenching for a drainage line behind a commercial strip where the alley is just over a metre wide. Or digging footings between two existing foundations on a renovation. Or clearing a slope where the machine needs to stay stable while the arm reaches out at an angle. The full-size excavator cannot get in. The shovel means losing the day. You need a compact machine that turns tight access into a working advantage. That is what the HT18-2 was built to do.

What Retractable Tracks Mean for Your Daily Operations

The HT18-2 features a retractable undercarriage with a chassis width of 1,050 mm when narrowed for transport or access, then widens to a stable operating stance once you reach the work area. This means you can move between job sites on a standard trailer behind a 1-ton pickup, pass through tight gateways without dismantling anything, and still have the stability to dig confidently once you are in position. No special hauling permits. No waiting for a lowboy delivery. Just hook up, move, and work.

Power That Matches the Job, Not the Other Way Around

Under the canopy sits your choice of two 39 HP diesel engines – the Kubota D1105 or the Laidong 3TE25. Both deliver consistent, fuel-efficient power across a full day of trenching, grading, and loading. The Kubota D1105 delivers 14.2 kW and is the industry benchmark for reliability and cold-weather starting. The Laidong 3TE25 pushes 18.4 kW of equivalent performance with the same mounting configuration. Both options meet Euro 5 and EPA emission standards – critical for contractors working in North America and Europe where emissions compliance is non-negotiable. No complex DPF regeneration cycles. Just turn the key and work.

The Boom Side Swing That Changes How You Approach Obstacles

Standard equipment on this machine includes a boom side swing function with a deflection angle of 35° left and right. This allows you to dig parallel to a foundation wall, 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, orchards, 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.

Hydraulics That Deliver When You Need Them

The HT18-2 is equipped with a hydraulic system that delivers 18 MPa of working pressure with a standard bucket capacity of 0.06 m³. Bucket digging force comes in at 14 kN, with 10 kN of arm digging force – enough to break through compacted soil, clay, and root-bound ground. The swing motor rotates at 10 to 12 RPM, giving you quick cycle times when you are loading a trailer or stacking spoils. The machine is also equipped with a plunger travel motor with high and low speed functions – low speed delivers maximum torque when you are climbing onto a trailer or working through tough terrain, while high speed keeps travel efficient across flat job sites. The controls are responsive and precise, allowing feather-light adjustments for grading and heavier inputs for breaking.

Working Range That Surprises First-Time Owners

This machine reaches out to 3,860 mm from the swing centre and digs down to 2,050 mm – enough for trenching utility lines, footings, and drainage systems. Maximum dumping height is 2,385 mm, which clears the side of most standard dump trucks and trailers. Vertical digging depth reaches 1,725 mm, useful for straight-wall excavations. The 35° gradeability handles sloped driveways, ramp loading, and uneven terrain without losing traction. With a tail swing radius of just 1,125 mm and a minimum swing radius of 1,720 mm, you can work in tight corners without wasting time on multi-point turns.

Where This Excavator Actually Earns Its Keep

We see HT18-2 units working everywhere from backyard landscaping and greenhouse maintenance to indoor demolition inside warehouses and light commercial construction. The compact chassis and retractable tracks make it ideal for orchard work where you need to dig planting pits without damaging root systems. In municipal settings, it handles trenching for cable laying and road repair with minimal disruption to surrounding traffic. For landscapers, it shapes terrain, digs tree pits, and finishes water features without leaving ruts behind. The 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 230 mm rubber or steel track options give you flexibility depending on your terrain – rubber for asphalt and finished surfaces, steel for rocky and abrasive conditions. 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.
