Compact 2 Ton Excavator

The HT-20U mini excavator is built around one simple idea: when the work happens in a tight space, the machine itself should disappear. With a 662 mm tail radius, the upperstructure rotates fully inside the track footprint, so the HT-20U can work flush against walls, foundations, fences, and inside greenhouses without the operator ever needing to look back. A 998 mm upper width combined with a chassis that retracts from 1,011 mm to 1,320 mm gives the same machine two personalities: narrow enough to slip through a 1 m doorway, wide enough for stable grading on open ground. The HT-20U joins Hightop's mini excavator lineup, sharing attachment interfaces and service support with the rest of the compact family.

Compact dimensions do not mean compact performance. The HT-20U delivers a 2,042 mm maximum digging depth, a 3,276 mm digging height, and a 3,780 mm working reach — true excavator numbers in a 1,650 kg package. Power comes from an 11.8 kW diesel paired with a load-sensing variable displacement hydraulic pump (Rexroth A10VO28, 2–28 cc/r, 53 L/min system flow). Unlike fixed-volume gear pumps, the piston unit only delivers flow on demand, so engine RPM, fuel consumption, and heat build-up all stay low during the long idling periods typical of trenching and landscaping work. Selectable travel speeds (2.1 / 4.3 km/h) let operators creep precisely into a dig or reposition quickly across a site.

The result is a machine tailored for rental fleets, urban contractors, and specialty crews. Pair the HT-20U with our mini excavator attachments — narrow buckets, hydraulic hammers, augers, grapples, and rakes — to handle trenching, landscaping, foundation work, and pipe-laying on the same job. For crews that need slightly more weight and reach, the 2 ton mini excavator HT20 sits one step up in the same Hightop micro-class family.

Mini Excavator 2 Ton With Variable Piston Pump Product Features

  1.  Zero-Tail Swing Design, 662 mm Tail Radius:The upperstructure stays within the track footprint at full rotation, so the HT-20U works against walls, in corners, and indoors without rear swing danger — and without the operator constantly checking mirrors or machine corners. 
  2. Variable Displacement Piston Pump:The Rexroth A10VO28 load-sensing piston pump only produces flow when the joystick demands it. Engine speed, fuel use, and hydraulic-oil temperature all drop during idle, giving longer service intervals and lower lifetime operating cost.
  3. Retractable Track Frame, 1,011–1,320 mm: A single chassis pulls in to pass through doorways, garden gates, and greenhouse aisles, then pushes out for stable grading and digging. No tools required, no extra machines needed. 
  4. 30 kPa Ground Pressure:Among the lowest in the Hightop mini excavator range — kinder to finished lawns, pavers, sports turf, and indoor floors than wheeled equipment or larger tracked machines. 
  5. Two Selectable Travel Speeds,2.1 / 4.3 km/h: Low range for precise trenching, grading, and loading; high range for moving across open yards. Operators switch on the fly without tools. 
  6. 16 kN Bucket / 9.5 kN Arm Breakout: Productivity stays high for a 1.65-ton class machine — trench walls stay clean, post holes go in one pass, and tamped soil breaks up without ramping.
  7. Multiple Attachment Interfaces : Standard boom pin layout accepts narrow bucket, hydraulic hammer, auger, grapple, rake, and tree shears — the same attachment family used across the Hightop micro class.

Mini Excavator 2 Ton With Variable Piston Pump HT20U  Application Scenarios

1. Indoor Renovation & Basement Digouts:The 998 mm upper width and zero-tail swing let the HT-20U pass through standard doors and work inside buildings — stairwell cores, basement extensions, indoor pool construction — where diesel exhaust must be managed through a hose. 

2. Urban Utility & Pipe Trenching: With 2,042 mm digging depth and a 662 mm tail, the HT-20U runs water, gas, and fiber lines along sidewalks and alleys without closing lanes or damaging adjacent structures.

3. Landscaping & Garden Construction: Low30 kPa ground pressure protects finished lawns, paving stones, and irrigation lines. Retract the undercarriage to 1,011 mm to roll through a 1-meter garden gate without removing the fence. 

4. Greenhouse & Nursery: Zero-tail rotation works between planting rows without damaging adjacent beds. The 1,650 kg weight and230 mm tracks distribute load on prepared greenhouse floors. 

5. Rental Fleets & Multi-Site Contractors: The Kubota engine, common hydraulic interfaces, and Hightop parts commonality make the HT-20U simple to maintain across mixed fleets — exactly what rental operators ask for.

Shandong Hightop Group Service Support

Hightop backs every1.65 ton mini excavator with a support network tuned to the realities of micro-class ownership — not a generic heavy-machinery template.

① Micro-Class Container Loading 

At 1,650 kg and 3,582 mm length, multiple HT-20U units pack into a single 20 ft container — typically three machines plus a partial attachment set in one box. This dramatically lowers per-unit shipping cost for fleet buyers and rental operators building inventory. Rust-proofed export packaging, full documentation, and FOB / CIF / DDP terms are standard.

② Cross-Model Spare Parts Compatibility

Filters, seals, track components, and hydraulic fittings for the 1.65-ton class share part numbers across the Hightop micro excavator family. A single parts inventory covers HT-10B, HT20, HT-20U, and similar compact machines — simplifying stockholding for rental yards and multi-model dealers.

③ Rental-Fleet Customization

Volume buyers — rental companies, municipal fleets, large contractors — receive factory-direct livery customization (paint, decals, fleet numbering), pre-fitted attachment packages, and consolidated container loading. Speak with our sales team about fleet pricing tiers.

④ Warranty & Rapid Engineering Response

Every machine ships with a documented standard warranty. When issues arise, reach us by WhatsApp, email, or video call — engineering support responds within 24 hours, including remote diagnostics, so downtime stays in hours, not weeks.

Mini Excavator 2 Ton With Variable Piston Pump FAQs

Q1: What does "zero-tail" or "no-tail" mean on the HT-20U? 

It means the upperstructure rotates entirely inside the track footprint — at full rotation, no part of the machine sticks out beyond the tracks. The 662 mm tail radius is the actual swing clearance; compare this to mini excavators that overhang 700 mm or more, which require an extra meter of clearance to work against a wall. 

Q2: What is the operating weight, and how do I transport it?

 Operating weight is 1,650 kg. It can be towed on a standard light-truck trailer (2–3 ton class), loaded by ramp, and shipped in 20 ft or 40 ft containers — see the logistics section above for container math. 

Q3: How is a variable piston pump different from a gear pump? 

 A gear pump outputs a fixed volume per revolution regardless of demand — so engine RPM stays high and fuel burns even when the joystick is centered. A load-sensing piston pump only produces flow when the operator commands a movement, which lowers fuel use, oil temperature, and noise during long idle-heavy tasks like trenching and landscaping. Over the life of the machine, the piston pump also reduces hydraulic-oil change intervals. 

Q4: What attachments fit the HT-20U?

Standard quick-coupler attachments across the Hightop micro class — narrow buckets (200 / 300 / 400 mm), hydraulic hammer, auger (100–300 mm), grapple, rake, tree shears, and rotary trench cleaner. All use the same pin geometry as the HT10 / HT-10B / HT20 family for shared fleet inventory. 

Q5: What warranty and after-sales support is included? 

Standard warranty with documented claims process, English operation & service manuals, WhatsApp / email / video-call engineering support with 24-hour response, and lifetime supply of common spare parts (filters, seals, track components). CE / EPA compliance documentation is included for export shipments.
