Product Overview

The HT40 is a 3.8-ton class mini crawler excavator built for professional B2B buyers who require the longest digging reach, strongest breakout force, and full Euro 5 / EPA4 emission compliance in a compact package. With an operating weight of 3810 kg, the HT40 bridges the gap between the mini excavator and full-size compact excavator categories — delivering exceptional capability while remaining narrower and lighter than traditional 4-ton machines.

At the heart of the HT40 is the globally proven Kubota D1703 engine — a three-cylinder, water-cooled, naturally aspirated direct-injection diesel delivering 18.5 kW (25 HP) @ 2200 RPM with a peak torque of 97.4 N·m @ 1500 RPM. Fully certified to Euro 5 and EPA4, the HT40 meets the most stringent emission regulations required for import into the EU, UK, USA, Australia, Japan, and other regulated markets — making it the ideal choice for distributors serving environmentally-conscious buyers.

The HT40’s key differentiator is its exceptional working envelope: a 5480 mm maximum digging reach (longest in the HT series), 4800 mm digging height, and 3208 mm digging depth, combined with a boom swing function (Left 55° / Right 65°) for precision work alongside walls and structures. An ultra-low ground pressure of 32 kPa from its 300 mm wide track shoes ensures minimal surface damage on soft terrain and sensitive work sites.

6 Reasons to Choose the HT40

🌍 Euro 5 / EPA4 — Global Market Ready

The HT40 is certified to Euro 5 (EU/UK) and EPA4 (USA) emission standards — the two most demanding regulations globally. Distributors can import and sell into virtually any regulated market without further engine modification or retrofitting. This certification adds significant resale value and simplifies compliance documentation.

📏 5480 mm — Longest Reach in HT Series

At 5480 mm maximum digging reach, the HT40 sets the benchmark for horizontal range in Shandong Hightop’s entire product range. This extraordinary reach allows operators to work across ditches, reach under overhangs, and cover wider job footprints without repositioning — dramatically improving productivity on open sites.

💪 30.4 kN Breakout Force

With 30.4 kN bucket breakout force and 18.2 kN arm digging force at 22.5 MPa system pressure, the HT40 handles compacted clay, hard-packed gravel, light rock, and frozen ground that smaller machines cannot penetrate. This force rating makes it suitable for heavy-duty earthmoving on professional construction sites.

🔄 Boom Swing L55° / R65° — Precision Work

The asymmetric boom swing range (55° left / 65° right) enables precision trench digging parallel to walls, fences, and structures. Operators can reposition the work tool without moving the machine, reducing setup time and enabling access to tight angles that fixed-boom machines simply cannot reach.

🪶 32 kPa Ground Pressure — Surface Protection

The extra-wide 300 mm track shoes spread the machine’s weight across a large contact area, generating only 32 kPa ground pressure. This is low enough to operate on soft ground, wet terrain, landscaped lawns, and lightly paved surfaces without excessive rutting or damage — expanding the range of viable job sites significantly.

🏠 Standard Enclosed Cab + Multiple Colors

The HT40 ships with a standard ROPS/FOPS enclosed cab for all-weather operation. Multiple factory paint colors are available as shown in the product’s color swatch, plus custom RAL color matching for OEM private-label orders. CE / EPA / ISO 9001 certificates provided for all export destinations.

Application Scenarios

🏗 Road & Infrastructure

Deep trench excavation, culvert installation, drainage channel construction, utility burial, and site preparation — the HT40’s 3208 mm digging depth and 30.4 kN breakout force handle demanding civil infrastructure projects.

🌿 Landscaping & Agriculture

Pond excavation, drainage installation, terracing, tree planting pits, and irrigation trenching. The 32 kPa ground pressure protects lawns and soft agricultural land while the 5480 mm reach covers wide planting beds and water features without repositioning.

🏚 Demolition Preparation

Light structural removal, foundation breaking, rubble clearing, and site stripping. The boom swing function allows work alongside standing walls while the high breakout force tackles reinforced concrete slabs and compacted fill material.

⚡ Utility Service Work

Water main installation, gas line burial, fiber cable trenching, sewer repair, and electrical conduit laying. Boom swing function enables precision digging in narrow utility corridors; dual-speed travel allows rapid repositioning between service points.

🏢 Commercial Construction

Strip footing excavation, basement preparation, retaining wall base trenching, and tight-access site work. The 5480 mm reach and boom swing combination enables complete site coverage even in constrained urban plots with multiple obstacles.

🚜 Rental Fleet Operators

The HT40’s Euro 5 / EPA4 certification, wide application versatility, enclosed cab, and proven Kubota reliability make it a high-utilization rental machine. One unit can serve road builders, landscapers, utility contractors, and construction sites — maximizing rental return per asset.
