KT-40 MINI EXCAVATOR
Product Overview
Welcome to our KT-40 Mini Excavator, a flagship 4-ton full zero-tail compact crawler digging machine equipped with complete high-flow load-sensing hydraulic assemblies. It comes standard with eight-section extended synchronous side-shift working arm, ultra-thick integrated front dozer blade and long-stroke hydraulically retractable widened undercarriage. Adopting full zero-swing structure without protruding counterweight at machine tail, the compact retracted dimension enables smooth passage through standard household doors, double underground parking garages, wide alleys in old communities and large multi-story indoor heavy demolition sites. After full track extension, the ground contact area expands greatly, delivering excellent anti-overturn performance during continuous heavy-duty deep excavation and rock breaking on muddy farmland, long gentle slopes, soft backfill and stony mine ground.
Fitted with heavy-duty universal hydraulic quick-change couplings, the machine can rapidly install large heavy hydraulic breakers, oversized tree augers, heavy log grapples, widened compaction rollers and deep ditching cleaning buckets, integrating ultra-deep digging, thick rock demolition, large-diameter rock drilling, large-area ground leveling and heavy material grabbing into one integrated unit. Compared with KT-35 and all smaller tonnage models, the KT-40 achieves full upgrades in overall weight, maximum extended chassis width, ultimate digging depth, ground working radius, thick solid cast iron counterweight and hydraulic flow & pressure. It is perfectly suitable for long-term high-load connected earthmoving and demolition projects including ten-thousand-mu large fruit orchards, full mountain landscapes, full multi-story indoor heavy demolition, medium-large municipal pipelines along urban main roads, connected large rural infrastructure and standardized large greenhouses. A single operator can carry out non-stop all-day heavy-duty construction, drastically boosting comprehensive efficiency for wide-area connected projects. As the flagship heavy micro construction equipment for landscape general contractors, super-large fruit farms, professional decoration groups, comprehensive municipal maintenance departments and large-scale planting bases, it provides long-lasting stable integrated medium and large earthmoving solutions.
Different from all mini excavators below 3.5 tons with narrow tracks and light counterweights, the KT-40 adopts ultra-wide extendable undercarriage and solid thick cast iron counterweight, fundamentally solving the tipping hazard on soft muddy and stony ground during long-hour heavy rock breaking. The eight-section extended side-shift zero-tail boom removes all dead zones beside walls and tree trunks, cutting down repeated machine relocation during ultra-long wide trenching tasks. The upgraded ultra-high-flow high-pressure hydraulic circuit supplies higher flow and peak pressure that can stably drive large heavy demolition attachments unavailable for smaller models. The dual-speed ergonomic pilot control balances fast site transfer and micron-level precise fine digging, lowering operator fatigue during all-day heavy shifts. The full modular pipeline protection layout reduces hydraulic abrasion and leakage on stony sites, while centralized maintenance points simplify daily inspection and component replacement to control long-term service costs. Comprehensive customized options meet diversified high-load construction demands across agriculture, landscape, municipal and indoor demolition industries.

Product Features
1.Ultra-wide Extended Tracks & Solid Thick Cast Iron Counterweight, delivering far larger ground contact area than all mini excavators under 4 tons to prevent side tipping during continuous digging and breaking on mud, gentle slopes and stony soft soil. The solid thick cast iron rear counterweight fully offsets torsion generated by eight-section long boom excavation, minimizing body shaking during all-day heavy rock breaking. Original thick wear-resistant rubber tracks protect tiles, lawns and asphalt surfaces without scratches; steel track assemblies are optional for mine and hard stony construction sites, with separate track spare parts available for later replacement and maintenance.
2.Eight-section Extended Side-shift Zero-tail Boom for Dead-angle Free Long-distance Ultra-deep Rock Digging Eight-stage extended working arm with dual synchronous left-right side shift and full zero-swing body, with no protruding counterweight at machine tail. It enables zero-distance excavation and rock breaking close to walls and tree trunks, completing ultra-long wide trenches in a single pass without frequent machine relocation, drastically raising efficiency in basements, narrow alleys and large yard corners for full-range wide-area connected deep excavation and rock breaking projects.
3.Ultra-high-flow High-pressure Load-sensing Hydraulic Quick-change System Seamlessly Matches Heavy Demolition Attachments The full set of ultra-high-flow high-pressure load-sensing hydraulic pipelines delivers fully upgraded system flow and peak pressure, which can stably drive large heavy hydraulic breakers and oversized tree augers for long-hour continuous work. Standard tool-free hydraulic quick couplings enable one-click fast replacement of buckets, grapples, compaction rollers and wide deep ditching buckets, covering excavation, thick concrete & thin rock breaking, seedling deep drilling and heavy stone grabbing with one machine.
4.Dual-speed Self-adaptive Ergonomic Pilot Control Balancing Transfer Speed & Micron-level Precision Digging Two adjustable travelling gears for free switching: high speed for long-distance site transfer to boost mobility efficiency, low precision mode for ultra-fine digging at wall corners and narrow ditches. The extended widened ergonomic dual pilot joysticks reduce hand fatigue during full-day heavy-duty shifts, and new staff can independently finish full deep digging and heavy rock breaking work within half an hour.
5.Ultra-thick Widened Integrated Dozer Blade for Synchronized Backfilling & Large-area Leveling Thickened reinforced integrated widened front dozer blade with upgraded plate thickness and rigidity synchronously backfills ultra-wide trenches and levels large yard areas during excavation, removing the need for extra manual ground finishing and drastically cutting auxiliary labor expenditure for ten-thousand-mu wide-area site transformation projects.
6.Full Pipeline Thickened Wear-resistant Protective Sleeve & Full Modular Integrated Layout with Ultra-low Failure Rate & Simple Maintenance All hydraulic pipelines are covered with thickened wear-resistant outer rubber protective sleeves to avoid abrasion and leakage on sand and stony construction sites. Filters, pins and hydraulic service points are centrally arranged for simple daily inspection and part replacement, keeping long-term maintenance expenditure under effective control.
7.Full-range Engineering Customization for All Medium & Large Connected High-load Working Conditions Customizable eight-section extended boom kits, bucket volume, track material and complete engineering attachments. OEM private labeling including customized body color, brand logos and equipment nameplates is supported.
