KT-50 MINI EXCAVATOR
Product Overview
Welcome to our KT-50 Mini Excavator, a flagship 5-ton full zero-tail compact crawler digging machine equipped with full sets of ultra-high flow load-sensing hydraulic assemblies. It comes standard with nine-section extended synchronous side-shift working arm, ultra-thick widened integrated dozer blade and ultra-long large-stroke hydraulically retractable track chassis, adopting an integrated zero-swing structure without any protruding counterweight at machine tail. The machine maintains compact retracted dimensions that can smoothly pass standard household doors, double underground parking garages, wide alleys in old residential blocks and large multi-story indoor heavy demolition sites. After full track extension, the ground contact area reaches top-tier level within the same tonnage range, delivering outstanding anti-overturn performance during continuous heavy-duty deep digging and rock breaking on muddy farmland, long gentle slopes, soft backfill soil and stony mine sites.
Fitted with heavy-duty universal hydraulic quick-change couplings, the machine can rapidly install extra-large heavy hydraulic breakers, oversized tree augers, heavy log grapples, widened compaction rollers and deep ditching cleaning attachments, integrating ultra-deep excavation, thick rock heavy demolition, large-diameter rock drilling, large-area ground leveling and heavy material grabbing in one integrated unit. Compared with KT-40 and all smaller tonnage models, the KT-50 realizes comprehensive leap-forward upgrades in overall weight, maximum extended chassis width, ultimate digging depth, ground working radius, solid cast iron rear counterweight and hydraulic flow & pressure output. It is perfectly suitable for high-intensity long-term connected earthmoving and demolition projects including ten-thousand-mu large contiguous fruit orchards, full mountain landscape renovation, full multi-story indoor heavy full demolition, medium-large municipal pipelines along urban main roads, connected large rural infrastructure and standardized ultra-large greenhouses. A single operator can carry out non-stop all-day heavy-duty construction, drastically boosting overall efficiency for wide-area connected projects. It serves as the top flagship heavy micro construction equipment for landscape general contractors, ultra-large ten-thousand-mu fruit farms, professional decoration engineering groups, municipal comprehensive maintenance departments and large-scale ten-thousand-mu planting bases, providing long-lasting stable integrated medium and large earthmoving & demolition comprehensive solutions.
Different from all mini excavators below 4 tons with narrow tracks and light cast iron counterweights, the KT-50 adopts ultra-wide extendable undercarriage and solid thick cast iron rear counterweight, fundamentally solving the tipping hazard on soft muddy ground during long-hour heavy breaking and deep excavation. The nine-section extended side-shift zero-tail boom eliminates all dead zones beside walls and tree trunks, cutting down repeated machine relocation during ultra-long wide trenching tasks. The leap-upgraded ultra-high-pressure high-flow load-sensing hydraulic circuit supports extra-large heavy breaking attachments that cannot be matched by lower-tonnage models. The dual-speed ergonomic pilot control balances fast site transfer and ultra-precise fine digging, effectively lowering operator fatigue during all-day shifts. The modular pipeline protection layout reduces hydraulic abrasion and leakage on stony construction sites, while centralized maintenance points simplify daily inspection and component replacement to control long-term service costs for large construction teams. Comprehensive customization options meet diversified construction demands across agriculture, landscape, municipal and large indoor demolition industries.

Product Features
1.Top-tier Ultra-wide Retractable 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 deep digging and breaking on muddy farmland and long gentle slopes. The solid thick cast iron rear counterweight fully offsets strong torsion generated by nine-section long boom excavation, minimizing body shaking during all-day continuous heavy breaking. Original thick wear-resistant rubber tracks protect tiles, lawns and asphalt surfaces without scratches; steel track assemblies are optional for mine and stony construction sites, with separate track spare parts available for later replacement.
2.Nine-section Extended Side-shift Zero-tail Boom for Dead-angle Free Long-distance Ultra-deep Rock Digging Nine-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 close to walls, tree trunks and fences, 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 large connected deep excavation and heavy rock demolition projects.
3.Ultra-high-pressure High-flow Load-sensing Hydraulic Quick-change System Seamlessly Matches Extra-large Heavy Breaking Attachments The full set of ultra-high-pressure high-flow load-sensing hydraulic pipelines delivers leap-upgraded system output flow and peak pressure, which can stably drive extra-large heavy hydraulic breakers and oversized tree augers. Standard tool-free quick hydraulic couplings enable one-click fast replacement of buckets, heavy grapples, compaction rollers and wide deep ditching buckets, covering excavation, thick concrete & hard rock heavy demolition, seedling deep drilling and heavy stone grabbing with one machine.
4.Dual-speed Self-adaptive Ergonomic Pilot Control Balancing Transfer Efficiency & 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 fine digging at wall corners and ditches. The ergonomic extended dual pilot joysticks reduce hand fatigue during full-day heavy-duty shifts, and new operators can independently finish full deep digging and heavy rock demolition work within half an hour.
5.Ultra-thick Widened Integrated Dozer Blade for Large-area Synchronized Backfilling & Leveling Thickened reinforced front dozer blade with upgraded plate thickness and rigidity synchronously backfills ultra-wide trenches and large ground areas during excavation, eliminating extra manual ground finishing procedures and drastically cutting auxiliary labor expenditure for ultra-large connected 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 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 component replacement, keeping long-term maintenance costs under effective control.
7.Full-range Engineering Customization for All Medium & Large Connected High-load Working Conditions Customizable nine-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. Exclusive tailor-made machines can be developed for large-scale agriculture, landscape, municipal and large indoor demolition dedicated ultra-large projects.
