Features
4.8‑ton class zero‑tail‑swing compact mini crawler excavator, built‑in MR zero‑tail design, ideal for narrow‑site urban renovation, residential landscaping, utility trenching, basement construction and indoor factory‑demolition jobs.
Powered by Komatsu 4D88E four‑cylinder diesel engine, net power 28.9 kW, Tier‑3 mechanical configuration without complicated urea after‑treatment. Low fuel consumption, easy‑access spare‑parts, high reliability specially for rental fleets and small‑scale projects.
Genuine MR zero‑tail‑swing structure, counterweight never extends beyond track width during full rotation, avoids wall collision risk in narrow alleys and tight working zones. Standard dozer blade delivers great back‑filling and ground‑leveling performance, improves machine stability during digging and lifting operations.
Multiple front‑end configurations available. Standard boom‑arm matched with 0.16 m³ general‑purpose bucket efficiently handles earth‑moving and light‑breaking tasks. Optional offset boom supports trenching close to walls without repositioning the machine, adapts to various confined‑space construction requirements.
Closed‑center load‑sensing hydraulic system with dual pumps, selectable breaker working mode. Stable flow output supports long‑time operation of small‑size hydraulic breakers. Smooth compound movements and highly‑precise fine control fit delicate landscaping and municipal renovation work.
Reinforced heavy‑duty boom & stick assembly with fully sealed dust‑proof hinge pins, excellent anti‑deformation performance under frequent impact conditions, reduces oil‑leak risks and lowers overall failure rate.
Optional factory pre‑installed bi‑directional auxiliary hydraulic lines support breakers, grapples and tilt buckets without extra on‑site pipe modification, realizes fast multi‑attachment switching for diversified small‑works.
Spacious enclosed ROPS cab with good all‑round visibility, air‑conditioning optional for long‑shift comfort. Ergonomic joystick layout relieves operator fatigue during continuous daily operation.
All core daily‑maintenance check‑points are arranged for ground‑level access. Single‑operator completes routine inspection without climbing upper structures, shortens service time and minimizes jobsite downtime.
