Features
21.7‑ton proven reliable long‑undercarriage medium crawler excavator, widely popular for municipal construction, foundation digging, site grading, highway works, quarry secondary breaking and general earth‑moving projects.
Equipped with original Cat C6.4 ACERT six‑cylinder turbo after‑cooled diesel engine, rated power 103 kW, meets Tier 3 / Stage IIIA emission standard. ADEM A4 electronic control optimizes combustion performance, automatic engine speed control lowers fuel consumption, stable output for long‑time continuous jobsite operations, well‑adapted to poor‑quality fuel in remote regions.
Reinforced LC long‑track undercarriage with heavy‑duty track rollers, thickened track links and triple‑grouser wear‑resistant track shoes. Optimized ground‑pressure distribution delivers solid stability during digging and truck‑loading cycles, extends service‑life under abrasive and muddy working‑site environments.
Standard boom‑arm assembly matched with 0.9‑1.13 m³ general‑purpose or rock bucket provides powerful breakout force for hard‑soil excavation and blasted‑rock material handling. Optional short breaking arm and long‑reach front adapt to rock‑breaking, deep trenching and slope‑shaping assignments.
Mature load‑sensing hydraulic system with total max flow up to 404 L/min, adjustable power modes and one‑touch power‑boost function. Short work‑cycle time, supports continuous operation of medium‑size hydraulic breakers, guarantees smooth compound movements and precise fine‑control performance.
High‑strength reinforced boom & stick with full‑penetration reinforced welds and oversized heavy‑duty pins & bushings. Robust structural design resists frequent rock impact and abrasion, reduces oil‑leak failures and minimizes unplanned downtime for round‑the‑clock construction‑site shifts.
Factory‑fitted bi‑directional auxiliary hydraulic piping supports hydraulic breakers, grapples and quick couplers without extra on‑site pipe modification. Multi‑attachment compatibility fulfills diversified earth‑moving, demolition and rock‑breaking tasks.
Spacious ROPS‑FOPS certified operator cab with vibration‑damping mounts, multi‑language display, rear‑view camera and automatic air‑conditioning. Cat Product Link telematics enables remote tracking of working hours, fuel consumption and fault codes for efficient jobsite fleet management.
Key daily‑maintenance service points adopt ground‑level side‑access layout. Operators complete fluid replacement and filter servicing without climbing upper structures, saving routine‑maintenance time and cutting overall operating costs.
