Product Features

• The machine is fitted with a 2600mm customized standard stick matched with a multi-spec bucket assembly system; apart from the standard 0.9m³ bucket, users can replace small digging buckets, loading buckets and rock buckets to adapt diversified construction tasks.

• The cab adopts a fully enclosed wide-view structural design with 360° transparent glass and shock-absorbing suspension seat; it isolates construction noise and reduces bump fatigue during long-time driving and operation.

• Independent front dozer blade assembly is preset on the front frame, with 2400mm blade width and 1345mm front overhang; it can level ground, stabilize the body during single-side deep excavation and backfill shallow trenches.

• The whole vehicle’s upper and lower frames are made of thickened wear-resistant manganese steel, with full welding reinforcement at stress points such as boom connection and wheel support to extend the service life of structural parts.

• The machine reserves complete external hydraulic quick-change interfaces, supporting quick connection of auxiliary attachments including breaking hammers, grab buckets and augers to expand multifunctional construction capacity.

Targeted Construction Solutions

Urban Municipal Road Renovation

Scene: Downtown road reconstruction narrow construction zone | Pain point: Traditional crawler excavators scratch pavement and need trailer transfer with high fees | Matching function: Wheel type 0~28km/h self-driving travel, non-damage rubber tires | Result: Cut pavement repair compensation and trailer rental cost by over 30%, finish road reconstruction faster.

Underground Pipeline Trenching

Scene: Urban water & power pipeline laying project | Pain point: Insufficient digging depth and weak digging force slow down trenching progress | Matching function: 120kN bucket digging force, 5915mm max digging depth | Result: Complete deep trench excavation in one pass, shorten pipeline construction cycle.

Highway Earthmoving & Landscaping

Scene: Suburb highway backfilling and park landscaping | Pain point: Limited horizontal reach requires repeated machine relocation | Matching function: 9615mm max horizontal reach, 6900mm high dumping height | Result: Reduce machine moving frequency, raise daily earthmoving output significantly.
