III. Power System Configuration
Engine Model: Imported turbocharged diesel engine with National IV emission standard
Power Characteristics: Low speed with high torque, fast power response, strong adaptability to high-temperature and high-altitude working conditions
Emission System: Standard National IV after-treatment system, no speed limit failure and low maintenance requirements, fully compliant with construction site environmental inspection standards
Fuel Economy: G-series intelligent fuel-saving calibration reduces comprehensive fuel consumption by 10%–15% compared with old models, effectively lowering long-term operating costs
IV. Hydraulic & Intelligent Control System
Hydraulic System: Matched with high-flow main pump and valve group of 220-level, providing sufficient flow and coordinated actions for pressurizing, lifting and slewing operations
Intelligent System: Equipped with the 4th-generation ROADS intelligent control system, realizing dynamic torque matching, automatic pressure stabilization and adaptive working condition adjustment
Functional Configuration: Supports fast pressurization, idle stroke acceleration, intelligent hole collapse prevention, automatic verticality correction and fault self-diagnosis
Operation Performance: Precise and sensitive control response, no engine stall or vibration during rock drilling, ensuring excellent construction stability
V. Structural & Chassis Configuration
Luffing Structure: Dual-cylinder supporting luffing system with high structural rigidity, strong anti-deflection capacity and high stability during deep-hole and hard rock drilling
Crawler Chassis: Extended and widened heavy-duty crawler with low ground pressure, ensuring excellent trafficability on muddy, soft and uneven sites with stable operation
Drill Rod Advantages: High-torsion mechanical lock rod with reliable locking performance, effectively preventing slipping and abrasion during long-term hard rock drilling
Integrated Transport Design: Optimized overall structure allows direct flatbed transportation with rod installed, eliminating rod disassembly and assembly procedures and greatly reducing transition costs and component loss
VI. Working Condition Adaptability
Applicable Strata: Backfill soil, clay, sand, pebble layer, strongly weathered rock and moderately weathered rock composite strata
Applicable Projects: High-rise building pile foundations, factory foundations, municipal bridges, photovoltaic power stations, retaining support piles and small-scale foundation reinforcement projects
Construction Features: Fast drilling speed, accurate verticality, low hole collapse rate and high-quality pile forming after concrete pouring
VII. Core Equipment Advantages
Low-hour Premium Condition: Manufactured in 2023 with only 1,500 light-duty working hours. The whole machine has minimal wear, and core hydraulic, power and transmission components are in peak condition with near-new performance.
Powerful Rock Drilling Capacity: The original mechanical lock rod delivers rigid torque transmission, stronger rock penetration than friction rods, no slipping in hard rock conditions and wider construction adaptability.
Efficient Integrated Transition: Supports full-process transportation with drill rod installed, no disassembly or re-calibratio n required, greatly improving site entry efficiency and reducing wear loss.
National IV Full Compliance: Latest National IV emission standard with complete legal procedures, unrestricted nationwide registration and high residual value stability.
High Efficiency & Low Fuel Cost: Matched with G-series intelligent fuel-saving system and high-torque power output, ensuring high construction efficiency and economic fuel consumption, ideal for high-return leasing projects.
High Durability & Low Maintenance Cost: As a mature benchmark model of ZOOMLIONION, the ZR180G enjoys large market stock, universal spare parts, low failure rate and stable long-term operation with low overall maintenance costs.
