SDLG Wheeled Excavator EA775H

Product Description

Reliability

Custom Yuchai turbocharged engines exclusively for SDLG deliver robust power while complying with China National Stage IV emission standard, balancing powerful performance and eco-friendliness. You can operate fully compliantly even under severe working conditions, capable of handling all types of construction tasks steadily.

Matched with high-torque reinforced transmission and 8-ton heavy-duty planetary drive axles, the machine boasts exceptional load-bearing capacity to sustain heavy-duty operations. Core components extend service life and cut replacement costs, with proven durability validated through long-term field tests.

All structural components are optimized via finite element analysis and subjected to high-load endurance testing, with critical sections reinforced. The machine maintains stable performance under intensive long-hour operation on complex job sites, minimizing breakdowns and delivering long-lasting reliability.

Hydraulic piping manufactured to international standards features upgraded sealing performance, fundamentally eliminating fluid leakage issues. It reduces unplanned downtime, ensures consistent machine operation and seamless workflow continuity.

High Efficiency

Adopting SDLG proprietary power matching technology, the powertrain, transmission and hydraulic system operate in seamless synergy to boost overall productivity, ideal for high-intensity continuous construction work.

The newly upgraded load-sensing hydraulic system enables coordinated, precise compound movements with ultra-smooth fine control. It accelerates working cycles and shortens single operation loop time to elevate productivity to a new level.

Combination of large-bore main control valve, high-displacement main pump and swing motor delivers enhanced lifting force and swing torque. Working efficiency is lifted by 10% compared to previous generations, helping users break through output bottlenecks rapidly.

Dual-balanced hydraulic suspension with 100mm travel stroke ensures all four wheels stay grounded even on muddy and rough terrain, delivering outstanding off-road capability to adapt to complicated ground conditions.

Fuel Economy

Electronically controlled common rail engines paired with ECU intelligent fuel injection maximize combustion efficiency to cut unnecessary fuel consumption, delivering remarkable fuel savings, lowering operating expenses and raising overall equipment cost-performance ratio.

Electronically controlled pumps coordinate intelligently with engine speed, plus automatic idle function, to precisely match power output to working demands and slash fuel consumption, balancing high productivity and superior fuel efficiency.

High-efficiency hydraulic components combined with redesigned oil passages reduce system pressure loss and improve energy conversion efficiency, further curbing fuel expenditure and generating substantial fuel cost savings for operators.

Operator Comfort

The brand-new wide-body cab features a reinforced frame, industry-leading NVH control technology and automotive-grade sealing & noise reduction processes, creating a quiet, dust-free working environment.

The air conditioning system is optimized via fluid mechanics simulation, with ergonomically positioned air outlets delivering 20% faster cooling and heating response for uniform cabin temperature and superior riding comfort.

All control levers and switches are within easy reach with ergonomic layout, enabling smooth transition between operation modes, lowering operator fatigue and supporting relaxed, efficient work.

Dual-slide adjustable seat supports fore-and-aft positioning to fit operators of different physiques, optimizing human-machine interaction and improving both productivity and long-hour comfort.

Safety

The brake underpressure alarm system monitors brake pressure in real time and triggers instant alerts for abnormal pressure, preventing brake failure and securing driving safety during all operations.

Full-spectrum lighting system integrated with high-brightness LED lamp groups provides high visibility illumination to light up the entire working zone, guaranteeing safe operation day and night under harsh site conditions.

Dozer blade anti-sinking design equipped with hydraulic lock prevents unintended blade drop during travel and operation, eliminating potential safety hazards and stabilizing machine performance throughout work cycles.

High-definition rearview camera system displays rear-site conditions in real time to detect surrounding obstacles accurately, completely eliminating rear blind zones and drastically boosting operational safety.

Easy Maintenance & Intelligence

4G-powered remote intelligent management system (iLink) conducts automatic intelligent inspection, synchronizing real-time machine status and fault early warning data. It enables full equipment oversight without on-site attendance for streamlined fleet management.

Service components are centrally arranged; cartridge filters for engine oil and diesel oil adopt pull-out design, supporting one-stop maintenance without disassembling complicated assemblies to save servicing time and reduce maintenance difficulty.

Side-swing service doors and flip-up engine hood open to a wide angle, allowing easy access to core assemblies without bending or crawling under the machine, greatly simplifying routine inspection and repair work.

Low-mounted air conditioning layout delivers convenient filter cleaning and replacement without special tools, making daily upkeep simple, time-saving and labor-efficient to lower total machine operation costs.
