SDLG Wheeled Excavator EA7155H

Product Description

Outstanding Reliability

Equipped with reinforced working equipment, wear-resistant bucket and high-rigidity lower frame, the machine features superior structural strength to greatly extend service life and adapt to heavy-load operations.

It adopts fixed-shaft electro-hydraulic shift transmission and wet drive axles from world-famous brands including ZF, with proven reliable performance verified by long-term market application.

The world-renowned Kawasaki hydraulic system delivers stable operation, low failure rate and excellent durability to guarantee long-term efficient equipment operation.

Superior Working Efficiency

Lingong advanced power matching technology enables seamless coordination among power, transmission and hydraulic systems with efficient linkage of all modules, comprehensively boosting productivity to handle high-density working scenarios effortlessly.

The fully upgraded negative flow hydraulic system realizes more coordinated and precise compound movements with smooth fine control. It accelerates operation rhythm and shortens hydraulic cycle time to reach a new level of working efficiency.

Combined with large-displacement main pump, large-bore main valve and swing motor assembly, the machine gains stronger lifting force and higher swing torque. Its working efficiency is improved by 10% compared with the previous generation, helping customers break production bottlenecks rapidly.

Energy-saving & Low Operating Cost

It is fitted with FAW Jiefang 6-cylinder low-speed high-torque Stage IV engine without urea aftertreatment system. Featuring rapid response, powerful output and sufficient power margin, it copes with diverse working conditions easily.

The hydraulic system integrates dual-pump confluence and flow regeneration functions to shorten hydraulic cycle time, deliver fast operation and outstanding energy-saving performance.

The electrical system adopts Lingong exclusive EECU and VECU electronic control units with multi-mode power selection to balance energy conservation and high productivity.

Comfortable Operating Environment

The ROPS cab adopts a newly reinforced high-strength frame structure with wide viewing visibility. Its sealing and impact resistance performance is improved by 30% for safer and more comfortable operation.

The 8-inch color LCD instrument integrates rear-view camera function, with all control switches centrally arranged within easy reach to ensure safe and user-friendly operation.

The automatic air conditioner with multi-stage filters and multiple air outlets delivers powerful cooling effect. The vibration-damping operator seat effectively absorbs vibration, raising comfort level by over 40% compared with the prior model.

Comprehensive Safety Protection

The under-pressure alarm system monitors brake pressure in real time and triggers instant alarms under abnormal conditions to prevent brake failure and guarantee safe traveling at all times.

The full-function lighting system is equipped with high-brightness LED lamp groups with superior visibility to illuminate working paths and ensure safe operation day and night under complex environments.

The anti-settlement dozer blade with hydraulic lock prevents blade dropping during operation and traveling to eliminate potential safety hazards and ensure stable working performance. The high-definition rear-view camera displays real-time rear conditions and gives early warning of surrounding obstacles to completely eliminate reversing blind zones and greatly improve operational safety.

Convenient Maintenance Layout

Left and right side hoods as well as engine bonnet can be opened at a large angle to provide ample service space for easy inspection and repair.

EECU and air filter are centrally arranged inside the left door, while engine oil filter and fuel filter are grouped inside the right door to realize fast and convenient daily servicing.
