Cab Design Technology
The newly designed cab provides low-noise operation and enhanced visibility, creating a comfortable working environment for the operator
Ergonomically designed joystick The new joystick with 4 switches allows for precise control of the machine
Spacious cab with excellent visibility
The ergonomically designed wide cab has low noise and excellent visibility
Panoramic front window, large rear window and side windows provide visual visibility in all directions
Reinforced structure
The thickness of the cab's cylindrical structure has been improved to ensure optimal safety
Improved performance and safety features
Conquer the limit
Track guard and adjuster
Durable track guard protects the track chain from derailing. Standard grease tensioner and vibration absorbing spring make track adjustment easy
Cummins B5.9-C (6BTAA) engine
The six-cylinder, 4-stroke, turbocharged and intercooled engine ensures strong power, reliability, economy and low pollution.
Simple design
The Cummins B5.9-C (6BTAA) engine is designed with 40% fewer parts than traditional models. This means that it is less likely to fail when you need it to work. At the same time, it also means less spare parts inventory. No special tools are required for maintenance, making repairs simple. The weight of the machine is reduced without sacrificing strength.
High strength and good stability
Lower frame
The reinforced box-type structure frame is welded entirely from low-stress, high-strength steel plates.
It is equipped with highly reliable sprocket wheels, supporting wheels and track guards. The track shoes made of high-strength steel can withstand the external impact of the machine walking on rough ground and working in wetlands.
The LC chassis is composed of heavy-duty excavator components.
The X-type middle frame is welded as a whole to ensure maximum strength and reliability.
① Reinforced bucket
The sealed, adjustable bucket connecting rod ensures low wear of the pin and bushing to ensure quiet operation. This design improves the reliability and anti-wear characteristics of the connecting rod. Add reinforcement steel plate to the bucket cutting part.
② Rotating disc engine speed switch
③ Power boost control system
Newly designed hydraulic system
Advanced CAPO system
The advanced CAPO (Computer Aided Power Optimization) system makes the engine and main pump perform at their best. Different power selection modes are designed according to different workloads, which can achieve the best performance under the premise of reducing fuel consumption. The system also has functions such as automatic idling and power increase. The monitor displays the engine speed, coolant temperature and hydraulic oil temperature. The system has a self-diagnosis function, which displays the error code on the monitor.
Automatic deceleration system
When the pilot control valve is in the middle position for more than 4 seconds, the CPU controller sends a command to the acceleration actuator to reduce the engine speed to 1000rpm to reduce fuel consumption and noise radiation.
Boom and arm holding system
The holding valve in the main control valve can prevent the boom and arm from sinking when it is placed in the middle position for a long time.
Boom and arm flow regeneration system
The flow regeneration valve can make the operation smooth and respond quickly without causing cylinder cavitation.
Main pump flow control system
When in the middle position, the main pump flow is reduced to the minimum to reduce power loss. During operation, the actuator is provided with maximum pump flow to increase speed. The pump flow is automatically adjusted by the movement of the joystick, and the cylinder speed is proportionally controlled at the same time.
hyundai 220 excavator Touch idle system
Press the touch idle switch, the CPU controller controls the adjustment motor to reduce the engine speed to 850rpm, and press the switch again to restore the engine speed to the original speed.
Reliability and maintainability
Lubrication points
All lubrication points are arranged in a centralized manner, making it easy to add lubricants
Easy to maintain engine components
The cooling and preheating system is designed with the best matching, so that the machine can be put into use immediately in different environments and ensure a longer life of the engine and hydraulic components. Easy access makes maintenance operations simple.
