W2425LC-8 crawler hydraulic excavator has the largest output net power (320hp) among similar products.
It adopts the most advanced positive flow control method (higher technology level, more energy-saving, higher work efficiency and more comfortable operation, compared to traditional negative flow control). The operation interface applies multiple proprietary intellectual property rights and is more humanized. The overall control system is centralized in the central control display, which can realize high pressure and high precision injection of engine control, and realize multiple control on the control valve, oil pressure and flow.
W2425LC-8 is mounted with a quick return valve, which improves the arm and bucket dump speed and improves work efficiency. Under the supercharging mode, the digging force can be increased by 8%; Multiple work modes are available for users to choose according to actual work conditions.
It is specially designed for mining operations, equipped with reinforced rock bucket, and all the wear parts like bucket teeth all use products of famous brands, which effectively ensures the service life of bucket teeth. Double guards are mounted at the outer edge of the bucket which extends bucket life.
While ensuring the reliability and universality of the electric system, it uses special connector and effectively avoids loose or poor contact under harsh work conditions; meanwhile it adopts waterproof design which effectively avoids dusts and water entering the connector. The electric system is mounted with main switch which can cut of ¡ï Imported Perkins engine has big power, low fuel consumption, low noise and high performance.
¡ï Full hydraulic pilot control system provides smooth operation and machine movement.
¡ï With innovative crank arm design, it can work in cramped site.
¡ï Smart design highlights the flexible characteristic.
W218 crawler hydraulic excavator is equipped with originally imported Perkins engine, which has net power 14.7kW and meets Euro III North America Tier III emission standards. The global service network of Perkins engine can meet global customers' needs for after-sales maintenance and repair.
Key components of the hydraulic system adopt first-class products in the world; Equipped with Parker main valve and Japan Nachi variable displacement pump, it is more energy-saving and cost-effective. Featuring high flexibility and reliability, the ergonomically designed handles are comfortable for European and American users. Electrical control unit adopts simplified design, all the operation controls are located on the armrest box side in accordance with ergonomic design, which guarantees comfort.
The cylinders of working device adopt DH18 technical specifications, which are completely interchangeable and fully guarantee the flexibility of after-sales service. The working device deflection can be achieved, more suitable for narrow work conditions.
W218 is specifically designed to meet the operating habits of target customers. Equipped with waterproof control box and ergonomic seats, it greatly reduces operator fatigue even if in successive operations.
Unique sunshade provides great comfort; Exit passageway is added with guiding device, which helps the operators to cultivate good habits and improves safety. World Heavy Industry has proprietary intellectual property rights of the function.
To ensure safety, W218 crawler excavator is mounted with rotary lock mechanism which is designed to prevent unexpected turn of the superstructure during transport and use of the machine. The travel lock mechanism can effectively prevent misoperation and prevent injuries caused by sudden movement of the crawler.
W218 hydraulic system filter uses product of well-known brand, and the after-sales service and maintenance requirements were fully considered in the design phase; common components are used so that it greatly reduces the maintenance costs and indirectly improves the value of the product.
With the "smart" design concept, W218 has a smooth appearance with reasonable clearance, and it is more like a work of art. the whole power of the machine in the shortest time and maximally protects the machine.
W2425LC-8 cab is equipped with FOPS according to user requirement. The front window uses "CCC" certified one-piece explosion-proof glass, and it cannot harm the operator even if it collides with rocks. The originally imported GRAMMER ergonomic air cushion seat features dual sliding rail, weight adaption, and 4DOF adjustment; Thick waist support effectively reduces operator fatigue. Unique 5-poiont independent suspension silicon oil vibration absorber effectively reduces cab vibration.
To ensure operator safety, World Heavy Industry implements stringent safety requirements. W2425LC-8 is equipped with ergonomic safe operation mechanism, which ensures that the working device can only actuate when it is in the unlocked status, which effectively avoids misoperation.
W2425LC-8 adopts centralized design and layout, taking into account serviceablity. The engine filters are mounted at the same side, which makes engine service and maintenance more convenient. Engine hood can be turned over for inspection of related parts. Cooling system adopts parallel type heat dissipation technology jointly developed by World Heavy Industry and AKG, featuring compact space, improved cooling effect and more convenient cleaning and replacement with extra filtration mesh.
