TEAM TECHNOLOGY

  • “TEAM" technology is a Chenggong exclusive management solution which integrates Transmission, Engine and Attachment to improve the working efficiency and to reduce energy consumption.

         It is the evidence showing Chenggong constant effortsfor technology exploration and satisfaction of reducing final customers cost. Chenggong technology upgrading, like its social responsibility, never                 stops.

  • Chenggong has introduced TEAM technology into a new generation of construction machinery and equipment.

         By a new hydraulic and hydrodynamic transmission energysaving technology with 100% intellectual property right and the application of Dynamic Simulated Structure Analysis Program in wheel loader               design, energy utilization efficiency and fuel economy are improved.

         Fuel consumption down 10%,but operating efficiency up 12%.

 

MACHINE FEATURES

  • ATTACHMENT

         1. Forged hydraulic cylinder head, not easy to break and the piston rod is quenched by medium frequency, with higher hardness,strength and longer life.


         2. The pin shaft uses alloy steel material and the yield strength is increased by 160%.It is matched with the different dust-proof structure to prevent the sediment from entering the pin hole. The oil hole                     cylinder sleeve ensures that the pin shaft is fully lubricated.


         3. The bucket,equipped with wear-resistant plate, is made of special steel bucket teeth are made of wear-resistant alloy steel material + forging excavator bucket teeth technology.The wear resistance is                     1.5~2 times higher than before.


         4. Unique Chenggong design of bucket shape makes the transportation position angle up to 51°,Each bucket actual loading is more than before, and the hopper does not spill during the walking. Shovel                   cutting operations are more comfortable,greatly increasing the full bucket rate and ensuring high output ratios for customers.
         
5. The electronic leveling device and the lifting cylinder limit system is useful to improve the control accuracy and improve the work efficiency.
         6. Different buckets and attachments are designed for different materials to ensure maximum machine efficiency.

  • HYDRAULIC SYSTEM

         1. With Chenggong TEAM high pressure hydraulic system,and the Max bucket breakout force 220 kN.

         2.Coaxial flow amplifica-tion steering system, flexible steering and high efficiency.

         3. International level high-pressure pipeline equipment to reduce manufacturing defects to as low as possible, like zero.

         4. Large-diameter hydraulic pipe lines reduce energy consumption during hydraulic power transmission and reduce operating costs.

         5. Advanced steel pipe welding technology ensures smooth weld seam, no slag pollution, and low flow resistance inside of pipes.

  • ELECTRIC SYSTEM

        1. Different sensors, combined with the instrument,could timely grasp wheel loader working information, which makes the operation is more safe and efficient.

        2. Three sets of working headlights guarantee high brightness,strong penetrating power,wide illumination range,and even high efficiency at night.

        3. The wire harness is manufactured by
world-class processing equipment and components. It is sealed well and corrosion-resistant for stable power supply.

        4. Advanced cold starting battery keeps long time energy storage, and ensure stable power supply in low-temperature.

  • TRANSMISSION SYSTEM

        1. The hydraulic torque converter with the TEAM technology can achieve a hydraulic conversion rate more than 86%.A fixed shaft electro-hydraulic shifting gearbox with 4 forward and 3 backward, ensures                fast shifting and high-efficiency operation.

        2. 
Chenggong 70 Wet axle with 100% intellectual
property is an important step of the drive axle technology.It has been widely praised by customers both at home and abroad since its beginning. To face                    slippery ground,LSD device is also equipped.

        3. The new drive shaft adopts double universal joint intermediate support making torque transmission more stable. The 7C flange effectively prevents the bolt from being damaged so that the connection is              reliable.

        4. The wheel oil seal is a new labyrinth oil seal model and a new venting cap structure modal, which has better sealing and antisand effect, a nd is effective in extreme conditions.

        5. Fully hydraulic automatic axle temperature control function by air cooling ensures that wheel loader remains highly efficient under high load conditions.

 

STRUCTURE FOR DRIVER TRUST

1. It adopts the unique tower box frame of Chenggong, equipped with large-distance hinged tapered bearings,long wheelbase arrangement, reasonable structure,perfect for carrying super load.

2. The counter-weight assembly has an attractive and useful outlook with backslope 27°, providing good mobility when working condition is steep slope.

3. Streamlined steel mud, solid and reliable,can effectively block the sediment and reduce its pollution and damage to the whole machine.

4. Superior rear axle oscillating ability helps to maintain the loader in four rounds of contact with the ground in rugged conditions, providing excellent traction.

 

POWER FOR RELIABLE

1. WEICHAI WP12G series engine models with China lll emission level, keep low speed, high torque and strong power.


   TEAM technology and above engine models ensure stable power output and longer service life.

2. The new shock-absorbing radiator makes the its body flexible and avoids the cracks in the welding position of water channel. Compared with the previous generation,its durability is greatly improved.

3. The Donaldson air filtration system could effectively work in the dusty working conditions, ensuring the cleanliness of the engine systems,preventing the early wear of the engine,and improving the fuel burning rate which is good for environmental protection and less fuel cost.

4. Cooling system--Flat single-layer structure with
 
windward design. The new designed layout of the radiator improves the heat dissipation ability for both radiator and the torque converter,ensuring that the oil temperature and water temperature are stable in the optimal efficiency state.

 

TOUGH WORK IN 360° ENVIRONMENT

1. 360°cab is spacious and comfortable with an open view. Such cabin design has a number of patents. Its convex wide-angle rear-view mirror greatly expands the driver's rear view range.

2. Two air outlets to remove the frost of front window and ensure the driver's sight is clear.

3. Adjusting window glass on the left enhances air flow and keep the indoor air fresh.
