Today, I will introduce you to the world's first 240-horsepower high-drive electronically controlled hydrostatic transmission type bulldozer.
Product advantages:
'Blue' electronic control engine with three-stage emission standard
World famous brand hydrostatic load feedback transmission system
High-end electronic control system to achieve all-round security, intelligent, friendly human-machine exchange function
High drive walking technology
Proportional pilot controlled work unit hydraulic system
Comfortable operation and environment
Powerful
It adopts the electric control engine conforming to the national phase III, and is equipped with a three-stage air intake filtration system. It has stronger dynamic performance, cleaner discharge and more fuel saving.
Driving
SD7K's electro-hydraulic control method completely eliminates the cumbersome mechanical control, and realizes the simple and fine operation that the bulldozer can't realize in the past, ensuring that the SD7K can easily cope with various complicated working environments.
The proportional walking handle is an integrated handle that integrates direction, speed and left and right steering, and integrates the three joysticks in the original mechanical control into one. The handle rotates the setting direction forward and backward; the left and right rotation adjusts the left and right steering, and the steering has the standard mode. And slow mode, standard steering, small radius steering, differential steering. Thumb wheel set speed. The handle design is ergonomic, comfortable, moderately maneuverable, combined with electronic hand, foot throttle, completely liberated the operator , making work a pleasure. Proportional pilot-controlled work unit hydraulic system. Small maneuvering force, soft hand feeling, sensitive movement, obvious proportional characteristics, high fretting performance, greatly reducing the labor intensity of the driver and improving the bulldozer's It is efficient, safe and reliable. It can be locked when the working device is not used, avoiding the danger of misoperation.
The electronic control system is equipped with a high-performance combination meter display panel to realize all-round safe, intelligent and friendly human-computer interaction function. The combined instrument integrates 6 pointer-type meters, an LCD screen and warning icons, and provides 25 alarms. Or status indication. Using feedback pressure, temperature, oil level, current, voltage and other signals can achieve diagnostic faults, alarms, and even lock the car, so that the whole machine works safely and efficiently.
Temperature controlled proportional heat dissipation system
Constantly reducing the noise of the bulldozer during work, reducing the impact on the residents and drivers around the site is our unremitting pursuit. To this end, we have designed a hydraulic fan that automatically adjusts the speed according to the needs, to meet the heat dissipation requirements at the lowest possible speed, thus Reduce noise and improve fuel efficiency. The hydraulic fan has a reversal function to remove debris and dust from the radiator.
Transfer case and three-stage planetary reduction final drive
The SD7K equipped with the transfer case, the planetary reduction final drive is the core power transmission component for the hydrostatic transmission. The transfer case distributes the engine torque smoothly to different hydraulic pumps, and the original integrated three-stage planetary deceleration The drive converts the power of the hydraulic motor into the movement of the track.
As the core components, all the shells and gears have undergone rigorous mechanical calculations and working conditions to ensure their durability and smooth operation under different working conditions.
High drive walking technology
The unique high-drive design in the country improves the performance of the SD7K. The final drive system is above the travel frame, separating the drive sprocket from the travel frame, and the track is triangular. The final drive system is protected from the extra impact load caused by the ground undulation. Effectively improve the life of the drive motor, the operator is more comfortable driving experience.
Driving environment
The SD7K cab features a fully covered interior that hides the icy cab interior skeleton, with compartments, coat hooks, cup holders and other user-friendly accessories.
Low noise and low vibration are the advantages of hydrostatic bulldozers. At the same time, SD7K cab uses a large number of sound-proof sponges, double-layer flooring, patented sealing strips and other targeted noise suppression design to make the cab have excellent sound insulation. Mounting and suspension seats allow the operator to work in a more comfortable environment.
As an established enterprise in the development and manufacture of bulldozers in China, Hegang Group Xuangong Company (formerly known as Hebei Xuangong) has deep research and development and manufacturing base. Based on the overall development trend of domestic and international construction machinery industry, competitive situation and its own advantages, it differentiates around the market. Demand, adhere to scientific and technological innovation, adhere to technological progress, and actively promote product upgrade structure adjustment and upgrading. SD series bulldozers are a full range of high-performance bulldozers independently developed by digesting and absorbing the most advanced technologies and development trends in the world.
