AILISHENG LARGE EXCAVATOR ALS550.9
Strong power
Strong power, high torque, low fuel consumption, and high efficiency.
The new generation Cummins QMS11 engine has a power of 333Kw, strong power, and sufficient power reserves, it can meet the requirements of customers for heavy-duty operations.
Innovative technology - large displacement, high torque,independent cooling system.
Hydraulic system: Japanese original Kawasaki
The classic Kawasaki negative flow control system has stable and efficient performance, with high energy-saving effect for boom and arm regeneration, priority action and other functions, and high comfort for operation;
A large displacement single rotary motor has the advantages of high torque, reliable performance, and more reasonable spatial layout
Hydraulic system: Large displacement electric controlled piston pump, ensuring optimal heat dissipation effect.
The large displacement piston pump, combined with a large displacement motor, can be equipped with a large diameter fan, which has the advantages of large suction air volume and low speed, effectively meeting the heat dissipation function and reducing fan noise
The electronical controlled piston pump can control the pump displacement and fan speed based on the hydraulic oil temperature, which has a significant energy-saving effect.
Independent dual cooling system
Adopting a completely independent dual cooling system, water and oil dispersion are independently controlled without interference, and the fan speed is automatically adjusted according to temperature. Equipped with one click reverse function, the radiator maintenance is convenient and fast. Suitable for high-temperature environments and harsh work conditions.
Configure Desert Prefilter
Configure a desert prefilter to ensure that the machine can operate normally under harsh working conditions with high sandstorms.
High strength structures - heavy-duty reinforced design of structures, with a powerful appearance.
Five major structures(Boom & arm) are designed with heavy-duty reinforcement, and through finite element analysis, their load-bearing capacity is greatly improved compared to the same tonnage models in the industry.
The key parts of five major structures(upper frame & bucket) are made of high-strength plates and wear-resistant materials, which improve reliability and service life.
The track of five major structures(Track frame) adopts a double tooth metal pin type track, with a simple structure, convenient maintenance and replacement, and strong grip.
High strength structures - heavy-duty reinforced design of structures, with a powerful appearance.
The overall design of the machine is unique and atmospheric, with a powerful appearance. The side doors, hood, and other parts are all reinforced in design.
Equipped with a standard anti overturning and anti falling object cab, it effectively avoids the risk of being hit by flying rocks in harsh working conditions.
The cab features a novel design, wide field of view, and user-friendly design, equipped with a rear,view camera for a wider field of view.
Convenient and fast maintenance
Engine maintenance and upkeep are concentrated in the pump compartment, making it easy and safe to,carry out maintenance and upkeep.
Through the selection of accessories, to cope with different working conditions, in order to achieve multi-function of one machine
To improve work efficiency, buckets with different capacities can be configured according to the principle of"one mine, one bucket" to meet various working conditions.
The optional bucket capacity of this model is 2. 9-3. 6m. ³ among rock, heavy loads, light loads, earth buckets, etc.
Optional 60-ton grade 195 / 210 breaking hammer to meet heavy-duty working conditions.
