The ZL30-II loader adopts the YTO LR6108 G6F1 diesel engine, which is produced on the basis of technologies from the British Ricardo Consulting Engineers. and is featured with a big power reserve, strong output power, low specific fuel consumption, environmental protection-oriented. The loader adopts the single-stage 3-element hydraulic torque converter, the fixed-spindle 4F+2R power gearshift transmission box, and both are featured with their reliable performance. The loader adopts the full hydraulic steering device, which is flexible and easy to operate, small in its turning radius and stable in its performance. The front and rear frames adopt the box-type structure, which is strong in its strength and good in its rigidity. The four-wheel double-tube caliper-disc type brakes and the air reservoirs positioned on both sides guarantee the desirable brake performance in traveling and operations, making the loader safe and reliable. The loader adopts the Z-shaped link mechanism and has strong lifting power, thus the shoveling and digging work is high in efficiency. The vehicle has a new-type steel-structured driver's cab, which is good at its sealing and vibration absorption and can provide a broad field of view. Besides, the loader adopts the advanced traversing combination instrument panel and the anti-misstart electronic switch lock, bringing the human-centered designing philosophy into full play.
