A. First generation of 10m3 excavator: WK-10, Second generation:WK-10A, First set WK-10 manufactured in 1977
B. Dominant product of 10m3 excavator:WK-10B,10m3 excavator had been sold for about 62 sets
C. Based on WK-10B had been carried out the mode variation design of WP-6 Long Boom Excavator, increase the length of lifting arm to satisfy the process requirement of opencast mine deep extract loading.
WK-10B is the third generation modified WK-10 machine type, and also the present 10m3 excavator dominant product, had won the National Best Quality Product Gold Prize and Science & Technology Advance Prize. This kind of excavator bucket volume are 10m3, 12m3, 14m3, flat type 10m3, flat type 12m3 5 kinds of bucket for user selection, suitable for ten million tons class large opencast extract of construction material, hydro-power, petroleum-chemistry etc. earthwork engineering, suitable in combination with 100-154 t trucks, and also a lowest environment work temperature of -45°
