Excavator model name Bucket volume at 1.8 t rock density Possible bucket capacity range WK - 12 12 m3 8-16 m3 WK - 20 20 m3 16-34 m3 WK - 35 35 m3 25-54 m3 WK - 55 55 m3 36-76 m3 WK - 75 75 m3 75 m3 Excavators of the WK series are crawler mining excavators of the front shovel type with a rope mechanism for lifting the bucket and an electric AC drive, designed for the excavation and loading of minerals and overburden into vehicles in open pit mines. When developing the structures and mechanisms of the WK series mining excavators, the most modern design technologies were used, including three-dimensional computer modeling. This excavator shows high efficiency, has increased compatibility with a wide range of dump trucks and crushing station, effectively fulfills customer requirements for unloading, and reduces production costs. The electrical part uses a modern control system for AC drives with frequency conversion, with common DC buses. The system has the following advantages: reduction of the level of electrical noise in the power grid; as a result - economical power consumption; self-adjusting software that allows the excavator to adapt to various working conditions; self-diagnostics of the system, displaying the status of equipment and operating faults; metering and saving electricity, etc. Technical features: The rack-and-pinion thrust mechanism provides high-quality penetration and high digging efficiency; Independent drives of the travel mechanism with planetary gearboxes; Increasing the resource of gears by improving the quality of mechanical and heat treatment of tooth surfaces; The drives are located high above the ground, which reduces the likelihood of damage. Application of pneumatic disc brakes of the main mechanisms of the excavator; Frequency control system for the drives of the main mechanisms of the excavator. 2017 © LLC "AVIK EQUIPMENT AND ENGINEERING" design & marketing
