  • Tenova TAKRAF Compact Bucket Wheel Excavator SRs(H)1050

    Mar 20, 2011 · The bucket wheel excavator achieves a theoretical output of 4800lm3/h. The belt width is 1.8m, the bucket wheel outreach 27m and the bucket wheel is powered by a driving power of 900kW. The block effectiveness of the excavator is approx. 0.8 and therefore approaches the block effectiveness of large bucket wheel excavators.

  • Sustainability | Free Full-Text | Simulation of the Time

    The kinematic drive chain of the bucket wheel and the conveyor belt, which are also vibration generators, were simulated only by the static load produced on the excavator's boom. Thus, it is possible to highlight the time response of the load-bearing structure (the boom) of the bucket wheel to the action of forces resulting from the cutting

  • Periodic Autoregressive Modeling of Vibration Time Series

    Jan 17, 2014 · The gearbox operates in a bucket wheel excavator (heavy duty mining machine) subjected to cyclic load/speed variation due to the digging/excavating process. Due to periodicity of the excavation process, it seems appropriate to assume a periodic autoregressive (PAR) model for the deterministic high energy components.
