“…The hybrid model of the overhead crane is based both on the numerical simulations of drive mechanisms and on the measurement of the values of energy consumed by the drives control system. [13] Numerical model of the lifting mechanism fed by inverter is widely discussed in the paper [14]. Figure 3.1 shows model of the hoist driven by an asynchronous motor fed by an inverter, developed basing on the model described in [13].…”

EnErgy consumption and EnErgy EfficiEncy improvEmEnt of ovErhEad cranE's mEchanisms EnErgochłonność i poprawa EfEktywności EnErgEtycznEj mEchanizmów suwnicy pomostowEjThe article presents the numerical investigation of the overhead crane's energy consumption. The analysis is based on the hybrid model of the crane consisting of numerical model of drive mechanisms as bridge, trolley, hoist and also experimentally measured power consumption of each control unit. The numerical model was verified experimentally on the real crane. The investigation focuses on analyzing the energy consumption of the overhead crane in relation both to the travelled distance and also for the lifting and lowering heights of a suspended payload. Particular attention was paid on the cases straightly related to the hoist, as a main factor of improvements in the energetic efficiency of the overhead crane. Energy consumption was investigated for a variety of magnitudes of transported mass.

“…In [3], the authors made a complete mechanical description of a bucket conveyor. The authors in [4] developed a method of the influence of a lifting height and weight of the lifted load on the drive overload and duty cycle power consumption. In [5], they presented a model of a crane that enabled the identification of dynamic factors caused by lifting the load off the ground.…”

Study of Energy Consumption of a Bucket Conveyor in a Jig Concentrator Plant in a Hard Coal Mine

The subject of the discussion is oriented toward limiting the energy consumption of the bucket conveyor used in jig concentrator plants by controlling its speed. A method of predictive control of the bucket conveyor speed is presented. It allows for reducing the energy consumption due to appropriate selection of bucket movement speed to ensure the nominal filling of buckets along the entire length of the conveyor. This approach enables limiting the idling speed of the conveyor, extend its life, and also reduce the electricity consumption of the entire system. Experimental studies, carried out at the “Sośnica” Coal Mine working facility, confirmed that the use of a predictive algorithm for controlling the bucket conveyor speed and adapting the bucket speed to the current load decreased in energy consumption n by 9.6%, with 80% of the filling conveyor.

“…Operational mechanisms and high operating speeds cause unbalance of the load from the equilibrium position. Information about the dynamics of the load while transportation, play an important role in the context of its positioning and control of mechanisms [1,2]. At the same time, the limitation of the swing has a decisive effect on the manoeuvrability, thus minimizing the effect of cargo collision with fixed obstacles [3][4][5].…”

The paper presents the results of numerical investigations of the overhead travelling cranes load motion. The model studies assumes that the load is suspended on the inextensible rope. Conversely, its motion is triggered by an external moment. In addition, energy losses in the construction node connecting the rope to the drum are included. At the same time these losses were mapped through a linear viscous damper. The main objective was to evaluate the impact of individual mathematical model parameters on the dynamics of the transported load. The results were compared between two models: with/without crane structure vibrations included. The results were illustrated by multi-colored maps of the largest Lyapunov exponent, bifurcation diagrams, and Poincare cross-sections.
