TECHNIQUE OF SELECTION OF ONE-BUCKET EXCAVATORS FOR CLEANING OF CHANNELS OF DEPOSITS

Abstract

Two main technological schemes to cleaning of channels of deposits are considered: cross development when for one pass the excavator completely develops channel section, and bilateral cross development on which the design section of the channel is carried out for two working passes. The dependences considering performance data of the excavator and parameters of the channel are developed for selection of excavators for each technological scheme. The developed dependences significantly differ from existing since consider design features of each brand of the excavator. For the main brands the one-backed of excavators with the equipment the return shovel, reclamation systems available in the enterprises, dependence of radius of digging on depth of the channel is presented graphically. The technique of selection of excavators which is considered on examples is offered. At possibility of performance of work by several brands of excavators the most economic option with use of schedules of a factor cost gets out.
