Estimation of the crane moving resistance during it’s running into the end stops

Abstract

Providing safety of hoist cranes operation requires the estimation of the horizontal force
during crane’s running into the end stops that do impossible derailment of crane. It’s necessary for
calculation of the buffers that shows down the kinematic energy of crane and constructions of end
stops. Estimation of horizontal force of crane’s running will more exactly if during calculation it
will allow for crane moving resistance.
For determination of the crane moving resistance is necessary to know crane dimensiontype, working conditions and kinematic parameters of crane. Working conditions are need for
estimation of coefficient of kinetic friction in slide bearings of wheels and coefficient of rolling
friction of wheel on rail. These coefficients to a greater extent from dirty level of gantry rail, wheels
diameter and rails dimension-type.
Specified value of crane moving resistance allows to estimate not only the horizontal force
during crane’s running into the end stops but necessary power of motors and decrease cost of
movement mechanism, established power and electrical energy consumption.
