Final results : Mixer over head crane 50 / 10 ton span 22 , 25 m - Modifications : Main hoist - reducer - using of materials of less hb which is available in the plant (p . 65 , 72 a , 92 a , 96) - no changes in the centre distances of the reducer - same roller bearings - all parameters of the gears are changed (m , dp , z) - the same speed ratio - Drum : drum bearing modifications by using antifriction bearings - carriage : according to the calculation end switch will be less propability of using brake due to adhesion - Auxiliary hoist : Redueer : using materials of less hb which is available in the plant (p 36 , 40 , 56) - All parameters and shafts are the same - Carriage : According to the calculation ends witch will be installed (see chapter 3 , 3 - 4 P 52) - less propability of using brake due to adhesion - Travelling mechanism of trolley : Reducer : Using materials of less HB which is available in the plant (P 107 , 111) - All parameters of gears and shafts are the same - Longitudinal motion : According to the calculation end switch will be installed (see chapter 6 , 6 - 4 , P . 102) - Experimental tes : The test show that it is necessary to make a grinding for gears hoisting reducers to avoid the vibration and the dynamic loads in the main shaft of hoisting Mechanism (P . 152) - Safety engineering : All safety rules for overhesd crane are taken according to the norms (see chapter 9 , P . 136) .
