Konstruktsiyalebedki has the following advantages:
• the control of the electric drive allows to carry out a full stop of freight during its descent and deduction of freight in a motionless state;
• as reserve brake system the disk brake, more compact and effective, than a traditional tape brake which at spusko-podyemny operations, after a freight stop the electric motor of the main drive, is used as the fixing brake is applied;
• the electric motor torque transmission on a lifting shaft of the boring winch is carried out by means of gear transmission. At the same time in kinematics of the winch there are no such unreliable elements as chain transfers and frictional couplings;
• contactless consolidations of shaft allow to exclude oil course outside from the transmission case;
• remote control creates comfortable working conditions for the driller.
