The winch is boring

Boring winches are the main executive mechanisms for rise and descent of a boring column, its deduction on weight or slow lowering when giving a chisel on a face in the course of drilling, descent of upsetting columns and other works.

On a design of the winch are subdivided into two groups: two - or three-valnye.

Winches of the first group consist of a welded frame on which are mounted on rolling bearings a lifting shaft with a drum for a navivka of a talevy rope, intermediate and transmission shaft. All shaft are kinematic connected among themselves by chain transfers which transfer them torques and are used for regulation of frequency of rotation of shaft.

We expect a vysha the application!
