Counterweight is a hoisting vessel designed to balance adjacent vessels (cages, skips), unbalanced and multi-rope hoisting systems used in vertical shafts at coal-mining and mining enterprises.

      Counterweights are distinguished by the following design features/parameters:

- shape of the counterweight steel structure frame;

- hoisting type (unbalanced, multi-rope);

- location of the maintenance platform (on the upper beam of the frame, directly in the counterweight frame);

- guiding unit type (guide slides for box-type, rail and rope guides; spring-loaded roller guides for box-type guides).

SMZ PJSC manufactures a wide range of counterweights with any required combination of the above design parameters.

SMZ is also able to design and manufacture customized counterweights.
