OJSC SILVINIT

The purpose of development is equipping of the vertical shaft No. 5, SKRU-2, OJSC “Silvinit”, Solikamsk, Perm region, with up-to-date skip and cage hoist machines such as 2C-5x2.5-TD and CR-4x3/0.9-TD, gearless fulfillment, mechanical part of which includes the multi-element disc brakes of normally-closed type. The 2C-5x2.5-TD hoist machine has a DC slow-speed main motor of normal fulfillment, and the CR-4x3/0.9-TD hoist machine has a DC slow-speed main motor of console fulfillment.

The electric part of the hoist machines is equipped with modern systems of thyristor electric drive, microprocessor systems of control, protection, diagnostics and operation with advanced Human-Machine Interface. The shaft system of signaling, communication and hoist control is of explosion-proof fulfillment and bases on microprocessor controllers with application of special shaft communication cables.

This development has resulted in the high level of hoisting safety due to multi-element structure and high-speed action of the disc brakes, as well as in the high level of automation and self-descriptiveness of control systems due to application of microprocessor techniques.
