Safety gears (parachutes) for cages with gripping for two brake ropes are designed to catch and smoothly stop a mine cage in case of a hoist rope or suspension gear breakage. They are used for unbalanced hoisting in vertical shafts with a max. depth of 900 m (including gas and dust explosion-hazardous mines) at cage travelling speeds up to 12 m/s.

      PTKA safety gears (parachutes) comply with the requirements of GOST 15850-84, climatic version N (for moderate climate), placement category 5 for retarder and 2 for dampeners and sleeves according to GOST 15150-69.
