Method for transporting heavy equipment under large-gradient condition under mine

The invention discloess a method for transporting heavy equipment under the condition of a large slope under a mine. The method comprises the steps that two 20 t movable pulleys and one 20 t fixed pulley are used in cooperation with two JSDB-19 type prop pulling winches, a phi 26 mm steel wire rope is hung for 1000 m lifting, the two JSDB-19 type prop pulling winches are installed in a winch chamber, and the two JSDB-19 type prop pulling winches are installed in the winch chamber; wherein the fixed pulley is fixed between the two winches, the two movable pulleys are connected with the withdrawing forklift, and the phi 26mm steel wire rope penetrates through the two 20t movable pulleys and the 20t fixed pulley to be connected with the two JSDB-19 winches to form a closed-loop movable steelwire rope. Accidents such as rope breakage and car running caused by insufficient safety coefficient of breaking force of a winch steel wire rope are avoided, the safety coefficient is improved, a thought with great value sig
