Practical Case: Deep Mine Well Hoisting Project
A gold mine project requires hoisting ore in a vertical shaft with a diameter of 3 meters, where traditional winches cannot be installed due to space constraints. The Rongjing team customized a vertical reciprocating winch solution:
STEP 1: Utilize a compact body design, reducing height to 2.8 meters, suitable for wellhead space.
STEP 2: Configure a double-layer steel wire rope wrapping system, lifting height up to 800 meters.
STEP 3: Integrated fall protection device, certified by MT/T 1097 Mining Equipment Standards.
Post-implementation, the equipment's operational stability reached 99.2% and annual maintenance costs decreased by 40%.
