The invention relates to a hoisting method of a slurry pump crankshaft. The slurry pump crankshaft comprises a crankshaft, and crankshaft connecting rods arranged on the crankshaft; the slurry pump crankshaft is arranged in a slurry pump housing; and the crankshaft connecting rods are arranged in a cross-shaped head chamber of the slurry pump housing. The hoisting method comprises following steps: 1, a special hoisting device used for slurry pump crankshaft assembling is designed and produced; 2, a crankshaft hoisting rigging is used for connecting a hoisting pipe hoisting apparatus to realize whole hoisting of the crankshaft; 3, a crankshaft connecting rod hoisting rigging is used for connecting the crankshaft connecting rods with the hoisting pipe so as to keep level conditions of the crankshaft connecting rods; and 4, the crankshaft is hoisted into the slurry pump housing, the three crankshaft connecting rods are completely inserted into the cross-shaped head chamber, hoisting is completed, and the hoisting riggings are disassembled. The hoisting device comprises the hoisting pipe, a main hoisting rigging, the crankshaft hoisting rigging, and the crankshaft connecting rod hoisting rigging. The hoisting method and the hoisting device are capable of realizing stable hoisting and assembling of the slurry pump crankshaft, are safe, and are capable of saving labour and time.
