The paper proposes a method of smooth hoisting for large-scale equipment in the limited space,named SHLL,to solve the shortcoming of the traditional hoisted method.The composition and basic principles of SHLL were described.The force bearing formula and analysis program were given by analyzing the deformation and force states of steel wires at the hoisted process,and proved by an application instance of SHLL.The results indicate that the composition of SHLL is brief,easy to control and safe.The SHLL ensures the equipment stable under lifting,translating,and descending.The movements and force states can be calculated exactly by the force bearing formula.The force bearing analysis program can rapidly analyze the hoisted process and force states and make data visualization.
