The invention provides hoisting equipment and a hoisting method for hoisting an inner courtyard pipeline. The hoisting equipment comprises an overhanging derrick, a hoisting point adjusting hoist, a hoisting fixed pulley and a steel wire rope, wherein the overhanging derrick is arranged at the highest part of the containment of an inner courtyard and partial structure of the overhanging derrick protrudes toward the inner part of the inner courtyard; the hoisting point adjusting hoist is connected to the overhanging derrick; the steel wire rope passes through the hoisting fixed pulley and is connected with a winch; the derrick comprises horizontal longitudinal beams and horizontal cross beams arranged on the top parts of vertical legs, and hoisting cross beams which are connected with the horizontal longitudinal beams and protrude to the inner edge of the containment; ultra-static fixed tilting struts are welded to the bottom surfaces of the horizontal longitudinal beams and the horizontal cross beams, and are connected with the lower half parts of the vertical legs; a hoisting fixed pulley is installed between the hoisting cross beam and the horizontal cross beam; one end, passing through the hoisting fixed pulley, of the steel wire rope is connected with the winch, and the other end of the steel wire rope is connected with a hoisted pipeline; a lifting lug of a hoisted material is provided with pair hoists connected with other lifting lugs. According to the invention, defects of a traditional construction technology are remedied, the pipeline hoisting and positioning accuracies are ensured, and the hoisting safety and efficiency are improved.
