The invention discloses a multifunctional safety rope both-way crane. The multifunctional safety rope both-way crane comprises a motor (17), a speed changing device, a hoisting mechanism, a hook (1), safety ropes (9) and lifting hooks (24). The hoisting mechanism comprises an end cover (8), a drive wheel (6), a guide wheel (4) and a pressing wheel (7). The drive wheel (6) is fixed to an output shaft (5) of the speed changing device and provided with V-shaped grooves (23). A plurality of cylinder pins (21) circumferentially distributed are embedded in the V-shaped grooves (23). The V-shaped grooves (23) are halved through the cylinder pins (21), the outer sides of the grooves are matched with the safety ropes (9), and heat dissipation ventilation holes (22) are formed in ventilation cavities in the inner sides of the grooves. The safety ropes (9) surround the V-shaped grooves (23), and a plurality of guiding wheels (4) and a plurality of pressing wheels (7) all of which are used for tightly pressing the safety ropes (9) are arranged between the end cover (8) and the speed changing device. The lifting hooks (24) are fixed to one ends or two ends of the safety ropes (9). After the structure is adopted, the aim of hoisting heavy objects at the high position is solved. The multifunctional safety rope both-way crane has the beneficial effects of being simple in structure, safe in usage, high in hoisting efficiency, convenient to dismount and mount, firm, durable and the like.
