The invention provides a lifting device and a lifting system. The lifting device comprises a traction wheel, a first winding wheel, a second winding wheel, a third winding wheel, a fourth winding wheel, a first traction wire and a second traction wire. The first traction wire sequentially winds around the first winding wheel, the traction wheel, the second winding wheel and the third winding wheel from the first traction end of the first traction wire to the second traction end of the first traction wire. The second traction wire sequentially winds around the fourth winding wheel, the first winding wheel, the traction wheel and the second winding wheel from the first connecting end of the second traction wire to the second connecting end of the second traction wire. The lifting system comprises a support, and lifting devices are arranged on the two opposite side faces of the support. Two sets of traction structures are set for the traction wires of the lifting devices, and synchronous lifting of the two sets of traction structures can be achieved under driving of the same traction wheel. The structure is simple, and reliability is high. One drive mechanism is adopted in the lifting system and drives the two sets of traction wheels, accordingly, synchronous movement of the two lifting devices is achieved, the lifting device is suitable for lifting of large carrying tables, and high balance and stability are achieved.
