The invention discloses a lifting device with elastic tension, belongs to the technical field of cranes, and relates to a lifting device. The lifting device comprises telescopic guide rails, a guide rail fixing platform, a lifting system, a tensioning mechanism and a clamp; the two telescopic guide rails are oppositely fixed to the guide rail fixing platform; the clamp is fixed to the bottoms of the two telescopic guide rails; the lifting system comprises a motor, a winding drum and steel wire ropes; the motor is fixed to a motor supporting plate; the winding drum is connected to the motor; the two steel wire ropes wind the winding drum in opposite directions; the tensioning mechanism comprises an elastic rod and two pulleys; the steel wire rope which winds the winding drum in counterclockwise direction is directly connected with the guide rail connecting plate; and the steel wire rope which winds the winding drum in clockwise direction penetrates through the two pulleys in sequence toconnect the guide rail connecting plate in opposite direction. The lifting device with elastic tension can effectively avoid the problem of loosening of the steel wire ropes, and can be widely popularized and applied to crane lightweight designs.
