1. An elevator traction machine installation apparatus, comprising:
a lifting mechanism having a base portion and a load-bearing portion adapted to place an elevator traction machine, wherein the base portion and the load-bearing portion are connected and configured to be capable of rising and lowering relative to each other in a longitudinal direction of an elevator hoistway; and
a support mechanism configured to be detachably connected with the lifting mechanism and a base for installation of a machine-room-less elevator traction machine in the elevator hoistway to support the lifting mechanism and the elevator traction machine, and having at least two positions at which the base portion is secured, wherein a first position is lower than a second position in the longitudinal direction, and the load-bearing portion is lifted relative to the base portion after the base portion is secured at the first position, and continues to be lifted relative to the base portion after the base portion is adjusted and secured at the second position, until the load-bearing portion is substantially flush with an elevator traction machine installation position on the base in the longitudinal direction, to allow the elevator traction machine to be moved from the load-bearing portion to the elevator traction machine installation position;
wherein the support mechanism comprises:
at least two support parts each comprising a connecting bracket, a diagonal brace member and a first member, wherein the connecting bracket is secured to the base, the first member is connected to the connecting bracket via the diagonal brace member and has a first connecting portion, the first member is secured to a guide rail for installation of the machine-room-less elevator traction machine through the first connecting portion, and the guide rail is connected to the base and extends in the longitudinal direction;
at least two second members arranged below the base and in parallel to each other, and spaced in a transverse direction of the elevator hoistway, wherein the second member is connected to the first member and has at least two second connecting portions, and the base portion is secured at the first position through the second connecting portions; and
at least two third members arranged below the base for connecting the lifting mechanism and the second members, wherein the third member has at least two third connecting portions, the third member and the second member are connected through the third connecting portion and the second connecting portion, and the base portion is secured at the second position through the third connecting portions.
