Therefore, the installation position of the lifting lug 2121 on the lifting lug support 2124 can be adjusted according to the requirement of the installation angle of the generator 1, so as to meet the requirement of the turning angle of the lifting appliance 2 and the generator 1. In one embodiment, the first angle may be 90 °, and the second angle may be 96 °, but is not limited thereto.

5. The generator upender spreader of claim 3, wherein the lifting lug support includes a plurality of attachment locations pivotally attached to the lifting lugs, the plurality of attachment locations including a load-lifting location and an empty-lifting location, the lifting lugs being pivotally attached to the load-lifting location when the generator is moved to a target position by the generator upender spreader, and the lifting lugs being pivotally attached to the empty-lifting location when the target position is removed from the generator upender after the generator is removed from the generator upender.
6. The generator upender spreader of claim 5, wherein the lifting lug support includes a chute, the load and empty lifting positions both communicating with the chute, the lifting lug moving along the chute from the load lifting position to the empty lifting position.
7. The generator turning sling according to claim 5, wherein the load hoisting position is arranged such that, after the generator turning sling carrying the generator is hoisted, the load hoisting position is located on the same vertical plane as the center of gravity of the combined body of the generator turning sling and the generator; and/or
The no-load hoisting position is set to be on the same vertical plane with the gravity center of the generator turning hanger after the generator turning hanger without the generator is hoisted.
8. The generator upender spreader of claim 5, wherein the load lifting positions include at least a first load lifting position and a second load lifting position, the lifting eyes being selectively pivotally connected to the first load lifting position or the second load lifting position, the generator upender spreader and generator being tiltable to a first angle after being lifted in the first load lifting position, the generator upender spreader and generator being tiltable to a second angle after being lifted in the second load lifting position.
9. The generator upender spreader of claim 8, wherein the empty lifting positions include at least a first empty lifting position and a second empty lifting position, the lifting lug being selectively rotatably connected to the first empty lifting position or the second empty lifting position, the first empty lifting position being configured such that the generator upender spreader flipped to the first angle can be detached from a generator from a target position after being lifted by the first empty lifting position, and the second empty lifting position being configured such that the generator upender spreader flipped to the second angle can be detached from a generator from a target position after being lifted by the second empty lifting position.
10. The generator turning sling according to any one of claims 1 to 9 further comprising a backing plate, said backing plate being laid underneath said generator turning sling, said turning end being in contact with said backing plate during turning of said generator turning sling.
