There are two, suspender both ends are respectively arranged at, which is provided with opening lifting lug (31) and lifting hole(eyelet) (32), the opening lifting lug (31) is to open
Mouth rounded corner design, convenient for suspension suspender belt；The lifting hole(eyelet) (32) is closing ring design, and the both ends of the chain sling (5) are separately connected
On lifting hole(eyelet) (32).
Using the hanging method of above-mentioned wind power blade tip lightening suspender, risen in die process in wind electricity blade, the wind electricity blade
Blade tip suspender plays crossbeam suspender, when operation, first hangs on travelling crane hook the chain sling (5), is sling suspender with driving,
And be moved at wind power blade tip lightening above suspension centre, suspender belt is placed between blade and mold at the suspension centre, then by suspender belt both ends
It hangs on the opening lifting lug (31), blade can be lifted by crane, under such state, suspender belt is V-shape, it is possible to reduce blade
Rear stress avoids rear impaired, is such as used only as crossbeam suspender, can not install described wooden with type support plate (2)；In wind-powered electricity generation leaf
In piece punching, weighing process, the wind power blade tip lightening suspender plays support suspender, when operation, is first placed on the suspender
Lower section, wind electricity blade is moved on on the suspender from transfer tooling, is then hung at suspender belt both ends respectively at wind power blade tip lightening suspension centre
On the opening lifting lug (31), suspender belt intermediate hanging is such as used only as support suspender, can not install the chain sling on travelling crane hook
(5)。
