It switchs the distance between (8) and transformer and is greater than 50cm；
There are four support rod (1) settings；
The upper frame (3) is rectangle；
The bolt A(2) 8 are provided with, two bolt A are arranged in the position that every support rod (1) connect with upper frame (3)
(2)；
Ring cover (11) and switch cover (10) is arranged in transformer top；
The connecting pin (9) is bolted on the ring cover (11) of transformer top, four connecting pins (9) point
Be not fixed on bolt B (12), bolt C(13), bolt D(14), bolt E(15) on.
The bolt B (12) is equal to bolt D(14 at a distance from bolt C(13)) it is 35cm at a distance from bolt E(15),
Bolt B (12) is equal to bolt C(13 at a distance from bolt E(15)) it is 66cm at a distance from bolt D(14)；The support rod
(1) height is 180cm, the long 66cm of the upper frame (3), width 35cm, and the cross bar (4) length is 66cm.
The upper frame (3) can also be using round or square.
The support rod (1) and upper frame (3), cross bar (4) use insulating bar or hem width for the angle bar of 6cm.
In use, turning on the switch lid (10) after connecting pin (9) are fixed to ring cover (11), being connected with load with lifting rope (7)
Hanging ring on tap switch (8), and lifting rope (7) is connect with suspension hook, start electric block (5), rises load ratio bridging switch (8)
To apart from transformer 50cm or more.
The utility model has the beneficial effects that: working efficiency greatly promotes, shorten maintenance (power failure) time；Improve maintenance
Safety during site operation；The security risk that crane enters substation is evaded；Eliminate employ crane expense and
Time reduces personnel's investment, reduces extraneous expense, economic value with higher.
