Further improvement of the utility model is: described seat pipe is arranged on the upper mounted plate end of stretching out transformer substation framework crossbeam outside.

Further improvement of the utility model is: the top of described grafting steel pipe is welded with the hold-down arm perpendicular to grafting steel pipe, and the end of hold-down arm offers the hanging hole that hangs pulley.

Further improvement of the utility model is: described connecting device comprises bolt and the nut matching with bolt; The quantity of described nut is two, and the outside of upper mounted plate and bottom plate respectively arranges a nut.

Further improvement of the utility model is: described connecting device is at least two, is oppositely arranged on the two ends of base.

Owing to having adopted technique scheme, the technological advance that the utility model is obtained is as follows:

This apparatus structure of the utility model is simple, and cost is low, is easy to carry, and is easy to assembling, is applicable to, on transformer substation framework, lifting appliance is installed.

Base of the present utility model is the separated setting of upper mounted plate, bottom plate, by screw bolt and nut, coordinate upper mounted plate is connected with bottom plate, easy installation and removal, on transformer substation framework operating personnel not need undercarriage be dismantled and assembled movable base, this hanging apparatus is fixed on to the optional position of transformer substation framework crossbeam, conveniently equipment is directly hung and gets desired location.Because this hanging apparatus is fixed on transformer substation framework crossbeam, from the strut bar at transformer substation framework two ends away from, and seat pipe is arranged on the upper mounted plate end of stretching out transformer substation framework crossbeam outside, is difficult for bumping while hanging taking equipment, effectively prevents device damage.
