When said steady pin I and steady pin II were separately fixed in positioning hole I and the positioning hole II, the spacing between said main pincers and back-up tong was at least 650mm.
Said bracket at tail part is " n " type structure.
Said upper and lower spring base is " H " type structure.
Said hydraulic transmission comprises hydraulic cylinder and group plate, and said hydraulic cylinder comprises cylinder body and piston rod, and the front end of said piston rod is fixedly connected with Hubei Province grillage of back-up tong through dialling plate, and said hydraulic transmission is fixed on the below of housing.
Said housing is made up of two laminated planks up and down, about said hydraulic transmission is fixed between two laminated planks.
Ultimate range between main pincers of the present invention and back-up tong is at least 650mm, can be applicable to oil, the sleeve pipe of clip lengthening, has replaced external like product, has filled up domestic blank, has reduced operating cost; Adopted the bracket at tail part of " n " type simultaneously,, made overall construction design more reasonable, for engineer operation provides safety guarantee increasing the steadiness that guarantees Power Tong between main pincers and back-up tong in the distance.
