Material
Our wildcat cast from medium-strength carbon steel castings to provide a surface hardness of approximately 150HB

Terms of cable-lifter

chain groove—circumferential groove at the chain centerline to provide clearance for links passing normal to the wildcat shaft centerline.
chain pockets—recesses between the flanges and whelps into which links with flat side orientated parallel to the wildcat shaft centerling lay.
detachable link—a “C” shaped link, closed by means of a pair of closing pieces and a taper pin, and used to join anchor chain lengths and appendages into a continuous length aboard ship.
flanges—circumferential rims on the outside of the whelps, chain pockets, and chain groove.
link grip—the inside dimension of a chain link representing the effective length of a chain link in an assembled chain. Generally four times the nominal size of a stud link anchor chain.
whelps—protrusions on the inside of the flanges of the wildcat that resemble gear teeth and of such shape and dimensions so as to follow the path of the chain, as it enters and leaves the wildcat. Faces of protrusions are separated by the chain groove to permit links with the flat side normal to the wildcat shaft centerline to pass, but blocking links with the flat side oriented parallel to the wildcat shaft centerline.
wildcat—a rotating member specially contoured to receive assembled chain links and connecting links around the
circumference of the member and of suitable strength to impart motion to the chain when rotated.

Chain warping Test Methods
Measure the size of the anchor gyspy with the corresponding measuring tool
Check and check the grade and material certificate of the material used for the cable lifter
testing regulations
The inspection of the anchor gypsy is divided into type inspection and factory inspection.
Type inspection
a) First products of various modes:
b) Production and type identification of old products:
c) After formal production, due to major changes in structure, materials and processes, it is enough to affect performance:
d) Resume production after 4 years of production stoppage:
e) The factory inspection result is quite different from the previous type inspection result:
f) National quality supervision agencies have requirements.
