Traveling BlocksDesign Features:The side plates made of heavy steel provide a sufficient weight so that the wireline is kept taut when hoisting and lowering the empty elevator, facilitating the drum to wrap the line, speeding up the lowering of the unloaded tackle and prolonging the line service life. The sheave groove size and the contact surface radius of the bail conform to API 8A specification. Sheave grooves are medium-frequency induction hardened, prolonging the sheave service life. Sheaves and bearings of the traveling block may be interchanged with those of the crown block. |
