SANY Crane Hoist Wire Rope

Main and auxiliary hoist wire rope for SANY STC-series truck cranes, specified from SANY's own product brochures rather than by tonnage. The export STC250 runs 16 mm rope (16-35W×7-1960) — 175 m on the main winch and 105 m on the auxiliary. The STC500 runs 18 mm (18-35W×7-1960), 220 m and 130 m. The STC800 and the later STC800S both run 20 mm (20-35W×7-1960), 245 m and 145 m. 35W×7 is a rotation-resistant construction and 1960 is the wire tensile grade in MPa: a rope of the same diameter but a different construction can let the hook block spin under load, so diameter alone is not a specification. The letters after the grade on the brochure designation (USS, USZ) code the finish and lay direction and are worth matching to the tag on the old reel. These figures come from export brochures; domestic C5-series builds are not covered by them, so confirm on the machine before ordering. Replace against the discard criteria in the operator manual — broken wires, diameter loss, kinks, birdcaging — not against hours, and check the drum and sheave grooves at the same time: a worn groove shortens the life of a new rope.
