description The utility model relates to a rotation limiting device specifically is applicable to mobile concrete pump cantilever crane rotation mechanism. A rotation limiting device, is including gyration spacer pin axle, left side gyration limit switch, fixed tower base, branch adapted limit switch, electric limiting stop lever, mechanical limit stop, spacer pin axle slide, right side gyration limit switch, the welding of spacer pin axle slide is on the fixed tower base, and left gyration limit switch, branch adapted limit switch and right side gyration limit switch pass through the bolt fastening and on the fixed tower base, turn round the spacer pin axle and slide in spacer pin axle slide, the welding of machinery limit stop is on the pump truck capstan head, electric limiting stop lever and mechanical limit stop are connected. The utility model discloses a rotation limiting device has mechanical stop device to work after the electric spacing inefficacy, prevents the unrestrictedly disconnected cantilever crane oil p
