Travelling Block Travelling Block Product Details: Application Oil Machine Type Drilling Equipment Processing Type Casting Material Stainless Steel Certification API Type Traveling Block Use Well Drilling Main features: The side plate of traveling block is thick steel plate. Its mass is strong enough. When lifting and lowering down an empty elevator, the wire line is in a tension status. It is good for line winding and empty hook lowering speed, and for prolonging the service life of the line. Sheave grooves has been quenched at intermediate frequency to decrease the wearing speed of line. There are double row tapered roller bearings installed in pulley holes, and each bearing has its own lube oil passage. Traveling block sheaves and bearings are interchangeable with that of the matched crown block.Item Model YC170 YC225 YC315 YC450 YC675 YC900 Max. hook load kN 1700 2250 3150 4500 6750 9000 Qty. of sheaves 5 5 6 6 7 7 Sheave O.D. mm 915 1120 1270 1524 1524 1830 Diameter of wire line mm 29 29,32 32,35 35,38 45 52 Overall size L mm 2000 2294 2580 3075 3010 3740 W mm 1004 1190 1350 1600 1605 1920 H mm 630 630 800 800 980 1280 Weight kg 2790 3805 6842 8135 9738 1822 5
