Non-Rotating Wire Rope Python ® Hoist Non-Rotating Wire Rope 3-layer type, refer to page 10 Python® Hoist Compacted rope design with 17 outer- and 21 inner strands Outer strands have 7 compacted wires to enhance abrasion resistance The CORE IS PLASTIC COATED to prevent metal-to-metal contact of rope core to outer strands PLUS it locks in factory applied lubrication Inner strands are reversed lay to provide non-rotating properties Main Applications: Load line on construction tower cranes. Main- and auxiliary hoist line for tower- and overhead cranes as well as ship cranes which require a non-rotating rope for severe dynamic load conditions. Hoist is a medium strength non-rotating wire rope. Rope Characteristic: Constructed from 17 outer strands over a 2-layer 24 strand plastic coated core. The plastic coating prevents metal to metal contact between outer- and inner strands and thus nearly 100% reducing the chance of undetectable inner wire- or strand failures. Plus, the plastic shield locks in factory applied core lubrication. That is pretty fancy, I say ! This rope is recommended for applications with high dynamic fatigue loads where otherwise the core might fail. The plastic core shield acts like a shock absorber much like in other Python® rope types. Python® Hoist requires grooved drums, preferable with LEBUS grooving. Python® Hoist ropes are classified as NON-ROTATING YES, Python® Hoist ropes can be used with a swivel at the end. In fact, we suggest you use a swivel during installation and the 'breakin' period to get the rope settled. After the break in period you can lock the swivel to stabilize the rope. ✔ O.K. to use When properly used Python® Hoist is stable against block twisting. Fleet angles, small sheaves, small line spacing, low block weight will negatively impact this characteristic. -32-
Non-Rotating Wire Rope Breaking Strengths Note: The maximum CAPACITY, WORKING LOAD LIMIT (WLL), or LINE PULL of the rope usually is 1/5 of the below stated values. For specific information consult the standards applicable to your rope application. Non-Rotating Crane Wire Rope with a plastic coated core Construction: 38 x 7 Class 34 x 7 Medium strength, high fatigue resistant nonrotating type. Compacting increases strength and sheave contact area. The plastic coated core increases fatigue life and prevents premature inner wire breaks as well as providing for permanent core lubrication. ALLOWED to be used with a swivel. Increased contact points between rope and sheave results in less internal rope pressure and less rope and sheave wear.
