Product Overview

The XCMG crane sheave is the grooved wheel that carries and guides the hoist rope on an XCMG crane. It sits at the boom tip, in the hook block or on the jib, turning with the rope so the wire runs in a controlled path instead of rubbing across a fixed surface. We supply this sheave as a replacement wheel for XCMG crawler cranes and other heavy machinery, in cast steel or nylon, with the groove and centre bore made to your drawing or sample.

A sheave is a small part with a large effect on rope life. A worn groove, a rough edge or a bore that does not sit square on its pin will wear the wire rope, alter the rope path and shorten the working life of both parts. This is why we quote from dimensions rather than from a photograph alone: outside diameter, groove profile, bore, hub width and mounting arrangement all have to agree with the assembly on your crane.

The wheel is a solid circular body with a wide centre opening, finished in red and supplied with the machined groove ready for the rope. It is not a complete hook block or boom assembly; it is the sheave itself, and we can identify the bearing, bushing or pin separately once we know how your assembly is built.

Customers order this sheave for a single replacement after groove wear, for a planned boom overhaul, or as a spare held in the workshop. We also take drawing-based work where the original XCMG reference is no longer readable and the old wheel has to be measured instead. If you are sourcing construction machinery spare parts for a mixed fleet, the same order can include other items from our range.

Materials & Groove Build

• Two materials for the same XCMG crane sheave: Cast steel is the usual choice for main hoist and boom tip positions where load, shock and abrasive grit are part of the job. Nylon is used where a lighter, corrosion-resistant wheel is preferred and the rope load is within its working range.
• Steel grades matched to the duty: Steel sheaves can be produced in the alloy grades we use across our construction machinery spare parts range, including 35SiMn, 35SiMnMo and 28CrMnMo. The grade and heat treatment are agreed before machining, because wear resistance and load capacity depend on both.
• Groove cut to the rope: The groove profile is machined to the wire rope diameter you specify, with the edges dressed so the rope is not cut or scored. A groove that is too wide lets the rope sit low; one that is too sharp wears the wire.
• Bore and hub machined as a set: The wide centre bore, hub faces and outside diameter are checked together so the wheel sits square on its pin. A bore that is off-centre will make the sheave run out and load the rope unevenly.
• Protective finish outside the groove: The wheel is finished in red for identification and surface protection, while the groove is left clean for rope contact. The finish does not replace the correct material or heat treatment.
• New material only: We do not rebuild a worn sheave or cut a new groove into a used wheel. Steel and nylon start from new stock, and the material is confirmed against your application before production.

Drawing & Fit Measurements

1. Record the XCMG model, serial number and the reference on the old sheave if it is still readable. A photo of the machine nameplate helps us keep the file straight and match the right crane spare parts to the machine.
2. Measure the outside diameter across the full wheel, then the groove diameter at the bottom of the rope seat. Do not measure only the outer edge; the rope sits deeper in the groove.
3. Measure the centre bore and the hub width. If the sheave runs on a bearing or bushing, measure the bore with the insert removed and note the insert type.
4. Measure the overall width, the thickness at the rim and the position of any spacer, flange or retaining ring. These dimensions decide whether the wheel sits centred in the block.
5. Note the wire rope diameter and construction, and photograph the old groove with the rope removed. A worn groove can look wider than it was when new, so send the rope size as well.
6. Send a drawing if you have one, in PDF, DWG or a dimensioned sketch. Mark the critical dimensions and the material you want, and we will review the drawing before quoting.
7. For a multi-sheave block, count the wheels and identify the position of each one. Sheaves in the same block can differ, so number them before you send photos.
8. If you only have the crane model, send photos of the old part from several angles with a tape measure visible. We will tell you which dimensions are still missing.

XCMG Compatibility & Fit Confirmation

As a crane parts supplier, we know an XCMG crane sheave is not selected by model alone. The same model can carry different wheels at the boom tip, hook block and jib, and a previous repair may have changed the block. The reference that matters is the one on the wheel you are replacing, together with the measured groove and bore.

Start with the crane model, serial number and any number stamped on the old sheave, such as 171700536. If the stamping is worn, send a photo of the wheel face and the mounting side. We use those details to check the part against the drawing and to see whether the block uses a bearing, bushing or plain bore.

If the crane has been repaired before, compare the fitted wheel with the other sheaves in the same block. Mixed parts can sit at the wrong height or run with a different rope path. A photo of the complete block helps us catch that before you order.

For a current XCMG model, the model and serial number are usually enough to start the search. For a wheel that has been modified or rebuilt, the old part must be measured. We would rather ask for one more photo than supply a sheave that looks close but runs badly.

Applications & Duty

• Boom tip hoist sheaves: The wheel at the boom head guides the main or auxiliary hoist rope down to the hook block. Groove wear here changes the rope path and should be checked during boom inspection.
• Hook block and travelling block: Sheaves inside the block carry the rope over multiple falls. A matched set of these crane spare parts keeps the rope centred and avoids one wheel taking more load than the others.
• Luffing jib and auxiliary sheaves: Smaller wheels on the jib or auxiliary system are often overlooked until the rope starts to jump. Replace them with the same rope diameter and mounting detail.
• Crawler crane boom maintenance: During a planned boom overhaul, sheaves are usually replaced together with wire rope, pins and bushings. Ordering these construction machinery spare parts as a set reduces repeat dismantling.
• Quarry and construction site duty: Grit, dust and impact shorten sheave life. Cast steel is normally preferred where the wheel sees shock load and abrasive material.
• Port, yard and bridge projects: High-cycle hoisting benefits from a smooth groove and a wheel that runs true. Check alignment and rope condition when a new sheave is fitted.

Installation & Maintenance

1. Clean the block, pin and bushing before fitting the new sheave. Grit left on the pin will make the wheel run off-centre.
2. Check the groove against the rope and confirm the bore fits the pin or bearing without force. The sheave should sit square, with the correct spacer or retaining ring in place.
3. Align the sheave with the lead-in rope so the wire enters and leaves the groove without rubbing the flange. Check the rope path through the whole block, not only at the new wheel.
4. Rotate the sheave by hand after assembly. It should turn freely with no bind, rock or contact with the block side plates.
5. Run the crane through a slow hoist cycle and watch the rope seat in the groove. Stop if the rope jumps, twists or rubs against a shoulder.
6. During routine inspection, look for a polished groove, a step at the groove edge, cracks around the bore and rope wear. A groove that has become too wide or sharp means the sheave or rope needs attention.
7. Keep the groove clean and follow the rope manufacturer's lubrication instruction. Do not pack grease into a nylon sheave groove unless the rope maker specifies it.
8. After the first working shifts, recheck the retaining ring, mounting bolts and rope condition. Re-torque fasteners to the crane manufacturer's figure, not a generic value.

Arrival Inspection

• Inspect the crate before you sign for it: look for crushed corners, split boards, water staining or a broken brace, and note any damage on the delivery receipt. Photograph the crate as it arrived, then unpack and photograph the wheel again before the packaging is cleared away.
• Lift the wheel by the hub or the outer rim with a sling or strap, never by the rope groove, and do not drop it onto concrete. A cast steel wheel can chip at the rim and a nylon wheel can crack at the bore even when the impact looks minor.
• Check both faces of the wheel once it is out of the crate: the red finish should be intact, the groove clean and dry, the groove edges free of burrs, and the bore free of tool marks or bright rub marks from movement in transit.
• Measure it before fitting. Use a caliper for the outside diameter, the groove diameter at the bottom of the rope seat, the bore and the hub width, then compare those figures with the drawing or the values you ordered. If the old wheel is still on the bench, stand the two side by side: a difference in groove depth or hub width is easy to see.
• Check that the wheel runs true. Mount it on a clean pin or mandrel, or lay it flat on a surface plate; a wheel that rocks, or shows visible runout at the rim, should not go into service.
• Seat a short length of the actual wire rope in the groove. The rope should sit with its top roughly level with the rim flanges and should not rub either flange. If the rope sits low or rides on the flanges, stop and send us a photo of the rope seated in the groove.
• Keep a record of what arrived: photograph the wheel face, the bore and the groove with a tape measure in shot, and file the set with the machine history. If a mismatch or a warranty question comes up later, these photos and the measured values resolve it far faster than a description.
• If anything does not match the order, do not fit the wheel. Contact us with the photos and measurements first, because wear or load marks from service make it harder to establish the condition in which the sheave was supplied.
• Store spare wheels flat and off the ground in a dry place, with the groove lightly protected against rust, and keep nylon wheels out of direct sun and away from heat sources until they are needed.

Technical Support & Model Matching

Not sure which part fits your machine? Send the part number, the machine model, and a photo of the nameplate or the worn item, and our engineers — each with more than ten years in the construction machinery business — will confirm the correct reference and quote it. We advise on installation, help trace faults, and answer technical questions before and after dispatch. Since 2017 we have built this support on a supplier network covering FUWA, SANY, XCMG and ZOOMLION, so older and hard-to-find references can usually still be sourced.
