XCMG Crawler Crane Structural Link Assembly - Photo Reference
The pictured component is presented as a structural link assembly photo reference for XCMG crawler crane applications. Its exact installation position and part number are not confirmed from the image alone. A quotation should therefore be based on the machine serial number, the removed sample and dimensional evidence.
Role of a Pinned Structural Link
A heavy link with machined pin bores connects moving or load-transmitting members while allowing controlled articulation around a pin. Correct bore diameter, centre distance, width and installed orientation are essential. A visually similar link can still be unsuitable if its geometry, side clearance or pin arrangement differs.
Measurements Needed for Identification
Outside width and thickness at each eye
Diameter and usable width of both pin bores
Centre-to-centre distance between bores
Offset, step or side-profile dimensions
Original casting, stamping or painted reference marks
Installed-position photos showing neighbouring pins and brackets
Inspection Before Replacement
Clean the removed part before measuring. Check each bore for ovality, scoring, cracking around the eye, distorted side faces and abnormal contact marks. Also inspect the mating pins, bushings and brackets. Replacing a link without correcting worn mating components can leave excessive clearance or concentrate load at the new part.
Fitment Verification
Send the complete XCMG crane model and serial number together with several photographs of the assembly before removal. Measurements should be taken at more than one point when wear is visible. We do not infer material grade, heat treatment, load capacity or universal interchangeability from appearance. Those details must come from a confirmed component reference or approved technical record.
Packing for a Heavy Machined Component
Pin bores and machined faces should be protected from corrosion and impact. The assembly can be restrained on a pallet or in a reinforced plywood case according to its weight, with protective caps or wrapping around finished surfaces. The package label should show the confirmed reference, quantity and orientation for receiving inspection.
Frequently Asked Questions
Is a photograph enough to confirm this link assembly?
No. The installed position, serial number, bore diameters, overall width and centre distance are needed for a dependable comparison.
Should the pins and bushings also be checked?
Yes. Wear in mating pins, bushings or brackets can affect clearance and may need to be addressed with the link.
Can you quote when no part number is visible?
Identification may still be possible from machine data, multiple photos and accurate dimensions, but final confirmation is required before supply.
