Chain block
Chain links are the connecting parts on the drive chain of a cross-beam grate. We supply this spare part to project requirements, with goods dispatched from the partner factory. Replacement parts from the same series can be supplied together.
How it matches the neighbouring spare parts
A cross-beam grate builds its grate surface on cross beams that carry the load; replaceable grate bars sit on the beams, the beam assembly uses heavy-duty connecting pins, and high-wear zones get separate wear plates. When replacing chain links, check the specifications against the adjacent parts at the same time to keep the fit and alignment right.
| Spare part | Position on the grate |
|---|---|
| Cross beam | Load-bearing beam forming the grate surface structure |
| Grate bar | Replaceable part mounted on the cross beam |
| Connecting pin | Heavy-duty pin used in the cross-beam assembly |
| Wear plate | Protective plate for high-wear zones |
Available materials
| Application | Material |
|---|---|
| Cross beams and grate bars | Cr25Ni20 (310S) cast alloy steel |
| Medium-temperature zones | Cr26Ni12 |
| Structural support parts | Standard carbon steel |
Materials can be tailored to customer requirements, and the grades available include HT200, HT250, RTSi5, RQTSi5, RTCr16, RTCr, RTCr2, RTCr5 and RTCr2Si4Mo. Higher-temperature locations take cast alloy steel, medium-temperature zones take Cr26Ni12, and structural parts that mainly carry load use standard carbon steel.
Casting and dimension checks
Every part goes through precision casting and machining so that fit and alignment come out right. The product meets technical standard NB/T 47050-2016, and dimensions can be customised to customer requirements. Supplying original drawings or actual measurements at the ordering stage shortens spare-part confirmation.
