Introduction
The crusher upper main frame is the large structural component at the top of a cone crusher. In OEM spare parts manuals it is listed as the top shell. Procurement teams also search for it as an upper housing or upper frame, but all of these names point to the same part, and one unit is fitted per crusher.
Horbon manufactures replacement top shells as a factory-direct supplier. The frame is also used on CC300 and CC300S cone crushers. Because the part carries the upper structure of the machine, a replacement needs to match the OEM drawing at every interface, not just the overall outline. That is the problem this page helps you solve: identifying the correct frame, and knowing what else to check before you place an order.
Where the Top Shell Sits in the Machine
In the exploded views of the CC300 and CC300S manuals, the top shell sits in the upper structure of the crusher. The parts listed directly around it include:
- Spider cap and spider bushing, at the top of the machine
- Arm shields, fitted to the frame
- Concave ring, supplied in several chamber versions (EF, F, MF, MC, C, EC and M in the CC300 manual)
- Filler ring (MC / MF) and filler ring connecting plates
- Dowel pins and shims (shims are listed in t=1, t=3, t=5 and t=10 thicknesses)
- Liner, on the CC300S list
- Lubrication and oil connection parts: lubrication nipple, hoses, pipe couplings, elbows, air filter, plug and oil seal ring
- Fastening hardware: screws and washers
Seeing the crusher upper main frame as part of this group matters when you order. A replacement frame that is correct on its own can still cause problems if the surrounding parts come from a different drawing revision.
Key Advantages
-
Drawing-based matching. We work from your OEM Part Number or 3D drawing. If you only have the worn frame, we can start from the sample and work back to a drawing.
One-stop sourcing for the upper structure. The spider cap, arm shields, filler rings and connecting plates, and the related hardware shown in the manual can be quoted together with the frame, which reduces the number of suppliers you manage.
-
Suitable material and process options. Material is made per drawing or OEM requirement. Our general capabilities include high manganese steel, Cr-Mo alloy steel, precision casting, heat treatment and CNC machining.
Direct factory communication. Our site in Quzhou covers about 20 mu (approximately 13,000 square metres). You speak with the manufacturer, not a trading intermediary, and we have worked with 50–200 overseas customers.
Applications
Replacement top shells are used on cone crushers in:
- Mining operations that run cone crushers in the crushing circuit
- Quarries and aggregate plants
- Maintenance depots that rebuild or refurbish crushers
- Distributors and spare parts traders who need a consistent source for upper-structure parts

Frequently Asked Questions
1. What is a crusher upper main frame, and is it the same as a top shell?
Yes. Top shell is the name used in OEM parts lists for the large structural part at the top of a cone crusher. Buyers also call it the upper main frame, upper housing or upper frame.
2. Which machines does it fit?
We supply it for CC300 and CC300S cone crushers. For other cone crushers, send the model and Part Number or drawing.
3. What parts does the frame work with?
According to the OEM exploded views, it works with the spider cap, spider bushing, arm shields, concave ring, filler rings and connecting plates, along with dowels, shims and fasteners.
4. What is the difference between the top shell and the top shell assembly?
The top shell is the frame itself. The assembly is the frame plus the parts fitted to it. In the CC300S manual, the assembly is listed without the crushing components, so confirm the scope with us before ordering.
5. How do I identify the right frame?
Give us the crusher model, the Part Number from your manual, and, if available, a drawing or a photo with dimensions. We compare these against the OEM structure before quoting.
6. What should I inspect on the old frame before replacing it?
Look for cracks, deformation, worn seating surfaces and damaged bolt holes. If you want us to review, send photos together with the part number.
7. Does the concave chamber version matter?
The frame is matched by part number or drawing. Please still tell us the chamber version in use, such as MC or MF, so we can check the filler rings and connecting plates in the same quote.
8. Can I order the frame together with the spider cap and arm shields?
Yes. Send the full list and we quote the group together.
9. What do you need for a quote?
Crusher model, Part Number or drawing, quantity, and any parts you want quoted with the frame.
10. Do you provide installation guidance?
Yes. We provide installation guidance documents and can support by photo or video.
