Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
The upper load-bearing assembly comprising the spider body and parts supporting the top of the mainshaft.

Spider Assembly(Spider Assembly) is a gyratory crusher assembly. Verify its interfaces with adjacent mainshaft, spider, liner, eccentric and hydraulic system parts against the actual machine arrangement.
| Installation Position | At the top of the crusher, spanning the feed opening and secured to the top shell. |
| Main Function | Together, these parts withstand feed impact, support the upper mainshaft and protect the spider working surfaces and lubrication and sealing areas. |
| Part type | Parts / Assemblies |
Identify the assembly by more than its name. Check assembly numbers, part numbers and drawings for the spider body, cap, guards, bushing, oil seals, scraper rings and fasteners individually.
This page describes a generic equipment category. It does not establish direct interchangeability with any particular OEM model.
Confirm the brand, series, complete model, serial number, part number, drawings and operating conditions for the installed machine.
Submit the model, drawing number, drawings and operating conditions for review of the structure, material, manufacturing process and inspection requirements.
