- Structural Integrity Maintained — A worn or cracked block support can compromise the alignment and stability of connected components; replacing it restores proper load distribution and positional accuracy.
- Authorized OEM Source — Sold by DHS Equipment as a verified Multiquip OEM part, so the part number you see is the part number you receive.
A block support is a structural mounting component that holds, positions, and stabilizes adjacent assemblies within the machine. It absorbs mechanical loads and maintains correct alignment between mating parts during operation. When a block support cracks, deforms, or wears, connected components can shift out of position, leading to accelerated wear on surrounding parts and inconsistent machine performance.
