MO M550-1

Frequently Asked Questions

Q: Which Mobile pallet jack models use the MO M550-1 pillar block?
A: The MO M550-1 pillar block is designed for manual pallet jacks made by Mobile, specifically the ML45 Mini and ML45 Miney models. Verify equipment model before ordering.

Q: What is the function of a pillar block in a pallet jack?
A: The pillar block is a load-bearing support component that stabilizes the vertical lift mast and maintains alignment of the carriage during raising and lowering. It carries a portion of the load and prevents lateral drift.

Q: What symptoms suggest the MO M550-1 pillar block needs replacement?
A: Replace the pillar block if the mast binds or sticks during lift, if you observe visible cracks or permanent warping, if the mast tilts to one side, or if there is excessive lateral play in the carriage assembly.

Q: Is the MO M550-1 compatible with electric pallet jack variants?
A: The MO M550-1 is engineered for manual pallet jack systems. Do not assume compatibility with electric or semi-electric Mobile models without explicit verification against the equipment manual.

Q: What material properties make the pillar block suitable for load-bearing applications?
A: The MO M550-1 is typically fabricated from cast iron or ductile iron, providing high compressive strength and wear resistance. This material withstands repeated vertical loading and maintains dimensional stability over extended service life.

Q: Can the MO M550-1 pillar block be interchanged with parts from other equipment brands?
A: The MO M550-1 is specific to Mobile ML45 Mini and Miney pallet jacks. Cross-compatibility with Crown, Toyota, Raymond, or other brands is not guaranteed. Dimension and mounting configuration verification is essential before attempting any substitution.
