Structural Strength Limitations: Aluminum alloys have lower strength and rigidity than steel, making them unsuitable for lifting extremely heavy objects, objects subject to strong impacts, or lifting very high heights.
Abrasion Resistance Limitations: The abrasion resistance of the inner wall of the aluminum alloy casing is inferior to that of manganese steel plates. Wear-resistant liners may be required in areas of high material impact.
Higher Cost than All-Carbon Steel: Manufacturing costs are typically higher than for hoists with ordinary carbon steel casings.
