Frequently Asked Questions
Q: What is a roller column and what does CT 973330 do?
A: CT 973330 is a roller column assembly for Caterpillar electric lift trucks. Roller columns support and guide the mast during lowering and raising operations. This component is part of the lift mechanism and must be compatible with your specific truck model and mast configuration.
Q: Which Caterpillar lift truck models use CT 973330?
A: CT 973330 is designed for Caterpillar electric lift trucks. Provide your equipment model number and year to confirm this roller column matches your truck configuration. Mast assemblies and roller columns vary across model series.
Q: What are the dimensions and material specifications for CT 973330?
A: Provide your lift truck model details for exact dimension and material specifications. Roller columns must match mast width, height, and channel dimensions precisely. We will confirm the correct specifications once we identify your equipment.
Q: How long does a roller column typically last in service?
A: Roller column lifespan depends on load intensity, operating conditions, and maintenance. Heavy daily use and rough handling accelerate roller wear. Regular mast cleaning and lubrication extend roller column life. Replace CT 973330 when rollers bind, misalign, or cause mast binding during raise or lower cycles.
Q: What failure symptoms indicate a roller column needs replacement?
A: Replace CT 973330 if you notice mast binding during raise or lower, uneven mast movement, noise or grinding sounds from the mast assembly, or visible roller damage or misalignment. Continued operation with a failed roller column can damage the mast.
