Frequently Asked Questions
Q: What Crown equipment does CR 79904-A fit?
A: CR 79904-A is a chain assembly for Crown PTH manual pallet jacks with serial number 3-183850 and above. Verify your serial number is in this range before ordering. Earlier serial numbers may require the standard CR 79904 part instead.
Q: What is CR 79904-A made from?
A: CR 79904-A is manufactured from heat-treated carbon steel with an oil-impregnated corrosion inhibition surface finish. Heat treatment increases strength and hardness, while the corrosion inhibition finish extends service life in humid, wet, or outdoor storage conditions.
Q: How does CR 79904-A ensure reliable operation?
A: CR 79904-A is manufactured to precise tolerances and engineered as a control linkage component with 1.00 service factor. The heat-treated steel and corrosion-resistant finish maintain consistent dimensions and smooth actuation throughout the pallet jack service life without stretching, bending, or binding.
Q: Why is CR 79904-A classified as non-lifting?
A: CR 79904-A is a control linkage component, not a load-bearing element. Its function is to transmit mechanical control signals from the handle to the hydraulic system. Load is supported by the mast, pump, and hydraulic cylinder, not the control chain.
Q: How long does CR 79904-A last before replacement?
A: CR 79904-A is designed for extended service life with proper maintenance. The heat-treated carbon steel resists wear and fatigue. Replace if actuation becomes stiff, unresponsive, or if you observe visible bending, corrosion damage, or joint looseness.
