Frequently Asked Questions
Q: What is the CR 44570 spring and where is it used?
A: The CR 44570 is a Crown OEM spring component for manual pallet jack hydraulic handle return assembly. This spring is engineered to return the hydraulic handle to its neutral position after each lift or lower cycle.
Q: Which Crown pallet jack models use the CR 44570 spring?
A: The CR 44570 is designed for Crown PTH 50 newer series pallet jacks, specifically serial numbers 7-512501 and up. Verify your equipment serial number before ordering to confirm compatibility.
Q: What is the material specification for the CR 44570?
A: The CR 44570 is manufactured from high-carbon steel conforming to ASTM A229 specification, with yellow chromate plating for corrosion resistance. This material choice provides reliable spring action in warehouse environments with exposure to humidity and cleaning agents.
Q: What load capacity is the CR 44570 rated for?
A: The CR 44570 is engineered for service on Crown PTH 50 manual pallet jacks rated up to 5000 lbs. This spring force is calibrated specifically for the resistance and return characteristics of that model series.
Q: What indicates the CR 44570 spring needs replacement?
A: Signs of spring failure include sluggish or incomplete handle return to neutral, handle remaining stuck in partial lift or lower position, loss of spring tension requiring extra force to operate, or visible corrosion damage to the plating. A failed spring compromises pallet jack operability and should be replaced immediately.
Q: Is the CR 44570 the correct replacement for my pallet jack?
A: Confirm that your Crown PTH 50 serial number matches the range 7-512501 and up. The CR 44570 is designed specifically for newer series models. Do not substitute with springs from other model lines or manufacturers without verifying physical dimensions and spring rate compatibility.
