Product Description
The Crown CR 46128 Chain Assembly is a high-tensile alloy steel linkage component designed for Crown PTH50 manual pallet jacks (newer series, Serial #7-512501 and higher). This durable chain assembly transmits actuator motion from the handle to the hydraulic pump release valve, enabling smooth controlled lowering and raising of loads. Built to factory-spec standards for precise load transmission and superior fatigue resistance in demanding material handling environments.

Frequently Asked Questions
Q: What does the CR 46128 chain assembly do in a Crown pallet jack?
A: The CR 46128 is a high-tensile alloy steel linkage component that transmits motion from the handle to the hydraulic pump release valve, enabling controlled load lowering and raising in the hydraulic system.
Q: Which Crown models and serial numbers does the CR 46128 fit?
A: The CR 46128 is designed for Crown PTH50 newer series units with serial numbers 7-512501 and higher. It is not compatible with older PTH50 production batches or other Crown pallet jack models.
Q: What material is the CR 46128 chain assembly made from?
A: The CR 46128 is constructed from high-tensile alloy steel, which provides superior durability and fatigue resistance compared to standard carbon steel in demanding material handling applications.
Q: Why should I use the OEM CR 46128 instead of aftermarket chains?
A: The CR 46128 is engineered to exact Crown specifications for precise load transmission geometry and attachment angles. Aftermarket alternatives may have different link spacing or connector designs, causing misalignment, binding, or premature wear.
Q: Is the CR 46128 a complete replacement or part of a larger assembly?
A: The CR 46128 is an individual linkage component that may require removal of the handle assembly or hydraulic pump section for access. Verify your specific pallet jack configuration before ordering to ensure proper installation fit.
