4426044 Original Excavator Radiator Lock Catch for Hitachi ZX200

Part number 4426044 is a genuine lock buckle produced by Hitachi Construction Machinery in Japan. The support chain (chain rail joint) system used for crawler excavators is usually a quick release locking buckle used to lock the chain rail joint cover plate, grease nozzle dust cap, or tensioning device inspection hole cover. Therefore, it is mainly suitable for Hitachi ZX200 series (such as ZX200-3, ZX200-5G) and other tracked medium-sized excavators, and is universal on the same platform models with the same support chain structure

This product is a disposable quick release lock buckle specifically designed for supporting chain systems. The main body is a buckle structure made of black high-strength engineering plastic, usually consisting of a male buckle and a female buckle, which is locked with a "click" sound. Its design enables it to provide reliable locking force even in harsh environments with high vibration and muddy water, preventing the cover plate from loosening due to vibration. The packaging specification is 5 pieces per set, making it easy to replace multiple points on a single chassis side at the same time. Its core function is to fix various inspection covers or protective parts on the support chain in a convenient and reliable way, making it an ideal fixing solution for frequently disassembled components in daily maintenance.

Installation and replacement: 1 Cleaning: Clean the installation holes and contact surfaces of the lock buckle before installation. 2. Align and press: Align the male and female parts of the lock buckle, press vertically until a clear "click" locking sound is heard, indicating that it is installed in place. 3. Disassembly: When disassembling, it is usually necessary to use a tool (such as a flat head screwdriver) to press down on the release tab in the center of the lock buckle before it can be separated. Inspection cycle: Every 250 working hours, when maintaining the support chain, check whether all such locks are effectively locked, whether they are broken or have aged and lost their elasticity.
