LOAD CHAIN FOR L4LB090 ( # L4-841) & M3B

Product Description

The Kito Load Chain is a genuine OEM replacement component designed for use in Kito L4 LB Series lever hoists at the L4LB090 configuration and Kito M3B Series chain hoists, identified by part number L4-841. The load chain is the primary load-bearing element of both hoist types, transmitting the full working load between the load sheave and the lower hook assembly during every lift cycle. Maintaining a load chain that is in sound condition and within the manufacturer's wear tolerances is one of the most critical aspects of hoist inspection and maintenance, as a worn, damaged, or elongated chain is a direct risk to the safety of the lift and the personnel working in the area.

The load chain on both lever hoists and manual chain hoists is subject to wear, elongation, corrosion, and mechanical damage over its service life through repeated loading cycles, shock loading, side loading, and exposure to harsh operating environments including moisture, chemicals, abrasives, and extreme temperatures. Kito specifies maximum allowable elongation limits for each chain size and capacity class, and chains that have reached or exceeded these limits must be replaced immediately regardless of visible condition. Additional conditions requiring immediate chain replacement include twisted or kinked links, cracked or deformed links, gouges or nicks in the link surface, corrosion pitting that reduces the cross-sectional area of the chain wire, and any link that does not articulate freely through the load sheave.

Part number L4-841 confirms this chain is the correct OEM specification shared between the L4 LB Series L4LB090 lever hoist configuration and the M3B Series chain hoist, ensuring correct pitch, wire diameter, link geometry, and material grade for both hoist models. The cross-compatibility of this chain across both the L4 LB Series and M3B Series reflects a shared load sheave geometry and chain pitch specification between these two legacy Kito hoist lines. Using a genuine Kito OEM load chain maintains the full rated capacity and safe working load of the hoist following chain replacement.

Key Features: Genuine Kito OEM replacement load chain Compatible with Kito L4 LB Series lever hoist - L4LB090 configuration and M3B Series chain hoist Part number L4-841 Alloy steel construction to OEM specifications Ensures correct pitch, wire diameter, and link geometry for both compatible hoist models

Note: The L4 LB Series and M3B Series are legacy Kito hoist lines. Confirm current availability and part number L4-841 with your Kito distributor before ordering. Load chain replacement must be performed by a qualified hoist technician. The hoist must be fully inspected, function tested, and load tested before returning to service following chain replacement. Never splice, repair, or modify a load chain.
