Lebus L-170 Series General Purpose Snatch Block - 5 Ton - 4-1/8 in Sheave

Description du produit

The Lebus L-170 Series General Purpose Snatch Block is a bronze bushing bearing snatch block designed for use in winching, rigging, pulling, and load positioning applications requiring a rated working load of 5 ton, compatible with manila rope and wire rope cable across a range from 3/8 inch to a maximum of 1-1/4 inch diameter, identified by part number 599828. The snatch block is a single-sheave pulley block with an openable side plate that allows the rope to be inserted into the sheave groove without threading the rope end through the block, making it practical for field rigging applications where the rope is already in place or where threading the rope end is not feasible. By redirecting the rope through the snatch block, the operator can change the direction of pull from a winch or pulling device, create a mechanical advantage when the block is used in a purchase system, and extend the effective reach of a winching or pulling operation beyond the direct line between the winch and the load.

The general purpose designation and the extended cable range of 3/8 inch to 1-1/4 inch maximum diameter distinguish this block from the L-170 Series 599800 block rated for 3/8 to 1/2 inch rope. The wider rope diameter range of part number 599828 accommodates larger diameter manila rope commonly used in marine, agricultural, theatrical, and traditional rigging applications where rope diameters up to 1-1/4 inch are standard, providing a single block that can serve a broader range of rope sizes without requiring a dedicated block for each rope diameter. The 4-1/8 inch sheave outside diameter and the 5 ton working load limit apply across the full compatible rope diameter range, and the correct rope size for the specific application must be selected to ensure the rope seats correctly in the sheave groove and the assembly working load does not exceed the rated capacity of the weakest component in the rigging system.

The dual manila and wire rope compatibility of the L-170 Series makes this block suitable for applications where natural fiber rope is used alongside or in place of wire rope. The bronze bushing bearing sheave mounting provides a self-lubricating, corrosion-resistant bearing surface well suited to outdoor, marine, and wet operating environments where roller bearings may be more susceptible to corrosion and contamination. Bronze bushing blocks are generally more tolerant of infrequent lubrication and exposure to moisture, mud, and contaminants than roller bearing blocks, making them a practical choice for field rigging and marine applications where maintenance access is limited and environmental exposure is high.

The snatch block must be inspected before each use for cracks or deformation of the block body and side plates, correct operation of the side plate opening and latching mechanism, sheave bushing condition and freedom of rotation, wear or grooving of the sheave groove surface, and correct attachment of the block hook or shackle to the anchor point. Any snatch block showing signs of damage, deformation, or bushing wear must be removed from service immediately. Manila rope used with this block must also be inspected before each use for deterioration, mold, abrasion damage, and loss of strength.

Key Features: Lebus L-170 Series general purpose snatch block Part number 599828 5 ton working load rating Compatible with manila rope and wire rope cable, 3/8 in to 1-1/4 in maximum diameter Wider rope diameter range than L-170 Series 599800 for greater versatility 4-1/8 in sheave outside diameter Bronze bushing bearing for corrosion resistance and self-lubrication Openable side plate for easy rope insertion without threading rope end Dual manila and wire rope compatibility for versatile general purpose rigging applications

Note: Always inspect snatch blocks and rope before each use and remove from service immediately if any damage, deformation, bushing wear, sheave wear, or rope deterioration is identified. Never exceed the rated working load of 5 ton. Always use with rope within the rated maximum diameter of 1-1/4 in. Manila rope has significantly lower working load limits and greater susceptibility to deterioration from moisture and UV exposure than wire rope — verify the working load limit of the specific rope in use before assembling the rigging. The snatch block anchor point must be rated to at least twice the working load of the pulling device when the block is used to redirect a single-part line. Lubricate the bronze bushing bearing at regular intervals per the manufacturer's maintenance schedule. Never use a snatch block as a substitute for a rated lifting block in overhead lifting applications unless the block is specifically rated and certified for overhead lifting use.
