Peerless alloy chain is rugged, versatile, high-strength, low-weight chain manufactured from special analysis alloy steel. It is quenched and tempered before proof testing and the ultimate tensile strength is over twice that of ordinary steel chain. Tensile strength following heat treatment meets or exceeds all existing OSHA, Government, NACM and ASTM specification requirements
Grade 30 Proof Coil is a general utility chain for industrial, farm and home applications.
Grade 43 High Test Chain features both high tensile strength and resistance to wear needed for load binding, logging, towing and other applications requiring a higher strength-to-weight ratio than Grade 30 Proof Coil chain.
Grade 70 Transport Chain is high strength and heat treated for use in load binding and other applications requiring a higher strength-to-weight ratio than both Grade 30 Proof Coil and Grade 43 High Test chain
General Safety Guidelines
Peerless Industrial Group, as a manufacturer of chain, can only control the specifications of our chain products in accordance with industry and governmental standards for chain manufacturing. It would be impossible for any warning to contain all of the possible misapplications associated with the use of Peerless Industrial Group products.
Our warnings are intended to identify only those risks which are most common. The responsibility and understanding of the proper safe use and application of the products in our catalog, ultimately rest with the end user.
We are not responsible for the end user’s assembly in which our chain may be used. Failure of the product can occur due to misapplication, abuse, intentional alteration or improper maintenance. Product failure can result in property damage, personal injury or death.Working Load Limit (WLL)
The "Working Load Limit” (rated capacity) is the maximum load that shall be applied in direct tension to an undamaged straight length of chain.Proof Test
The "Proof Test” (manufacturing test force) is a term designating the minimum tensile force which has been applied to a chain under constantly increasing force in direct tension during the manufacturing process.
These loads are manufacturing integrity tests and shall not be used as criteria for service or design purposes.Minimum Breaking Force
The "Minimum Breaking Force” is the minimum force at which the chain during manufacture has been found by testing to break when a constantly increasing force is applied in direct tension. Breaking force values are not guarantees that all chain segments will endure these loads. This test is a manufacturer’s attribute acceptance test and shall not be used as a criteria for service or design purposes.
The Working Load Limits and the associated safety factor of each Peerless product may be affected by wear, misuse, overloading, corrosion, deformation, intentional alteration and other use conditions. Regular inspection must be conducted to determine whether use can be continued at the assigned Working Load Limit, a reduced Working Load Limit or whether the product must be withdrawn from service. The terms "Working Load Limit”, "Proof Test” and "Minimum Breaking Force” contain no implication of what load the chain will withstand if the chain is used in such conditions of abuse and misuse. Peerless Industrial Group accepts no liability for any such abuse or misuse.
The Working Load Limit of a sling or assembly must not exceed the lowest Working Load Limit of the components in the sling or assembly. Use only Peerless Industrial Group approved parts as replacements when servicing or repairing original Peerless Industrial Group slings or assemblies.
USE ONLY GRADE 80 OR GRADE 100 ALLOY CHAIN AND ATTACHMENTS FOR OVERHEAD LIFTING. Please see page 6 for more information regarding alloy chain Working Load Limits in relation to the angle of lift.
PEERLESS INDUSTRIAL GROUP PRODUCTS ARE INTENDED TO BE USED AT OR BELOW THE MAXIMUM WORKING LOAD LIMITS SPECIFIED IN CONSTANTLY INCREASING FORCE APPLICATIONS UNDER DIRECT TENSION OR IN A STRAIGHT LINE PULL.
SHOCK LOADING IS PROHIBITED AND SIDE LOADING MUST BE AVOIDED, AS IT EXERTS ADDITIONAL DYNAMIC FORCES OR LOADING WHICH THE PRODUCT IS NOT DESIGNED TO ACCOMMODATE.
THE CONDITIONS INVOLVING USE IN CERTAIN ENVIRONMENTAL SITUATIONS SUCH AS UNUSUAL (HIGH OR LOW) TEMPERATURE, CHEMICAL, ETC…, CAN CAUSE CHANGES IN CHAIN PERFORMANCE.
