Βαθμός 70 Μεταφορική Αλυσίδα
Transport chains are high strength chains used in applications where much strength is needed yet the task served is rather straightforward. Sometimes referred to as Βαθμός 70 binder chain, cargo chain, high-tensile chain, or trucking chain, this heavy-duty chain is designed for tie down applications. Βαθμός 70 αλυσίδα is never to be used for overhead lifting.
How is Chain Grade Measured?
Αλυσίδα grades are specified by the NACM (National Association of Chain Manufacturers) και
the ASTM (American Society for Testing and Materials) standards that define the dimensional, mechanical, and compositional requirements that determine the proof of the steel, minimum breaking force required, elongation, και τα λοιπά. The combination of these measures determines the working load limit that each heavy duty chain can handle before risk of breakage. These factors are tested in a laboratory setting to ensure chain load capacity.
Βαθμός 43 αλυσίδα, also known as Αλυσίδα υψηλής δοκιμής, is a mid-grade cargo chain with a working load limit of 5,400 lbs for 1/2″ αλυσίδα. Βαθμός 30 Αλυσίδα，also called αλυσίδα πηνίου απόδειξης，is a light to medium duty chain，Βαθμός 70, referred to as Μεταφορική Αλυσίδα, is top level of heavy chain with a working load limit as high as 11,300 lbs of cargo for 1/2″ αλυσίδα. Chain suppliers are required to clearly mark 5/16” and 3/8” chain links with their grade within 1 foot intervals along the truck chains, and within 3 foot intervals for ½” chain. This is to ensure easy identification and promote safety. It is very important to use the right heavy duty chain for the load you are transporting and these rules are D.O.T. enforced.
When to use Grade 70 Αλυσίδα
When you need heavy chain to secure large loads Βαθμός 70 αλυσίδα is the best choice. With the most efficient weight-to-strength ratio that comes from drop forging and heat treating, this truck chain allows you peace of mind that your load will be secured in place against sudden stops or tight turns where another transport chain could fail. Βαθμός 70 αλυσίδα και Βαθμός 70 chain hooks can be easily identified by their yellow zinc chromate finish and either 7, 70, ή 700 embossed into the surface. Βαθμός 70 αλυσίδα strength is mandatory for auto transport chains, flatbed chains, heavy equipment chains, tractor tie downs, and log transport chains.
Hooks for Transport Chain
There are three common types of hooks used for grade 70 transport chain.
- Clevis Grab Hook A shallow throat opening allows for easy and secure connections.
- Clevis Slip Hook Also referred to as a sling hook, is durable and features a wider throat than the clevis grab hooks.These hooks can be attached easily to chains, and allow more versatility within your tie down assembly.
- Clevis Slip Hook with Safety Latch Features a wider throat than a clevis grab hook; designed with a safety latch over the wide throat of the hook to ensure the chain is held in place.
Log Chain
Βαθμός 70 transport chain can be used as logging chain, however standard log chains rate at Βαθμός 43. Βαθμός 70 αλυσίδα is designed for tie-down use only, but will work for any logging operation. High test log chains are typically used for securement, binding, construction, logging, and agriculture, and our Βαθμός 70 transport chain is suitable for all of the above.
Chain Extension
A short section of αλυσίδα attached to the end of certain tie-down straps. These extensions include an eye grab hook on the end.
