Industrial lifting equipment requires careful consideration of characteristics and features due to the engagement of specific heavyweight or complex tasks. Hoisting applications mostly utilize the hooks with or without latches. The Occupational Safety and Health Act (OSHA) carefully guides the utility of various grab hooks according to users' work activity and safety.
Fabrication of a grab hook
Grab hooks utilize themselves to keep a chain from slipping off the hook. These types also include clevis and foundry hooks. The correct fitting of these chain components allows connection to chains' right size for holding the length of chains or sling formation. The slim U-gap prevents any slip and provides complete engagement. Grade 80 steel alloy is preferable for overhead lifting, and the higher-grade chain offers more strength and is abrasion-resistant.
Different types of grab hooks
There are mainly three types of grab hooks, namely, non-cradle, cradle, and chain shortening. The correct use of the styles mentioned above provides safety and reliability. Grab clasps do not have a latch. Non-cradle clamps are only applicable for overhead lifting when there is a twenty percent reduction in sling capacity. The alloy ones are particularly to secure loads at the end of the binder chain assemblies. Cradle grab hooks function without any capacity reduction. Chain shortening grab hooks have a deeper curve and are heavy.
Importance of grab hooks
The shallow opening of the grab hooks provides more manageable and secure connections. Each curve is befitting for different chain sizes. Although, the chain shortening grab hooks are the safest due to the more angular curve throat. The tip is more comprehensive and maintains the loading chains' rigging capacity. Grab clamps are valuable components that make single link adjustments to balance the load. Foundry hooks are the broad, deep throat grab clamps that are mostly for high-heat application tip loading. Standard grab hooks are less expensive but prone to failure than cradle grab hooks.
