What is a chain hook?
The chain hook is a device located at the end of the string that allows you to connect the string to the object. Made of heavy forged steel, the chain hook can be connected to the chain one of several methods. The chain hook can be connected by means of a split chain connection, welded chain connection, or Clevis. PIN Clevis is a preferred method of connecting the chain hook because it can be removed and replaced with another hook if necessary. The first is an open hook that has a wide gap in the hook. The open hook style allows it to be used to pull or lift an object similar to a hook found on a crane. With an open hook, ropes, Clevises and other chains, they can be placed inside the hook and raised or pulled. The second type of hook is a closed hook. This style of the hook is tight and is usually used to lock the hook into another chain link.
Some open style hooks are actually safety hooks. The safety chain hook has a metal PR attached to itDear flap. The clapper is mounted on the hook trail and bridges the gap into the hook point. As a string or similar object is placed on the hook, the flap is folded down, allowing the object to go through and rest in the stomach of the chain hook. Flapper then closed to prevent the object from coming out of the hook without first pressing the flap down and out of the way.
Some small chains, such as a dog string, use a spring clip in the hook that must be pushed down to remove the string. This is a smaller version of the safety hook. The hook of the safety chain is commonly found on construction sites or in other places where the crew and safety of passers -by are. Some manufacturers with spare parts sell conversion kits that turn regular hooks into safety hooks.
When connecting the chain hook to That has no hook, it is best to use clearvis. Clevis uses a screw that slips over the end connection of the string and screws into the fittings at the bottom of the hook. This methodIt creates the strongest form of building a string outside the division and re -evaluation of the link.
