Hot Sale Offering Forging Hook 50t for Lifting Crane

Detailed Explanation
The most common kind of lifting gear in lifting machinery. Hooks are often suspended from the rope of the hoisting mechanism
by means of components such as pulley blocks.Hooks are divided into single hooks and double hooks by shape. They are
divided into forged hooks and laminated hooks by manufacturing method.
Single Hook manufacturing is simple, easy to use, but the force is not good, mostly used in the weight of 80 tons of the
following workplace; from the weight often used symmetrical double hook. The laminated hooks are made of a plurality of
steel plates which are cut and shaped, and the whole hooks are not damaged when the individual plates are cracked. The
safety is better, but the weight is large, mostly used in heavy lifting or lifting On the crane. Hooks are often impacted during
operation and are made of high quality carbon steel with good toughness. Hooks are extremely broad, generally include:
shackles, rings, rings, pear rings, long rings, combination rings, S hooks, nose hooks, American hooks hooks, eye hooks,
with insurance card rings Screw, Chain shackles, with a unique, innovative, high quality,safe features for factories, mines,
petroleum, chemical and ship terminals and so on. To ensure safety, quality and safety factor,static load to 3 times. With the
development of the machinery industry, the general hook has been unable to meet the lifting of large objects in the port, terminal,
sea operations and other environments, the hook from the rated weight of several thousand tons, or even tens of thousands
of tons, It is very important to use special materials. Forging hook commonly used materials are
20, DG20Mn, 35CrMo, DG34CrMo, 30Cr2Ni2Mo and so on.



Technical Requirement
1, the purchase of hooks should have the manufacturer's certificate and other technical documents can be used; important
departments to purchase hooks such as: railways, ports, etc., hook factory to be strict inspection (testing). Claw hook
2, the hook should not affect the safety performance of the defects; hook defects shall not be welded; hook surface should be
smooth, no cracks, folding, acute angle, burr, stripping, burning and other defects.
3, the shortest distance in the hook can be selected at two the appropriate location to print the mark is not easy to wear,
measure the distance of the mark, as the use of detection of openness is the basis for changes.
4, hook material can be used 20 high-quality carbon steel or hook special materials DG20Mn, DG34CrMo made of forging,
is strictly prohibited to use casting hook. Plate hook materials generally use A3, C3 ordinary carbon steel, or 16Mn low alloy
steel
5, homemade hook technical conditions should be consistent with GB 10051.1-88 ~ GB 10051.5-88 requirements (new
standards: GB10051.1-2010 ~ GB 10051.5-2010)
6, the hook's vertical axis, must be located in the rolling direction of the steel plate, and the hook does not allow splicing.
7, the hook application head rivet riveting, and in the hook and hanging objects hanging point of contact with high stress
bending parts shall not be connected with rivets.
8, plate hook between the film is not allowed to fully enclosed welding, only allowed to intermittent welding.
9, has been carried out on the overload test hook should be used for scrapping.
