The anchor chain is formed by a plurality of chain links, and the size is expressed by a chain diameter of about (mm). According to whether there is a support in the middle of the link, it is divided into a chain anchor chain and a non-stop anchor chain. The anchor chain can be made by forging, cast

The anchor chain has to work. The most basic condition is to hook things on the seabed. If the anchor chain is not long enough, the anchor will not work. If the bottom of the sea is flat, or if the hook is not fixed, or the hook is not strong, if it is calm, if the waves are too large, the anchor w

At the front end of the chain, a section of the anchor chain whose ES is directly connected to the anchor shackle of the anchor is the first section of the chain. In addition to ordinary links, there are generally anchor chain attachments such as end shackles, end links, enlarged links and swivels,

The Chain Link includes the Common Link (C), the Enlarged Link (EL), the Open End Link (E), the Swivel (Swivel, SW), and the End Link. D Type End Shackle (ES), connecting link (KS) or connecting shackle (JS). The size of each link is indicated by the diameter of the round steel of the link, as shown

According to the structure of the link, the anchor chain can be divided into two types: Stud Chain and Studless Chain. The link chain of the chain anchor chain (Fig. 1) is provided with a crosspiece. When the size and material are the same, the strength of the chain is larger than that of the unchai

The Chain Cable is a steel chain that connects the hull to the anchor. The main function of the anchor chain is to connect the anchor to the ship and transmit the anchoring force of the anchor to the hull. When anchoring, the anchor chain has a certain weight, which can play a certain role in the wa

Anchor chain refers to a special chain that connects the anchor and the hull and transmits the anchor grip. Often composed of anchor chain links, intermediate links and end links. According to the structure of the link, it can be divided into two types: the chain anchor chain and the non-stop anchor

1. Do not use objects other than steel.2. Not used for objects with too high hardness.3. Objects with irregular slopes may not be used for vertical lifting.4. It is not possible to use vertical cranes in the case of horizontal bite.5, the vertical crane can not hang more than 2 overlapping objects.6

1. Suspension and loading operations shall be carried out by qualified personnel for hanging and hanging operations.2. Select the tongs that match the purpose.3. Use within the allowable load range and must not be overloaded.4. Use within the allowable thickness range.5. Do not enter the lifting wor

In the lifting work, due to the cultural level of the operators and the actual situation on the spot, the calculation formula of the regular lifting force is inconvenient to operate, and the measurement and calculation are relatively cumbersome. Here to introduce a simple, practical and easy to oper
