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

1. Within the working range of the lifting electromagnet, (R<5M) is not allowed to stand.2. When the lifting electromagnet is lowered, it must not fall, so as not to damage the coil.3. Metals with a temperature above 200 degrees Celsius are generally not allowed to be lifted. When lifting a metal of

Inspired by the Oersted current magnetic effect experiment and a series of other experiments, Ampere realized that the essence of the magnetic phenomenon is the current, and the various interactions involving the current and the magnet are attributed to the interaction between the currents, and the

Ampere's linear current is also applicable to a small linear current. The ring current can be seen as a series of small linear currents. For each small segment of the linear current, the amperometric rule of the linear current determines the direction of the magnetic induction intensity on the centr
