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

Application of sling and hoisting technology in the construction of the substationAt present, as the assembly requirements of substations are gradually becoming higher, relevant requirements for hoisting during the construction of substations have also increased. In the specific operation, work incl

Hazard analysis of lifting slings in large hoisting machineryIn order to successfully use large-scale hoisting machinery to complete the lifting tasks, it is necessary to analyze the dangerous factors in the lifting process of the large-scale hoisting technology analysis, analyze the construction en

Sling companies must have a clear understanding of product cost managementTo solve the problems in the production cost management of the sling manufacturing enterprise, it is necessary to combine the actual situation of the enterprise and propose an optimized strategy in a targeted manner.First of a

Quick selection method of temporary lifting slingWhen hoisting, rotating, moving vertically, or horizontally on equipment or parts at the construction site, wire ropes, shackles, and on-site hoisting lugs are commonly used for hoisting slings and hoisting machines. At the production site, people pay
