256HC Mast Section the construction company guarantee the low-voltage live line operation of tower crane
380V power supply is mostly used in tower crane construction site, but there are also some low-voltage work to be done. Low voltage live work shall be supervised by a specially assigned person, and tools with insulating handle shall be used during maintenance of tower crane. When working, wear insulating gloves and safety helmets on the dry insulating materials, wear long sleeved clothes, and prohibit using files, metal rulers, brushes with metal materials and other tools.

On the low-voltage live line erected at the same time of high and low voltage, the distance from the high-voltage line shall be checked. Take measures to prevent accidental contact with high-voltage wires.
Safety operation procedures
The driver and the crane operator must strictly implement the relevant provisions of the operation and use regulations of tower crane, and the driver and the crane operator must be assessed according to the relevant provisions of the provincial security inspection department and obtain the qualification certificate.
The driver must understand the working principle of the operation, be familiar with the structure of the tower crane, the function of the safety device and its adjustment method, master the operation methods of various performances of the crane and the maintenance technology of the crane.

Before the insulation measures are taken for the low-voltage live wire, the staff shall not cross it. In the work of live low-voltage power distribution device, it is necessary to ensure that between human body and the earth. Between human body and surrounding metal. There are good isolation measures between human body and other conductors or parts. Clear the phase, neutral line and select the working position before mounting the pole. When the conductor is disconnected, due to the small distance between low voltage phases, attention shall be paid to prevent the human body from contacting two wire ends at the same time.
Safe construction to ensure safe operation of tower crane construction site. It is the common aspiration of each construction site and tower crane manufacturer. It must be carried out in strict accordance with the technical regulations of tower crane.
