Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hoisting safety warning, more particularly to a building hoisting safety warning system. BACKGROUND

[0002] In the process of hoisting building materials by a crane, in order to ensure the safety of the hoisting operation of the crane, it is strictly prohibited to stand in the rotating radius of the crane during the hoisting operation of the crane. However, due to the lack of warning protection during the hoisting of the crane, pedestrians may mistakenly enter the rotating radius, which is a safety hazard. Their presence may distract the crane operator, increasing the difficulty and risk of operation. At the same time, if an emergency occurs, such as the crane losing control or the hoisted object falling off, these personnel will be in extreme danger.

[0003] In view of this, we propose a building hoisting safety warning system. CONTENT OF THE UTILITY MODEL
