The Precise Choice: Consideration Ways For The Height Of Spider Lifts Make High - Altitude Operations Safe And Efficient Selecting the height of a spider lift is the key to ensuring the smooth progress of high - altitude operations. First of all, base it on the height of the operation target. When working on the exterior walls of a multi - storey building, measure the distance from the ground to the highest operation point of the building. For example, for a common 10 - storey residential building with a height of approximately 30 meters, the working height of the spider lift needs to cover this range, and an appropriate margin should be reserved to handle special parts such as the eaves at the top. For the inspection of the bottom of a bridge, measure the height from the bottom of the bridge to the ground to determine the height requirement of the spider lift. Secondly, consider the operation environment. When operating in narrow streets or indoor spaces, even if the height requirement is not high, the total height of the spider lift after extension should not touch surrounding obstacles, such as indoor ceilings and wires beside the street. Moreover, the flatness and load - bearing capacity of the ground also have an impact. Soft ground may limit the safe operation height of the spider lift, while solid ground allows for a higher extension. Finally, follow the safety regulations. Different regions have relevant laws and regulations regarding the height of high - altitude operation equipment. For example, the maximum operation height of spider lifts in areas near airports or specific urban areas is restricted, which is an important criterion for ensuring public safety. Selecting a spider lift with an appropriate height is an important guarantee for the safety and success of high - altitude operations.
