What is meant by the term "blind lift"?

The term "blind lift" refers to a situation where the crane operator cannot see either the load being lifted or the path it will take during the lift. This can occur due to various obstructions, such as buildings, other equipment, or even when working from a vantage point that does not provide direct visibility of the load and its surroundings.

This definition highlights the critical nature of communication and signaling in ensuring safety during blind lifts. Effective crane signals from ground personnel become vital, as they help guide the operator regarding the position and movement of the load, mitigating the risk of accidents that can arise from poor visibility.

While low visibility conditions, nighttime operations, or unexpected obstacles can all contribute to challenges during lifting operations, they do not fully encompass the essence of what constitutes a blind lift. The defining characteristic is specifically the operator's inability to directly see the load or its trajectory, making clear communication with signalers indispensable in these scenarios.
