What is the purpose of hold-down locks in an aerial apparatus?

The purpose of hold-down locks in an aerial apparatus is to prevent accidental deployment. These locks are critical safety features designed to ensure that the ladder or aerial device remains securely in place when not in use. By preventing accidental deployment, hold-down locks help protect personnel on the ground and those working on the aerial device, allowing for safe operation and minimizing the risk of unintended movement that could lead to accidents or injury.

In the context of aerial operations, safety is paramount, and hold-down locks act as a safeguard during both transport and operational phases, ensuring that the equipment remains secure until intentionally deployed. This feature is especially important in preventing the potential hazards that could arise from malfunctioning or unintended movements of the aerial device.
