Which type of ground surface poses the highest risk when operating a stacker?

Operating a stacker on bumpy and uneven surfaces poses the highest risk due to several factors that can compromise stability and control. Uneven surfaces can lead to an unstable base for the stacker, increasing the likelihood of tipping over, especially when lifting heavy loads. The unpredictable terrain may also affect the operator’s ability to maneuver effectively, which can lead to accidents or collisions.

In contrast, flat and dry surfaces provide a stable and secure environment, allowing for smoother operation and reducing the risk of incidents. Concrete surfaces and paved roads, while firm, may also not present as many hazards as bumpy terrain, which significantly heightens the danger associated with stacker use. This is because the constant jolts and shifts on uneven surfaces can lead to erratic behavior of the stacker, potentially resulting in spills or accidents.
