OSHA 10 Hour Construction Program Practice Test

The primary distinction between hydraulic rough terrain cranes and crawler lattice boom friction cranes lies in the controls related to the boom hoist and the load line. Hydraulic rough terrain cranes utilize hydraulic systems to operate and control the boom and load line, allowing for enhanced maneuverability and flexibility in navigating uneven surfaces commonly found on construction sites. This hydraulic system provides smoother operations and faster response times during lifting tasks.

In contrast, crawler lattice boom friction cranes utilize chains or cables wound around drums for lifting, and their lattice structure offers significant strength and stability. The controls for these cranes, often more complex due to the mechanical nature of the friction system, can impact how the load is lifted and maneuvered.

Understanding these control differences is crucial for operators because it influences the safety, efficiency, and effectiveness of crane operations in various terrains and lifting scenarios. Each type of crane is designed for specific applications, and these control mechanisms play a significant role in their suitability for different jobs.
