In the four-wheel crab mode, how do the front and rear wheels turn?

In four-wheel crab mode, both the front and rear wheels of the crane turn in the same direction. This coordinated movement is designed to allow the crane to move diagonally across the worksite while maintaining stability and maneuverability. When both sets of wheels turn together, it provides enhanced control and promotes smooth, agile movements, which is particularly beneficial in tight spaces or when navigating around obstacles.

This approach is fundamentally different from other steering modes, where wheels may turn in opposite directions or have a more constrained movement pattern. Understanding the mechanics of how four-wheel crab mode operates helps crane operators navigate safely and effectively, ensuring they can execute complex maneuvers required on various job sites.
