Which of the following is NOT a maintenance task on ground ladders?

In the context of maintaining ground ladders, it is essential to focus on components directly involved in the ladder's operation and safety. The tasks that involve cleaning and lubricating the dogs, slides, and hooks are crucial for ensuring that these parts function properly and that the ladder can be deployed and secured effectively.

Dogs, which are the locking mechanisms that secure the rungs when the ladder is extended, need to be cleaned and lubricated to ensure that they release and engage correctly. Similarly, the slides, which allow the ladder to extend and retract smoothly, also require regular maintenance to prevent corrosion and ensure proper operation. Hooks, which can be used to secure the ladder in place, need to be maintained to ensure they can latch securely and withstand the forces applied during use.

On the other hand, halyards, which are the ropes used to raise and lower the fly sections of extension ladders, do not typically require lubrication as part of routine maintenance. Their primary care usually involves checking for fraying or damage and ensuring they can still perform their function effectively. This is why the maintenance of halyards does not encompass the same type of cleaning and lubrication tasks as the other components of the ladders.
