Which of the following is a ladder type?

• A. Rope ladder
• B. A-frame ladder
• C. Platform ladder
• D. Pole ladder

Answer: (D)

Pole ladders are designed specifically for climbing utility poles. They attach to the pole and provide rung-like steps that stay aligned with the vertical structure, offering a secure, stable climb as you move up or down the pole. Rope ladders lack the rigid, fixed configuration needed for climbing a pole safely, making them unsuitable in this context. A-frame ladders are self-supporting and sit on the ground, not attached to a pole, while platform ladders are tall, ground-based ladders with a standing platform at the top for working. So, the ladder type intended for pole work is the pole ladder.
