A ladder is a tool used to gain access to higher levels, heights, or elevated surfaces.
It typically consists of two vertical supports (rails) and a series of horizontal steps or rungs that allow users to climb up and down.
Ladders are used in various settings, such as construction sites, homes, and outdoor environments, and come in several designs depending on their specific purpose.
Common types of ladders include:
1. **Step Ladder**:
A self-supporting ladder with a hinged design that opens into a triangular shape.
It is commonly used for indoor tasks like reaching high shelves or light fixtures.
2. **Extension Ladder**:
A long, non-self-supporting ladder that can be extended in length by sliding sections.
These are ideal for tasks such as reaching roofs, windows, or high ceilings.
3. **Folding Ladder**:
A compact and versatile ladder that can be folded into different shapes, including an A-frame or straight ladder, for various uses.
4. **Multi-Position Ladder**:
A ladder that can be adjusted into multiple configurations, offering flexibility for different tasks.
It can be used as a step ladder, extension ladder, or scaffolding.
5. **Platform Ladder**:
A type of ladder with a wide, stable platform at the top, used for extended work at height, often found in industrial settings.
Ladders are made from various materials, including wood, aluminum, fiberglass, and steel. The choice of material depends on factors like weight, strength, durability, and whether the ladder needs to be non-conductive (for electrical work).
Safety is crucial when using ladders, and it is important to follow guidelines like ensuring the ladder is placed on stable ground, not standing on the top rungs, and maintaining proper balance.
