Testing was carried out at various locations so as to make sure that the product is functional and achieves the targeted 2. Proposed Design objectives successfully. The above mentioned requirements can be fulfilled by using a compact foldable multipurpose ladder which uses six long and same sized braces (rectangular cross section) with another small channels (square cross section, separated by the required distance) for developing the ladder. There are three different parts in which each part is made of two long braces and six small rungs (perpendicular to braces). All three parts are connected with hinges and door latch type locks, to make the ladder foldable. A plate is attached to each part on one side for a slope. Casters are used in order to make it work like a trolley when required.

Key Words: Ladder, Hinge lock, pin, Braces, Rungs, Slope, Plate, Caster, Frame.

1. Introduction A ladder is a steps consisting of two parallel members connected by rungs; for climbing up or down. It has ascending stages by which the user can climb as well shift heavy loads using the ladder. There are two basic types of ladder, rigid ladder and rope ladder, rigid ladder is the one that can be slandered against a vertical surface such as a wall while rope ladders are the ones that can be hung. The vertical members of a ladder are usually called beams or stiles. Rigid ladders are usually portable, but sometimes they are permanently fixed to buildings.

1.1 Types of ladders 1. Fixed ladder

The computer aided design software Creo-2.0 was used to make the detailed design for analyzing and manufacturing the product.
