A ladder is a piece of equipment consisting of a series of bars or steps between two upright lengths of wood, metal or rope used for climbing up or down something. They help us move up and down and work at different heights. Portable ladders, in particular, are useful tools because they can be readily moved or carried. They are simply built and come in many sizes, shapes and styles. Key Words: Hydraulic cylinder, Pulley, Microcontroller, Belt, Lock, Battery, Motor. 1. INTRODUCTION 1.1 Different type of mechanism: 1. Hydraulic Scissor ladder: “The machine which is achieved desired height by the using of linkages, folding support in the scissor form is known as scissor mechanism.” A scissor ladder mechanism is a device used to extend or react a platform by hydraulic means. The extension and or displacement motion is achieved by application of force by hydraulic cylinder to one or more support. This forces results is an elongation of the cross pattern. Retraction through hydraulic cylinder is also achieved when lowering of platform is desired. A scissor life table has many useful purposes. The applications of a scissor lift table include a variety of things, but the platform is ultimately designed to help lift and raise heavier objects. The industrial lift is most often seen in behind the scenes of retail establishments and warehouses, although manufacturing engineers are always redesigning the lift for various uses like lifting heavy loads. A hydraulic scissor lift is a mechanical device used for various applications for lifting of the loads to a height or level [1]. A lift table is defined as a scissor lift used to stack, raise or lower, convey and/or transfer material between two or more elevations Fig1. Hydraulic Scissor ladder [1] 2. Automatic Loft / Attic Ladder: An attic ladder (US) or loft ladder (UK) is a retractable ladder that is installed into the floor of an attic and ceiling of the floor below the attic. They are used as an inexpensive and compact alternative to having a stairway that ascends to the attic of a building. They are useful in areas with space constraints that would hinder the installation of a standard staircase. Attic ladders typically consist of a ladder with wider steps and a steep slope. [1] A drawstring will hang down to allow the ladder to be manually extended. Attic ladders are usually made of wood, metal, aluminum. The fire departments carry attic ladders on fire apparatus for use to locate and extinguish fires in attic spaces. They are in a single ladder that is often used by firefighters for interior attic access and have hinged rungs, which allow them to be folded inward so that one beam rests on the other, with the rungs hidden away in the middle[7]. This compatibility allows it to be carried in attic scuttle holes, narrow passageways, and small rooms or closets.
