  2. Lift table - Wikipedia

    en.wikipedia.org/wiki/Lift_table

    A scissor lift. A lift table is a device that employs a scissors mechanism [ 1] to raise or lower goods and/or persons. Typically lift tables are used to raise large, heavy loads through relatively small distances. Common applications include pallet handling, vehicle loading and work positioning. Lift tables are a recommended way to help reduce ...

  3. Scissors mechanism - Wikipedia

    en.wikipedia.org/wiki/Scissors_mechanism

    The scissor mechanism is a mechanical linkage system used to create vertical motion or extension. It consists of a series of interconnected, folding supports that resemble the shape of a pair of scissors, hence its name. The scissor mechanism is widely employed in various applications, including scissor lifts, folding tables, adjustable height ...

  4. Four-bar linkage - Wikipedia

    en.wikipedia.org/wiki/Four-bar_linkage

    Four-bar linkage. In the study of mechanisms, a four-bar linkage, also called a four-bar, is the simplest closed- chain movable linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar ...

  5. Slider-crank linkage - Wikipedia

    en.wikipedia.org/wiki/Slider-crank_linkage

    A slider-crank linkage is a four-link mechanism with three revolute joints and one prismatic (sliding) joint. [1] The rotation of the crank drives the linear movement of the slider, or the expansion of gases against a sliding piston in a cylinder can drive the rotation of the crank. There are two types of slider-cranks: in-line and offset.

  6. Hoist (device) - Wikipedia

    en.wikipedia.org/wiki/Hoist_(device)

    A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. The most familiar form is an elevator, the car of which is raised and lowered by a hoist mechanism.

  7. Linkage (mechanical) - Wikipedia

    en.wikipedia.org/wiki/Linkage_(mechanical)

    A mechanical linkage is an assembly of systems connected so as to manage forces and movement. The movement of a body, or link, is studied using geometry so the link is considered to be rigid. [1] The connections between links are modeled as providing ideal movement, pure rotation or sliding for example, and are called joints.
