løftearm

A løftearm, often translated as lifting arm or hoist arm, is a mechanical device used to raise, lower, or move heavy objects. It typically consists of a strong, rigid beam or lever that pivots from a fixed point, allowing for mechanical advantage. The design can vary significantly depending on the application, from simple levers used in manual lifting to complex hydraulic or electric systems found in industrial settings.

The principle behind a løftearm is leverage. By applying force at a distance from the pivot point (fulcrum), a greater force can be exerted on the load at the other end. This allows a person or a machine to lift objects that would otherwise be too heavy to move. Common examples include forklifts, cranes, and even some types of medical equipment designed to assist with patient transfers.

Løftearms are crucial in various industries, including construction, manufacturing, logistics, and healthcare. They enhance efficiency, reduce the risk of injury, and enable tasks that would be impossible without mechanical assistance. The materials used in their construction, such as steel or aluminum, are chosen for their strength and durability to withstand significant loads. Safety features are also paramount in løftearm design, often including locking mechanisms, overload protection, and emergency stop systems.
