Lifting technology

The lifting equipment includes all technical measures taken by the vertical load movement, both in the assembly technology and in materials handling .

Basics

By raising or lifting refers to an increase in the amount or level than by an external force caused movement of a body to the top, such as the lifting of a load by a crane , a hoist or other machines. The energy to be expended is mainly due to the force of gravity and is proportional to the mass and the difference in height. In addition, there is a small amount of friction , which can only be zero during processes in free space .

Methods

The basic principles of lifting technology are:

• the lever
• the wedge
• the pulley
• the pressure difference (hydraulic lifting technology)
• the threaded spindle

Examples

Modern industrial rope hoist on overhead traveling crane

• Elevator
• Lifting boom
