Differences between a crane and a lifting aid:
Cranes and lifting aids are both devices used for lifting and moving, but there are significant differences in their structure, purpose and way of working. This article looks at what these two devices are and how they differ from each other.
Crane
A crane is a device designed to lift and move heavy loads vertically and horizontally. Cranes are widely used in the construction, logistics and industrial sectors. They can be stationary or mobile and often have a large lifting capacity.
Cranes come in many types: for example jib cranes, overhead cranes and gantry cranes. What they all have in common is that they can lift heavy loads and move them within a certain area.
According to the Finnish regulations, a crane must also lift more than 500 kg to be classified as a crane. Smaller ones always fall into the lifting aid category, although their use, servicing and inspection are the same as for a crane under the regulations.
Cranes are further divided into categories such as industrial cranes, lifting jacks and loader cranes.
Purpose:
Cranes are mainly used for larger lifts, such as on construction sites, in ports, industrial plants and warehouses, where great lifting capacity and mobility are needed.
Lifting aids
A lifting aid, on the other hand, is a device that makes lifting a load easier, but it is not an independent device like a crane and therefore often needs another machine to do the actual lifting. Lifting aids are usually smaller and lighter, and their use focuses on supporting individual loads or work stages.
Lifting aids include, among others:
- Lifting slings and chains: Used to lift and move the load, but they are not independent devices and require a separate crane or other equipment.
- Grabs: For example beam clamps and lifting tongs
- Turning devices: used to lift a load into the air and rotate it around an axis.
Purpose:
Lifting aids are mainly used for smaller and lighter lifting tasks or to assist lifts of all sizes. They can be accessories for cranes or support individual lifting situations. In construction projects, for example, lifting aids are used when lifting small building materials or moving goods in storage areas.
Summary
Although both cranes and lifting aids serve the same purpose, i.e. lifting loads, their differences show in their structure and purpose. A crane is a large, often independently moving device designed to lift large loads even without additional parts and devices. Lifting aids, on the other hand, are smaller and more limited devices that support lifting tasks and can be accessories for cranes or other equipment.
The choice between a crane and a lifting aid depends on the size and requirements of the task.
