A cantilever crane is a special type of crane used primarily in industrial settings to lift and move loads. Unlike other crane systems, the cantilever crane is mounted on a wall or vertical beam and has a boom arm that extends horizontally. This arm can be designed to be either fixed or pivoting to allow for greater flexibility in the work area.
Basic Functionality
The basic functionality of a console crane is based on the lever principle. The boom arm, also called the console, acts as a lever, at the end of which a lifting device (such as a hook or a gripper) is attached. This lifting device can be moved back and forth along the boom to position and transport loads. Depending on the model, the boom arm can also be rotatable, which offers additional freedom of movement.
Console cranes are usually equipped with an electric drive that allows the lifting and lowering of loads as well as horizontal movement of the hoist. However, manual console cranes, in which the loads are moved by human power, are also available and are used in less stressful applications.

Types of Console Cranes
Console cranes come in various designs and models, each tailored to specific requirements and areas of application. This variety makes it possible to find the right solution for almost every industrial application. The most common types of console cranes include wall-mounted console cranes and column-mounted console cranes, which are characterized by their different design features and possible uses.
Wall Bracket Cranes
Wall bracket cranes are mounted on a fixed structure such as a building wall or a supporting pillar. They consist of a horizontal boom arm that is attached to the wall and a hoist that can be moved along the boom.
Features of wall bracket cranes
- Space-saving: Because they are mounted on walls, wall bracket cranes do not require floor space, maximizing the usable area in the work area.
- Easy installation: Installation on existing structures is comparatively easy and does not require any complex foundation work.
- Limited swing range: The swing range of a wall bracket crane is limited by its mounting on the wall, making it ideal for applications where only a limited work area needs to be covered.
Pillar Bracket Cranes
Pillar-mounted cranes are free-standing cranes that are mounted on a base plate and have a vertical column as a support structure. The horizontal boom arm is attached to this column and can rotate around the column.
Features of pillar bracket cranes
- Free placement: Since they are not attached to walls or other structures, column bracket cranes can be placed freely in the room, offering maximum flexibility.
- Large swivel range: The boom arm can often swivel up to 360 degrees around the column, covering a large working area and offering versatile application possibilities.
- Robust construction: The freestanding design requires a stable and robust construction, which makes pillar bracket cranes particularly suitable for heavy loads and intensive applications.
