Modification and modernisation

In the production processes we find many cranes, which were built at very high quality, but due to the old age issues begin to appear .

Problems can be in the reliability of operation or in the performance of the work process. With the redesign or modernization, we can achieve that the old crane is brought back to a level that will ensure reliable and efficient performance of its function in the work process.

1. Modifications

Many cranes in use perform their function well, but problems begin to appear on a certain component.

Also, the shortcomings of the crane can occur due to changes in the production process. Problems can often be solved with a minor intervention on the crane, where only the problematic component is modified.

The most common alterations are:

Replacement of lifting brakes and clutches with more modern ones

Drive modification

Upgrading with magnetic or mechanical grippers

Installation of guiding wheels

Installation of an overload or weighing device

2. Modernizations

Many cranes have been in use for 50 years or more. Despite the fact that this number sounds high, many manufacturers at that time produced very massive and high-quality cranes, which still perform their function well and will continue to do so in the future.

.Especially with the use of frequency inverters, the usability of the crane is greatly increased, and due to lower shocks, the service life of mechanical components is increased. Switches and sensors are also available today, which can greatly increase safety.

It makes sense to renovate such cranes, because for only a fraction of the price of a new process crane, we get an crane that will perform its tasks efficiently for another 20 or 30 years.

The scope of modernization depends on the characteristics of the crane and the needs of the client, but it mostly includes:

Making a new electrical project

Production of new electrical cabinets with frequency inverters

Replacement of cables, switches, control panels, lighting, radio controls, ...

Installation of an anti-collision system

Renovation of the cabin interior

Conversion of the central drive of the bridge to two separate direct drives

Brake and clutch replacement


Certified test by an authorized person to inspect the cranes
