One of the biggest challenges we have faced in recent years has been to plan the succession of the workshop manager of Transgrúas, who will be working in the company for 39 years


With the aim of continuing to provide the high level of technical service in the assembly of cranes and other equipment that we commercialize, and for which we have a reputation in the market, for some years now we have been facing the situation of ensuring a continuity in quality of the service we offer from the workshop, for which it was essential to have the involvement of Enrique Jimenez, head of the Transgrúas workshop since 1980 and of the person who has been occupying the position, Rafa Molina. In this post we share the conversation with them about how this period of "transfer" of experience and technical knowledge of the cranes has been and the approach on the way to face a montage from Enrique's point of view and the fresh vision of Rafa , a young person who takes over with a different training and knowledge and with a technology of machines and vehicles totally different than they were 40 years ago.

There have been several challenges for all: on the one hand, the evolution in the design and operation of the cranes, which have evolved from a purely hydraulic operation, to incorporate more and more electronic elements, until reaching the current digital era, with digital safety and control devices on both cranes and vehicles. On the other hand, regulations to legalize vehicles have also been changing over the years. And all these elements directly influence the way the crane is mounted on the truck.

Therefore, since the founding of Transgrúas in 1978, the assembly work has changed radically. From Enrique's point of view the assemblies, initially were easier made: "to start with, the cranes were of smaller tonnage and reach. Over time, I remember that Fassi every 2-3 years was renewing the cranes and with the technical department of Fassi we were updated to update the assemblies. What most prevailed the entire part of the hydraulic circuit. Then the cranes were sophisticated with the incorporation of limiters to improve safety in the use of cranes. First were hydraulic and mechanical limiters and from 1995 gave way to all the electronics applied to the machines: limiters of reach in the crane and also in stabilizers. This evolution was also marked by the transformation of the demand of customers who increasingly requested cranes with greater reach and accessories attached to the crane, such as jibs, baskets, winches. All this has been achieved by applying a lot of technology to the cranes which implies more complication in the assembly ".

And from Rafa's experience, the reality of the mounting nowadays is that "they have taken an important turn with respect to the old ones, with the incorporation of FSC (stability control) to the limiters, which on one hand offer greater safety to the operator with total control of the equipment but forces us to manufacture a completely stable assembly to obtain the maximum performance offered by the crane.

To the great experience acquired in all these years, we have added new methods that help the whole machine to be totally stable even without extracting 100% the stabilizers, for this we have learned tecniques used by Nordic countries that are giving a very positive result, including new materials with greater resistance that support a high percentage of the working fatigue of the crane, leaving to the chassis of the vehicle a very low percentage.

The new limiters incorporate more and more, improved canbus sensors that help improve working conditions and thus customize each client for their different jobs. We have also incorporated into our workshops new machinery such as oxyfuel, which helps us to improve and speed up our production. At a technical level we are also working daily with greater training and dedication in all our brands to get the most out of them and obtaining very satisfactory results".

As for us,  we can only thank both of them for their dedication and collaboration to continue guaranteeing the highest level of quality and safety in the assemblies that we make of all our equipment.
