Crates, tongs and spoons for handling bulk and waste. This is what Stemm has been designing and manufacturing for sectors such as steel, maritime, cement and the environment at its facilities in Hernani since 1984. Almost 40 years of activity have brought it one of the world leaders in the sector. this. And its products can be found in countries such as the United States, India, Australia, South Africa, France, Colombia, Argentina and Saudi Arabia, among others.
With work for leading companies in the industry, such as Liebherr, Arcelor Mittal, CAF, Verlinde, ABUS or GH Cranes & Components, among others, the company from Hernani (Gipuzkoa) carries out the comprehensive design and manufacture of all its equipment. , from boilermaking, machining, assembly and manufacturing of oleohydraulic equipment. Equipment and components that always combine three important concepts, says Martin Amesti Aramburu, general director of Stemm: “Our products always combine structural strength, electrical and hydraulic power for efficient handling and minimal maintenance.”
To achieve this, the company is strongly committed to R&D&I, “a fundamental element of Stemm,” says Amesti. “Thanks to our engineering and R&D&I services, we have developed advanced technological projects with the aim of responding to the many needs of different sectors, which are increasingly changing,” emphasized Amesti.
From this commitment, for example, the ‘KIDNEY’ self-filtering system was born. “This is a new system integrated with garbage grabs and buckets for cement and clinker. It does not require maintenance and is automatically debugged while the engine is running, without the need for any ” explained the general director.
Another improvement is a system that automatically adjusts the operating speed depending on the conditions of the material to be handled, “which is especially valuable in the steel industry,” said the general director of Stemm. “The combination of hydraulic and electrical energy allows work cycles to be increased by 50%, reducing the daily cost of electrical energy,” he added.
Digitalization and new products
Digitalization is added to R&D&I with the GRAB CONNECT system, which allows remote control of octopuses, spoons and tongs anywhere in the world. This system provides important technical data such as pressures, temperatures, current consumption, number of maneuvers performed, etc., in addition to conducting diagnostic and preventive maintenance treatments. “Thanks to all this information, the client will be able to build all the corrective or update operations, so that when the operations start, everything is fully controlled and there are no possibilities of unexpected events,” details American.
Recently, Stemm expanded its already extensive product catalog with the launch of electrohydraulic grabs designed for the cement industry. “This is a sector that requires strong performance and characteristics to face the harshest environmental conditions of abrasion, wear, vibration and high temperatures,” explains Amesti. “Therefore, with this new proposal we aim to cover the needs encountered by our clients.”
