Jekko ha presentado la JF545.2, el último modelo de grúa articulada sobre orugas que actualiza la popular JF545. Este nuevo modelo introduce mejoras significativas en términos de rendimiento y facilidad de uso.
La JF545.2 cuenta con una gestión del motor a velocidad variable, optimizando los movimientos de la grúa para hacerlos más rápidos, precisos y suaves, mientras reduce el consumo de combustible. El operador puede elegir entre tres modos de trabajo: Eco, Normal y Power, ofreciendo un equilibrio personalizable entre potencia y consumo. La información operativa, como las RPM del motor y el nivel de combustible, se muestra en una nueva pantalla táctil de 7”, impermeable con clasificación IP66.
La estructura se ha mejorado con estabilizadores hidráulicos rediseñados para una mayor precisión de posicionamiento. Un radiador eléctrico dedicado mantiene el aceite hidráulico a la temperatura óptima, mejorando la fiabilidad y el rendimiento. La grúa también incluye un nuevo filtro DPF para la gestión automática de las emisiones, y para áreas frías, se encuentra disponible un kit de precalentamiento opcional para garantizar la operatividad en cualquier condición climática.
A crane designed to last is the result of careful material selection and meticulous manufacturing processes. To ensure the highest standards of strength and durability, Jekko internally produces all of its structural frameworks using high-strength steel sourced exclusively from Europe.
The production process begins with the longitudinal welding of the boom, carried out by a state-of-the-art automatic system. Components are then joined together using micro-welding seams executed by a team of expert welders. Subsequently, the assembly undergoes welding in one of three robotic plants equipped with advanced joint-finding software. The process concludes at finishing stations where welders complete the final welding and remove any processing residues, preparing the component for the painting phase.
It’s now the time for the welded products to undergo anti-corrosion treatments and final painting by the expert hand of VP Verniciatura, Jekko’s longstanding partner. The process starts with mechanical pretreatment through an automatic sandblasting machine, followed by nanotechnological chemical pretreatment to protect metal surfaces from oxidation. After the pretreatment phases, the booms are ready for the powder coating. The paint is applied with an electrostatic system to minimize product loss and emissions of volatile organic compounds (VOCs). This ensures a complete coverage of every detail with excellent aesthetics. The powders are QUALICOAT Class 2 approved, guaranteeing superior durability and resistance.
The choice of painting system is made during the design phase based on environmental corrosivity category, required durability, and material type.
The collaboration between Jekko and VP Verniciatura is characterized by an integrated approach to quality. Dedicated quality controls occur at the end of each production phase; welding technologies range from visual inspection by technicians to laser instrumentation or other internally designed tools at Jekko. For painting, quality inspections include visual verification, gloss-meter, thickness gauge, impact tester, and Cross Hatch Tester, according to ISO 12944-2 standards. This ensures durability for up to 10 years and resistance to salt spray of 750 hours, achieving a corrosion resistance class of C4h certified by QualiSteelCoat.
This synergy doesn’t only enhance the overall quality of the final product but also represents a joint commitment to innovation and sustainability in production processes. Combining Jekko‘s experience in structural framework production and VP Verniciatura‘s expertise in anti-corrosion treatments and industrial painting demonstrates that collaboration and excellence are essential to achieving outstanding results in the sector. Together, Jekko and VP Verniciatura offer a product that combines structural robustness with high-quality aesthetic finishes, ensuring maximum customer satisfaction.
