Altex Engineering Ltd, based in Calne, is a specialist in precision engineering and sheet metal fabrications. With over 40 years of experience, Altex delivers design, machining, and fabrication services to customers across multiple sectors, combining expert craftsmanship with state-of-the-art technology.
Granada Cranes was commissioned to design, manufacture, and install a new 6,000kg single girder overhead travelling crane at Altex’s facility. The project aimed to replace older lifting equipment with a modern, reliable, and efficient solution that could support precision engineering operations in a clean indoor environment.
The Results
The new 6-tonne single girder crane provides Altex with a robust, efficient, and future-proof lifting solution. Thanks to frequency inverter drives, load handling is now smoother and safer, minimising wear on mechanical components and extending the lifespan of the crane. The addition of condition monitoring gives operators greater visibility over performance and potential issues, supporting a proactive approach to maintenance.
For a precision engineering company like Altex, reliable lifting is essential to maintaining production efficiency and meeting strict quality standards. This installation shows how Granada Cranes combines engineering expertise, trusted SWF components, and modern safety systems to deliver solutions tailored to each client’s environment and lifting needs.
