Offering cranes, services and systems to the container-handling industry, engineering company Paceco España (Spain) must adjust to its customers’ needs. As ships get bigger, quay and yard cranes must increase height and reach, while also becoming more efficient. Today, Paceco España can load and offload ships from 25 container lines. The company currently produces one of the largest and most efficient cranes on the market, the Portainer Malaccamax, which maximally offers a 72.5-metre outreach, a 52.5-metre clearance under spreader, and a 30.48-metre rail span.

Paceco España first connected with Nord-Lock in 2009, when there was a problem with one of the company’s quay cranes. The crane, with a 65-ton load capacity, had problems with the fixing of the gantry reducers – the gearboxes that move the quay crane along the dock. During operation, the fixing screws vibrated loose.

During their problem analyses, Paceco España’s engineers connected with Nord-Lock and when it presented a solution, Paceco España was pleasantly surprised. “We have been using their washers since 2009, and haven’t had any problems with bolted connections being subject to vibrations since then,” says engineer Pelayo Bobes. “With Nord-Lock washers, we have been able to provide total customer satisfaction and in turn saved both money and time.”
