Treotham presents world’s first driven e-chain system for long travels
High dynamics and long service life: the igus drive-chain is the world’s first powered e-chain system for long travels (1,000 metres and more). It works on more than 1,000 metres: igus drive-chain impresses with maximum dynamics and long service life, while saving up to six tons of weight Almost no limits on long travels, high dynamics, long running times – these are the characteristics that distinguish the innovative igus drive-chain. The world’s first energy chain with its own drive ensures significantly longer running times on extremely long travels because hardly any push/pull forces act on it. Across the globe, rail-mounted automated stacking cranes (ASCs) in ports are just one of the applications that benefit. 40 years ago, container ships were tiny compared to today’s vessels. They held an average of 1,000 containers. Today, giants in the Triple-E class carry almost 24,000 containers – and that number is rising. These sizes pose challenges for ports, which must continuously expand their infrastructure, including the ASCs that load containers onto lorries and trains. e-chains use their own drive to follow ASC movement The drive-chain design concept works as follows: drive boards are mounted on the outer radius and drive the e-chain in the lower run. The bottom rail has motor-driven friction wheels on the sides and rollers on the top. When the crane sets off, the friction wheels also start their motors. The lower run travels along the rail in a synchronised movement, during which hardly any push/pull forces from the moving end act on the chain links. e-chains with drives are an alternative to steel cable drums Self-powered energy supply systems are an economical alternative to traditional systems that have been used in ASCs for decades: steel cable drums that wind and unwind motor cables – often in two directions when the […]
