“Ice Chain” Reduces Freeze Induced Downtime

“Ice Chain” Reduces Freeze Induced Downtime

In order to prevent freezing of the energy supply, such as on inclined lifts, igus has developed a new e-chain called the “ice-chain”. With injection-moulded raised contact points, the chance of freezing is significantly reduced along with the costs of downtime and maintenance.

Inclined lifts are used in a variety of places to transport people or goods. However, regardless of its purpose, inclined lifts always require long-lasting, trouble-free operational systems. A failure would usually cause high maintenance costs due to the its height and limited accessibility. These challenges are compounded when inclined lifts are used in adverse weather conditions, such as in passenger lifts in the mountains or in construction lifts outdoors. This is because in these scenarios, operations can only be continued after a complicated process of defrosting. Thus, concepts that prevent freezing of energy chains are needed to guarantee safety and reliability under these extreme conditions.

New Design Prevents Plant Failure

There is a risk of freezing especially in systems with energy chains that are rarely moved and igus’ freeze-resistant ice-chain is best suited for such purposes. The technology powering these chains are as simple as it is effective: two raised domes per chain link are injection-moulded onto the crossbars of the e-chain along the outer radius of the chain. As a result, the contact surface area, and thus the risk of freezing, is significantly reduced. The e-chain is still safe in the guide, but it touches with only a tiny surface area and does not stick. The domes applied on the crossbars by injection moulding optimise the climate behaviour of the ice-chain without diminishing the traditionally high strength of the e-chains. The rectangular stop-dog system, which distributes the forces evenly, and the strong pin/bore connection in the side links guarantee high strength, offering large payloads or fill weights. Since the domes have only a height of 1.8 millimetres, the installation height is only slightly larger. The ice-chain can therefore be easily integrated even in confined installation spaces.

Withstand Freezing Temperatures With e-chains And Chainflex Cables

Like all e-chains for outdoor use, the ice-chain is made of weatherproof and media-resistant high-performance plastics. The material igumid G can be used in applications down to -40°C. Together with chainflex cables optimised for continuous dynamic use in energy chains, the ice-chain reliably moves applications even in snow and ice. With jacket materials made of PUR or TPE, chainflex cables provide trouble-free service even at temperatures well below freezing over a very long period of time. And if temperatures down to -35°C should actually occur, a chainflex CF29 series servo cable will still reliably supply any drive system. As part of the igus ready-chain concept, the ice-chain is also available as a complete system fully equipped with pre-harnessed cables that can be quickly installed and connected.

Merchandise Management 4.0: Electronic igus Cable Catalogue With BMEcat

Digital catalogue data now provided for chainflex cables

Selection, procurement, ordering, invoicing – complex merchandise management with products in the B2B area needs one thing above all: simple and standardised processes from the manufacturer to the recipient, and uniform worldwide. Under the name BMEcat, the Federal Association for Supply Chain Management, Procurement and Logistics (Bundesverband Materialwirtschaft und Einkauf (BME)) has developed a standard system for the electronic exchange of catalogue data that can easily be integrated into existing merchandise management systems. igus, the motion plastics specialist, is now using the exchange format for catalogue data for its chainflex cables used in moving applications.

igus: CF27.D Chainflex Cables

The CF27.D Chainflex cable series by igus have a minimum bend radius of 7.5 times the cable diametre, and are suitable for use in small installation spaces and  dynamic applications, for example in gantries.

These servo cables combine a braided structure with and gusset-filling extruded TPE inner jackets, which provides stability for the braiding and to guide the braided shield during constant movement. The series also features an abrasion-resistant halogen-free, flame-retardant PUR outer jacket and is available in 28 different types.
