LEADING supplier of electrical and mechanical equipment for moving machinery, Powermite, has boosted its cable reeling systems with the introduction of the new SR-Express range from Conductix Wampfler.
Powermite, a Hudaco Group company, holds exclusive Southern African distribution rights for Conductix-Wampfler.
“We understand the paramount importance of product quality for customers and end-users because this is fundamental to product reliability which in turn leads to high machine and plant uptime, productivity and profitability,” said Powermite Managing Director Rolf Lung.
“It is therefore our responsibility to supply products of uncompromising quality that will perform reliably over a long life cycle for lowest total operational and ownership cost. Consequently, we align ourselves only with companies like Conductix-Wampfler, a global designer and manufacturer renowned for its world-class quality, state-of-the-art, customised cable reels for the bulk materials handling industry.”
Combining what Lung describes as the best qualities of the company’s cable reels, the SR-Express range has been engineered to meet the energy and data supply needs of moving machinery that requires energy and data transmission systems including overhead bridge cranes, gantries, mobile tables, aerial ladders and lifts, elevators and elevated work platforms.
The SR-Express is supplied with the cable already installed and connected to the slip rings so that it is ready for use to keep downtime to a minimum.
According to Lung, the halogen-free PUR (polyurethane) cables, specifically designed for reeling applications, provide “excellent wear resistance and high flexibility”. The drum body and flanks of the cable drum are manufactured from zinc-plated steel.
The flank edge has been designed to optimise cable arrangement during winding and to help ensure safety for the user. With winding diameters ranging from 170mm to 400mm, the cable drum is fitted with sealed ball bearings and is lubricated for life.
The USR heat-resistant slip rings are part of a new European range and feature a new design that both facilitates and reduces maintenance. The slip rings are located in an ABS-PC techno-polymere housing outside the cable drum for optimal access to connection. This impact-resistant slip ring housing is protected from dust and moisture ingress and is equipped with captive screws and a breather to prevent condensation.
Arranged in series or parallel, the springs are manufactured from high-performance textured steel and are lubricated with corrosion-resistant grease and individually encapsulated in a cassette. The patented spring cassette ensures safe and easy manipulation including replacement or reversal of winding direction.
The mounting flange, manufactured from cast aluminium alloy or cast iron, has been specially designed for quick, easy and safe installation of the reel on the spring reel shaft.
Customers and end-users have a choice of three bracket options – fixed bracket, fixed bracket and roller guide arm (available on all models) as well as fixed bracket and roller guide arm and swivel bracket (for SR10 to SR50 models).
With an IP65 rating, the SR-Express range is suitable for both indoor and outdoor applications, performing optimally in stringent conditions and an ambient temperature range of -20°C up to +60°C for the standard E0 environmental specification and as low as -40°C for the E1 specification. An E3 option for severe conditions will be introduced at a later stage. The spring cable reels are protected against dust and water ingress and are able to withstand an impact of 20 joules.
