Energy chains are used to carry and guide power, data and signals to moving parts of machines or structures, while in motion. They aim to ensure the seamless operation of cranes, milling and boring machines as well as other mobile equipment through the protection of cable, hose and hydraulic supply at a fixed or variable speed.

Electrical and mechanical equipment and energy supply systems specialist, Powermite, stresses that its experience in drag chain applications with German energy chain manufacturer EKD, positions it as a specialist supplier of EKD Kolibri energy chain to Southern African industries.

The EKD energy chain aims to reduce operational costs and extend component life. It is widely used across a range of industries such as ports and harbours, materials handling, as well as industrial and water treatment plants.

Three different types of energy chain are available:

• A one-part link or flap-open link range
• A range of bending radii, to facilitate large cables
• A chain with separate end-connectors, in which each link can be used as an end-connector.

The EKD Kolibri series ranges from external sizes of 15 mm x 15 mm through to 65 mm x 225 mm and the EKD PKK range, which can handle external sizes up to 100 mm x 340 mm, is also on offer. Steel external sizes start from 50 mm high x up to 1500 mm wide.

Available in galvanised steel, stainless steel and carburised, or hardened, steel, the company asserts that its range of EKD Kolibri energy chain is reliable, robust, requires minimal maintenance and spares, and can operate in extreme temperatures of between -20 °C and 100 °C.

Powermite’s energy chain portfolio also includes a plastic range consisting of self-extinguishing, ATEX, anti-static, steel-coated and robotic bi-directional chain. All plastic chains are equipped with integrated connectors and therefore require few spare parts, which helps to reduce costs and potential downtime. The company also offers chains engineered for ultralong distances. These chains, known as the Marathon System, use roller sets and are capable of maintaining speeds of up to 200 m a minute.

The company’s countrywide branch and distribution network carries a variety of spares for the EKD Kolibri energy chain range and delivers after-sales service to end-users across 15 African countries.
