PORT CRANES SPARES
e-chainsystems for Cranes: Reduced cost. Increase expected service life. Have been tried and tested. Dear customers, We would like to introduce you to the high-tech products of IGUS for your particular branch of industry. IGUS energy chain systems are a highly effective alternative to conductor rails, festoon systems and motor cable drums. IGUS e-chainsystems and chainflex flexible cables are in use worldwide in more than 10,000 port-facility applications: Ship-to-shore cranes, bulkcargo handling cranes, RTGs, RMGs, Goliath cranes, spreaders, reach stackers etc. The main advantages for crane builders and operators are:
● Space-saving design
● No additional drives are necessary
● No control system is necessary
● All media can be transported: energy, data, air, water etc.
● Easy maintenance lowers your downtime
● Wind and weather resistant
● Synchronous run of trolley and energy chain system
● Easy and fast installation of additional cables
● Spare part guarantee for ten years and more
Generally, slewing bearings are large-size rolling bearings that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction. They can perform both slewing (oscillating) movements as well as rotational movements.
Basically, a slewing bearing consists of an inner ring (a), an outer ring (b) and rolling elements − balls (c) or cylindrical rollers − that are separated by polyamide spacers (d). The rings, one of which usually incorporates a gear (e), are provided with holes (f) to accommodate attachment bolts. The holes may be threaded. Generally, only the raceways in the rings (h) are hardened and precision-ground. Integral seals (g) made of acrylonitrile-butadiene rubber (NBR) keep the lubricant in, and contaminants out of the bearing. Slewing bearings are relubricated Slewing bearings through grease fittings (i) to reduce maintenance and operating costs.
Compared to traditional pivot arrangements, slewing bearing arrangements provide many design and performance advantages. The compactness and large inner diameter simplify the design of the bearing arrangement and its associated components. The low sectional height of these bearings means that the pinion lever can be kept short. In most cases only flat surfaces on the associated components are needed. Slewing bearings were originally designed to be mounted only on horizontal support structures, but can now be used successfully in vertical bearing arrangements.
Slewing bearings perform extremely well in a variety of applications such as: • access platforms • bucket wheel excavators • conveyor booms • cranes of all types • small, medium and large excavators • indexing tables • ladle turrets • offshore applications • robots • railway bogies • rotary platforms • stackers • solar mirrors • tunnel boring machines • wind turbines
Cable Guiding System
There are many options to supply your equipment and systems with energy and data. But there is hardly a solution as universal and durable as the e-chain system. Whether you have a circular motion, a suspended or upright application, a long travel distance, high loads or large cables and hoses -igus plastic e-chains will help you solve nearly and type of energy supply problem, quickly, safely and within ease. Whether you wish to reliably guide many large hoses for any type of media, sensitive fiber optic signals over long distances, disruption-free data in torsional movements, or only air at high accelerations, igus can supply you with the matching energy supply system in addition to the optimally matched chainfle cables.
By tapping into the extensive igus, construction kit, you will find the solution to match your needs and application: from the individual components to the completed installation at your facility. We have developed a online tool to help you find these resources with greater ease.
