PC-controlled 3-axis motion platform adds further realism to training experience
A three-axis motion platform based on Baldor Electric Company's Ethernet-compatible drives is helping to further increase the realism of crane training experience by physically moving a simulator system's replica operator cabin in synchronism with computer-generated images. The specialist machine manufacturer Electropneumatics & Hydraulics developed the motion platform for the leading training solutions and services supplier Applied Research International (ARI).

Based in New Delhi, India, ARI produces a comprehensive range of simulators for marine and allied applications. Its products include a wide variety of offshore, quay-side and gantry crane simulators to provide safe, cost-effective operational training for container movement and bulk handling operations. ARI's simulators emulate the visual, behavioural and operational characteristics of their real-world counterparts to create a fully immersive environment in which the trainee can gain true hands-on experience. A typical crane simulator comprises a modular PC-based control system, a replica operator cabin and seat, a high fidelity audio-visual system, and an instructor station equipped with CCTV for monitoring the actions of the trainee.

Bombardier Transportation has its global headquarters in Berlin, Germany with a presence in over 60 countries. It has an installed base of over 100,000 vehicles worldwide. The Group offers the broadest product portfolio and is recognized as the leader in the global rail sector.

Within the UK Bombardier has established a world class engineering maintenance and repair site based at Crewe, the historic railway engineering town established by the Midland Railway in 1839.

Introduction:
Gone are the days when a MegOhm meter and a digital multi-meter were the main tools in electrical maintenance.  Advances in technology now offer engineering professionals both off-line and on-line (real time) instruments to verify the health of rotating machinery.  

Modern on-line technologies permit assessment of the ‘whole motor system’, which is comprised of three components:  power, motor & load.  By focusing on these three components, troubleshooting now becomes truly predictive!

Air Bearings Ltd (ABL) of Poole, Dorset, are Queen’s Award winners for Export and Innovation in the design and manufacture of high speed air bearing spindle motors. Their use of the Whitelegg Baker AWA 2.2 analyser enables rapid testing of each motor ensuring total quality control.

Non contact bearing systems offer significant advantages over other low friction devices. In an air bearing the surfaces in motion are separated by a thin film of pressurised air acting under the laws of physics.
