Automatic monitoring of mobile harbour equipment
The increasing globalisation of the world economy is pressurising ports, docks and harbours into handling ever-increasing volumes of cargo, so mobile harbour equipment has to work efficiently and reliably at all times. Tony Ingham of Sensor Technology Ltd explains how monitoring the work rate of cranes, loaders and unloaders means their performance can be optimised and downtime for maintenance can be scheduled for minimum disruption to operational requirements.
How to specify simple, reliable and adaptable screw jacks
The need to raise a load is one of the most common requirements in industry. This is often achieved with a screw jack, but these need to be used in conjunction with other drive components and possibly in a system of several synchronised screw jacks. Ian Carr of Drive Lines Technologies explains how lifting systems are typically designed.
The death of proprietary networks
Like it or not, we live in modern world of fluidity and interconnectedness in which the once ordinary now transcends all previous boundaries. Take the humble kettle for instance. It’s a sign of the times that you can now purchase a kettle you can control from your phone via the internet. It will even send you notifications when it needs filling or if it’s at optimum temperature. Because it was hard to tell before. Joking aside, one place where interconnectivity really is making a difference is on the factory floor. Here Jonathan Wilkins, marketing director of EU Automation, takes a look at one of the casualties of fluid communication in the factory. That is, the death of proprietary networks and communication protocols in favour of the uninhibited free flow of data.
Soft starter or variable speed drive for your motor?
Motor starting can induce shock loads into the driven equipment and harmonic disturbances into the main supply. Jerry Hodek of Exico Electric Motors says both variable speed drives and soft starters will help reduce this effect and explains which option best suits an application.
Water-cooling for power supplies: the benefits
Using water-cooling for electrical devices has always a stigma due to the combination of liquid and electricity. Here, Steve Hughes, managing director of REO UK, investigates the benefits of this technology
How to select the right shaft coupling for a rotary encoder
This article from Abssac offers some useful tips and advice for selecting the correct type of shaft coupling for rotary encoder applications.
Ten things you need to know about machine guarding standards
This article presents ten things that machine designers and specifiers should know about machine guarding standards, and the information will also be useful for production managers, health and safety managers, health and safety representatives and others with an interest in machinery safety.
Motors: the tip of the iceberg for drivetrain efficiency?
Fuelled by the introduction of more stringent IE efficiency classes, manufacturers are chasing headline efficiency figures which could only have been dreamed of just 10 years ago. There’s no denying that this is a positive thing for industry, but is motor efficiency just the tip of the iceberg?
