I've been injured on the railroad
Machine Design's safety expert, Lanny Berke, examines an accident
that injured a railroad worker. Turns out a squeaky wheel didn't get the
grease.

Navy tests rail gun
The U.S. Navy is testing a weapon that could be put on ships in the
next decade, a 10-MJ rail gun that can send projectiles travelling over
2,500 m/sec towards their target.

Keep the trains running (game)
Take a break and see if you can keep the trains loaded and running
on time. Maybe order a pizza and pretend you're Mussolini.

Disc-brake calipers
The spring-applied, hydraulically released VKSD Model disc-brake
calipers are used for emergency stops, for normal stopping and parking,
at junctions where one conveyor feeds material to another (at risk of
overspill), or where there is risk of personal injury, particularly in
underground mining.
The brakes may be fitted to the tail drum, driving drum, or motor shaft.
For long overland conveyors, the VKSD should be fitted to the upstream
end to prevent a catapult effect due to the reversal of belt tension.
These brakes are suitable for winder and haulage applications.

High-precision miniature shaft
coupling
The MK1 bellows couplings allow for increased bore diameter within a
given coupling size through the use of radial setscrews with unique
dismounting grooves. The coupling helps adapt between shafts with a
large difference in size. The coupling’s stainless-steel bellow
compensates for axial, lateral, and angular shaft misalignments
simultaneously, while operating with zero backlash and high torsion
resistance.
Available torque ranges are 0.05 to 10 lb-in. and bore sizes from 1 to
28 mm.

The Energy Efficiency Web Conference & Expo
Engineers saw and heard great educational content at the Energy
Efficiency Web Conference and Expo. If you missed the live virtual
event, don’t despair! An archive of the full day’s agenda is now
available.
Design engineers are required to integrate energy efficiency into their
designs while maintaining lower costs, the highest reliability or both.
The editors of Machine Design understand these challenges
and have developed this conference to help engineers understand the
recently imposed energy mandates. The information presented at this
educational event will help engineers compare the different technologies
and product related to energy efficiency. Attendees will gain access to
the technical information needed to help them make the best decisions
without having to travel or take time away from current projects.
Visit the archive to:
- View informative webinars on energy efficiency
- Visit interactive booths where you can contact suppliers
- Peruse the Resource Center where you can download or link to
additional pertinent energy efficiency information
