Variable spring hanger. Variable effort supports also known as variable hangers or variables are used to support pipe lines subjected to moderate (approximately up to 50mm) vertical thermal movements. VES units (Variable effort supports) are used to support the weight of pipe work or equipment along with weight of fluids ( gases are considered ...
The central element is the equalising beam, on which a spring set (with an inner and an outer coil) rests at each end. Other components are, from left to right: an axlebox with roller bearing; a pair of swing links and short beam supporting a nest of coil springs and a vertical hydraulic motion damper; and a horizontal torsion bar.

Attempts have been made to increase the safety of bridges with pin and hanger assemblies by adding some form of redundancy to the assembly. Retrofits that add redundancy to pin and hanger assemblies include adding a "catcher's mitt"—a short steel beam attached to the bottom of the cantilevered girder that extends out beneath the suspended girder to "catch" the suspended girder should ...
The beam is connected at each end to a spring on an axle or to the end of another equalising beam (usually via a vertical spring hanger) to distribute the locomotive's weight between two or more axles. The frontmost and rearmost components are secured to the locomotive frame.
Hyundai and Kia are recalling over 208,000 electric vehicles to fix a pesky problem that can cause loss of drive power, increasing the risk of a crash. The recalls cover more than 145,000 Hyundai ...
In a typical diverter switch, powerful springs are tensioned by a low power motor (motor drive unit, MDU), and then rapidly released to effect the tap changing operation. To reduce arcing at the contacts, the tap changer operates in a chamber filled with insulating transformer oil, or inside a vessel filled with pressurized SF 6 gas. Reactance ...
