Hot box
|
- An overheated axle bearing on either a locomotive or wagon.
- A term for an axlebox which has become over heated because of a breakdown of lubrication or excessive overloading. nowadays largely eliminated by the adoption of roller bearing axleboxes which have replaced plain bearing axleboxes. lineside hot box detectors are used by some railways.

- The control of friction and wear by the introduction of a friction-reducing film between moving surfaces in contact. the lubricant used can be a fluid, solid, or plastic substance.
- Смазка
- On no account should oil be used to lubricate pin-tumbler cylinders. graphite is the conventional lubricant for this mechanism.
- Смазка (действие)
- The act of injecting a fluid, normally bentonite and/or polymers, to reduce the skin friction and jacking forces on the jacking pipe during installation. the fluid fills the annular space.
- Means of reducing friction either around a pipe being jacked or a shaft being sunk into the ground.
- The control of friction and wear between two moving, touching surfaces by placing a friction-reducing substance between them.
- Control of friction and wear by the introduction of a friction reducing film between moving surfaces in contact. the film may be fluid, solid or plastic.
- Reduction of friction or wear between two load-bearing surfaces by the application of a lubricant; includes boundary lubrication (thin or interrupted fluid film, especially bearings where wear occurs); mixed film, where some liquid pools support the load; elastohydrodynamic (high-pressure loads increase the lubricant’s viscosity and load-carrying capacity, especially in gears); hydrodynamic (a thick fluid film lubrication, especially in journal bearings) and hydrostatic (external pump pressure used to form a thick fluid film, as in start-up of journal bearings).
Overloading, английский
- Surcharge
- Until the late nineteenth century ships could be (and often were) laden until their decks were almost awash. shipwrecks and crew losses became endemic, but any seaman who signed articles had to sail or risk being named a deserter and arrested. in 1856, an inspector of prisons reported that threequarters of the inmates of jails in south-western england were sailors, imprisoned for twelve weeks for refusing to sail in ships they considered unseaworthy. a decade later, four entire crews were jailed in succession for refusing to sail in a decrepit old tub named harkaway. she finally set sail for the west indies, manned by a fifth crew, but still hazardously overloaded. shipowners strongly resisted all attempts at regulation, and it was not until 1876 british vessels were legally required to indicate their safe laden draft. (see load lines, plimsoll mark.)

Gantry crane, английский
- An overhead crane spanning one or more rail tracks and roadway to allow transfer of loading from a road vehicle, or a rail wagon, to another wagon. the crane may be either running on its own rails or be rubber tyred to allow it to move around a terminal. often referred to as rtg (rubber tyred gantry) or straddle crane.
- Crane with horizontal traverse on which the runner moves forward and back. for container gantry cranes the load is carried by the runner spreader.
