Liquid hydrogen trailer
Encyclopedia
A liquid hydrogen trailer is a trailer
designed to carry cryogenic liquid hydrogen
(LH2) on roads being pulled
by a powered vehicle
. The largest such vehicles are similar to railroad tanktainers which are also designed to carry liquefied loads. Liquid hydrogen trailers tend to be large; they are insulated
. Some are semi-trailer
s.
was a liquid hydrogen trailer designed in the 1950s to carry cryogenic liquid hydrogen
(LH2) on roads being pulled
by a powered vehicle
. It was constructed by the Cambridge Corporation and had a capacity of 26000 l (6,868.5 US gal; 5,719.2 imp gal) with a hydrogen
loss rate of approximately 2 percent per day. The U-1 was a single axle
semi-trailer
. The specifications for its successor the U-2, a double axis semi-trailer, were issued on 15 March 1957.
Semi-trailer
A semi-trailer is a trailer without a front axle. A large proportion of its weight is supported by a road tractor, a detachable front axle assembly known as a dolly, or the tail of another trailer...

Liquid hydrogen
Liquid hydrogen is the liquid state of the element hydrogen. Hydrogen is found naturally in the molecular H2 form.To exist as a liquid, H2 must be pressurized above and cooled below hydrogen's Critical point. However, for hydrogen to be in a full liquid state without boiling off, it needs to be...

Towing
Towing is the process of pulling or drawing behind a chain, line, bar or some other form of couplings. Towing is most visibly performed by road vehicles, but anything from waterborne vessels to tractors to people can tow cargo. Troop carrying and cargo carrying gliders were towed behind powered...

Thermal insulation
Thermal insulation is the reduction of the effects of the various processes of heat transfer between objects in thermal contact or in range of radiative influence. Heat transfer is the transfer of thermal energy between objects of differing temperature...

Axle
An axle is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to its surroundings, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle...
