In the United States, the term is sometimes used interchangeably with travel trailer and mobile home, varieties of trailers and manufactured housing designed for human habitation. Their origins lay in utility trailers built in a similar fashion to horse-drawn wagons. A trailer park is an area where mobile homes are placed for habitation.

In the United States trailers ranging in size from single-axle dollies to 6-axle, 13 ft 6 in (4,115 mm) high, 53 ft 0 in (16,154 mm) long semi-

trailers are commonplace. The latter, when towed as part of a tractortrailer Шr “18-аСООХОr”, carries a large percentage of the freight that travels

over land in North America.

Some trailers are made for personal (or small business) use with practically any powered vehicle having an appropriate hitch, but some trailers are part of large trucks called semi-trailer trucks for transportation of cargo.

Enclosed toy trailers and motorcycle trailers can be towed by com-

monly accessible pickup truck or van, which generally require no special permit beyond a regular НrТvОr’s ХТМОЧsО. Specialized trailers like open-air

motorcycle trailers, bicycle trailers are much smaller, accessible to small automobiles, as are some simple trailers, pulled by a drawbar and riding on a single set of axles. Other trailers, such as utility trailers and travel trailers or campers come in single and multiple axle varieties, to allow for varying sizes of tow vehicles.

There also exist highly specialized trailers, such as genset trailers and their ilk that are also used to power the towing vehicle. Others are custombuilt to hold entire kitchens and other specialized equipment used by carnival vendors. There are also trailers for hauling boats.

Tramac by Montabert Technology

Built with unique advanced technology, Tramac by Montabert Hydraulic patented designs offer breakers of high quality, high productivity and unbeatable robustness.

All Tramac by Montabert breakers utilize solely 100% oil pressure for the creation of piston energy. A sealed rubber diaphragm accumulator combined with the pressure regulator which continually adjust a constant percussion pressure independently from delivered flow but also prevent the rubber diaphragm from impacting the accumulator flange. The energy recovery valve allows a real recovery of piston rebound energy (up to 30%) by recycling a certain quantity of oil directly into the accumulator.

Tramac by Montabert is also well known to be the leader in the variable stroke change technology.

All models from our "V Series" adapt automatically the impact energy to the material resistance. For each blow, a sensor checks the rebound of the piston.

All of these features are part of our new tool-guiding known as TPS (tool protection system) which increase the tool retainer life span, increase the upper and lower bushing life span allow Tramac by Montabert Breakers to offer higher reliability, higher availability and higher performance.

Inside every Tramac by Montabert breaker, an automatic pressure regulator reduces pressure variations, preventing overheating, and extending the life of the breaker. In addition, Tramac by Montabert breakers nev-

er lose power and productivity like nitrogen-assisted breakers.

In contrast, Tramac by Montabert breakers use hydraulic flow to move the piston up and down. On the up stroke, excess oil is stored in a fully enclosed energy chamber. Once the piston reaches the top of its stroke, high-pressure hydraulic flow is diverted, and forces the piston downward. Towards the end of the stroke, stored oil from the energy

chamber is released to complement flow from the carrier and to compensate for the piston's high velocity. Then the cycle repeats for constant power and performance with every blow.

Buckets in mechanical engineering can have a distinct quality from the traditional bucket (pail) whose purpose is to contain things. Larger versions of this type of bucket equip bucket trucks to contain human beings, buckets in water-hauling systems in mines or, for instance, in helicopter buckets to hold water to combat fires.

Two other types of mechanical buckets can be distinguished according to the final destination of the device they equip: energy-consumer systems like excavators or energy-capturer systems like water bucket wheels or turbines.

Buckets exist in a variety of sizes or shapes. They can be quite large like those equipping Hulett cranes, used to discharge ore out of cargo ships in harbours or very small such as those used by deep-sea exploration vehicles.

The shape of the bucket can vary from the truncated conical shape of an actual bucket to more scoop-like or spoon-like shapes akin to water turbines. The cross section can be round or square.
