A trailer is not very difficult to categorize. In general, it is an unpowered vehicle towed by a powered vehicle. Trailers are most commonly used for the transport of goods and materials. Although some do enjoy recreational usage of trailers as well.
The public idea of the trucking industry in the United States popular culture has gone through many transformations.However, images of the masculine side of trucking are a common theme throughout time.The 1940's first made truckers popular, with their songs and movies about truck drivers. Then in the 1950's theywere depictedas heroes of the road, living a life of freedom on the open road.Trucking culture peaked in the 1970's as theywere glorifiedas modern days cowboys, outlaws, and rebels. Since then the portrayal has come with a more negative connotation as we see in the 1990's.Unfortunately, the depiction of truck drivers went from such a positive depiction to that of troubled serial killers.
Popular among campers is the use of lightweight trailers, such as aerodynamic trailers. These canbe towed bya small car, such as the BMW Air Camper. Theyare builtwith the intent to lower the tow of the vehicle, thus minimizing drag.
In 1938, the now-eliminated Interstate Commerce Commission (ICC) enforced the first Hours of Service (HOS) rules. Drivers became limited to 12 hours of work within a 15-hour period.At this time, work included loading, unloading, driving, handling freight, preparing reports, preparing vehicles for service, or performing any other duty in relation to the transportation of passengers or property.
The ICC intended for the 3-hour difference between 12 hours of work and 15 hours on-duty tobe usedfor meals and rest breaks.This meant that the weekly maxwas limitedto 60 hours over 7 days (non-dailydrivers), or 70 hours over 8 days (daily drivers). With these rules in place, it allowed 12 hours of work within a 15-hour period, 9 hours of rest, with 3 hours for breaks within a 24-hour day.
The Federal Bridge Gross Weight Formula is a mathematical formula used in the United Statesto determine the appropriate gross weight for a long distance moving vehicle, based on the axle number and spacing. Enforced bythe Department of Transportation upon long-haul truck drivers, it is used as a means of preventing heavy vehicles from damaging roads and bridges.This is especially in particular to the total weight of a loaded truck, whetherbeing usedfor commercial moving services or for long distance moving services in general.
According to the Federal Bridge Gross Weight Formula, the total weight of a loaded truck (tractor and trailer, 5-axle rig) cannot exceed 80,000 lbs in the United States.Under ordinary circumstances, long-haul equipment trucks will weight about 15,000 kg (33,069 lbs). This leaves about 20,000 kg (44,092 lbs) of freight capacity.Likewise, a loadis limitedto the space available in the trailer,normallywith dimensions of 48 ft (14.63 m) or 53 ft (16.15 m) long, 2.6 m (102.4 in) wide, 2.7 m (8 ft 10.3 in) high and 13 ft 6 in or 4.11 m high.
In order toload or unloadbotsand other cargo to and from a trailer, trailer winchesare designedfor this purpose. They consist of a ratchet mechanism and cable. The handle on the ratchet mechanism is then turned to tighten or loosen the tension on the winch cable. Trailer winches vary, some are manual while othersare motorized. Trailer winches are mosttypicallyfound on the front of the trailer by towing an A-frame.
