Description
"A semi-trailer is a trailer without a front axle. A large proportion of its weight is supported by a tractor unit, a detachable front axle assembly known as a dolly, or the tail of another trailer.

A semi-trailer is normally equipped with landing gear (legs which can be lowered) to support it when it is uncoupled."

Conveyor systems are mechanically-operated material handling equipment, which are used to transport material within premises. They provide a quick and effective transportation solution with a high degree of safety. Therefore, due to effectiveness of conveyance, a considerable amount of cycle time is reduced in the industrial process. The same factor helps in reducing the errors in handling manual material. Early commercialization of the conveyor system took place for transportation of heavy materials in the industrial sector.
