Fruehauf's detachable trailer let one horse pull five loads.
August Fruehauf's first semi-trailer let a truck drop a box and hook another, doubling the fleet.
Fruehauf Trailer Company
那一手
In 1914 the Detroit blacksmith August Fruehauf built a simple single-axle trailer for the lumber dealer Frederic Sibley, first to carry a boat on a trip, then to haul lumber behind a modified Ford Model T.
The trailer was detachable, so Sibley's truck could work while a trailer was loaded or unloaded, and the fifth-wheel coupling let one man join and unjoin the box with the truck. Fruehauf called it a 'semi-trailer' and it became the ancestor of the highway trailer.
Business grew into the Fruehauf Trailer Company, which added hydraulic dump trailers and the automatic fifth wheel, and the idea that a tractor and its cargo box are separate spread across trucking.
为什么管用
- A detachable box means the truck works while the trailer is loaded or unloaded.
- The fifth wheel lets one driver change trailers, so a tractor serves several boxes
- Standardising the coupling made trailers interchangeable across fleets
- One engine unit can haul more volume, so capital stretches further
可以搬走什么
Separating the mover from the moving box lets one engine serve many loads, and turns a waiting truck into a working one.
后来呢
Fruehauf grew into a leading trailer maker and the semi-trailer became the standard for road freight, with the box and tractor treated as separate assets that fleets can swap. The company later also produced US shipping containers.
