The major forces that accelerate a vehicle occur at the tires' contact patches.Since these forces are not directed through the vehicle's CoM, one or more moments are generated whose forces are the tires' traction forces at pavement level, the other one (equal but opposed) is the mass inertia located at the CoM and the moment arm is the distance from pavement surface to CoM.
Her cargo hold was redesigned into a series of decks connected by ramps so vehicles can be driven into and out of the cargo hold for fast loading and unloading. She was also fitted with two pairs of cranes, one pair amidships capable of lifting 35 long tons (36 t), and the other pair aft capable of lifting 50 long tons (51 t). [2]
A unit load device (ULD) is a container used to load luggage, freight, and mail on wide-body aircraft and specific narrow-body aircraft. It allows preloading of cargo , provided the containerised load fits in the aircraft, enabling efficient planning of aircraft weight and balance and reduced labour and time in loading aircraft holds compared ...
Container loaders, also known as cargo loaders or "K loaders", are used for the loading and unloading of containers and pallets into and out of aircraft. The loader has two platforms which raise and descend independently. The containers or pallets on the loader are moved with the help of built-in rollers or wheels.
The Palletized Load System (PLS) is based around two variants of prime mover truck (M1074 and M1075) fitted with an integral self-loading and unloading capability, a trailer (M1076), and demountable cargo beds, referred to as flatracks. PLS trucks and trailers are air-transportable in C-5A and C-17 cargo aircraft. [2]
During the same time, the United States Army started to combine items of uniform size, lashing them onto a pallet, unitizing cargo to speed the loading and unloading of transport ships. In 1947 the Transportation Corps developed the Transporter , a rigid, corrugated steel container with a 9,000 lb (4,100 kg) carrying capacity, for shipping ...
The families of two New Jersey firefighters who were killed battling a July blaze inside a cargo ship said Friday a malfunctioning vehicle being used to load cargo onto the ship caused the fire.
The load can often be expressed as a curve of force versus speed. For instance, a given car traveling on a road of a given slope presents a load which the engine must act against. Because air resistance increases with speed, the motor must put out more torque at a higher speed in order to maintain the speed. By shifting to a higher gear, one ...
