Boarding stairs with canopy. Boarding stairs must be robust and stable, capable of withstanding adverse weather conditions. They are designed to adapt to the curved shape of the aircraft fuselage to which they must be attached, and to be able to raise and lower them to adjust the upper platform to the height of the aircraft, allowing passengers get on and off from the ground to the aircraft ...
Six large cargo hatch covers on a capesize bulk carrier ship as she approaches the Egyptian-Japanese Friendship Bridge. A cargo hatch or deck hatch or hatchway is type of door used on ships and boats to cover the opening to the cargo hold or other lower part of the ship. To make the cargo hold waterproof, most cargo holds have cargo hatch.
Passenger boarding stairs. Passenger boarding stairs, sometimes referred to as boarding ramps, stair car or aircraft steps, provide a mobile means to traverse between the aircraft doors and the ground. Because larger aircraft have door sills 5 to 20 feet (1.5 to 6.1 m) high, stairs facilitate safe boarding and deplaning.
Container ships only take 40's, 20's and also 45's above deck. 90% of the containers that these ships carry are 40-footers and 90% of the world's freight moves on container ships; so 81% of the world's freight moves by 40-foot containers. Most of these 40-foot containers are owned by non-U.S. companies like Maersk, MSC, and CMA CGM.
The most unusual airstair design was found on the Lockheed L-1011, which was a full-height airstair that was stored in a cargo compartment and allowed access from the right aft passenger door to the ground. This design was ultimately so large and heavy, and it took up valuable cargo space, that it was rarely used.
The open hatch bulk carrier, often referred to as OHBC or conbulker, is designed to offer direct access to the hold through cargo hatches which extend the full width of the vessel. As a result, large cargo units can be lowered into place. If it is possible, the holds or hatches are designed around standard cargo unit sizes.
Roll-on/Roll-off car carrying ship being boarded by articulated haulers at the Port of Baltimore RoRo ports and inland waterways of the United States. Roll-on/roll-off (RORO or ro-ro) ships are cargo ships designed to carry wheeled cargo, such as cars, motorcycles, trucks, semi-trailer trucks, buses, trailers, and railroad cars, that are driven on and off the ship on their own wheels or using ...
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]
