Hardtop containers are a special version of common dry containers. The main difference between a regular ISO container and a hardtop container is that the latter has a removable roof and the door header can be rotated outwards, which makes loading and unloading cargo with a forklift much easier.
These are mainly used to transport heavy to very heavy cargo that needs to be loaded through the roof opening or door side. It can be used not only as a general cargo container but also as an open top container. Here’s everything you need to know about these very useful containers.
About hardtop container
Contrary to its name, the hardtop container has a removable roof that makes it easy to move cargo inside the container. Made of corrugated steel, the floor is made of wood to reduce friction. Most hardtop containers have a ring on the roof to accommodate the forklift so they can be removed smoothly using the forklift. The roof weighs about 450 kg.
The biggest advantage of a hardtop container is that if the cargo height exceeds the container height, a removable roof can be secured to the inner side wall of the container. This allows you to convert to an open top container. Therefore, freight carriers and shippers prefer to purchase hardtop containers that can be easily converted to open tops or used as standardized containers, depending on their requirements.
Lashing rings on top and bottom side rails, corner posts (capable of handling loads up to 2000 kg), and center of side walls (with a load capacity of 500 kg) to securely secure cargo in the container It is attached to. The roof of the container is closed.
Like standard ISO containers, hardtops have dimensions of 20 feet and 40 feet. They can also be found in the high cube dimension. The appearance of the top container is as follows.
Hardtop container: Dimensions
Containers are created according to the standard size set by the International Organization for Standardization (ISO). Hardtop containers are available as 20-foot, 40-foot, and high-cube containers. The internal measurements and capacities of these containers are as follows:
|Measure||20ft HT||40ft HT||40ft High Cube HT|
|Internal length||5.89 m / 19.3 ft||12.03 m / 39.5 ft||12.03 m / 39.5 ft|
|Internal width||2.34 m / 7.8 ft||2.34 m / 7.8 ft||2.34 m / 7.8 ft|
|Internal height||2.38 m / 7.9 ft||2.38 m / 7.9 ft||2.69 m / 8.9 ft|
|Tare weight||2,700 kg / 5,950 lbs||4,700 kg / 10,362 lbs||5,200 kg / 11,470 lbs|
|Payload capacity||27,780 kg / 61,244 lbs||27,300 kg / 60,180 lbs||28,600 kg / 63,052 lbs|
|Cubic capacity||33.0 m3 / 1,165 ft3||65.3 m3 / 2,306 ft3||76.3 m3 / 2,694 ft3|
Hardtop containers are used to transport all types of common dry and bulk cargo, including cement, automobiles, construction materials and steel. These work especially well for heavy and very heavy cargo, as well as tall cargo. Roofs or doors with forklifts, cranes, or crabs. Freight transported using hardtop containers in particular includes marble, glass plates, raw materials (such as coal) and large machinery.
How much can it fit in a 40-foot hardtop container in terms of volume?
760 Nakagi. Or 1200 small packing boxes. Or the contents of four two bedroom houses.
However, to simplify things with standard size, the European pallet size (1.2mx 0.8m) allows you to fit 30 pallet stacks in a 40-foot hardtop high-cube container. For an American pallet (1.01mx 1.21m), it fits in a stack of 25 pallets.
