Shipping Container vs Semi-Trailer Which is Better for Freight Shipping

Containers and semi-trailers are ubiquitous forms of transportation and storage in the global shipping sector. These vehicles transport global shippers' commodities. The rivalry between a container and a trailer arises from the many ways in which they vary. When pitted against shipping containers, semi-trailers have the advantage of length diversity. However, the maximum load for both shipping containers and trailers is the same. When coupled with a flatbed trailer, a container may serve as a trailer in a pinch. Which one is suitable for your shipment depends on the circumstances.

Find out how trailers and shipping containers differ from one another and which option is ideal for your needs.

What are the Dimensions of a Semi-Trailer?

Wide varieties of container semi trailer exist, each with its own set of load-carrying capabilities. The lengths of semi-trailers may range from the following examples:

·         28 feet

·         32 feet 

·         34 feet

·         36 feet

·         40 feet

·         48 feet

·         53 feet

Any governmental guidelines do not govern the length of semi-trailers. Semi-trailer length restrictions are set at the state level in the United States. Some jurisdictions permit trailers of up to 57 feet in length.  However, the 53-foot dry van is the most popular semi-trailer in America. This semi-trailer's length, breadth, and height are all about 8.2 feet. 

Semi-Trailer Weight Capacity Limits

A semi-trailer's maximum allowable payload is not standardized. Semi-trailers can often carry more cargo, including greater weight, more pallets, and more loose items, the longer they are.  The maximum payload for the 53-foot dry van trailer is 45,000 pounds. This trailer type also has a high capacity for carrying pallets and parcels. There is enough for 26 standard 48x40-inch pallets in these trailers. However, by double-stacking pallets, you may increase the number of pallets that can be transported by this dry van trailer by 50%.  This would increase the stock of standard pallets to a grand total of Up to fifty-two pallets that may be loaded into a 53-foot dry vehicle. Because most dry vans have a height limit of nine feet, you can't double-stack pallets that are taller than that.

Just make sure there aren't more than a few inches of headroom above the pallet in the trailer. The weight of your package, including any double-stacked pallets, must not exceed the trailer's capacity.  In addition, 53-foot dry van trailers provide enough room for storing non-palletized cargo. This sort of trailer can carry anywhere from 1,000 to 2,000 goods, depending on their dimensions.  

What are the Dimensions of a Shipping Container?

Similar to semi-trailers, shipping containers come in a wide variety of shapes, sizes, and functions. The dry container is the most often used kind of container.

The regular box may be purchased in three distinct sizes. These variants include:

·         10-foot container

·         20-foot container

·         40-foot container

High cube containers are somewhat taller than standard containers. High cubes are one foot taller than containers and may range in length from 20 to 40 feet. The average height of a shipping container is a little over 8.5 feet, but the height of a high cube container is 9.6 feet. 

Shipping Container Weight Capacity

The load capacity of dry containers is comparable to that of semi-trailers. Between 44,000 and 44,500 pounds is the absolute limit.  Comparatively fewer pallets may be transported in a dry container or cube than in a standard 53-foot dry van trailer. Ten normal 48 by 40-inch pallets can fit into a 20-foot dry container or cube, whereas twenty can fit inside a 40-foot one.

Rather than non-palletized freight, palletized freight is always transported in dry containers. However, you may still roughly estimate the number of goods that will be sent in a dry container.  About ten standard 48x40 single-stacked pallets may fit in a 20-foot dry container. A standard pallet of this size may hold 60 cases. This indicates that, on average, the 20-foot dry container can hold 600 boxes. Twenty regular pallets may be transported in a single layer inside a 40-foot dry container. With twice as many pallets, four times as many boxes may be transported. Therefore, around 1,200 standard boxes may be transported in a 40-foot dry container.

What's Better, a Shipping Container or a Semi-Trailer?

Compared to a 40-foot dry container, a 53-foot dry van trailer can store much more boxes and pallets. Not only can you transport more items when utilizing a trailer, but you can also load it with either palletized or non-palletized cargo.


The price of shipping a container is much higher than that of transporting a semi-trailer. The going rate for transporting cargo containers by ship is often between $2,000 and $3,000. The price may change depending on the amount of cargo in each container. They are adding to the expense of transporting a container by securing it to a trailer. Despite the high cost, shipping containers are commonly required for international shipments. Shipping using a semi-trailer saves money. Depending on the items being sent, the price may go up or down, but in most cases, it will be far cheaper than renting a shipping container.

Time of Supply

Goods transported by both containers and trailers are taking longer to reach their destinations than they ever have before. Congestion at the ports is to blame for this situation.  A backlog of cargo ships is waiting to offload their containers at the nearest port. It takes longer to load products onto a trailer and get them where they need to go because of the congestion and wait periods at the ports.


It may seem that utilizing a semi-trailer to transport products is preferable to using containers. However, this is not always the case. Which trailer or container is best depends on your specific transportation requirements.

How to Prevent Typical Shaft Sleeve Issues

Shaft sleeves are cylindrical metal pipes their manufacturers have developed to safeguard pump shafts from wear, corrosion, and erosion at essential points like the stuffing box. The main shaft sleeve is a worn part, like a car’s brake pads, and is developed to be more cost and time effective to replace than the pipe itself, such as the whole braking system. One of the typical issues people face as far as shaft sleeves are concerned while inspecting them is that untidy seal water has cut the shaft sleeves in half, leading to leakage. Temporarily people tightened the shaft sleeve and moved it in an inward direction. Nevertheless, this resulted in a secondary wear sequence and failed to stop the leakage. A second tightening averted the sleeve from revolving and resulted in the developing of a horizontal wear pattern in a single location. At this point, people must realize that they could not repair that shaft sleeve. If the wear patterns have already developed on the shaft sleeve, moving it would just worsen the wear and result in the development of new wear sequences to establish in the region relative to its genuine cause. To better comprehend this, people should think of contaminated and slurry-sealing water such as liquid sandpaper. Both slurry and polluted water can be highly abrasive and corrosive. The movement of the shaft sleeve will relocate the groove and begin the generation of another groove. Tightening the gland compression of the packing decreases the sealing water’s cooling impact; over-tightening it would worsen issues and result in a part failure. The Solution  To avert failure from happening, people could take a few measures to solve and detect problems faced by the shaft sleeve before it suffers from wear and tear. People should make this diagnosis a component of their regular pump maintenance to circumvent early sleeve replacement. The first measure mechanical professionals must take is to examine the sealing water technology for adequate pressure, flow, and quality. Shaft sleeve makers recommend tidying sealing water at continued pressure of ten pounds per square inch above the pump’s discharge pressure. The higher-pressure shutting water would avert the pumped medium from weeping back inside the stuffing box, thus mitigating the wear of shaft sleeves. If the pressure and flow are within specifications, mechanical professionals must check the shutting water for corrosive qualities or/and abrasive particulates. Manufacturers must design the shaft sealing system and apply it according to the pump’s parameters. If people have examined the system and their examination has helped them know that the shaft sleeve has worn out beyond leaking or fixing, they should replace it. Luckily, shaft sleeve makers make shaft sleeves more cost and time-efficient to replace than the whole shaft, making their replacement a “no brainer” as far as their fixing time and cost are concerned. Manufacturers make shaft sleeves with various substances to fight corrosion and wear. As replacing the shaft sleeve is less costly and more straightforward than replacing the whole shaft, the procedure could interfere with and cut down the pace of the entire production. Thus, it is necessary to exercise excellent maintenance practices to add to the life of a shaft sleeve. People can do this by comprehending what leads to shaft wear and knowing their specific pump specifications related to sealing water and flow pressure. How to Avert Failures Due to Shaft Damage Imbalanced Parts As far as impellers are concerned, the imbalanced rotor or impeller can lead to the breaking of the shaft. An unbalanced shaft can result in significant issues for a shaft in what is called a shaft whip. An unbalanced impeller will develop a shaft whip while operating. The impact is the same as if the shaft was deflected or/and bent, although the shaft will measure straight if people checked the shaft and stopped the pump. The amount of bending cycles inside a given duration decreases, but the displacement’s amplitude(strain) continues to fall in the same range as the higher speed factors because of imbalance. Summing up, an imbalanced impeller could result in a shaft’s deformation, which will result in the pump’s lesser efficiency and requirement for a new shaft. Besides the inappropriate installation of an impeller, an inappropriately installed packaging seal could also badly harm a shaft. The ideal way to avert impeller imbalances is to appropriately install the impeller and consider the producer’s specifications otherwise. Flow Interruption One of the other factors responsible for damaging the pump’s shaft is the interruption of fluid flow to the pump. Interruption to water flow could impact the impeller and break the pump shaft and tear away the bearings of the shaft. Another problem regarding an interruption of fluid flow is called hydraulic shock. Hydraulic forces can cause serious damage. For instance, whenever a check valve gets closed. This interrupts the flow of liquid, which results in a massive shock wave. This shock wave travels back and reverses flow downstream. Whenever the shock wave crashes with a pump, the shaft can break or bend instantly or over the passage of time. In order to ensure that the flow does not get interrupted in pumps, it is advisable to apply the appropriate impeller and observe that the clearance level is proper. Else, if absolutely needed, a surge tank mounted on a pumping system can play a key role in stopping interruptions by averting pumping surges. Excessive Vibrations A major cause of a broken shaft is because of excessive vibrations. Sometimes, pump bearings start to wear, permitting the lateral movement of the shaft, making the shaft flex and finally fail. The vibration harmonics also place additional stress on the pump shaft. Obviously, the shaft might not be the just component broken, for extreme vibrations could also harm the mechanical sealing and result in leakages. The ideal practice to avert extreme is by appropriate analysis of vibration on installation, followed by examining vibrations whenever experts perform examinations on a pump. Ideally, experts must monitor a pump every day.
