A container sidelifter is a specialised vehicle or semi-trailer used to hoist and transport ISO standard intermodal containers over longer distances.
The container side lifter loads and unloads containers via a pair of hydraulic powered cranes mounted at each end of the vehicle chassis. The cranes are designed to lift containers from the ground, from other vehicles including rolling stock, from railway wagons and directly from stacks on docks or aboard container ships. A standard sidelifter is also able to stack a container at a two containers' height on the ground. If the sidelifter chassis is of 40' length or more, the cranes of the sidelifter can be shifted hydraulically along the sidelifter chassis to be able to pick up either one 20', one 40', or two 20' ISO containers at a time.
As the side lifter is suitable for travelling on general roads for large distances and able to quickly load and unload without additional equipment, it is often used for delivering and picking up shipping containers from within a commercial district. Although these can self load, they are more often loaded or unloaded at the port with a straddle carrier or reach stacker.
The traditional container slide rail elevator is a typical in-line model with stabilizer legs in-line and a boom installed. Other models have a double-sided loader and a dagger leg or leg stabilizer.
The container side jacks can also be classified according to the design of the chassis, for example:
Lattice chassis-this is the original design, very unique in nature. This is the most preferred standard design type. It has a low tare weight and high strength.
I-beam chassis-designed to provide customers with another optional chassis benchmark. Therefore, customers can choose this type according to their own needs and comparison with other products.
The container side lifter consists of the following functions:
Cranes-also called crane modules. These are hydraulic cranes that can lift cargo/containers from the ground, another vehicle, a loading dock, a railway wagon, or any other platform listed above from the top of a container placed on the ground. Can be lifted on the chassis and on the chassis. The crane is usually located on the top of the Sidelifter chassis and can usually move along a chassis that is moved by hydraulic motors or hydraulic cylinders to load containers and cargo of different lengths.

Drive power unit-Generally, cranes are powered by diesel or gasoline engines mounted on trailers. However, it is also possible to power the crane through the PTO shaft of a tractor or truck.
Stabilize the legs. These are hydraulic outriggers used to lift a fully loaded shipping container while keeping the vehicle in place. They prevent the vehicle from tilting. The stabilizing feet can be adjusted to help operate on uneven ground and increase safety and load limit margins when stacking containers. When lifting a container in a narrow location (such as a trailer deck), the outriggers can be extended and tilted to provide additional functions.
Chain. During the lifting operation, chains are installed on the corner castings from the upper part of the crane to the bottom of the container. There is a special connecting device, when placed between 20-foot containers, the user can lock two 20-foot containers together. In this way, the side jacks can haul them like a 40-foot container.
Cab/Tractor. This is used to pull the trailer. In some cases, it is powered by PTO. This accessory also provides compressed air for the brakes in the wheels of the side lifter. Generally, if the side lifter is not connected to the tractor, it cannot be operated. This is so because even if the power pack is carried by the side lifter, the tractor provides much-needed compressed air for the trailer brake and provides extra stability during the lifting operation.
chassis. The chassis is an important structure. It manages the weight of the loaded cargo/container. Not only that, it also supports cranes.
remote control. This is a device operated by buttons and joysticks, basically connected by multiple pairs of wires or by radio signals. This allows the driver to move around the container and observe the unit from different angles when performing lifting operations.

The container side lift trailer is designed to increase various productivity. As will be discussed extensively in this article, the main content includes fast, safe and flexible container handling operations.
Ultimately, you will be able to reduce transportation costs, increase profits and gain a competitive advantage.
Most importantly, these side-frame trailers will improve your ability to move more containers through fast and safe operations.
This is an innovative design that can increase efficiency, save time and ultimately increase productivity. The following are detailed design considerations used in the construction of the container side lifter.
Container transportation-The process of transferring containers from side lifts to flat-top or skeleton trucks is very simple. When extending the stabilizer, there is enough space for the selected trailer to return to the position under the stabilizer during the loading process. If this is not the case, once the flat top or bone trailers are placed side by side, the stabilizer can be lowered. Generally, there is a clearance of more than 300mm on each side of the transfer trailer.
There is a faster turnaround time from start to finish. Even if the side riser is already equipped with a container, the process is faster.

The load can be transferred to a four-axle trailer connected to a four-axle tractor without having to jack up the knives of adjacent trucks and four-axle trailers.
Most importantly, for stability considerations, the lifting module does not need to place the stabilizer legs on the adjacent trailer. The container side lifter can handle containers up to 9'6'.
Stability-The stabilizer legs and outer arm pivot spans of the container side lifter have a large pivot span, providing fast and safe operation even under difficult settings. Due to its high stability, the side loader can lift a considerable weight of up to 45 tons of balanced containers even under undesirable conditions. The center of gravity of the container is about one meter within the stabilizer support line. This is the most stable position you will find in the market. However, there are other options to keep the container's center of mass outside the stabilizer support line. This makes the setting unstable.
Compared with other leg designs that extend downward from the lifting module in a triangular manner, the leg designs are generally praised for their greater stability.
The latter acts as a pivot point and sometimes causes the container side lifter to tip over when loading heavy containers.
Control-The container side jack can be remotely controlled using a radio remote control. A compact user-friendly control device operated with one hand, consisting of a hand-held button control unit, can provide operators with safe working conditions. Using the control system, you can move the two elevator modules with one-button operation and drag the tow bar at a lower speed to achieve fast operation. However, you can control the slower speed when accurately positioning the container. You can also get a fully proportional control system with a handheld toggle remote control system that allows the operator to directly manage the direction and speed of crane movement.

Work space-the container side lifter allows you to work in limited space conditions. The initial station pass option has been specially designed and verified to prevent malfunction during loading and unloading operations in confined spaces. With this feature, you can easily place the container on the wall.
Payload carrying capacity-The range of container side lifts available on the market can provide you with side lifts that can manage huge payload capacity to complete work faster. The ultra-light chassis and lifting modules are light in weight, light in weight, light in design, and well designed to achieve this goal.
In view of the above design considerations, the benefits that can be obtained by using the container side lift are listed below.
It gives you the opportunity to make many container movements every day. You can safely transfer the colorant to the ground within a few minutes. This improves efficiency and productivity.
The lifting operation does not require many operators and equipment. The trailer driver can unload the container by himself in just a few minutes, and can easily move 20-foot and 40-foot containers using the same equipment. No additional personnel or equipment are required. This makes your operations cost-effective.
The conatiner side hoist has a sturdy structure, making it a reliable device with minimal maintenance requirements. It can handle container movements on any type of terrain and can be used on low-cost dry docks.
It can safely handle fragile, valuable and dangerous goods. Differentiated cargo can be easily loaded and unloaded without being confused with any cargo. The side lift action allows you to safely place the container at the exact location you need to facilitate loading and unloading operations when needed.
You can transport containers by road anytime, anywhere. The independent operation ability does not require the support of other equipment during the loading and unloading process, so that the container can be transported by road.

Double-layer container. Since they can work normally in a limited space area, the container side lifter can safely and quickly stack fully loaded 20ft and 40ft containers on each other.
Operating cost-the use of container side lifts can greatly reduce operating costs. This is so because the container is usually left to the customer rather than the trailer. In many cases, customers will drag the trailer to stay behind, which is an ineffective way to use the equipment. For the container side lifter, it is very efficient to transfer from one job to another during the whole day of loading, transporting and unloading containers.
The container side spreader can be used to transport many other goods besides the container. It can handle industrial equipment, special containers (such as portable buildings), fuel containers, etc.
The maximum weight of the Sidelifter equipment is designed to be 45 tons. However, constant innovation and development have brought the latest design to 47 tons.
The same is that there is a smaller version of the device, which can reduce the load when a lighter tare weight is required. When using this equipment, the operator has many choices.
They can tilt the chassis by using stable feet that can work on uneven ground. The operator can also control the lowering and raising of the crane, so this can be done.
The most important thing to note is the telescopic chassis of the side lift, also known as the trombone chassis. This type of chassis allows the equipment to shrink and expand, thereby providing the space needed to accommodate containers of 20 feet, 40 feet, or 45 feet.
The trombone chassis unit is especially suitable for small secondary roads where there is not enough corner space, especially for 40-foot trailers.
