Side Lifter Trailer Design Features
Lifting Cranes– Also known as crane modules. These are hydraulically powered cranes that lift the cargo/container either from the ground, another vehicle, a loading dock, a railway wagon or straight from the top of another container placed on the ground from any other platform as listed above. Lifting is possible on and off the chassis. The cranes are normally located at the top of the Sidelifter Chassis and are usually able to move along the chassis that is being shifted through the hydraulic motors or the hydraulic cylinders in order to load different container and cargo lengths.
Driving Power Unit– Typically, the cranes are powered through a trailer mounted diesel or gasoline engine. However, the cranes can also be powered through a PTO from the tractor or the truck.
Stabilizing Legs. These are hydraulic legs that are used in the lifting of a fully laden shipping containers while keeping the vehicle in position. They prevent the vehicle from tilting. The stabilizing legs can be adjusted to aid operations on uneven ground and enhance greater margins of safety and load limits when stacking the containers. The legs can be extended and tilted to provide extra capabilities when containers are lifted in confined locations such as on trailer decks.
Chains. There are chains attached from the upper part of the cranes to the corner castings at the container base when performing lifting operations. There is a special connecting device that when placed between 20ft container makes it possible for the user to lock together two 20ft containers. This allows the side lifter to haul them as though they were one 40ft container.
The Cab/Tractor. This is used to pull the trailer. In some scenarios, it supplies power via the PTO. This accessory also supplies compressed air for the brakes in the wheels of the side lifter. Usually, the side lifter cannot be operated without connecting it to the tractor. This is so because even though the power pack is carried by the side lifter, the tractor provides the much-needed compressed air for use on the trailer brakes and also extra stability during the lifting operations.
Chassis. The chassis is an important construction. It manages the weight of the loaded cargo/container. More than that, it supports the cranes.
The Remote Control. This is a device that is operated with buttons and joysticks and are basically attached through a multi-pair electric wire or through a radio signal. This allows the driver operator to move around the container and have a view of the unit from different angles when conducting the lifting operation.
Side Lifter Trailer Design Considerations
Container transfer – The process of transferring a container from a side lifter to a flat-topped or skeletal truck is straightforward. When the stabilizers are extended, there is sufficient room for the chosen trailer to back into position under stabilizers during loading. If not, the stabilizers can be let low once the flat-topped or skeletal trailer has been positioned alongside. Normally, there is more than 300mm clearance present on each side of the transferring trailer.
There is a faster turnaround time from the beginning to the end. The process is also faster even when the side lifter is already loaded with a container.
Load can be transferred to a Quad axle trailer linked to a four-axle tractor without the need to jack knife the adjacent truck and the Quad axle trailer.
Most importantly, the lift modules do not need to place the stabilizer legs on the adjacent trailer for purposes of stability. The side lifter trailer can handle containers of up to 9’6’ high.
Stability– The side lifter trailer has a wide span for the stabilizer leg and the outboard jib pivot that provides quick and safe operations even under difficult settings. Due to this high stability, the side loader is in a position to lift a considerable weight of up to 45 tonne balanced containers even under undesirable conditions. The center of container gravity is about a meter within the stabilizer support line. This is the most stable position you will ever find in the market. However, there are other options that have the center of container mass outside the stabilizer support line. This makes the set up less stable.
Control– Side lifter trailer can be remotely controlled using a radio remote control. The compact, user-friendly control operated using one hand and composed of a handheld pushbutton control unit enhances safe working conditions for the operator. With the control system, you can move both the lift modules using a single button operation using tow depression levels at quick speeds for a fast operation. Still, you can control a slow speed when doing accurate and precise positioning of your containers. You can also get a fully proportional control system that comes with a handheld toggle remote control system that makes it possible for the operator to directly manage the direction and speed of the crane movement.
Working Space – The container side lifter gives you the possibility of working in limited space conditions. The original leg over option has particularly been designed and proven against failure during both loading and offloading operations in restricted spaces. Through this capability, you can easily place your container against a wall.
Payload carrying capabilities– The range of container side lifters available in the market can give you side lifters that can manage a great payload capacity to work on your job faster. This is made possible through the ultra-high-tensile chassis and lift modules that are lightly-designed and well-engineered in a remarkably low tare weight.
Loading: Side lifter trailer has a set of hydraulic arms or lifting forks that extend from the side of the vehicle. These arms are capable of lifting heavy loads, such as containers or long beams, directly from the ground or from an appropriate loading platform. The arms are adjustable to accommodate different load sizes and weights.
Lifting: Once the load is secured onto the lifting arms, the hydraulic system is engaged, and the side lifter trailer lifts the load upwards. This lifting mechanism can raise the load to a sufficient height for transportation, reducing the need for additional lifting equipment.
Maneuvering
Side lifter trailer are equipped with wheels or tracks that allow them to move in different directions. They can be driven forwards, backwards, or sideways to navigate through tight spaces, such as warehouses or shipping yards. This maneuverability is achieved through hydraulic controls that control the movement of the wheels or tracks.
Transporting
Once the load is lifted and the side lifter trailer is positioned correctly, it can be driven to its destination. Some side lifter trailer are designed for road travel, while others are used within a confined area, such as a shipyard or construction site.
Unloading
When the side lifter trailer reaches its destination, the hydraulic arms lower the load to the ground or a suitable unloading platform. The load is then released, and the side lifter trailer can move on to the next task.
