Chapter 2: How to operate and use self loading trailer?

How to lift a shipping container with a crane?

Operator should be familiar with this machine, keep it in the best status. 

1.To ensure safety, check whether sidelifter is work normally and in accordance with requirements of goods to be lifted before operation. Make sure that the sidelifter is not overloaded. Refer to the sidelifter working range to make sure that the unbalance loading of front and rear does not exceed 10% of that at corresponding working range, and keep container a proper distance of 300mm~500mm from chassis if it is possible.

2.Two hydraulic arms, mounted on an attached vehicle, on the trailer of a truck, on a standard 2 or 3 axle truck or on a railroad car, which allows access to the load, make it possible to load or unload standard containers from a maximum weight.The process is executed by means of a radio control system located in the truck.

3.When load just leaves ground, please ensure there is no obstacle in load traveling direction.Do not make the container center beyond the stabilizers limits, otherwise, it may result in overturn accident.Be sure to keep all wheels contact with ground when extending stabilizers.During operation, do not retract stabilizers.

4.The working range of front lift equipment and rear lift equipment should be mostly same. When difference occurs, stop one lift equipment and operate another lift equipment, adjust them to enable the front lift equipment is the same work range as the rear lift equipment, then operate them at the same time again.

5.During lifting, make sure the lifter act smoothly and steady, if the container swing being lifted because of abrupt operation, stop the operation at once, restart the operation after quieting down.

6.When perform inspection and maintenance work, be sure to avoid collision, and do no knock the parts fiercely to prevent them from distortion , and keep these parts from dust when working on them, in addition, add and inject grease to prolong their life.

7.All the movement parts of the machine are driven by hydraulic, when you find abnormal sound during operation, stop operation at once, restart operation after get rid of faults.

We also recorded a video of the operation of the container lifter trailer, please watch the video to understand the operation and use.

1.Wireless remote control, equipped with imported remote control, easy to operate.

2.Chains.They are attached from the top of the cranes to the corner corners at the base of the container (s) during lifting operations.There is a special link device that, when placed between two 20-foot containers, allows the user to lock two 20-foot (2 TEU) containers together, which allows the container-lifter to lift them up as if they were a 40-foot container. feet.

3.Chassis.It supports the weight of the container when it is loaded, it also supports the cranes.

4.Crane Lift.Hydraulically powered cranes lift the container (from the ground, the loading dock, another vehicle, the rail car or from the top of another container placed on the ground or other location) into and out of the chassis.These cranes are placed in the upper part of the side chassis and can usually be moved along the chassis moving with hydraulic cylinders or hydraulic motors to load different lengths of containers.

5.Boom slide system. The 20ft or 40ft container can be loaded and unloaded through the sliding of the front and rear cranes, which has a wide range of applications and good versatility, greatly expanding the use of the equipment.

6.Trailer Stabilizer Legs.These are equipped with hydraulic legs that are necessary to allow the lifting of loads of up to 44 tons without tilting the vehicle.These can be adjusted to help the operation in a level less terrain and facilitate greater safety margins and load limits when stacking containers.

7.WABCO braking system reduces best sidelifter truck sacramento braking distance.
