The bellow cylinders can also be used in the process of loading and unloading shipment from trucks. We are able to find this application in dock levellers.

Bellow cylinder placed in lock levellers
When we talk about the dock levellers in order to put the goods into the truck, we may need to use an actuator so as to lift up the ramp during the loading process. Different alternatives might be used as an actuator.

Convoluted bellow cylinders in dock levellers
The convoluted bellow cylinder is a reliable solution for lifting the ramp in docks. With bellow cylinders we have the possibility to adjust the air pressure and volume of the actuators. In addition, it does not require much space and depending on the bellow, if we need an important stroke, with the ORIA bellow cylinders, it is possible to select from a 1 convoluted bellow to a 3-bellow cylinder actuator.
Benefits of using the bellow cylinder in dock levellers
The rubber bellow cylinders have an incredible strength, as well as lifting capabilities and do not require the use of excessive electricity as other actuators. By this way, we can avoid the cost of the electrical infrastructure if we have an air supply as a compressor, so that we can adjust the volume of the bellow cylinder. It is practical and fast while operating, and the rubber body is almost indestructible. Does not require any maintenance, just a periodical inspection should be carried out.
