Buffers

PGB - Movable buffer

PGB

Buffers are designed to protect the building and installed docking equipment against direct contact with a vehicle during docking process.

Docking process may be associated with very high load, exceeding 100 kN. Buffers manufactured by PROMStahl company guarantee smooth transfer of that load onto the building structure and they allow to keep appropriate distance between the building and the vehicle. Thus, they prevent potential damage to the building, docking equipment and docked vehicle.

Buffers of PGB type are one of numerous customized solutions offered by PROMStahl. Movable buffers of PGB type operate in so called floating condition. The buffer is nominally aligned with the dock top edge and it can move vertically 150 mm upwards and downwards. This means that it can move vertically together with the bed of the trailer which is repeatedly loaded and unloaded during docking process. Thanks to floating system, buffers are less exposed to mechanical damage, which, in return, significantly increases their life. The steel structure is hot dip galvanized in a standard version, which ensures durable anticorrosive protection. All buffers manufactured by PROMStahl are made of high quality rubber. The buffers are available with damping components of two different thicknesses: 90 and 140 mm. The buffer is welded to the dock wearing iron and the dock frame or anchored in the wall.
