The mechanical AMTR-J bridge is designed for use in all kinds of industrial facilities where an additional docking system is required. It is recommended primarily for facilities where it is not possible to install levellers or where smaller delivery trucks are unloaded.

The AMTR-P inflatable seal is the most effective and the most durable of all types of docking system seals. The air bags are harmonica-shaped, which creates an optimal seal. This type of seal is especially recommended in cases of significant differences in temperature inside and outside the room, for example in air-conditioned or cooled storage areas. Seals with non-standard dimensions can be designed.

Both the tubular and blower seal motor are operated with one button. When the truck is being docked for unloading, the engines seal the space between the open gate and the vehicle within 30 seconds.

The upper seal air bag is extended by the shaft of the tubular motor. During expansion, the blower motor ensures that the bags are filled with air.
