The stairs come with a chassis developed by LAS-1. A diesel engine is used.

The passenger stairs have a stepless automatic hydrodynamic gear manufactured by Graziano/Oerlikon (Italy).

A UK-manufactured drive axis has been installed in the chassis. It is designed to be used under a heavy load and is used in machines with a high load on the axes. In conjunction with major wheel diameter and spring-loaded rear suspension it ensures high reliability, high passing ability on all types of aprons and smoothness of movement.

The self-propelled chassis is equipped with a one-man closed cabin with ventilation and heating.

The stair is produced in two modifications: with an open stair and closed stair with an entrance and bellows gangway.
