Description 

Persons who are wheelchair-bound can be embarked into or 

disembarked from a vehicle using the linear lift. 

The main components of the linear lift are: 

y

 

the platform, 

y

 

the lifting unit with carrier arms, guardrails and floor anchorages, 

y

 

the hydraulic system and 

y

 

the operating controls. 

The aim of this chapter is to illustrate the construction and function 

of the linear lift. To this end, the individual assemblies and compo-

nents are described in the following sections. 

2.1
