Description of the Vertical Lift System (VLS)
The "Vertical Lift System" (VLS) is an operator assistance
system that makes operating the machine easier with a
semi-automatic telescoping movement when raising or
lowering loads. The almost vertical raising and lowering
movement of the boom improves machine stability.
When it is raised, the boom only automatically extends in
the upper range if forklift mode is switched on
When it is lowered, the boom automatically retracts in the
upper range if forklift or bucket mode is switched on. This
ensures that the machine cannot suddenly reach the
overload range and tip over to the front.
Information
The boom does not extend automatically in the case of
loads over 700 kg.
