SK 2055 / 2070 / 2090
System
Specifications
The design has been calculated to enable a maximum load on
any one arm of:
• SK 2055: 2060 kg
• SK 2070: 2625 kg
• SK 2090: 3375 kg
Lifting
system
This hydraulic 2-post vehicle lift is equipped with a single
hydraulic unit (on post I). The unit drives the two cylinders in
parallel.
Control
system
The control receives signals from the two potentiometer units on
top of the guide pieces. Each potentiometer measures the height
of the guide piece via a wire connected to the post.
There is also a mechanical height safety as an additional safety
feature.
The control system continuously monitors the situation.
Adjustments to elevation differences are only possible during
raising and lowering.
Controls
The controls correct any elevation differences greater than 15
mm by opening the hydraulic correction valve so that oil can flow
out of the highest cylinder until the elevation difference is zero
again.
Monitoring The lowering action is interrupted if elevation differences have
arisen (e.g. due to obstacles below the arms). Because of the
obstacle, one guide piece will no longer be able to lower. If the
elevation difference exceeds 30 mm, the lowering action will be
halted. The control voltage status will blink rapidly.
It will still be possible to raise the lift. Raising eliminates the
elevation difference and the vehicle lift can be lowered again
once the obstacle has been removed. If the elevation difference
exceeds ±60 mm, the control power will be interrupted and
operation of the vehicle lift using the push buttons on the control
boxes will be disabled. The control voltage status on the control
box will blink slowly.
The data on the type plate is required for the (electrical) installation and for
ordering spare parts.
