With the support wheels in the descend position the LIFTKAR can be rolled over the
step margin and the support wheels will, under controlled conditions, lower the
machine onto the next step down. When the main wheels land on the lower step, the
support wheels automatically rotate to the descend position for the descent onto the
next step down, all within approx. half a second.
During the descent movement the indicator light changes to constant red. After
reaching the descend position the light changes back to flashing green.
Important:
As soon as the LIFTKAR rolls off the tread, ensure the main wheels are kept
against the rise until the support wheels reach the descend position.
Just before the suspension arm reaches the descending position, the support
wheels reach the upper edge of the stair and lift the LIFTKAR approximately
10 mm. This is normal and is used as an advance signal by experienced
drivers. As a matter of fact, you may already advance while the support
wheels are in contact with the floor. This results in smooth continuous down-
the-stairs motion.
In the case of closed stairs with short step, for instance on the inside of narrow
circular staircases, the support wheels may touch the stair step and the
LIFTKAR can move approximately 8 to 9 cm forward. This also is normal since
the LIFTKAR will then be ready for advancing again anyway.
If the load is under 15 kg or the driver holds back the load, the automatic
movement to the descend position will be slowed down.
Unlike all other stairclimbers the operator does not need to control the electrics to
descend, as the support wheels operate automatically.
4.3 Please pay attention to
4.3.1 Shift of balance
When ascending the balance of the load changes as
soon the support wheels start lifting the load.
Operators quickly become accustomed to this and
compensate by tilting the handle.
Initially, before this operation becomes automatic,
care should be taken at the point where the support
wheels take the load when ascending. There is a
forward movement of the machine which is easily
compensated for by tilting the handle backwards.
Lowering backwards by 10° to 20° before the
support wheels start to lift eliminates any major
forward movement.
