Operation & Service Manual (VA) 37 ST1175
4.7 Control box
The control panel on the front of the control box has all functions necessary to
control the operation of the column lift. There is a two-position switch on the
control panel of the main column that can also be used as an emergency switch.
The components of the control panel and their functions are described in chapter
Operation (on page 39).
4.8 Pallet lifting mechanism
The pallet lifting mechanism is fitted with two wheels, and is used for relocating the
column lift. These are mounted at the back to safeguard the column lift against
toppling over when it is being relocated. When relocating the column lift, the pallet
lifting mechanism raises the rear of the column off the floor so that it can be moved
more easily.
4.9 Retractable wheels
The front wheels are controlled simultaneously with the lifting and lowering of the
pallet lifting mechanism
4.10 Locking feature
If the hydraulic pressure fails while a vehicle is being raised, lowered or standing
still on the lifting system, a mechanical safeguard will ensure that the vehicle
cannot fall.
The characteristic clicking sound indicates that the locking pawl is activated. When
lowering, the pawl is retracted by a solenoid.
