1.9 Instructions for the
Operator
The Vacuum Hose Lifter is designed to lift and transport items of all kinds.
The maximum lifting capacity must not be exceeded, however. Observe the
name plate!
The loads must be stable enough that they cannot be destroyed during raising!
Transport of persons and animals with the load or the lifting device itself is
forbidden!
Unauthorized alteration of the lifting device is forbidden for safety reasons!
Only suction plates of the manufacturer PROBST shall be used!!!
Some suction plates which can be mounted to the device will reduce its carrying
capacity.
The maximum load is indicated on each suction plate.
Use only suction plates which are approved for this device!
Do not exceed the maximum carrying capacity of the suction plates!!!
Danger: Load (stone slabs) will fall down!
The use of suction plates with a smaller carrying capacity than the lifting unit is
forbidden! Danger: Load will fall down.
(It is permissible to use suction plates with a higher carrying capacity than the
lifting unit).
The use of this device is only permitted in proximity to the ground.
The Load must not be lifted above 1,8 m (70,8 inch)!
The equivalent continuous sound pressure level amount in operation
(workpiece sucked on) is for the Vacuum Hose Lifter below 70 dB (A).
The load is held at the suction head by underpressure. If there is a sudden
interruption of the vacuum generator, the underpressure at the suction head
decreases. As a result the lifting tube of the device descends and the load
lowers.
This happens in a sudden power failure. A non-return valve in the rotary suction
fitting ensures that the vacuum can escape only slowly. However, this will work
only when the regulator lever is moved to "Lift".
When power fails, immediately put the load down if possible. If this is not
possible, immediately leave the dangerous area near the load.
The device generates a very strong suction which can draw in hair and clothing.
Do not look into the suction opening or place small objects close to suction
openings when the device is switched on.
The workplace of the operator is in front of the control unit.
Make sure, that there will be no unauthorized operating of the main switch from
the lifting device (for example with a padlock at the main switch).
Never stand below the load.
As an operator of the lifting device you must be trained before start-up. You
must have read and understood the operating instructions and especially the
chapters "Safety" and "Operating".
Be sure, that only authorized persons use the device. You are responsible for
others in the operating range of the equipment.
Local safety requirements are fully applicable. Safety instructions in this
document are complementary to the rules in force and do not supersede the
latter.
