Authorized use
The device (FTZ-UNI-15) is universal usable for gripping and moving customary prefabricated concrete products,
with clean gripping surface; like steps, kerbs (also natural kerbs), as well as "Kassler Bord" (Bus- and Train-profil-
stones) and so on. Connected with lifting equipment e.g. a excavator or a crane.
ATTENTION: The use of this device is only permitted in proximity to the ground (→ chapter
"Safety at work" and "Explanation of basic concepts").
Only stone elements with parallel and plane surface are allowed to be picked-up and handled.
Because the gripping good could fall down.
NOT ALLOWED ACTIVITIES:
Unauthorized alterations of the device and the use of any self-made additional equipment could cause
danger and are therefore forbidden!
Carrying capacities / working load limits(WLL) of the device must not be exceeded and nominal
widths/gripping ranges must not be exceeded or fallen below.
All unauthorized transports with the device are strictly prohibited:
•
Transport of people and animals.
•
Gripping and transporting of other loads and materials than described in this operating instruction.
•
Never suspend any goods with ropes, chains or similar at the device, except at the designated lifting
eyes/-bolts.
•
Gripping of gripping goods with packaging foil, because they could fall down.
•
Gripping of gripping goods with surfaces that reduce the coefficient of friction (e.g., abrasive,
treated, dirty, frozen, coated, painted surfaces), as this causes a reduction in the coefficient of
friction between the grippers and the gripping goods → Danger of slipping!
Remedy: In case of dirt of any kind, it is absolutely necessary to clean the grippers and the surface
of the products in the area of the grippers before each gripping process!
•
Gripping of gripped goods, which can deform or break
due to the clamping force of the gripping device!
•
Gripping of goods which show visible damage, or which
may break due to their own weight.
•
Gripping and transporting of non-rectangular and round
gripping goods, because they could fall down (see
figure to the right). ➔
•
Transportation of material with "feet", "bellies" and "blind
spacers".
