2.1 Authorized inset
The FTZ-BB is universal usable for gripping and moving customary prefabricated concrete products, with
clean gripping surface; like steps, kerbs (also natural kerbs), as well as kerb stones with high concave section
for bus stops („Kassel Kerb") 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").
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".
