RATED LIFTING CAPACITIES

ISO4305

NOTES FOR "ON OUTRIGGERS" TABLE

1. Rated lifting capacities shown in the table are based on
condition that crane is set on firm level surface. Those
above bold lines are based on crane strength and those
below, on its stability.

2. Retad lifting capacities based on crane stability are
according to ISO 4305.

3. The mass of the hook (350 kg for 30 t capacity, 100 kg
for 3 t capacity), slings and all similarly used load han­dling devices must be added to the weight of the load.

4. For rated lifting capacity of single top, reduce 350 kg
from the relevant boom rated lifting capacity. Rated lift­ing capacity of single top should not exceed 3,000 kg.

5. Standard number of parts of line for outrigger operation
should be according to the following table. Load per line
should not surpass 31.4 kN {3,200 kgf} for main winch
and 29.4 kN {3,000 kgf} for auxiliary winch. The lifting
capacity data stored in the AUTOMATIC MOMENT LIM­ITER(AML-L) is based on the standard number of parts
of line listed in the chart. Maximum lifting capacity is
restricted by the number of parts of line of AUTOMATIC
MOMENT LIMITER(AML-L).

6. The over-side rated lifting capacity depends on outrigger
extension. Rated lifting capacity of over-front and over­rear assume fully extended outrigger position.
Working area for each outrigger position are given sepa­rately and must be followed accordingly during opera­tion.

RATED LIFTING CAPACITIES

ISO4305

NOTES FOR “ON TIRES” TABLE

1. Rated lifting capacities shown in the table are based on
condition that crane is set on firm level surface, with
suspension lock applied. Those above bold lines are
based on tire capacity and those below, on crane stabili­ty. They are based on actual working radii increased by
tire deformation and boom deflection.

2. Rated lifting capacities based on crane stability are
according to ISO4305.

3. The mass of the hook (350 kg for 30 t capacity, 100 kg
for 3 t capacity), slings and all similarly used load han­dling devices must be added to the weight of the load.

4. For rated lifting capacity of single top, reduce 350 kg
from the relevant boom rated lifting capacity. Rated lift­ing capacity of single top should not exceed 3,000 kg.

5. Without outriggers lifting with "jib" is not permitted.
Maximum permissible boom length is 22.1 m.

6. CREEP is motion for crane not to travel more than 60 m
in any 30 min. period and to travel at the speed of less
than 1.6 km/h.

7. During "CREEP" duties travel slowly and keep the lifting

load as close to the ground as possible, and especially
avoid any abrupt steering, accelerating or braking.

8. Do not operate the crane while carrying the load.

9. Tires should be inflated to their correct air pressure of
900 kPa {9.0 kgf/cm

2

} : 445/95R25

10.Standard number of parts of line for on tires operation
should be according to the following table.
The lifting capacity data stored in the AUTOMATIC
MOMENT LIMITER(AML-L) is based on the standard
number of parts of line listed in the chart. Maximum lift­ing capacity is restricted by the number of parts of line of
AUTOMATIC MOMENT LIMITER(AML-L).

Without outriggers “Over front”
operation should be performed within
2 degrees in front of chassis.
