Example 2
Assume a load of 9000 lbs (4082 kg) at 10 ft (3.04 m) radius
on the ground beside the truck to be picked up, swung over
and placed on the truck bed at an 8 ft (2.43 m) radius from
the crane. Crane is reeved for single part.
1. Weight of load and load handling equipment.
2. Starting Radius = 10 ft (3.04 m)
3. Ending Radius = 8 ft (2.43 m)
4. Refer to crane load chart.
The crane capacity at the 10 ft (3.04 m) radius is 18,900 lbs
(8,573 kg). At the 8 ft (2.43 m) radius, the capacity is
19,750 lbs (8,960 kg).
The crane capacity is adequate.
5. Refer to hoist load chart.
The capacity of a 1 part line is 7700 lbs (3492 kg), which is
less than load to be lifted.
NOTE: Crane must be reeved for 2 part to lift the 9,000 lbs
(4082 kg) load.
Two part hoist capacity is 15,400 lbs (6985 kg)
After reeving for 2 part line the new Step 1 calculation is the
weight of load and load handling equipment.
Example 3
A load of 1500 lbs (680 kg) is to be lifted from the roof of a
building at a radius of 30 ft (9.14 m) and a height of 80 ft
(24.38 m) and placed on the ground on the other side of the
truck at a radius of 40 ft (12.19 m).
1. Weight of load and load handling equipment.
2. Starting Radius Given = 30 ft (9.14 m)
3. Ending Radius Given = 40 ft (12.19 m)
4. Refer to Crane load chart.
To reach the load on the roof, the jib must be utilized to clear
the roof with the load.
Both the retracted 23' jib length and extended 41' jib length
have the necessary capacity at a 30' (9.14 m) radius. Only
the retracted 23' jib has the capacity at the 40' (12.19 m)
radius to accomplish the task.
Starting Point: With the 23 ft (7 m) jib deployed and the boom
fully extended, the capacity is 2,450 lbs (1111 kg) at a 30 ft
(9.14 m) radius and boom angle of 72.1°.
Ending Point: With the main boom still fully extended, the
capacity is 1,800 lbs (816 kg) at a radius of 40 ft (12.19 m)
and boom angle of 65.4°.
NOTE: The capacity of the jib remains the same even with
the main boom retracted. Operate with jib by radius
when main boom is fully extended and operate with
jib by boom angle when main boom is not fully
extended. Do not exceed rated jib capacities at any
reduced boom lengths.
5. Refer to hoist load chart.
The capacity of a 1 part lines 7700 lbs (3492 kg) which is well
above the 1,680 lbs (762 kg) to be lifted.
NOTE: The HCA Load Range Gauge does not provide
accurate indication of overload conditions when
operating with a jib deployed. The HCA will not
prevent the crane from being operated in an
overload condition. The Jib is equipped with a jib
load limiting device which will prevent the jib from
being operated in an overload condition.
The operator should proceed to lift the load as smoothly as
possible.
Load = 9000 lb (4082 kg)
1 Part Load Block = 150 lb (68 kg)
Sling = 50 lb (22 kg)
Total Load = 9200 lb (4173 kg)
Load = 9000 lb (4082 kg)
1 Part Load Block = 200 lb (90.7 kg)
Sling = 50 lb (22 kg)
Total Load = 9250 lb (4195 kg)
Load = 1500 lb (680 kg)
1 Part Load Block = 150 lb (68 kg)
Sling = 30 lb (14 kg)
Total Load = 1680 lb (762 kg)
CAUTION
Do not attempt to deploy the jib until reading and
understanding jib operation information found later in this
section of the manual.
