- 3266 kg (7200 lb) per capacity chart
• 204 kg (450 lb) deduct for 30 - 54 ft jib stowed at 18.9 m
(62 ft) boom length
• 117.9 kg (260 lb) added per the table to compensate for
the effects of the jib stowed on the main boom during the
stability test.
• Stability Test Load (30 - 54 ft jib stowed):
• (7200 -450 +260) x 1.176 = 8244 lb*
- (3266 -204 +117.9) x l.176 = 3740kg*
NOTE: *Includes weights of slings and hook block
5. Over the side:
• Assemble the first stability test load as described
above near the crane.
• Measure the load radius from the center of rotation
directly to one side of the machine.
• Extend the boom to the specified boom length
• Lift the stability test load just slightly off the ground
(not over 0.3 m [1 ft]).
• Slowly boom down while hoisting up to move the
load out to the load radius.
• Move the load very slowly when approaching the
load radius so the stability test load does not swing
out past the load radius. If the stability test load can
be kept from contacting the ground at the load
radius, the unit is stable over the side tested.
• Slowly rotate the load 360° to ensure that the
stability test load is stable directly over both sides,
the back, and the front.
6. Over the rear:
• Assemble the second stability test load as
described above near the crane
• Measure the load radius from the center of rotation
directly to the rear of the machine.
• Extend the boom to the specified boom length and
lift the stability test load just slightly off the ground
(not above 0.3 m [1 ft]).
• Boom down while hoisting up to move the stability
test load out to the load radius.
• Move the load very slowly when approaching the
load radius so the stability test load does not swing
out past the load radius. If the stability test load can
be kept from contacting the ground at the load
radius, the unit is stable over the rear of the unit.
• Slowly rotate the stability test load 360° to ensure
that the load is stable directly over both sides, the
back, and the front.
7. If unit is unstable, counterweight needs to be added.
• Add weight at the front bumper or at the front of the
subbase, if the crane is unstable over the rear.
• Add weight close to the centerline of rotation if the
crane is unstable over the side.
