The following information comes directly from the load chart posted in the superstructure cab. This information is of the up
most importance to ensure safe and efficient crane operation.
NOTES TO LIFTING CAPACITIES.
Do not exceed any rated lifting capacity. Rated lifting capacities are based on freely suspended loads with the
machine leveled and standing on a firm supporting surface. Ratings with outriggers are based on outriggers being
extended to their maximum position and tires raised free of crane weight before extending the boom or lifting
Practical working loads for each particular job shall be established by the user depending on operating condition to
include: the supporting surface, wind and other factors affecting stability, hazardous surroundings, experience of
personnel, handling of load, etc. No attempt must be made to move a load horizontally on the ground in any
Operating radius is the horizontal distance from the axis of rotation before loading to the centerline of the vertical
hoist line or tackle with loads applied.
"On Rubber" lifting (if permitted) depends on proper tire inflation, capacity and condition. "On Rubber" loads may
be transported at a maximum vehicle speed of 2.5 mi/hr (4 Km/hr) on a firm and level surface under conditions
Jibs may be used for lifting crane service only. Jib capacities are based on structural strength of jib or main boom
and on main boom angle.
Operation is not intended or approved for any conditions outside of those shown hereon. Handling of personnel
from the boom is not authorized except with equipment furnished and installed by Grove Manufacturing Company.
For clamshell or concrete bucket operation, weight of bucket and load must not exceed 80% of rated lifting
Power-telescoping boom sections must be extended equally at all times.
Long cantilever booms can create a tipping condition when in extended and lowered position.
The maximum load which may be telescoped is limited by hydraulic pressure, boom angle, boom lubrication, etc.
It is safe to attempt to telescope any load within the limits of rated lifting capacity chart.
