LOAD CHART (Contd)
Rated loads are for lift crane service only.
Do no operate at a radius or boom length where capacities are not listed. At these positions, the machine may
overturn without any load on the hook.
The maximum load which can be telescoped is not definable because of variations in loadings and crane
maintenance, but it is safe to attempt retraction and extension within the limits of the capacity chart.
When either boom length or radius or both are between values listed, the smallest load shown at either the next larger
radius or boom length shall be used.
10. For safe operation, the user shall make due allowances for his particular job conditions, such as: soft or uneven
ground, out of level conditions, high winds, side loads, pendulum action, jerking or sudden stopping of loads,
hazardous conditions, experience of personnel, two machine lifts, traveling with loads, electric wires, etc. Side pull on
boom is extremely dangerous.
11. Handling of personnel from the boom is not authorized except with equipment furnished and installed by Grove
12. Keep load handling devices a minimum of 18 inches (45.7 cm) below boom head at all times.
13. The boom angle before loading should be greater than the loaded boom angle to account for deflection.
14. Capacities appearing above the bold line are based on structural strength and tipping should not be relied upon as a
15. The LMI is calibrated to include originally furnished hookblock, auxiliary boom nose and overhaul ball as an integral
part of the machine.
16. Load indicating device meets SAE J376 Section 4.2 accuracy requirements for loads on hook from 9,000 to 80,000
Operating Radius: Horizontal distance from a projection of the axis of rotation to the center of the vertical hoist line or
tackle with load applied.
Loaded Boom Angle (Shown in Parenthesis on Main Boom Capacity Chart): is the angle between the boom base
section and the horizontal, after lifting the rated load at the rated radius with the rated boom length.
