TM 5-3810-302-10
LOAD CAPACITY CHARTS REPRESENT THE ABSOLUTE MAXIMUMAL-
LOWABLE LOADS, WHICH ARE BASED ON EITHER TIPPING OR STRUC-
TURALLIMITATIONS UNDER SPECIFIC CONDITIONS. KNOWING THE PRE-
CISE RADIUS OF OPERATION, BOOM LENGTH, AND ANGLE SHOULD BE A
PART OF YOUR ROUTINE PLANNING AND OPERATION. ACTUAL LOADS,
INCLUDING NECESSARY ALLOWANCES, SHOULD BE KEPT BELOW
THESE CAPACITY FIGURES.
IF THE CRANE IS NOT LEVEL, LOAD CAPACITIES ARE REDUCED WHEN
LIFTING ON THE LOW SIDE. DON'T BE MISLED BY OPTICAL ILLUSIONS.
USE YOUR BUBBLE LEVEL.
IF YOU SHOULD ENCOUNTER A TIPPING CONDITION, START LOW-
ERING THE LOAD WITH THE HOIST LINE AND RETRACTOR ELEVATE
THE BOOM TO BRING THE LOAD IN. NEVER LOWER OR EXTEND
THE BOOM, THIS WILL AGGRAVATE THE CONDITION.
WHEN USING THE HOIST AVOID SUDDEN STOPS. INCREASED LOAD-
ING WILL RESULT AND COULD CAUSE TIPPING OR A STRUCTURAL
FAILURE TO OCCUR.
EVEN IF A HYDRAULIC LINE MAY BE SHEARED OR BROKEN ON
THE LIFT OR EXTENSION CYLINDERS, THE CRANE WILL STILL
FUNCTION SUFFICIENTLY TO GET THE LOAD DOWN.
MAXIMUM LIFTING CAPABILITY IS AVAILABLE AT THE SHORTEST
RADIUS, MINIMUM BOOM LENGTH AND HIGHEST BOOM ANGLE.
2-65
