LM-series fork-mountable booms 01/11
FIG. 4B: LM-EBT – 4K, 6K & 8K CENTERS OF GRAVITY AND MAXIMUM LOAD RATINGS FOR
VARYING LOAD ATTACHMENT POINT AND BOOM EXTENSION COMBINATIONS
The center of gravity of the boom ranges between a minimum of 34.5 inches and a maximum of 54.5 inches from
the outer edges of the fork pockets. As shown in the diagram above, the horizontal center of gravity may be located at
any point from RHCG to EHCG:
 RHCG [stands for “Retracted horizontal
center of gravity”]: boom fully retracted, and load attached at position A,
the center of gravity is located 34.5 inches (~88cm) from the outer edges of the fork pockets;
 Extended horizontal cente
r of gravity (EHCG): fully extended with a load attached at position J, the center of
gravity is located 54.5 inches (~138cm) from the outer edges of the fork pockets.
 All other combinations of boom extension and load position produce a horizontal center of gravity located
somewhere between RHCG and EHCG.
