[NOTICE]
There is a case that the appearance and so on
differ from the parts for this machine. Although there
is not so much difference in functions and
disassembly procedures, make sure of the serial
number of this machine and the part sales unit
described in the parts catalog before starting
disassembling operations.
1. Construction and function
1. The boom length/angle detector consists of a
spiral spring, cord, reduction gear, potentiometer
(for boom length detection), and boom angle
detector.
2. The cord wound on the drum is unwound and
rewound by the spiral spring as the boom extends
and retracts. The resultant drum rotation is
reduced by the reduction gear, which in turn
rotates the shaft of the potentiometer.
3. The electric resistance of the potentiometer shaft
varies proportional to the reduction of the shaft
rotation, and the change in electric resistance is
transmitted to the AML main body to detect the
boom length.
