Setup
The edge of the eccentric does not form a concentric
radius (constant distance between outer edge and
rotation axis) around the rotation point of the disc
but an eccentric radius (variable distance between
outer edge and rotation axis). The distance between
the respective surface location of the weight plate
(load) and the rotation point determines the length
of the lever arm with which the weight pulls the
plate. This distance is called the load arm. In
contrast, the length of the lever arm (against which
the trainee works) determines the so-called moment
arm. According to the lever principle (Load x load
arm = moment x moment arm), an eccentric
transfers a high torque (more load) on the rotation
axis if the weight is transferred via a long load arm
to the rotation axis and vice versa (i.e. via a point of
the disc with a longer distance to the rotation point). Thus, the maximum strain on the
muscles may be realised by a high torque already at the beginning of the motion and will be
maintained almost until the final position is reached.
To meet individual needs, the moment arm may be adjusted in relation to the eccentric to
allow for strain adjustment by modifying the link positions.
Some machines of the VECTOR Kraft Line are not equipped with an eccentric. This is due
to the vertical (VECTOR LAT PULL, VECTOR SHOULDER ABDUCTION, VECTOR
SHOULDER PRESS, VECTOR PULL UP/DIP, VECTOR SEATED DIP) or horizontal
(VECTOR CHEST PRESS, VECTOR SQUAT PRESS, VECTOR BACK PULL, VECTOR
BUTTERFLY REVERSE, VECTOR ABDOMINAL TORSION, VECTOR ABDUCTOR,
VECTOR ADDUCTOR ) exercise motion.
6.7 Function test
⊗
Check if all handling parts are locked properly before training. Make sure there
are no loose or badly mounted handling parts.
⊗
Check the cable and wires for damage.
⊗
Check moving parts (steel cables, Kevlar cables, rollers) for proper function.
⊗
Check the rests and paddings for damage.
⊗
Check if all adjustable parts function properly.
