Overview of
KWT 651
extension arm
Extension arm is equipped with independent hydraulics with oil cooler and oil tank (
9
). Rotor’s
drive and extension arm control is possible owing to own hydraulic pumps assembly driven by multiplier
(
10
), transmitter’s shaft without coupling and tractor’s PTO.
Controlling extension of telescopic
extension arm is done directly from the tractor's hydraulics (
KWT 650, CAMEL 900
with mechanical
control) by means of telescope actuator (
13
), and extension arms are moved with hydraulic actuators
(
1
and
2
).
Controlling operation of extension arms is performed from
tractor’s cabin with use of control
panel (
15
), equipped with a cylinder control handle and a joystick (
1, 2, 4
and
14
). With use of
corresponding handles, the operator can set position of machine’s movable assemblies.
Use of cylinder (
14
) controlled rotor (
7
) enables extension arm to be set in transport position.
Working extension arms are protected against overloads by gauge plate cylinder (
14
) equipped with
sweep valve (item
6.5.7). While head’s cylinder (
4
) acts as head’s rotation (
6
).
CAUTION!
Extension of telescopic extension arm causes shifting of centre of gravity of the
set (tractor, machine) what may cause alternation of its stability. It is
recommended to extend the extension arm just above the ground.
