SWIVEL JOINT
The swivel joint is located at the slew center of the ma-
chine and has the role of continuing to connect the oil cir-
cuit regardless of the slew angle of the upper frame.
A number of ports (3) equal to the number of fluid circuits
is provided on a hub (1) and shaft (2) that are mutually
rotatable. Grooves used as oil channels are processed
into the inner periphery of the hub (1) and the outer pe-
riphery of the shaft (2). A seal (4) is applied to the top and
bottom of the peripheral grooves. The oil flowing from the
port (3) continues to flow through the oil pressure chan-
nel (5) between the hub (1) and shaft (2) to enable con-
tinued connection of the circuit located between the slew
assemblies without being blocked due to rotation.
Selector
The swivel joint is equipped with a selector valve that can
be used to switch between separate circuits. The selec-
tor valves switches between the blade cylinder and the
spanner cylinder.
When the spool (2) of the selector (1) is set to the left, port
P of the selector (1) is connected to port E of the swivel
joint (3). This allows the oil from the control valve to flow
into the dozer blade cylinder.
When the spool (2) of the selector (1) is moved to the
right, port P of the selector (1) is connected to port G of
the swivel joint (3). This allows the oil from the control
valve to flow into the spanner cylinder.
