Published 11-01-2020 Control # 710-00
The crane controls are located in the crane cab and are used
for all crane functions. See Figure 3-4 and Figure 3-4 for
crane cab item number (#) identification. For best control
response, run the engine at governed RPM when operating
the crane.
NOTE: The operator must be in the crane cab seat with left
armrest lowered and crane power switch ON for
the crane controls to operate.
Swing Brake Pedal
The swing brake pedal (2, Figure 3-4) is located on the left
side of the crane cab floor. Pressing the pedal down applies
brake to the turret and prevents rotation. Releasing the pedal
allows the turret to rotate freely.
Swing Brake Indicator
When the swing brake is locked, the swing brake indicator
icon will be displayed on the crane cab RCL console display
panel. For more information about the RCL icons, see
Table 7-3 on page 7-4.
Swing Brake Control Switch
The swing brake control switch (32, Figure 3-4) is located on
the left seat armrest and is a two position switch, press
forward to lock the swing brake. When the swing brake is
locked, the swing brake indicator icon will be displayed on
the crane cab RCL console display panel. Press and slide
the back half of the switch (1, Figure 3-5) to unlock the swing
brake.
The back half of the switch (1, Figure 3-5) is designed with a
locking mechanism to secure the swing brake in the locked
position and prevent accidental movement of the cab and
superstructure.
Horn Button
The horn button (33, Figure 3-4) is located on the cab seat
left joystick. The operator can use this horn to provide a
warning that the superstructure is rotating.
House Lock
The house lock (42, Figure 3-4) is used to lock the
superstructure from rotating when the boom is over the front
or over the rear of the crane. It consists of a push-pull handle
on the console and house lock control pin. The house lock is
useful for counterweight removal and assembly and should
be engaged during transport.
360° Positive Swing Lock (Optional)
If installed, the 360° swing brake pedal (40, Figure 3-4) is
located on the far left side of the crane cab floor. The pedal is
used to activate the swing lock assembly to prevent the turret
from turning at any position. Pressing the pedal down applies
brake to the turret and prevents rotation. Releasing the pedal
allows the turret to rotate freely.
House Lock Control (Pin Type)
The house lock control cable handle is located on the
console of the cab (1, Figure 3-6). The purpose of the house
lock is to lock the superstructure in position directly over the
front or rear of the crane. With the superstructure positioned
directly over the front and placed in the boom rest, push the
control handle down and turn handle clockwise. The house
lock pin (2, Figure 3-6), located near the cab, will drop into a
socket on the carrier frame, locking the superstructure in
place (3, Figure 3-6). When the control handle is turned
counterclockwise and pulled up, the pin is pulled out of the
socket, unlocking the superstructure. Turn the handle on the
cable clockwise to secure the superstructure in the unlocked
position.
CAUTION
Do not actuate the Swing Control Lever while the Swing
Brake is engaged, as the turret may push through the
brake. Damage to the swing brake can occur.
