OPERATING CONTROLS & PROCEDURES NBT40 SERIES OPERATOR MANUAL
Swing Brake Pedal
The swing brake pedal (2, Figure 3-3) is located on the left
side of the crane cab floor. The brake pedal is used to
activate the swing brake and momentarily hold the turret in
position.
Boom Telescope Pedal (Optional)
The telescope foot pedal (3, Figure 3-3) is used to extend
and retract the boom when the crane is equipped with an
auxiliary hoist. Rock the pedal forward to extend the boom
and rock back to retract the boom.
Foot Throttle Pedal
The foot throttle (4, Figure 3-4) is located on the crane cab
floor and is used to control the engine speed. Depress the
foot throttle to accelerate the engine speed and release to
return to idle.
The hand throttle (11, Figure 3-4) must be positioned as
shown in Figure 3-6 to operate the foot throttle properly.
Display Panel
The display panel (5 Figure 3-3) is for the Rated Capacity
Limiter (RCL), see operating instructions and screen
displays in this manual.
The RCL provides the crane operator with the information
required for the crane to perform safely within its design
parameters. The RCL displays information on length and
angle of boom, working radius, rated load, and total weight
being lifted.
The RCL continuously monitors these parameters and
provides the operator with an updated readout of the crane
status. If a nonsafe condition is approached, the RCL warns
the operator with an alarm and locks out the crane functions
that can aggravate the situation.
