Twistlock Actuators
Four twistlock actuators are mounted inside the
forward and rear lateral tubes of the bed
assembly. Each actuator is connected to the
center of the twistlock and receives hydraulic
pressure from the twistlock manifold assembly
as commanded by the twistlock controls. Each
actuator is equipped with an adjustable clevis to
allow for adjustment of the twistlock head
angle.
CONTROLS AND INDICATING
SYSTEMS
The controls required to operate the body
assembly and integrate with the existing chassis
controls are located throughout the entire
vehicle and bed assembly. The MCC35 adds
several new control components and indicators
to increase safety and reliability for the entire
system.
The control components consist of an additional
body assembly, ECM (Electronic Control
Module), hoist lever mounted midpoint override
switch, remote tailgate restraint operation
switches, tailgate restraint control fault indicator
lamp, in-cab twistlock control switch, twistlock
position sensors, twistlock position status
indicator lamp and a roof mounted twistlock
status beacon.
Body Assembly ECM
The unit is located under the floor of the cab
under the operator’s seat. This additional ECM
is integrated to existing chassis ECMs with
cable harnesses and loaded with a MCC35
specific software flash file.
The ECM controls and monitors hoist lever
position, hoist lever override switch, remote
body operation switch panel, bed position
sensor, in-cab twistlock switch, twistlock
position sensors, twistlock status indicating
beacon,
transmission and hoist valve.
