Maximum dynamic retard setup

�� 4 612 kW

Load/Dump Brake Apply

Through activation of a switch by the operator, a solenoid is

energized, sending full brake pressure to apply the rear wet disc

brakes� For use during the load and dump cycles�

HI-TECH ROPS / FOPS CAB

New Hi-Tech ROPS / FOPS Cab

ROPS and FOPS comply with ISO3471, SAE J1040-May 94 and ISO3449�

A three-point rubber iso-mount arrangement to the high-arch cross

member minimizes vibration transfer to the operator compartment�

Drive Monitoring System

A new color LCD has been engineered onto the dashboard of the

EH5000ACII� All lights, gauges and indicators are provided in one location,

bringing ease of operation to the operator�

Camera Monitoring System

Included as standard visibility equipment, an analog monitor has been

mounted to the upper console to display live camera information of the

rear, front bumper, and right front tire area�

Comfort and Ease of Operation

The enlarged cab adequately fits a full size trainer’s seat and provides

more overall comfort� Ample visibility is provided by large glass sections

in doors and windows� An ergonomic shift lever that is positioned for

ease of operation also increases operator comfort� Heating capability

of 40 000 BTU/hr, and cooling capability of 30 500 BTU/hr to provide

comfort in a wide range of ambients� Improved cab air ﬂow has increased

pressurization� The cab air ﬁlter element is easily accessible from behind

the front cab cover� The heating/air conditioning system provides an LCD

display with push button control� A new parking brake alarm will sound

if the parking brake switch is not in the applied position while the engine

is running and the operator is not sitting in the drivers seat� Optional

electric windows are available for both cab doors� The window control

is available to the operator and rider as the switches are mounted to the

center console� Cab interior sound pressure level measured according to

ISO6394:1998 is 79�3 dB(A)�
