TECHNICAL DATA
PDR
ELECTRICAL SYSTEM
All power is routed via “SB” type connector (standard) to
primary fuse protection, where power then is separated to
drive and lift system subcircuits.
Modular drive control panel has premium, industrial-grade
contactors with replaceable silver-alloy tips.
All cables and wiring are color coded and/or numbered for
easy service tracing.
High-torque, Class H insulated drive motor has copper-
graphite brushes for peak electrical efficiency and long life.
Hydraulic pump motor(s) are specially selected for peak
electrical efficiency at specific torque and rpm lift pump
requirements.
Driver-control-module circuits are routed to the control head
via multiple conductor cable.
PDR-20: 2,000 lb. capacity at 24” load center. Standard
equipment includes Job-Mated, steel-clad, 12-volt, 450 amp.
hour at 6 hr. rate battery (5.238 kwh) and separate, fully
automatic 65 amp. charger. 24-volt units include steel-clad
300 amp. hour at 6 hr. rate battery (6.924 kwh) and 40
amp. fully automatic charger.
PDR-30: 3,000 lb. capacity at 24” load center. Standard
equipment includes Job-Mated, steel-clad, 12-volt, 510 amp.
hour at 6 hr. rate battery (5.934 kwh) and separate, fully
automatic 65 amp. charger. 24-volt units include steel-clad
340 amp. hour at 6 hr. rate battery (3.954 kwh) and 40
amp. fully automatic charger.
STRUCTURAL SYSTEM
Mast construction is interlocked channel and I-beam, rolled of
premium-grade steel specifically for lift truck use.
Fully rollered inner mast and lift carriage.
Forged, ITA undertapered forks are standard. Full upset heel
standard.
Unit-construction chassis, mast, and straddles form an
integral, welded, steel structure built to take heavy-duty use by
distributing stresses. All surfaces prone to receive accidental
impact are heavy gauge steel plate. Continuous welding is
used throughout the chassis at all critical points.
Reach Mechanism
Heavy-duty, pantagraph-type reach mechanism extends 24”.
Dual reach and tilt cylinders with chrome plated rods are used
on all units.
DRIVE SYSTEM
The entire drive train steers the truck via a bearing-mounted
pivot tube. Pivot tube is mounted to internal structural
member for maximum protection.
Direct drive full oil bath transmission operates through 22:1
gear reduction in ductile-iron transmission case with heat-
treated, alloy steel gears and premium industrial bearings.
HYDRAULIC SYSTEM
3-spool infinitely variable valve provides full-range operator
control over lift, extension and tilt.
Gear pumps are matched to lift cylinders to provide good lift
performance at modest power-draw levels.
Full system filtration is provided on the intake side of the
pump which prevents foreign matter from entering any part of
the system.
Relief valve protects entire system from overload.
Pressure-compensating flow control valve at base of lift
cylinder regulates lowering speed.
Reservoir comes equipped with highly efficient sump filter cap
and dipstick.
SAFETY FEATURES
Automatic speed cut-off circuit locks out high speed when
forks are elevated above 18”.
Large direction reversing “Belly-button” impact switch
provides operator protection when maneuvering. Upon body
contact, switch activates low speed in the opposite direction.
“Dead-man” mechanical braking action occurs when spring
loaded control handle is released, turning off electrical power
and applying disc brake in the process.
Externally-mounted battery connector is accessible to operator
for emergency power disconnect.
All power and control circuits are fuse-protected.
CERTIFICATION
All units certified to be in compliance with the Occupational
Safety and Health Act (OSHA).
